About the NetWorker product
The EMC® NetWorker® product is a storage management software suite that provides
backup, recovery, and other services to machines with a wide variety of operating systems
and data types. NetWorker products for different operating systems are interoperable. This
provides the flexibility to design a storage management system that works best with the
current computing environment.
The NetWorker software is distributed in these formats:
◆
In a media kit that contains the software and electronic documentation for several
related NetWorker products.
◆
As a downloadable archive file from the EMC Online Support Site web site.
The NetWorker product has these components:
◆
NetWorker client
◆
NetWorker storage node
◆
NetWorker server
◆
NetWorker management console server
◆
NetWorker language packs
◆
NetWorker license manager
NetWorker client
The NetWorker client software communicates with the NetWorker server and provides
client initiated backup and recover functionality. The NetWorker client software is installed
on all machines that are backed up to the NetWorker server.
Introduction
13
Introduction
NetWorker storage node
Data is backed up directly to devices local to a NetWorker server or remotely to a
NetWorker storage node. A storage node controls storage devices such as tape drives, disk
devices, autochangers, and silos. The NetWorker server is a local storage node.
A remote NetWorker storage node:
◆
Off-loads most of the data movement involved in a backup or recovery operation from
the NetWorker server
◆
Improves performance.
◆
Requires high I/O bandwidth to manage the transfer of data transfer from local clients,
or network clients to target devices.
◆
Can be a different operating system from the NetWorker server.
NetWorker server
The NetWorker server provides services to back up and recover data for the NetWorker
client machines in a datazone. The NetWorker server can also act as a storage node and
control multiple remote storage nodes.
Index and media management operations are some of the primary processes of the
NetWorker server:
◆
The client file index tracks the files that belong to a save set. There is one client file
index for each client.
◆
The media database tracks:
• The volume name.
• The location of each save set fragment on the physical media (file number/file
record).
• The backup dates of the save sets on the volume.
• The file systems in each save set.
◆
Unlike the client file indexes, there is only one media database per server.
◆
The client file indexes and media database can grow to become prohibitively large
over time and will negatively impact backup performance.
◆
The NetWorker server schedules and queues all backup operations, tracks real-time
backup and restore related activities, and all Console server communication.
This information is stored for a limited amount of time in the jobsdb database which
for real-time operations, has the most critical backup server performance impact. The
data stored in the jobsdb database is not required for restore operations.

EMC NetWorker Release 8.0 Cluster Installation Guide
Introduction
NetWorker Management Console server
The NetWorker Management Console (NMC) server or Console server, is a Java based web
application server that provides centralized:
◆
Management of multiple NetWorker servers across multiple datazones.
◆
Monitoring of multiple NetWorker servers across multiple datazones.
◆
Backup reporting of multiple NetWorker servers across multiple datazones.
The Console server:
◆
Is installed on an AIX, Linux, Solaris, or Microsoft Windows host.
◆
Is accessed through a graphical user interface on a host with a web-enabled browser
that has the specified version of Java Runtime configured.
Multiple users can access the Console server concurrently from different browser
sessions. A machine that hosts the web-enabled browser can also be a NetWorker
client, server, or storage node.
◆
Embeds the Apache server 2.2.21 software.
The apache software is used to:
• Download of the Console jar files.
• Startup of the Console server daemon or service.
◆
Embeds the Sybase SQL Anywhere software.
The Console server database is a Sybase SQL Anywhere database.
NetWorker datazone
A NetWorker datazone is a single NetWorker server and its client and storage node
machines.
NetWorker daemons
The NetWorker software requires processes on Windows or daemons on UNIX to run on the
system and facilitate NetWorker operations in the datazone.
Table 1 on page 15 lists the NetWorker daemons for each of the software components.

Introduction
Consider the following:
◆
The nsrmmd process or daemon is present when one or more devices are enabled.
◆
The nsrmmgd process or daemon is present on the NetWorker server when a library is
enabled.
◆
The nsrlcpd process or daemon is present on a NetWorker server and storage nodes
with an attached library.
◆
The nsrcpd process or daemon is present on the NetWorker server during a client push
software upgrade.
◆
The Console server daemon, gstd starts these additional processes:
• dbsrv12 — the SQL Anywhere database process.
• httpd — there will be 2 or more httpd processes.
gstsnmptrapd — an optional process that is present on the Console server when SNMP
Trap monitoring is configured for a Data Domain system.
•
Supported storage devices
Storage devices are attached to a NetWorker server or to a designated storage node.
The NetWorker software supports a variety of media types and devices including:
◆
Disk devices
◆
Stand-alone tape devices
◆
Tape devices in an autochanger or silo tape library
The term autochanger refers to a variety of backup devices:
• Autoloader
• Carousel
• Datawheel
• Jukebox
• Library
• Near-line storage
The NetWorker 7.3 (and Later) Hardware Compatibility Guide provides the most up-to-date
list of supported devices.
NetWorker cluster services
In cluster setups on all supported cluster platforms, the cluster services must be running
before the NetWorker services start. When the cluster services start after Networker, the
NetWorker software will exhibit undesirable behavior.

EMC AutoStart for Microsoft Windows Installation
Update the NetWorker software
To update the NetWorker server software in an AutoStart environment:
1. Start the EMC AutoStart Console and take the NetWorker server Cluster resource group
offline.
2. Rename the NetWorker.clustersvr file to NetWorker.nocluster.
This file is typically located in %SystemDrive%\Program Files\EMC NetWorker\nsr\bin.
3. Upgrade the NetWorker software. The NetWorker Installation Guide provides
instructions.
4. Stop the NetWorker Backup and Recover Server service.
5. Open the NetWorker Backup and Recover Server service properties and change the
Startup type from Automatic to Manual.
6. Rename the NetWorker.nocluster file back to NetWorker.clustersvr.
7. Repeat step 2 through step 6 on the second node of the cluster.
8. Bring the NetWorker server Cluster resource group back online.
Update to the NetWorker software in an AutoStart 5.4 and later cluster
Beginning in AutoStart release 5.4, AutoStart no longer provides the nwclust.pl script. The
NetWorker software includes the script, and as a result the location of the script has
changed, and the lcmap script must be updated to point to the new location.
When updating the NetWorker software in an AutoStart 5.4 or later cluster environment,
reconfigure the AutoStart cluster to point the generated lcmap script to the correct
location of the nwclust.pl script:
1. Run lc_config -r.
2. Run lc_config.
The following example shows the generated lcmap script on Windows after the cluster
configuration:
SET FT_DIR=C:\Program Files\EMC\AutoStart\eas54
SET FT_DOMAIN=eas54
"C:\Program Files\EMC\AutoStart\eas54\bin\ftPerl" "C:\Program
Files\EMC NetWorker\nsr\bin\nwclust.pl"
For a new installation of the NetWorker software, these steps for upgrading do not apply.
“Install only the NetWorker client software in a cluster” on page 31 provides instructions
on installing the NetWorker software in an AutoStart cluster environment.

EMC AutoStart for Microsoft Windows Installation
Install a NetWorker virtual server
To install and configure the NetWorker software as a highly available service in a cluster,
complete these tasks:
◆
“Task 1: Ensure that the EMC AutoStart software is installed” on page 24
◆
“Task 2: Install the NetWorker software in a cluster” on page 24
◆
“Task 3: Promote at least one secondary cluster node to primary” on page 25
◆
“Task 4: Create the resource that will become the managed shared disk” on page 25
◆
“Task 5: Define the NetWorker server as highly available” on page 25
◆
“Task 6: Configure the NetWorker virtual server” on page 28
◆
“Task 7: Configure the clients of the NetWorker cluster server” on page 29
◆
“Task 8: Register NetWorker licenses for cluster server failover” on page 30
Task 1: Ensure that the EMC AutoStart software is installed
Ensure that the AutoStart software is installed. The AutoStart documentation provides
detailed installation instructions.
Task 2: Install the NetWorker software in a cluster
On each node in the cluster, install NetWorker server software in the same location on a
private disk, for example, in %SystemDrive%\Program Files\EMC NetWorker\nsr.
To install the NetWorker software:
1. Log in as administrator on one node.
2. Install these NetWorker software packages on each node in the cluster:
• Client
• Storage Node
• Server
• Man pages
The EMC NetWorker 8.0 Installation Guide provides detailed installation instructions.
24
EMC NetWorker Release 8.0 Cluster Installation Guide
EMC AutoStart for Microsoft Windows Installation
3. Obtain the NetWorker hostid:
a. Launch the NetWorker Management Console software.
b. From the Administration windows, select Registration from the Configuration
menu.
c. Right-click NetWorker/10 Eval and select Properties.
The value that is displayed in the HostID field is the hostid for the node on which
NetWorker server is running. This HostID is required later in the installation.
4. Repeat step 1 through step 3 on the second node.
Task 3: Promote at least one secondary cluster node to primary
Always run two primary controllers. Promote at lease one secondary node to the primary
by using the AutoStart Console. If one node fails, the other can be online automatically
with all data. The AutoStart documentation provides detailed instructions.
Task 4: Create the resource that will become the managed shared disk
On one of the cluster nodes, create a folder to use later as the managed, shared disk. For
example, create the folder s:\nsr.
Do not share the folder at this point, or the installation will fail. If the AutoStart software is
already installed and a managed shared disk already exists, remove the share property
now.
Task 5: Define the NetWorker server as highly available
To define the NetWorker server as a highly-available application, run the lc_config script
on each node. By configuring the NetWorker server as a highly-available application, you
create a NetWorker cluster group resource. This allows the NetWorker server to run in
cluster mode (that is, with failover capability).
To run the lc_config script:
1. Log in as administrator.
2. Add the virtual hostnames to the hosts file on each cluster node (located in
%SystemRoot%\system32 # # \drivers\etc).
3. Ensure that all node names to be used in the cluster, both the physical nodes and the
virtual nodes, can be resolved using DNS. To verify that the node names can be
resolved by using DNS, type:
nslookup node_name
Install a NetWorker virtual server
25

4. Start the NetWorker Backup and Recover Server services.
If you are upgrading NetWorker software or reinstalling after a partial uninstall of the
NetWorker software, the lc_config script prompts for a command to keep, rename or
delete each of the old server configuration files. It is safe to delete the old files.
To delete a file, type d when prompted. After you finish typing the choices for each of
the old configuration files, continue with step 5 .
5. Run the lc_config script.
When the lc_config script runs, you are prompted to type the information listed in
Table 2 on page 22.
lc_config
C:\Program Files\EMC NetWorker\nsr\bin>lc_config
Checking for C:\Program
Files\EMC NetWorker\nsr\bin\lcmap.bat
Checking for C:\Program Files\EMC

Enter shared nsr dir:s:\nsr
Enter the EMC Fulltime Autostart domain name:galaxy
Enter the directory in which your EMC Fulltime Autostart software is
installed (typically something like C:\galaxy):
C:\Program Files\EMC\AutoStart\galaxy
6. Type y to confirm that the information is correct.
If required to make corrections, type n. When lc_config script runs again, retype the
information:
You entered the following data:
Nsr Dir = s:\nsr,
EMC Fulltime Autostart domain = galaxy
EMC Fulltime Autostart software location = C:\Program
Files\EMC\AutoStart\galaxy
Is this OK [y/n]y
7. Stop the NetWorker Backup and Recover Server services.
8. Edit the nw_nt.aam5.imp file and modify these fields:
• Virtual hostname
• Physical cluster node names
• Shared drive letter
The #NW customise label tag appears before each field that requires modification.
26

9. On one node only, go to %SystemDrive%\Program Files\EMC NetWorker\nsr\bin and
run the following command. For example, if the AutoStart domain name is galaxy,
type:
“C:\Program Files\EMC\AutoStart\galaxy\bin\ftcli” -d galaxy -c
"import nw_nt.lc.imp"
This information is displayed:
C:\Program Files\EMC NetWorker\nsr\bin>"C:\Program

nw_nt.aam5.imp"IP Address "guiro" Created
Process Class "nsrd" Created
Process "NSRserver" Created
Configuration "NSRserver" Created
Process Class "nsrexecd" Created
Process "NSRexecd" Created
Configuration "NSRexecd" Created
Data Source "networker_ds" Created
Resource Group "networker" Created
OK
10. Use the AutoStart Console to:
a. Verify that the NetWorker Server resource was created.
b. Share the managed shared disk (for example, s:\nsr).
c. Bring the NetWorker virtual server online.
d. Select the disk to be used for NetWorker virtual server storage and set the disk to
be managed as a shared storage for each physical node in the cluster.
11. For each physical node in the cluster, ensure that the AutoStart Console user account,
NT AUTHORITY\SYSTEM is included in the valid user list with administrator access.
12. Ensure that the value of the environment variable for the administrator user
FT_DOMAIN is set to the AutoStart domain name.
Install a NetWorker virtual server
27
EMC AutoStart for Microsoft Windows Installation
13. From one node in the cluster:
a. Log in as administrator.
b. Ensure that the data source for the NetWorker virtual server is managed by the
AutoStart Management Console.
The data source for the NetWorker virtual server is defined as networker_ds in the
NetWorker resource group.
c. Run this script from the directory where the NetWorker software was installed:
nwinst.bat
The AutoStart documentation provides instructions on using the AutoStart Console.
AutoStart warning messages are generated when running the nwinst.bat script. The
messages do not indicate that any AutoStart functionality is affected, and should be
ignored.
This is an example of an Autostart warning message:

Task 6: Configure the NetWorker virtual server
To configure the NetWorker server:
1. Log in as administrator on the cluster node that is currently running the NetWorker
server resource group.
2. Start the NetWorker Console software.
3. From the Administration window, select Properties from the File menu.
a. For the Administrator attribute, add entries for any cluster nodes that are not
already listed. For example:
root@hostname
b. Click Ok.
28
EMC NetWorker Release 8.0 Cluster Installation Guide
EMC AutoStart for Microsoft Windows Installation
4. Restrict the set of NetWorker servers that can back up a particular client. Edit the
%SystemDrive%\Program Files\EMC NetWorker\nsr\res\servers file and add the
NetWorker virtual host as well as each cluster node to the list of servers.
Consider the following:
• If no servers are specified, any NetWorker server can backup this client.
• If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
• When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
Task 7: Configure the clients of the NetWorker cluster server
To configure each client under the NetWorker server:
1. (Optional) Define save groups.
In order for their save sets to restart after a virtual client or NetWorker server failover,
save groups must have the Autorestart attribute enabled and the Manual Restart
option disabled.
2. Make each physical client within the cluster a client of the NetWorker server.
For each physical client in the cluster:
a. Create a new NetWorker client.
b. For the Name attribute, type the name of the physical client.
3. Make each virtual client within the cluster a client of the virtual NetWorker server.
For each virtual client in the cluster:
a. Create a new NetWorker client.
b. For the Name attribute, type the name of the virtual client.
c. For the Remote Access attribute, add entries for each physical client within the
cluster. For example:
root@clus_phys1
d. For the Group attribute, select a group.
The first time the NetWorker application runs, it creates the Client resource for the
NetWorker virtual server. The NetWorker 8.0 Administration guide provides more
information.
4. Verify that the Client and Group resources are properly configured by running a test
probe. On the node where the NetWorker server resides, type:
savegrp -pv -c client_name group_name
If this test does not display the expected scheduled backups and index, create an
empty file named pathownerignore in the directory where the NetWorker savefs
command is installed. This allows a valid save set on a NetWorker client to be
scheduled for backup. For example:
Install a NetWorker virtual server
29
EMC AutoStart for Microsoft Windows Installation
On each node of the cluster, type:
echo NUL: networker_bin_dir\pathownerignore
A NetWorker scheduled save might use a default rather than a specified client index
name. To override this default, run a manual save with the -c option:
save -c client_name
5. Restrict the set of NetWorker servers that can back up a particular client. Edit the
%SystemDrive%\Program Files\EMC NetWorker\nsr\res\servers file and add the
NetWorker virtual host as well as each cluster node to the list of servers.
Consider the following:
• If no servers are specified, any NetWorker server can backup this client.
• If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
• When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
After the client configuration is complete:
◆
The NetWorker cluster server uses the IP address of the NetWorker virtual host
regardless of which cluster node currently masters the NetWorker virtual server.
◆
The NetWorker cluster server takes the identity of the NetWorker virtual server’s
hostname regardless of which cluster node is currently running the NetWorker service.
◆
The first time NetWorker software runs, it creates the client resource for the NetWorker
virtual host. Client resources must be created manually for any cluster node to be
backed up by the NetWorker virtual host.
Task 8: Register NetWorker licenses for cluster server failover
To register NetWorker licenses for cluster failover:
1. Ensure that the NetWorker virtual server is defined as part of a cluster.
2. Ensure that the NetWorker service is running.
3. Log in to the cluster node on which the NetWorker virtual server is running.
4. Create a file named hostids in the nsr\res directory.
5. Open the hostids file and add one line. For hostid values, use the NetWorker hostids
values that were derived in “Task 2: Install the NetWorker software in a cluster” on
page 24.
hostid1:hostid2
6. Restart the NetWorker virtual server by taking it offline and then bringing it back
online.
7. Register the NetWorker software for permanent use. More information is available in
the NetWorker Licensing Guide.

To install NetWorker cluster client, read and follow the procedures for these tasks:
◆
“Task 1: Install the NetWorker cluster client software” on page 31
◆
“Task 2: Configure NetWorker client software as cluster aware” on page 31
Make sure the NetWorker client software is installed on every node to be backed up in the
cluster.
Task 1: Install the NetWorker cluster client software
To install the NetWorker client software on each node in the cluster:
◆
Ensure that the operating system is updated with the most recent cluster patch.
◆
Install the NetWorker client software on the physical disk of each node in the cluster to
be backed up. More information is available in the NetWorker Licensing Guide.
Task 2: Configure NetWorker client software as cluster aware
To configure the NetWorker client software as cluster aware:
1. Make each physical client within the cluster a client of the NetWorker server. For each
physical client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the physical client.
If a physical Client is backed up to a NetWorker server outside the cluster, the name of
any virtual service that can run on the physical node must be added to the Remote
Access list of the physical Client resource.
2. Add the virtual hostnames to the hosts file on each cluster node (located in
%SystemRoot%\system32 # # \drivers\etc).
3. Make each virtual client within the cluster a client of the NetWorker server. For each
virtual client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the NetWorker server.
c. For the Remote Access attribute, add entries for each physical client within the
cluster. For example:
root@clus_phys1
d. For the Group attribute, select a group.

c. Type y to confirm the information.
6. For each physical node in the cluster, ensure that the AutoStart Console user account,
NT AUTHORITY\SYSTEM is included in the valid user list with administrator access.
Uninstall the NetWorker software
To uninstall the NetWorker software from an AutoStart environment:
1. Take the NetWorker Resource Group offline.
2. Select and delete the NetWorker Resource Group from the Current Resource Group list.
3. Select and delete the NSRserver and the NSRexecd services.
4. Select and delete the networker_ds resource.
5. Select and delete the NetWorker virtual server IP Address.
6. On each node in the cluster:
a. Log in as administrator on the computer from which the software is being removed.
b. Undo all changes to the configuration by running the following:
lc_config.exe -r
7. Uninstall the NetWorker Server software from each node. The NetWorker Installation
Guide provides instructions.
If the NetWorker software will be reinstalled to the same location, ensure that the required
files are deleted from the /bin subdirectory: NetWorker.clustersvr, lcmap.bat and
winst.bat.
Configure the NetWorker virtual server with a backup device
The NetWorker virtual server must be configured with storage node backup devices. The
storage nodes that are used by the NetWorker virtual server can be devices attached to a
remote system (external to the cluster). They can also be devices connected locally to any
of the physical nodes in the cluster. A storage node device can be a stand-alone tape
device or an autochanger. The NetWorker Administration Guide provides information
about how to configure storage nodes.
The NetWorker server requires a local backup device to save the bootstrap and the server
indexes.
32
EMC NetWorker Release 8.0 Cluster Installation Guide
EMC AutoStart for Microsoft Windows Installation
This is the recommended device configuration for a NetWorker virtual server, release 6.0
or later, that is running in a two-node AutoStart cluster:
◆
Each cluster node must be defined as a storage node for the NetWorker virtual server.
◆
In the AutoStart Console, the Preferences\’Storage Nodes attribute in the NetWorker
virtual server Client resource lists the storage nodes that are enabled to store data for
the client.
Each of the storage nodes must be listed before you can list the nsrserverhost:
1. One cluster node
2. The other cluster node
3. The nsrserverhost
The nsrserverhost must always be listed last in each client's storage node list.
NetWorker software does not allow the configuration of a storage node on a cluster node
that is running the NetWorker server binaries. Consequently, before configuring a cluster
node as a storage node, you must move the NetWorker virtual server to another node in
the cluster.
Troubleshoot the NetWorker software
These sections contain troubleshooting tips for NetWorker software in an AutoStart
environment.
Set the shutdown wait timeout values
To prevent timing problems during failover, perform this procedure to increase the
shutdown wait timeout value for the NSRserver service.
1. Start the EMC AutoStart Console and select the domain.
2. Select Resource Groups>NetWorker Resource group.
3. Select the Settings tab.
4. Select NSRserver from the list box and click Edit.
5. Increase the value for the Wait until service is stopped item.

Update the NetWorker software in an AutoStart 5.4 and later
cluster
Beginning in AutoStart release 5.4, AutoStart no longer provides the nwclust.pl script. The
NetWorker software includes the script, and as a result the location of the script has
changed and the lcmap script must be updated to point to the new location.
When updating the NetWorker software in an AutoStart 5.4 or later cluster environment,
reconfigure the AutoStart cluster to point the generated lcmap script to the correct
location of the nwclust.pl script:
1. Run networker.cluster -r.
2. Run networker.cluster.
For a new installation of the NetWorker software, these steps for updating do not apply.
“Install only the NetWorker client software in a cluster” on page 47 provides instruction on
installing the NetWorker software in an AutoStart cluster.

Task 4: Grant access to the NetWorker virtual server
Before a NetWorker server can back up a client, the server must have access to the client.
Access is granted by editing the /nsr/res/servers file.
Consider the following:
42
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server. To grant access to the NetWorker virtual server:
EMC NetWorker Release 8.0 Cluster Installation Guide
EMC AutoStart for UNIX Installation
1. On each node in the cluster:
a. Shut down the NetWorker services.
b. Edit or create the /nsr.Networker.local/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– For each virtual NetWorker server, add an entry for each physical host and the
virtual NetWorker server. For example:
clus_vir1
clus_phys1
clus_phys2
c. Check the NetWorker boot-time startup file to see whether nsrexecd is being run
with the -s option. If the -s option exists, remove all occurrences of the following in
the file:
-s server_name
2. On one node in the cluster, start the NetWorker service by using the cluster
management software:
a. Use the AutoStart Management Console to bring the NetWorker Resource Group
online.
b. Edit or create the /nsr/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– For each virtual NetWorker server, add an entry for each physical host and the
virtual NetWorker server. For example:
clus_vir1
clus_phys1
clus_phys2
3. If required, grant access to each NetWorker client that is outside of the cluster:
a. Shut down the NetWorker processes and verify that all NetWorker services have
stopped.
b. Edit or create the /nsr/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– For each virtual NetWorker server, add an entry for each physical host and the
virtual NetWorker server. For example:
clus_vir1

Task 5: Configure the NetWorker server
To configure the NetWorker server:
1. Log in as root on the cluster node that is currently running the NetWorker server
resource group.
2. Start the NetWorker Console software.
3. From the Administration window, select File>Properties.
a. For the Administrator attribute, add entries for any cluster nodes that are not
already listed. For example:
root@hostname
b. Click Ok.
Task 6: Configure clients under the NetWorker virtual server
When the networker.cluster script runs, it creates a symbolic link named /nsr that points
to a local disk. It also creates a second link points to the local NetWorker directory. For
example, if the local NetWorker directory was created in /var/nsr, each client member has
these links:
◆
AIX, HP-UX, Solaris
• /nsr->/nsr.NetWorker.local
• /nsr.NetWorker.local->/var/nsr
◆
Linux
• /nsr->/nsr.NetWorkerBackup.local
• /nsr.NetWorkerBackup.local->/var/nsr
To configure each client under the NetWorker server:
1. (Optional) Define savegroups.
In order for their save sets to restart after a virtual client or NetWorker server failover
savegroups must have the Autorestart attribute enabled and the Manual Restart
option disabled.
2. Make each physical client within the cluster a client of the NetWorker virtual server. For
each physical client in the cluster:
a. Create a new NetWorker client.
b. For the Name attribute, type the name of the physical client.
3. Make each virtual client within the cluster a client of the NetWorker virtual server. For
each virtual client in the cluster:
a. Create a new NetWorker client.
b. For the Name attribute, type the name of the virtual client.
44
EMC NetWorker Release 8.0 Cluster Installation Guide
EMC AutoStart for UNIX Installation
c. For the Remote Access attribute, add entries for each physical client within the
cluster. For example:
root@clus_phys1
d. For the Group attribute, select a group.
The first time the NetWorker application runs, it creates the Client resource for the
NetWorker virtual server. The EMC NetWorker 8.0 Administration Guide provides more
information.
4. For AIX only, on each node that the logical volume can be attached, check that the
/etc/filesystems file contains the same mount point for the logical volume as the one
specified in the FullTime AutoStart Resource group.
To change the entry for the logical volume mount point in the /etc/filesystems file,
type:
chfs -n new_mountpoint old_mountpoint
5. Run a test probe to verify that the Client and Group resources have been properly
configured.
Type this command on the node on which the NetWorker server resides:
savegrp -pv -c client_name group_name
The EMC NetWorker 8.0 Administration Guide provides information on what to do if
the test probe does not display the correct scheduled backups and index.
Task 7: Register NetWorker licenses for virtual server failover
To register a NetWorker server in a cluster environment:
1. Ensure that the NetWorker virtual server is defined as a part of the cluster.
2. Ensure that the NetWorker service is running.
3. For each physical node in the cluster, relocate, sequentially, the NetWorker server to
this node.
4. From the NetWorker Administration window, note the host ID number for the
appropriate cluster license.Log in to the system that is running the NetWorker virtual
server and create the /nsr/res/hostids file. This file contains the host IDs of all the
cluster nodes. Use this syntax:
hostid1:hostid2:hostid3:...
For example:
12345678:87654321
5. Restart the server by taking the NetWorker virtual server offline and then putting it
back online.
6. From the NetWorker Administration window, note the host ID number for the
appropriate cluster license.
7. Register the NetWorker software.

1. Open the AutoStart Console and select Resource Group. The Resource Group Editor
window appears.
2. Select Edit View and then select Attributes from the Edit menu. The Define Resource
Group Attributes dialog box appears.
3. Add the following line in the Define Resource Group Attributes window:
IPOverride=IP_address=raw_partition_path
For example: IPOverride=135.69.103.149=/dev/rdsk/c1t3d0s1
The IPOverride attribute does not add to the normal list of virtual client-owned paths, but
completely overrides them. In the previous example, if the virtual client also owns the
/share/web filesystem, set this path:
IPOverrride=135.69.103.149=/dev/rdsk/c1t3d0s1, /share/web

Software installation roadmap
Use the following roadmap to follow when installing NetWorker software:
1. Review “Installation requirements” on page 56 and note the default directory
locations.
2. Install the required NetWorker software by following one of these procedures:
• “Install a NetWorker virtual server” on page 58
• “Install only the NetWorker client software in a cluster” on page 64
3. Enable and register all of the NetWorker products. More information is available in the
NetWorker Licensing Guide.
Installation requirements
This section specifies the software and hardware required to install and configure the
NetWorker server or client software within an HACMP/PowerHA for AIX environment.
Software requirements
The EMC NetWorker Software Compatibility Guide on the EMC Online Support Site
provides information on the supported AIX and HACMP/PowerHA versions.
Hardware requirements
The following hardware requirements must be met:
◆
A dedicated shared volume group and file system used as the NetWorker storage area
(for the /nsr directory) must be connected to all the nodes within the cluster (for
server installation only).
◆
A device with local affinity for the local bootstrap backup connected to all the nodes
within the cluster (for server installation only).
◆
For clusters configured with IP address takeover (IPAT), must be connect to a computer
through its boot address if a resource group is not defined. Service addresses are
associated with a resource group, not physical nodes.
• The output of the hostname command on a machine must correspond to an IP
address that can be pinged.
• The machine hostname must also be set to the name equivalent to the address
that is used by the physical client’s dedicated NIC. Configure this NIC as the
primary network adapter, for example, en0.
• An extra NIC outside of the control of HACMP/PowerHA for AIX is not required to
enable a highly available NetWorker server.

HACMP or PowerHA SystemMirror for AIX Installation
Configuration options
The EMC NetWorker 8.0 Administration Guide provides details about the following
optional configurations:
◆
Tape libraries with a NetWorker virtual server
◆
Remote physical storage nodes with a NetWorker virtual server
System information requirements
Figure 3 on page 58 illustrates a sample cluster configuration and Table 16 on page 57
displays the system information needed to install NetWorker software within an
HACMP/PowerHA for AIX cluster environment.
These terms are used to define HACMP/PowerHA for AIX cluster concepts:
◆
Node name — The HACMP/PowerHA for AIX defined name for a physical node.
◆
Boot address — The address used by a node when it boots up, but before
HACMP/PowerHA for AIX starts.
◆
Service address — The address used by highly available services in an
HACMP/PowerHA for AIX environment.
◆
Virtual client — The client associated with a highly available resource group. The file
system defined in a resource group belongs to a virtual client. The virtual client uses
the service address.
The HACMP/PowerHA for AIX resource group must contain an IP service label to be
considered a NetWorker virtual client.
◆
Physical client — The client associated with a physical node. For example the / and
/usr file systems belong to the physical client.
◆
Physical host address (physical hostname) — The address used by the physical client.
For HACMP for AIX 4.5, this is equivalent to a persistent IP address.

Task 1: Install the NetWorker software in a cluster
To install the NetWorker software in a cluster:
1. Ensure that the most recent HACMP/PowerHA for AIX patch is installed.
2. Install these NetWorker software packages on each node in the cluster:
• Client
• Storage node
• Server
The NetWorker Installation Guide provides installation instructions.
Task 2: Define the server as highly available
To define and configure the NetWorker server as highly available:
1. Log in as root.
2. Ensure that the /etc/hosts file on each cluster node contains the name of the virtual
host. The virtual hostname in the DNS or NIS can be published.
3. From each node in the cluster that will run the NetWorker server process:
a. Run the cluster configuration script, networker.cluster, located in the /usr/bin/
directory.
b. Type the following information:
– Location of the local NetWorker database directory provided during the
installation procedure:
/nsr
– Published virtual hostname:
clus_vir1
– Shared nsr mount directory:
/nsr_shared_mnt_pt
Any configuration can be undone by running the networker.cluster -r option.
4. Verify that these values are set:
NSR_SERVERHOST = virtual hostname (clus_vir1)
NSR_SHARED_DISK_DIR = shared nsr mount directory
(/nsr_shared_mnt_pt)
Task 3: Define a NetWorker virtual server

Start script: /usr/bin/nw_hacmp.lc start
Stop script: /usr/bin/nw_hacmp.lc stop
This application server will be used by the NetWorker resource group.
4. Configure a NetWorker resource group.
The HACMP/PowerHA for AIX documentation provides instructions on defining and
monitoring a resource group in an HACMP/PowerHA for AIX environment.
Task 4: Grant access to the NetWorker virtual server
Before a NetWorker server can back up a client, the server must have access to the client.
Granting access to the server is controlled by editing the /nsr/res/servers file.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To grant access to the NetWorker virtual server:
1. Perform the following on each node in the cluster:
a. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped.
b. Edit or create the /nsr.NetWorker.local/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– For each virtual NetWorker server, add an entry for each physical host and the
NetWorker virtual server. For example:
clus_vir1
clus_phys1
clus_phys2
60
EMC NetWorker Release 8.0 Cluster Installation Guide
HACMP or PowerHA SystemMirror for AIX Installation
c. Check the NetWorker boot-time startup file to see whether nsrexecd is being run
with the -s option. If the -s option exists, remove all occurrences of this in the file:
-s server_name
2. Perform the following on one node in the cluster, start the NetWorker service by using
the cluster management software:
a. Use the HACMP/PowerHA for AIX software to bring the NetWorker resource group
online.
b. Edit or create the /nsr/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to the client.
– For each virtual NetWorker server, add an entry for each physical host and the
virtual NetWorker server. For example:
clus_vir1
clus_phys1
clus_phys2
3. If required, grant access to each NetWorker client that is outside of the cluster:
a. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped:
nsr_shutdown
ps -ef | grep nsr
b. Edit or create the /nsr/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to the client.
– For each virtual NetWorker server, add an entry for each physical host and the
virtual NetWorker server. For example:
clus_vir1
clus_phys1
clus_phys2
Task 5: Configure the NetWorker cluster server
To configure the NetWorker server:
1. Log in as root on the cluster node that is running the NetWorker virtual server.
2. Start the NetWorker Console software.
a. From the Console window, click Enterprise.
b. From the left pane, select the Enterprise icon.
The NetWorker server appears in the right and left panes.

3. From the Administration window, click Configuration:
a. In the left pane, select the NetWorker server.
b. From the File menu, select Properties. The Properties dialog box appears:
– For the Administrator attribute, add entries for any cluster nodes that are not
already listed. For example:
root@hostname
– Click Ok.
Task 6: Configure clients under the NetWorker cluster server
When the networker.cluster script runs, it creates a symbolic link named /nsr that points
to a local disk. It also creates a second link named nsr.NetWorker.local that points to the
local NetWorker directory. For example, if the local NetWorker directory was created in
/var/nsr, each client member has these links:
◆
/nsr->/nsr.NetWorker.local
◆
/nsr.NetWorker.local->/var/nsr
To configure clients under the NetWorker cluster server:
1. (Optional) Define savegroups.
In order for their save sets to restart after a virtual client or NetWorker server failover,
savegroups must have the Autorestart attribute enabled and the Manual Restart
option disabled.
2. Make each physical client within the cluster a client of the NetWorker server. For each
physical client in the cluster:
a. Create a new NetWorker client.
b. Type the name of the physical client for the Name attribute.
c. Add the boot adaptor name in the Aliases list.
3. Make each virtual client within the cluster a client of the virtual NetWorker server. For
each virtual client in the cluster:
a. Create a new client.
b. Type the name of the service address for the Name attribute.
c. For the Remote Access attribute, the user must be the root user for the boot
address.
d. Add entries for each service, boot, and physical address defined within the cluster.
For example:
root@clus_phys1
e. For the Group attribute, select a group.
62

4. Run a test probe to verify that the Client and Group resources have been properly
configured.
On the node on which the NetWorker server resides, type:
savegrp -pv -c client_name group_name
5. If the test probe does not display the scheduled backups and index, see “Track
scheduled saves” on page 68.
Task 7: Register NetWorker licenses for virtual server failover
To register a NetWorker server in a cluster environment:
1. Ensure that the NetWorker virtual server is defined as a part of the cluster.
2. Ensure that the NetWorker service is running.
3. For each physical node in the cluster:
a. Relocate, sequentially, the NetWorker server to this node.
b. From the NetWorker Administration window, note the host ID number for the
appropriate cluster license.
4. Log in to the system that is running the NetWorker virtual server and create the
/nsr/res/hostids file. This file contains the host IDs of all the cluster nodes.
Use this syntax:
hostid1:hostid2:hostid3:...
For example:
12345678:87654321
5. Restart the server by taking the NetWorker virtual server offline and then putting it
back online.
6. From the NetWorker Administration window, note the host ID number for the
appropriate cluster license.

Task 3: Define the list of trusted NetWorker servers
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the /nsr/res/servers file.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To define the list of trusted NetWorker servers, perform these steps on each node in the
cluster:
1. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped.
2. Edit or create the /nsr/res/servers file:
a. Add the set of NetWorker servers, one per line, that require access to this client.
b. For each NetWorker virtual server, add an entry for each physical host and the
NetWorker virtual server. For example:
clus_vir1
clus_phys1
clus_phys2
3. Check the NetWorker boot-time startup file to see whether nsrexecd is being run with
the -s option. If the -s option exists, remove all occurrences of this in the file:
-s server_name
Task 4: Configure clients under the NetWorker server
To configure the NetWorker server:
1. Make each physical client within the cluster a client of the NetWorker server.
For each physical client in the cluster:
a. Create a new client.
b. Type the name of the physical client for the Name attribute.
c. Add the boot adaptor name in the Aliases list.
If a physical Client is backed up to a NetWorker server outside the cluster, the name of
any virtual service that can run on the physical node must be added to the Remote
Access list of the physical Client property sheet.

Configure an external client to a virtual server
If required, use this procedure to configure and back up an external client to a NetWorker
virtual server.
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the /nsr/res/servers file.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
On each NetWorker client that is outside of the cluster:
1. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped.
2. Edit or create the /nsr/res/servers file:
a. Add the set of NetWorker servers, one per line, that require access to this client.
b. For each virtual NetWorker server, add an entry for each physical host and the
virtual NetWorker server. For example:
clus_vir1
clus_phys1
clus_phys2
Configure an external client to a virtual server
67
HACMP or PowerHA SystemMirror for AIX Installation
Schedule saves for raw volumes
To enable NetWorker scheduled saves of raw volumes that are owned by a resource group
(virtual client), flag the logical volume as follows:
1. Ensure that the volume group to which the logical volume belongs appears under
Volume Groups in the resource group configuration.
2. Set the logical volume type to raw by using the chlv command. For example:
chlv -t 'raw' logical_volume_name
In this example, the logical volume ha_rv, that belongs to the volume group havg, will
be used as a raw device:
chlv -t’raw’ ha_rv
lsvg -l havg
havg:
The NetWorker software does not support raw volumes used for concurrent access.
Track scheduled saves
To verify that the Client and Group resources are properly configured, run a test probe for
each client from the node where the NetWorker application is running:
savegrp -pv -c client_name group_name
If the test probe does not display all the scheduled save sets:
◆
Check the cluster configuration by using the cluster management software. If
necessary, reconfigure the cluster.
◆
Ensure that the save sets defined for the client are owned by that client. If necessary,
redistribute the client save sets to the appropriate Client resources.
Misconfiguration of the Cluster resources might cause scheduled save sets to be
dropped from the backup. The EMC NetWorker 8.0 Administration Guide provides
more information.
◆
Type this command to override scheduled save rules (not path ownership rules):
touch networker_bin_dir/pathownerignore
◆
Run a second test probe to verify the configuration.
This command allows any path to be backed up for a client, whether it is owned by the
virtual client or physical node. The EMC NetWorker 8.0 Administration Guide provides
more information.
68
EMC NetWorker Release 8.0 Cluster Installation Guide
HACMP or PowerHA SystemMirror for AIX Installation
If the pathownerignore command was used, check that the NetWorker scheduled save
uses the correct client index. If the wrong index is used, the save sets can be forced to go
to the correct index:
1. From the NetWorker Administration window, select a client and edit its properties.
2. For the Backup Command attribute, type the name of a backup script that contains
save -c client_name,
The NetWorker administration guide provides details on the Backup Command
attribute.

Different operating systems use different terms for the same cluster concepts. For
example, HP-UX MC/ServiceGuard and HP-UX MC/LockManager refer to:
◆
Physical hosts as nodes
◆
Virtual server as a package
Prepare the system for the NetWorker installation
Before installing the NetWorker software, review the following sections in the HP-UX
Installation chapter of the NetWorker 8.0 Installation Guide:
◆
Unzip and extract the NetWorker package- for package download and extraction
details.
◆
Consider the installation directory - for details regarding the installation of the
NetWorker software to a non default location and disk space requirements.
Install the NetWorker server as highly available on HP-UX
MC/ServiceGuard
Use this roadmap to install and configure the NetWorker software as a highly available
application in a cluster:
◆
“Task 1: Install the NetWorker server software” on page 74
◆
“Task 2: Configure the NetWorker software” on page 75
◆
“Task 4: Change the NetWorker servers with access to a client” on page 79
◆
“Task 5: Make the cluster nodes a client of the NetWorker virtual server” on page 80
◆
“Task 6: Register NetWorker licenses for cluster server failover” on page 80
Task 1: Install the NetWorker server software
The NetWorker server software must be installed on all nodes in the cluster to provide
failover support. Refer to the section Installing NetWorker on HP-UX in the NetWorker 8.0
Installation Guide for the installation steps.
Consider the following:
74
◆
Ensure that the /etc/hosts file on each cluster node contains the name of the virtual
host. The virtual hostname can be published in the Domain Name System (DNS) or
Network Information Services (NIS).
◆
The cluster services do not automatically start after a reboot. Set the
AUTOSTART_CMCLD=1 value in the /etc/rc.config.d/cmcluster file to configure the
cluster services to automatically start. If the value is set to 0, the cluster services do
not automatically start after a reboot. Setting the value to 1 ensures that the cluster
services start after reboot.
EMC NetWorker Release 8.0 Cluster Installation Guide
MC/ServiceGuard and MC/LockManager Installation
◆
When the NetWorker software is configured for the cluster on a node, the cluster
configuration creates:
• A symbolic link, /nsr.NetWorker.local, that points to the directory that contains the
NetWorker configuration files.
• A link, /nsr, that points to the /nsr.NetWorker.local.
For example, if the local NetWorker directory was created in /var/nsr, each client
member has the following links after the installation:
• /nsr->/nsr.NetWorker.local
• /nsr.NetWorker.local->/var/nsr
Task 2: Configure the NetWorker software
NetWorker 8.0 and later introduces a new method to configure the NetWorker software in a
MC/ServiceGuard environment.
This new method has the following benefits:
◆
Support of multiple IPs in one package. Refer to the “Support for multiple IP addresses
for one resource group” in the NetWorker 8.0 Administration Guide for more
information.
◆
Support for the lcmap caching mechanism. Refer to the “NetWorker cluster
performance issues” section in the NetWorker 8.0 Administration Guide for
information about adjusting the cluster cache timeout value.
◆
Does not require the creation and configuration of the NetWorker.clucheck and
.nsr_cluster files.
If desired, the previous method to configure the NetWorker software using the
NetWorker.clucheck and .nsr_cluster files can still used.
Install the NetWorker server as highly available on HP-UX MC/ServiceGuard
75
MC/ServiceGuard and MC/LockManager Installation
To configure the NetWorker software:
If the previous method of configuring the NetWorker sever as highly available will be used,
create the NetWorker.clucheck file and configure the .nsr_cluster file as detailed in Step 1
and 2. If the new method of configuring the NetWorker server will be used, proceed to
step .
1. Create the NetWorker.clucheck file in the /etc/cmcluster directory.
2. Configure the .nsr_cluster file in the /etc/cmcluster directory to determine which
mount points an MC/ServiceGuard or MC/LockManager package owns. The
.nsr_cluster file should have an entry for the NetWorker shared mount point, which is
owned by the NetWorker package.
a. Add the name and path of each mount point to the file in the following format:
pkgname:published_ip_address:owned_path [:...]
where published_ip_address is the address assigned to the package owning a
shared disk. IPv6 addresses must be enclosed in square brackets, as in the
following example:
networker:[3ffe:80c0:22c:74:230:6eff:fe4c:2128]:/share/nw
IPv4 addresses can also be enclosed in square brackets, but it is not necessary.
b. Ensure everyone has read ownership and access permissions for the .nsr_cluster
file.
c. Additional paths, preceded by colons, can be added as required. The following is
an example of a typical .nsr_cluster file:
networker:192.168.109.41:/vg011
oracle:192.168.109.10:/vg021:/ora_data1:/ora_data2
If an HP-UX MC/ServiceGuard package does not contain a disk resource, it does
not require an entry in the .nsr_cluster file. However, if this diskless package is
online and the only package on that cluster node, there might be cmgetconf
messages generated in the var/admin message file during the backup.
To avoid these messages, allocate a file system that is mounted to a mount point
and add this mount point along with the package name and IP address into the
.nsr_cluster file in the format shown above. This file system is not backed up, but
should be mountable on each cluster node that the diskless package might fail
over to.
Task 3: Define the NetWorker software as highly available
Define the NetWorker software as highly available in one of two modes:
◆
“Legacy Mode” on page 77
◆
“Modular mode” on page 78
Use the Logical Volume Manager (LVM) to define the logical volumes or volume groups the
NetWorker software will use. The HP-UX documentation provides more information.

The networker.cluster script creates a pkg.conf file and a legato.control file on the
physical host on which it is running.
3. Copy the legato.control file to all the nodes in the cluster and ensure that execute
permissions are set.
4. After the legato.control file is copied to all the nodes in the cluster, run the
networker.cluster script on the remaining nodes in the cluster. When prompted to
generate a legato.control file, type n.
5. Check each node to determine if the nsrexecd daemon is running:
ps -ef | grep nsrexecd
6. Check each node to determine if the legato.control file was successfully installed on
each node:
cd /etc/cmcluster/networker
more legato.control
7. On the node on which the networker.cluster script was initially run:
• Determine if the pkg.conf file was installed correctly:
cd /etc/cmcluster/networker
cmcheckconf -P pkg.conf
cmapplyconf -P pkg.conf

Task 4: Change the NetWorker servers with access to a client
In a cluster, the NetWorker server software on the active node accesses the global /nsr
directory on the shared drive. The passive node will also have the NetWorker server
software installed but the node will act as a NetWorker client.
To limit the NetWorker servers authorized to access the cluster nodes, the global
/nsr/res/servers file on the shared drive must be modified as well as the /nsr/res/servers
file in the local /nsr directory on all passive nodes.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To specify a list of NetWorker servers that can access the cluster:
1. Use the cluster management software to shutdown the NetWorker service on one node
in the cluster.
2. On each node in the cluster:
a. Edit or create the local /nsr/res/servers file and specify the NetWorker servers, one
per line, that require access to the client. Ensure that the first entry in this file is the
virtual hostname for the NetWorker service. This entry becomes the default
NetWorker server.
b. Check the NetWorker boot-time startup file for nsrexecd -s arguments and delete
any that exist. The nsrexecd -s argument supersedes the /nsr/res/servers file.
For example, delete the arguments for nsrexecd -s in the following file:
vi /etc/init.d/networker
nsrexecd -s venus -s mars
The nsrexecd daemon named in the file should appear only as:
nsrexecd
3. On one node in the cluster, start the NetWorker service by using the cluster
management software.
4. Repeat steps 2-3 for the global /nsr/res/servers file located shared drive on the active
node of the cluster.
Install the NetWorker server as highly available on HP-UX MC/ServiceGuard
79
MC/ServiceGuard and MC/LockManager Installation
Task 5: Make the cluster nodes a client of the NetWorker virtual server
Make all cluster nodes a client of the NetWorker server:
1. While still connect to the NetWorker server in NMC.
2. Configure the Group resource to be used to backup the cluster clients, as required.
Enable the Autorestart attribute is enabled and the Manual Restart option disabled.
This will ensure that save set backups will restart in the event of a virtual client of
NetWorker server failover during backups. The NetWorker 8.0 Administration Guide
provides details on defining and configuring groups.
3. Create a new NetWorker client for each physical node within the cluster:
a. In the Administration window, click the Configuration button.
b. Create a new NetWorker client.
c. In the Name attribute, type the name of the physical client.
4. Modify the virtual cluster client resource automatically created for the virtual
NetWorker server:
a. In the Save set field, specify the shared disk resource.
b. In the Remote Access field under the Globals (1 of 2) tab, specify the root user
account for each physical node within the cluster.
For example:
root@<clus_phys1>
root@<clus_phys2>
c. In the Group attribute, select the Group configured in step 2 .
d. Define the remaining attributes in the Client properties window as required, then
click Apply.
5. Run a test probe to verify that the Client and group resources have been properly
configured:
a. On the node on which the NetWorker server resides, run this command:
savegrp -pv -c <client_name> -G <group_name>
b. If the test probe does not display the scheduled backups and index, see “Track
scheduled saves” on page 89 for more information.
Task 6: Register NetWorker licenses for cluster server failover
To register a NetWorker server in a cluster environment:
1. Ensure that the NetWorker virtual server is defined as a part of the cluster.
2. Ensure that the NetWorker service is running.
3. For each physical node in the cluster:
a. Relocate, sequentially, the NetWorker server to this node.
b. From the NetWorker Administration window, note the host ID number for the
appropriate cluster license.
80
EMC NetWorker Release 8.0 Cluster Installation Guide
MC/ServiceGuard and MC/LockManager Installation
4. Log in to the system that is running the NetWorker virtual server and create a file
named /nsr/res/hostids that contains the host IDs of all the cluster nodes.
Use the following syntax:
hostid1:hostid2:hostid3:...
For example:
12345678:87654321
5. Restart the server by taking the NetWorker virtual server offline and then putting it
back online.
6. From the NetWorker Administration window, note the host ID number for the
appropriate cluster license.
7. Register the NetWorker software as described in the NetWorker Licensing Guide.
VxVM on HP ServiceGuard clusters
The NetWorker cluster scripts have been modified to support VxVM on HP ServiceGuard
clusters. The following procedure outlines how to set up the VxVM file system on the
physical nodes in the cluster.
In all examples, the physical nodes in the cluster are dbkpsr01 and dbkpsr02.
1. Mount the VxVM file system as /nsrdata on the dbkpsr01 node (active node) by
running the following:
mount /dev/vx/dsk/nsrdg/nsrvol /nsrdata
Do not use /nsr as the mount point.
2. Install the NetWorker server software on both nodes. This will install the software in
the /opt/NetWorker/bin directory.
3. Create the /NetWorker.clucheck/etc/cmcluster directory on dbkpsr01 by running:
touch NetWorker.clucheck
4. Create the /NetWorker.clucheck/etc/cmcluster directory on dbkpsr02 by running:
touch NetWorker.clucheck
5. On dbkpsr01, create .nsr_cluster in the /etc/cmcluster directory with the following
text:
networker:10.2.6.12:/nsrdata
6. On dbkpsr01, run:
rcp -r -p /etc/cmcluster/.nsr_cluster dbkpsr02:/etc/cmcluster
7. Run networker.cluster on dbkpsr01.

◆
“Task 2: Configure the NetWorker client software in the cluster” on page 85
◆
“Task 3: Change the NetWorker servers with access to a client” on page 86
◆
“Task 4: Configure cluster clients on the NetWorker server” on page 87
Task 1: Install the NetWorker software
The NetWorker client software must be installed on all nodes in the cluster. Refer to the
section Installing NetWorker on HP-UX in the NetWorker 8.0 Installation Guide for the
installation steps.

Task 2: Configure the NetWorker client software in the cluster
NetWorker 8.0 and later introduces a new method to configure the NetWorker software in a
MC/ServiceGuard environment.
This new method has the following benefits:
◆
Support of multiple IPs in one package
◆
Support for the lcmap caching mechanism
◆
Does not require the creation and configuration of the NetWorker.clucheck and
.nsr_cluster files.
If desired, the previous method to configure the NetWorker software using the
NetWorker.clucheck and .nsr_cluster files can still used.
To configure the NetWorker client software in the cluster:
If the previous method of configuring the NetWorker client in a cluster will be used, create
the NetWorker.clucheck file and configure the .nsr_cluster file as detailed in Step 1 and 2.
If the new method of configuring the NetWorker server will be used, proceed to step 3 .
1. Create the NetWorker.clucheck file in the /etc/cmcluster directory.
2. Configure the .nsr_cluster file in the /etc/cmcluster directory to determine which
mount points an MC/ServiceGuard or MC/LockManager package owns. The
.nsr_cluster file should have an entry for the NetWorker shared mount point, which is
owned by the NetWorker package.
a. Add the name and path of each mount point to the file in the following format:
pkgname:published_ip_address:owned_path [:...]
where published_ip_address is the address assigned to the package owning a
shared disk. IPv6 addresses must be enclosed in square brackets, as in the
following example:
networker:[3ffe:80c0:22c:74:230:6eff:fe4c:2128]:/share/nw
IPv4 addresses can also be enclosed in square brackets, but it is not necessary.
b. Ensure everyone has read ownership and access permissions for the .nsr_cluster
file.
c. Additional paths, preceded by colons, can be added as required. The following is
an example of a typical .nsr_cluster file:
networker:192.168.109.41:/vg011
oracle:192.168.109.10:/vg021:/ora_data1:/ora_data2
If an HP-UX MC/ServiceGuard package does not contain a disk resource, it does
not require an entry in the .nsr_cluster file. However, if this diskless package is
online and the only package on that cluster node, there might be cmgetconf
messages generated in the var/admin message file during the backup.
To avoid these messages, allocate a file system that is mounted to a mount point
and add this mount point along with the package name and IP address into the

.nsr_cluster file in the format shown above. This file system is not backed up, but
should be mountable on each cluster node that the diskless package might fail
over to.
3. Configure the NetWorker client software as cluster aware:
a. Run the networker.cluster script (located in the /opt/networker/bin directory) on
one of the nodes where the NetWorker software is installed.
b. Follow the prompts to configure the NetWorker package in Modular mode:
a. Do you wish to continue? [Yes]? Press Enter.
b. Enter directory where local NetWorker database is installed [/nsr]? Press Enter.
c. Do you wish to use the updated NetWorker integration framework? Yes or No
[Yes]?
– If the previous method to configure the NetWorker software using the
NetWorker.clucheck and .nsr_cluster files was performed, enter No at this
prompt.
– If the updated method will be used to configure the NetWorker software (Steps
1 and 2) were not performed, enter Yes at this prompt.
d. Do you wish to configure for both NetWorker server and client? Yes or No [Yes]?
Enter No.
Task 3: Change the NetWorker servers with access to a client
On each node in the cluster, modify the /nsr/res/servers file to limit the NetWorker servers
authorized to access the NetWorker client.
Consider the following:
86
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
EMC NetWorker Release 8.0 Cluster Installation Guide
MC/ServiceGuard and MC/LockManager Installation
To specify a list of NetWorker servers that can access the cluster, on each node in the
cluster:
a. Edit or create the local /nsr/res/servers file and specify the NetWorker servers, one
per line, that require access to the client. The first entry becomes the default
NetWorker server.
b. Check the NetWorker boot-time startup file for nsrexecd -s arguments and delete
any that exist. The nsrexecd -s argument supersedes the /nsr/res/servers file.
For example, delete the arguments for nsrexecd -s in the following file:
vi /etc/init.d/networker
nsrexecd -s venus -s mars
The nsrexecd daemon named in the file should appear only as:
nsrexecd
c. Use the NetWorker boot-time startup file to stop and restart the NetWorker
software, as follows:
/sbin/init.d/networker stop
/sbin/init.d/networker start
Task 4: Configure cluster clients on the NetWorker server
To make the cluster node a client of the NetWorker server:
1. Login to the NetWorker Management console as an administrator and connect to the
NetWorker server.
2. Create a new NetWorker client for each physical node within the cluster:
a. In the Administration window, click the Configuration button.
b. Create a new NetWorker client.
c. In the Name attribute, type the name of the physical client.
3. Create a new NetWorker client for each virtual host within the cluster:
a. Create a new NetWorker client.
b. In the Name field, type the name of the virtual client.
c. In the Save set field, specify the shared disk resource.
d. In the Remote Access field under the Globals (1 of 2) tab, specify the root user
account for each physical node within the cluster.
For example:
root@<clus_phys1>
root@<clus_phys2>
e. In the Group attribute, select a group.
f. Define the remaining attributes in the Client properties window as required, then
click Apply.
Install only the NetWorker client software in a cluster

4. Run a test probe to verify that the Client and resources have been properly configured.
On the node on which the NetWorker server resides, run this command:
savegrp -pv -c <client_name> -G <_name>
If the test probe does not display the scheduled backups and index, see “Track
scheduled saves” on page 89 for more information.
Uninstall the NetWorker software
To remove the NetWorker software from a cluster environment:
1. Halt the NetWorker package:
cmhaltpkg networker
2. Shut down the client services on each node from which the NetWorker software is
being removed:
nsr_shutdown
3. To keep the NetWorker server software in the cluster:
a. Migrate it to another node in the cluster, type:
cmrunpkg -n clus_phys1 -v networker
b. Run this command:
/opt/networker/bin/networker.cluster -r
c. If the previous method was used to install the NetWorker software, remove the
following file from the /etc/cmcluster directory:
NetWorker.clucheck
4. To avoid running the NetWorker server software in the cluster, remove the NetWorker
package software. The EMC NetWorker Installation Guide provides information on how
to uninstall the software.

Track scheduled saves
To verify that the Client and resources are properly configured, run a test probe for each
client from the node where the NetWorker application is running:
savegrp -pv -c client_name _name
If the test probe does not display all the scheduled save sets:
◆
Check the cluster configuration by using the cluster management software. If
necessary, reconfigure the cluster.
◆
Ensure that the save sets defined for the client are owned by that client. If necessary,
redistribute the client save sets to the appropriate Client resources.
Misconfiguration of the Cluster resources might cause scheduled save sets to be
dropped from the backup. The EMC NetWorker administration guide provides more
information.
◆
Type this command to override scheduled save rules (not path ownership rules):
touch networker_bin_dir/pathownerignore
◆
Run a second test probe to verify the configuration.
This command allows any path to be backed up for a client, whether it is owned by the
virtual client or physical node. The EMC NetWorker administration guide provides
more information.
If the pathownerignore command was used, check that the NetWorker scheduled save
uses the correct client index. If the wrong index is used, the save sets can be forced to go
to the correct index:
1. From the NetWorker Administration window, select a client and edit its properties.
2. For the Backup Command attribute, type the name of a backup script that contains
save -c client_name.
The NetWorker administration guide provides details about the Backup Command
attribute.

Microsoft Cluster Server (MSCS) Installation
Installation requirements
In NetWorker 8.0 and later, only the NetWorker client software supports MSCS. This
section specifies the software and hardware required to install and configure the client
software within a MSCS environment. Consider the following:
◆
The MSCS software must be installed in a Microsoft certified hardware configuration.
◆
NetWorker software must always be installed on the private disk of a node.
Install only the NetWorker client software in a cluster
To install the NetWorker client software as cluster-aware:
1. Install the NetWorker client software on the private disk of each node in the cluster.
2. Configure each node in the cluster as a client of the NetWorker server. These are
physical cluster clients.
If the NetWorker server is configured as a Cluster resource, add the hostname and user
of this NetWorker virtual server to these Client resource attributes of the physical
cluster clients:
• Remote Access
• Administrator
3. Configure each of the virtual servers in a cluster as a client of the NetWorker virtual
server. These are virtual cluster clients.
4. Add the hostname and user of each node to these Client resource attributes of the
virtual clients:
• Remote Access
• Administrator
5. If the NetWorker Remote Exec service is started before the cluster service is enabled
on the node, restart the NetWorker Remote Exec service on each cluster node.
Uninstall the NetWorker software from MSCS
If the NetWorker server is configured as a cluster resource, perform the following steps
before removing the NetWorker software.
If the NetWorker server is installed as a stand-alone application (not cluster managed) or
only the client software is installed, follow the standard uninstall procedure for NetWorker
software. The NetWorker Installation Guide provides instructions on how to uninstall the
software.

Microsoft Failover Cluster on Windows Server 2008
5. Restrict the set of NetWorker servers that can back up a particular client. Edit the
%SystemDrive%\Program Files\EMC NetWorker\nsr\res\servers file and add the
NetWorker virtual host as well as each cluster node to the list of servers.
Consider the following:
• If no servers are specified, any NetWorker server can backup this client.
• If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
• When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
Task 9: Configure clients on the NetWorker virtual server
To configure the NetWorker Client resource:
1. On each physical node, ensure that the following file contains the names of virtual
hosts:
%SystemRoot%\system32\drivers\etc\hosts
2. Start the NetWorker Management Console software.
3. Make each physical node within the cluster a client of the NetWorker virtual server.
For each physical node in the cluster:
a. Create a new Client resource.
b. For the Name attribute, type the name of the physical host.
TheNetWorker administration guide details how to create a Client resource.
4. Make each virtual node within the cluster a client of the NetWorker virtual server.
For each virtual node in the cluster:
a. Create a new Client resource.
b. For the Name attribute, type the name of the virtual host.
c. For the Remote Access attribute, type the user@hostname of each physical node
within the cluster.
5. To back up a NetWorker Windows client that has multiple domains that are part of
both an Active Directory domain, and a DNS domain, perform one of the following
steps:
• Define the Active Directory domain name, which is the Full Computer Name, in the
NetWorker server’s hosts file.
• Define the AD domain, which is the Full Computer Name, in the Active Directory
DNS. Also, on the NetWorker server, open the Client resource and add the Full
Computer Name in the alias list.
6. Define one or more NetWorker Group resources to include the virtual hosts and each
of the physical nodes in the cluster:
a. Create the necessary groups and define their attributes as appropriate.
b. For each group, select Enabled for the Autorestart attribute.
Install the NetWorker software in a Microsoft Failover Cluster
115
Microsoft Failover Cluster on Windows Server 2008
c. For each group, ensure that Manual Restart is not selected in the Options attribute
(under the Advanced tab).
The only save sets that restart after a virtual server failover are those that belong to a
group in which Autorestart is enabled and Manual Restart is disabled.
After the client configuration is complete:
◆
The NetWorker virtual server uses the IP address of the NetWorker virtual host,
regardless of which cluster node currently masters the NetWorker virtual server.
◆
The NetWorker virtual server takes the identity of the NetWorker virtual server’s
hostname, regardless of which cluster node is currently running the NetWorker
service.
◆
The first time NetWorker server runs, it creates the Client resource for the NetWorker
virtual host. Client resources must be created manually for any cluster node that is to
be backed up by the NetWorker virtual server.
Task 10: Verify that the Client and Group resources have been configured
To verify that the Client and Group resources are properly configured, run a test probe for
each client from the node where the NetWorker application is running:
savegrp -pv -c client_name group_name
If the test probe does not display all the scheduled save sets:
◆
Check the cluster configuration by using the cluster management software. If
necessary, reconfigure the cluster.
◆
Ensure that the save sets defined for the client are owned by that client. If necessary,
redistribute the client save sets to the appropriate Client resources.
Misconfiguration of the Cluster resources might cause scheduled save sets to be
dropped from the backup. The NetWorker administration guide provides more
information.
◆
To override scheduled save rules, create an empty text file, pathownerignore in the
directory that contains the savefs command. By default the NetWorker bin location is
C:\Program Files\EMC NetWorker\nsr\bin.
When this file exists, it allows any path to be backed up for a client, whether it is
owned by the virtual client or physical node. The NetWorker 8.0 Administration Guide
provides more information.
◆
Run a second test probe to verify the configuration.
If the pathownerignore file was used, check that the NetWorker scheduled save uses the
correct client index.
116
EMC NetWorker Release 8.0 Cluster Installation Guide
Microsoft Failover Cluster on Windows Server 2008
If the wrong index is used, the save sets can be forced to go to the correct index:
1. From the NetWorker Administration window, select a client and edit its properties.
2. For the Backup Command attribute, type the name of a backup script that contains:
save -c client_name
The NetWorker 8.0 Administration Guide provides details about the Backup Command
attribute.
Install only the NetWorker client software
In this configuration, the NetWorker server is running on a node that is not a member of
the cluster.
To install NetWorker client on the cluster node, follow the procedures for these tasks:
◆
“Task 1: Install the NetWorker client software” on page 117
◆
“Task 2: Define the list of trusted NetWorker servers” on page 117
◆
“Task 3: Configure clients under the NetWorker server” on page 118
◆
“Task 4: Verify that the Client and Group resources have been configured” on
page 118
Ensure the NetWorker client software is installed on every physical node in the cluster to
be backed up.
Task 1: Install the NetWorker client software
To install the NetWorker client software on each node in the cluster:
1. Ensure that the operating system is updated with the most recent cluster patch.
2. Install the NetWorker client software on the physical disk of each node in the cluster to
be backed up.
Task 2: Define the list of trusted NetWorker servers
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the servers file.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To define the list of trusted NetWorker servers, perform the following steps on each node
in the cluster:
1. Edit or create the %SystemDrive%\Program Files\EMC NetWorker\nsr\res\servers file.
2. Add the NetWorker servers, one per line, that require access to this client.
Install the NetWorker software in a Microsoft Failover Cluster
117
Microsoft Failover Cluster on Windows Server 2008
Task 3: Configure clients under the NetWorker server
To configure the NetWorker server:
1. (Optional) Define save groups.
2. Make each physical Client within the cluster a client of the NetWorker server.
For each physical client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the physical client.
3. Make each virtual client within the cluster a client of the NetWorker server for each
virtual client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the virtual client.
c. For the Remote Access attribute, enter the user@hostname of each physical node
within the cluster.
d. For the Group attribute, select a group.
The first time the NetWorker application runs, it creates the Client resource for the
NetWorker virtual server.
4. To back up a NetWorker Windows client that has multiple domains that are part of
both an Active Directory domain and a DNS domain, perform one of these steps:
• Define the Active Directory domain name, which is the Full Computer Name, in the
NetWorker server’s /etc/hosts file.
• Define the AD domain, which is the Full Computer Name, in the Active Directory
DNS. Also, on the NetWorker server, open the Client resource and add the Full
Computer Name in the alias list.
5. If the NetWorker Remote Exec service is started before the cluster service is enabled
on the node, restart the NetWorker Remote Exec service on each cluster node.
6. Schedule backups by using the NetWorker application.
Task 4: Verify that the Client and Group resources have been configured
To verify that the Client and Group resources on the NetWorker server are properly
configured, run a test probe for each client from the node where the NetWorker server is
running:
savegrp -pv -c <client_name> <group_name>
If the test probe does not display all the scheduled save sets:
118
◆
Check the cluster configuration by using the cluster management software. If
necessary, reconfigure the cluster.
◆
Ensure that the save sets defined for the client are owned by that client. If necessary,
redistribute the client save sets to the appropriate Client resources.

Misconfiguration of the Cluster resources might cause scheduled save sets to be
dropped from the backup. The NetWorker administration guide provides more
information.
◆
Type this command to override scheduled save rules:
echo NUL: NetWorker_bin_dir\pathownerignore
This command allows any path to be backed up for a client, whether it is owned by the
virtual client or physical node. The NetWorker administration guide provides more
information.
◆
Run a second test probe to verify the configuration.
If the pathownerignore file was used, check that the NetWorker scheduled save uses the
correct client index. If the wrong index is used, the save sets can be forced to go to the
correct index:
1. From the NetWorker Administration window, select a client and edit its properties.
2. For the Backup Command attribute, type the name of a backup script that contains:
save -c client_name
The NetWorker 8.0 Administration Guide provides details about the Backup Command
attribute.
Uninstall the NetWorker software in a Microsoft Failover Cluster
If the NetWorker server is configured as a cluster resource, perform the following steps
before removing the NetWorker software. If the NetWorker server is installed as a

Update from a previous release of the software
To update the NetWorker software from a previous release:
1. Use the scrgadm and scconf commands to provide details about the current cluster
configuration and save the output to a file:
clrs show -v >clrs_v.out
clrg show -v >clrg_v.out
cluster show -v >cluster_v.out
2. If the NetWorker server is configured in a Sun Cluster, determine the location of the
NetWorker server global /nsr directory on the shared storage.
For example, on cluster_node1 the global /nsr directory is /global/nw/nsr:
cluster_node1: ls -l /nsr
lrwxrwxrwx
1 root root 14 May 30 15:06 /nsr -> /global/nw/nsr
3. If the target machine is a NetWorker server, perform a bootstrap and index backup.
For example:
savegrp -vvv -O group
The specified group contains all of the NetWorker clients in the datazone. This ensures
that all client file indexes are backed up.
If a group that contains all of the clients does not exist, run the savegrp command
more than once, specifying a different group each time, until all clients indexes are
backed up.
Ensure the media pool associated with the group has appendable media available.
4. Remove the NetWorker software cluster configuration files and uninstall the NetWorker
software. Do not remove the global and local /nsr directories.
“Uninstall the NetWorker software” on page 148 provides instructions for uninstalling
the NetWorker software.
5. If required, upgrade the Sun Cluster software. For instructions, refer to the Sun Cluster
documentation.

Sun Cluster Version 3.2 Installation
Task 1: Install the NetWorker software
The NetWorker software must be installed on all nodes in the cluster that are required to
run the NetWorker resource group.
Ensure that the following apply:
- The operating environment and Sun Cluster 3.2 software are already installed on all
nodes in the cluster and that those nodes boot in cluster mode.
- PATH environment variable includes /usr/sbin and /usr/cluster/bin.
To install the NetWorker software on nodes that will be running the NetWorker resource
group:
1. Access the NetWorker software from the distribution media. The NetWorker
Installation Guide provides installation instructions.
2. Keep a copy of the current configuration. The NetWorker software installation script
modifies the /etc/rpc and /etc/syslog.conf files during the installation process. Type
these commands:
cp /etc/rpc /etc/rpc.old
cp /etc/syslog.conf /etc/syslog.conf.old
3. To install the software, type:
pkgadd -d .
4. Press Enter to install all of the packages on the server. Start the NetWorker daemons
only after the last NetWorker package is installed.
Install selected software packages in this order:
a. LGTOclnt (client software package)
b. LGTOnode (storage node software package)
c. LGTOserv (server software package)
d. LGTOman (optional man pages)
5. Start the NetWorker daemons:
/etc/init.d/networker start
6. Type q to exit.
Do not relocate the NetWorkersoftware. By default, the NetWorker is installed in the
/usr directory.
Task 2: Define the NetWorker server as highly available

2. Ensure that the /etc/hosts file on each cluster node contains the name of the logical
host. The logical hostname can be published in the Domain Name System (DNS) or
Network Information Services (NIS).
3. From each node in the cluster that will run the NetWorker server process:
a. Run the cluster configuration script networker.cluster located in /usr/sbin.
This script defines the LGTOserv and the LGTOclnt resource types that the
NetWorker software requires.
b. Type the information specified for each system prompt:
Enter directory where local NetWorker database is installed
[/nsr]?
– Type the location of the local NetWorker database directory provided during the
installation procedure. For example: /space/nsr
Do you wish to configure for both NetWorker server and client?
Yes or No [Yes]?
– Type Yes to configure the server software. This also installs the client software
by default:
– Type No to configure only the client software:
Do you wish to add now the site-specific values for:
NSR_SHARED_DISK_DIR and NSR_SERVICE_ID
Yes or No [Yes]?
– Type Yes to ensure compatibility with other cluster environments:
Enter the Logical Hostname to be used for NetWorker?
– Type the published logical hostname to be used by the highly available
NetWorker server. For example: clus_vir1
In what path will this nsr directory be created/located?
– Type the pathname of the globally mounted /nsr directory that will contain the
configuration information for the highly available NetWorker server. For
example: /global/nw

contain these resources:
◆
Logical hostname
◆
Globally mounted file system for the /nsr area
◆
LGTO.serv resource
◆
LGTO.clnt resource
◆
HAStoragePlus (optional)
To create an instance of the NetWorker Server resource group, perform these steps on one
node in the cluster:
1. Create a resource group:
clresourcegroup create networker
2. Add the logical host resource:
clreslogicalhostname create -g networker clus_vir1
3. (Optional), create an instance of the SUNW.HAStoragePlus resource type:
a. Determine if the HAStoragePlus resource type is registered within the cluster:
clresourcetype list
b. If required, register the HAStoragePlus resource type within the cluster:
clresourcetype register SUNW.HAStoragePlus
c. Create the SUNW.HAStoragePlus resource:
clresource create -g networker -t SUNW.HAStoragePlus -x \
FilesystemMountPoints=/global/clus_vir1/nw,\
/global/clus_vir1/space -x AffinityOn=True hastorageplus
For more information on the SUNW.HAStoragePlus resource and the setup for

clresource create -g networker -t LGTO.clnt -x clientname=clus_vir1
-x owned_paths=/global/clus_vir1/nw,/global/clus_vir1/space client
If the logical host resource name is different than the hostname it specifies, use this
command to do the following:
a. Set the client name to the virtual hostname.
b. Set the optional network_resource property to the logical host resource name.
For example:
clresource create -g networker -t LGTO.clnt \
-x clientname=virtual_hostname -x network_resource=clus_vir1 \
-x owned_paths=/global/clus_vir1/nw,/global/clus_vir1/space
client
5. Create an instance of the LGTO.serv resource type:
clresource create -g networker -t LGTO.serv \
-y Resource_dependencies=clus_vir1 \
-x config_dir=/global/clus_vir1/nw server
If the logical host resource name is different than the hostname it specifies, set the
optional servername property to the virtual hostname:
clresource create -g networker -t LGTO.serv \
-y Resource_dependencies=clus_vir1 \
-x servername=virtual_hostname -x config_dir=/global/clus_vir1/nw \
server
If you are using a HAStoragePlus resource, set the resource_dependencies property to
the HAStoragePlus resource name.
6. Start the NetWorker resource group:
clresourcegroup online networker
Example 1 A highly available NetWorker server
In this example, a highly available NetWorker server uses the logical hostname
backup_server. The highly available NetWorker server uses /global/networker (globally
mounted file system) as its configuration directory.
1. Create a resource group with the name backups:
clresourcegroup create backups
2. Add the logical hostname resource type to the resource group created in the previous
step:
clreslogicalhostname create -g backups backup_server
Install the NetWorker software in a cluster
129
Sun Cluster Version 3.2 Installation
3. Create an instance of the LGTO.serv resource type with the name networker_server.
This resource belongs to the resource group backups and has a dependency on the
logical host created in the previous step.
Specify the configuration directory on the globally mounted file system
/global/networker:
clresource create -g backups -t LGTO.serv \
-y Resource_dependencies=backup_server \
-x config_dir=/global/networker networker_server
4. The NetWorker logical host is also a client of the highly available NetWorker server.
Create an instance of the LGTO.clnt resource type for the logical host backup_server
within the resource group backups. The name of this resource is networker_client:
clresource create -g backups -t LGTO.clnt \
-x clientname=backup_server -x owned_paths=/global/networker \
networker_client
5. Start the highly available service associated with the resource group backups.
clresourcegroup online backups
Task 4: (Optional) add a HAStoragePlus resource
To add a SUNW.HAStoragePlus resource to an existing NetWorker server resource group:
1. Determine whether the HAStoragePlus resource type is registered within the cluster:
clresourcetype list
2. If required, register the HAStoragePlus resource type within the cluster:
clresourcetype register SUNW.HAStoragePlus
3. Create the SUNW.HAStoragePlus resource:
clresource create -g networker -t SUNW.HAStoragePlus -x
FilesystemMountPoints=/global/clus_vir1/nw,/global/clus_vir1/space
-x AffinityOn=True hastorageplus
4. Set up a dependency for the NetWorker Server resource on the HAStoragePlus
resource:
clresource set -y Resource_Dependencies=clus_vir1,hastorageplus
server
5. Verify that the resource dependencies are correctly set:

130
EMC NetWorker Release 8.0 Cluster Installation Guide
Sun Cluster Version 3.2 Installation
Task 5: Grant access to the highly available NetWorker server
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the servers file. For the node that is running the NetWorker
Server resource group, this file is located in the globally mounted file system. Otherwise,
this file is located on a local disk.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To grant access to the highly available NetWorker server:
1. On one node in the cluster:
a. Stop the NetWorker daemon by using the cluster management software, as
follows:
clresourcegroup offline networker
b. Edit or create the servers file in the globally mounted /nsr area. For example,
/global/nw/res/servers:
– Add the set of NetWorker servers, one per line, to be granted access to this
client.
– Add an entry for the NetWorker logical hostname first.
– Add entries for each physical host that can run the NetWorker resource group.
For example:
clus_vir1
clus_phys1
clus_phys2
2. On each node in the cluster:
a. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped:
nsr_shutdown
ps -ef | grep nsr
b. Check the NetWorker boot-time startup file to see whether nsrexecd is being run
with the -s option.
If the -s option exists, remove all occurrences of -s servername in the file.
Install the NetWorker software in a cluster
131
Sun Cluster Version 3.2 Installation
c. Edit or create the /nsr.NetWorker.local/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– Add an entry for the NetWorker logical hostname first.
– Add entries for each physical host that can run the NetWorker resource group.
For example:
clus_vir1
clus_phys1
clus_phys2
d. Restart the NetWorker processes:
/etc/init.d/networker start
3. On one node in the cluster, start the NetWorker daemon by using the cluster
management software, as follows:
clresourcegroup online networker
4. If required, grant access to the NetWorker virtual server on clients outside of the
cluster:
On each client that is outside of the cluster:
a. To shut down the NetWorker processes, type:
nsr_shutdown
b. To verify that all NetWorker daemons have stopped, type:
ps -ef |grep nsr
c. Edit or create the /nsr/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– Add an entry for the NetWorker logical hostname first.
– Add entries for each physical host that can run the NetWorker resource group.
For example:
clus_vir1
clus_phys1
clus_phys2
d. Type this command to restart the NetWorker daemons:
/etc/init.d/networker start
132
EMC NetWorker Release 8.0 Cluster Installation Guide
Sun Cluster Version 3.2 Installation
Task 6: Configure the NetWorker server
To configure the NetWorker server:
1. Log in as root on the cluster node that is currently running the NetWorker server
resource group.
2. Start the NetWorker Console software.
3. From the Administration window, select Properties from the File menu.
a. For the Administrator attribute, add entries for any cluster nodes that are not
already listed. For example:
root@hostname
b. Click Ok.
Task 7: Configure clients under the NetWorker server
When the networker.cluster script runs, it creates a symbolic link named /nsr that points
to a local disk. It also creates a second link named nsr.NetWorker.local that points to the
local NetWorker directory. For example, if the local NetWorker directory was created in
/var/nsr, each client member has these links:
◆
/nsr->/nsr.NetWorker.local
◆
/nsr.NetWorker.local->/var/nsr
To configure each client under the NetWorker server:
1. (Optional) Define save groups.
In order for their save sets to restart after a virtual client or NetWorker server failover,
save groups must have the Autorestart attribute enabled and the Manual Restart
option disabled.
2. Make each physical client within the cluster a client of the NetWorker server. For each
physical client in the cluster:
a. Create a new client.
b. Type the name of the physical client for the Name attribute.
3. Make each virtual client within the cluster a client of the virtual NetWorker server. For
each virtual client in the cluster:
a. Create a new NetWorker client.
b. For the Name attribute, type the name of the virtual client.
c. In the Remote Access attribute, add entries for each physical client within the
cluster. For example:
root@clus_phys1
d. For the Group attribute, select a group.
Install the NetWorker software in a cluster

Sun Cluster Version 3.2 Installation
4. Run a test probe to verify that the Client resource and the Group resource have been
properly configured.
Type this command on the node on which the NetWorker server resides:
savegrp -pv -c client_name group_name
If the test probe does not display the correct scheduled backups and index, refer to
the NetWorker 8.0 Administration Guide.
Task 8: Create instances of the NetWorker Client resource type
An instance of the NetWorker Client resource type must be created for each virtual client
that accesses data on globally mounted file systems. Virtual clients in Sun Cluster 3.2 are
either logical hostnames or shared addresses.
All globally mounted file systems (except the /global/.devices/... file systems) must be
owned by a resource group and defined in a NetWorker Client resource type. If the file
systems are not properly configured, multiple copies will be backed up for each cluster
node.
To back up the data for a virtual client:
1. Create an instance of the NetWorker Client resource as part of an existing resource
group that contains a logical host or shared addresses. For example:
clresource create -g resource_group_name -t LGTO.clnt \
-x clientname=virtual_hostname -x owned_paths=pathname_1,
pathname_2[,...] resource_name
The virtual_hostname variable is a hostname specified by a logical hostname or
Shared Address resource. By default, the logical hostname or shared address resource
name is the same as the first hostname in the list of hostnames the resource controls.
If the logical hostname or shared address resource was explicitly named, set the
optional network_resource property to the resource name:
clresource create -g resource_group_name -t LGTO.clnt \
-x clientname=virtual_hostname
-x network_resource=logicalhostname_or_SharedAddress_resource_name
\
-x owned_paths=pathname_1,pathname_2[,...] resource_name
These examples provide more information:
• “A highly available Informix database server” on page 135
• “A scalable Apache web server” on page 135
2. Run a test probe to verify that the Client and Group resources are properly configured.
Type this command on the node on which the NetWorker server resides:
savegrp -pv -c client_name savegroup_name
If the test probe does not display the scheduled backups and index, refer to the
NetWorker Administration Guide.

hostname informix_lhrs.
An existing failover resource group named informix_rg contains a:
◆
SUNW.informix resource named informix_res
◆
SUNW.LogicalHostname resource named informix_lhrs
This SUNW.informix database server can access data on a global file system under
/global/informix/config and /global/informix/db.
To add a NetWorker virtual client to the existing resource group informix_rg, type:
clresource create -g informix_rg -t LGTO.clnt \
-x clientname=informix_lhrs \
-x owned_paths=/global/informix/config,/global/informix/db \
informix_clntrs

Task 3: Create instances of the NetWorker Client resource type
An instance of the NetWorker Client resource type must be created for each virtual client
that accesses data on globally mounted file systems. Virtual clients in Sun Cluster 3.2 are
either logical hostnames or shared addresses.
All globally mounted file systems (except the /global/.devices/... file systems) must be
owned by a logical host and defined in a NetWorker Client resource type. If the file systems
are not properly configured, multiple copies will be backed up for each cluster node.
To back up the data for a virtual client, from any node in the cluster, create an instance of
the NetWorker Client resource as part of an existing resource group that contains a logical
host or shared address.
For example:
clresource create -g resource_group_name -t LGTO.clnt \
-x clientname=virtual_hostname -x owned_paths=pathname_1,
pathname_2[,...] resource_name
The virtual_hostname variable is the name of the resource used by the Sun Cluster logical
hostname (SUNW.LogicalHostname) or shared address (SUNW.SharedAddress) that you
want to configure as a virtual hostname.
Example 4 A highly available Informix database server
In this example, the Informix database server is configured to use the DNS registered
hostname informix_lhrs.
An existing failover resource group named informix_rg contains a:
◆
SUNW.informix resource named informix_res
◆

Task 4: Define the list of trusted NetWorker servers
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the servers file. For the node that is currently running the
NetWorker Server resource group, this file is located in the globally mounted file system.
Otherwise, this file is located on a local disk.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To define the list of trusted NetWorker servers, perform these steps on each node in the
cluster:
1. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped:
nsr_shutdown
ps -ef |grep nsr
2. Edit or create the /nsr/res/servers file and add the set of NetWorker servers, one per
line, that require access to this client.
3. Check the NetWorker boot-time startup file to see whether nsrexecd is being run with
the -s option. If the -s option exists, remove all occurrences of this from the file:
-s servername
4. Restart the NetWorker daemons:
/etc/init.d/networker start
144

Task 5: Configure clients under the NetWorker server
To configure the NetWorker server:
1. Make each physical client within the cluster a client of the NetWorker server. For each
physical client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the physical client.
If a physical client is backed up to a NetWorker server outside the cluster, the name of
any virtual service that can run on the physical node must be added to the Remote
Access list of the physical Client resource.
2. Make each virtual client within the cluster a client of the NetWorker server.
For each virtual client in the cluster:
a. Create a new client.
b. For the Name attribute, type the name of the NetWorker server.
c. For the Remote Access attribute, add entries for each physical client in the cluster.
For example:
root@clus_phys1
d. For the Group attribute, select a group.
3. Schedule backups by using the NetWorker application.
The NetWorker server might reside outside of the cluster.
Install the NetWorker software in a zone cluster
The NetWorker client and storage node software is supported in a Solaris zone cluster. The
NetWorker server software is not supported in a Solaris zone cluster.
It is not required that the global zone cluster be configured for the NetWorker software to
support non-global zone clusters. These are the two types of non-global zone root file
systems that can be included in a cluster:
◆
whole root
◆
sparse root
Obtain the appropriate documentation from the Sun website for configuration information
on Solaris zone clusters.

Uninstall the NetWorker software
To uninstall the NetWorker software from a cluster environment:
1. Log in to the node in the cluster that is running the nsrd daemon as root.
2. Take the NetWorker resource group offline.
For example:
clresourcegroup offline networker
3. Stop the NetWorker daemons on all of the nodes in the cluster.
For example:
nsr_shutdown
4. Remove the NetWorker resource from the cluster.
For example:
clresource disable nwclient
clresource disable nwserver
clresource delete nwclient
clresource delete nwserver
networker.cluster -r
5. Log in to the other cluster node as root.
6. Remove the NetWorker resource from the cluster.
For example:
networker.cluster -r
clresourcegroup delete networker
If the clresourcegroup command results in a message similar to the following: (Error:
(C517101) networker: resource group contains resources; cannot delete), the
hastorageplus resource might still exist.
148
EMC NetWorker Release 8.0 Cluster Installation Guide

Configure an external client to a virtual server
Use this procedure to configure and back up an external NetWorker client to a highly
available NetWorker server.
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the servers file.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
On each NetWorker client that is outside of the cluster:
1. Shut down the NetWorker processes:
nsr_shutdown
2. Verify that all NetWorker daemons have stopped:
ps -ef |grep nsr
3. Edit or create the /nsr/res/servers file:
a. Add the set of NetWorker servers, one per line, that require access to this client.
b. Add an entry for the NetWorker logical hostname first. Then add entries for each
physical host that can run the NetWorker resource group. For example:
– clus_vir1
– clus_phys1
– clus_phys2
Define ownership of a raw partition for virtual clients
To back up the raw partitions of a NetWorker virtual client, ensure that the raw device path
appears in the owned paths field of the LGTO.clnt resource.

Cluster configuration
Figure 6 on page 154 displays a general cluster configuration consisting of two or more
nodes and at least one virtual server. In this illustration:
◆
Node 1 is a computer with its own Local Disk.
◆
Node 2 is a computer with its own Local Disk.
◆
Virtual Server owns Shared Disks.
In this example, the virtual server, clus_log1, can fail over between Node 1 and Node 2.
However, the server runs only on one node at a time.
The NetWorker client software runs on all the physical nodes within the cluster. This allows
the backup of the physical client to proceed, as long as the node is running. Only one
instance of the client software (nsrexecd) runs on each physical node within the cluster.
The NetWorker client software is designed to recognize more than one client (physical
client plus virtual client) that might be associated with a single physical node.

run the NetWorker service group.
On Solaris and Linux
To prepare to install the software:
1. Ensure that the operating environment and the VERITAS Cluster Server 3.5, 4.0 or 5.0
software are already installed and configured on all cluster nodes.
2. If the VERITAS Cluster Server installation and configuration directories are different
from the default directories, set the following environment variables:
• VCS_HOME
The default directory is /opt/VRTSvcs.
• VCS_CONF
The default directory is /etc/VRTSvcs.
Software requirements
155
VERITAS Cluster Server Installation
3. Ensure that the PATH environment variable includes /usr/sbin and $VCS_HOME/bin.
The the default directory is /opt/VRTSvcs/bin.
To install the NetWorker software on the computer designated as the NetWorker client:
1. Access the NetWorker software from the distribution media.
2. Install the NetWorker client software on the physical disk of each node in the cluster to
be backed up.
The NetWorker Installation Guide provides detailed installation instructions.
On Windows
To install the NetWorker client software on each node in the cluster:
1. Ensure that the operating system is updated with the most recent cluster patch.
2. Install the NetWorker client software on the physical disk of each node in the cluster to
be backed up.
Task 2: Define the NetWorker server as a highly available application
The following steps define the NetWorker Server as a Highly Available Application on VCS.
On Solaris and Linux
1. Log in as root.
2. Ensure that the /etc/hosts file on each cluster node contains the names of the virtual
hosts. The virtual hostnames can be published in the Domain Name System (DNS) or
Network Information Services (NIS).
3. From each node in the cluster that will run the NetWorker server process:
a. Run the cluster configuration script networker.cluster located in /usr/sbin.
This script creates NWClient resource types that may need to be added later (see
“Task 4 (Optional): Create NetWorker Client resource instances”) to the VERITAS
Cluster Server configuration.
b. In response to the following prompts:
Enter the directory where the local NetWorker database is
installed [/nsr]?
– Enter the location of the local NetWorker database directory provided during
the installation procedure. For example: /space/nsr
Do you wish to configure for both NetWorker server and client?
Yes or No [Yes]?
– Enter Yes to configure the server software. This also installs the client software
by default.
Do you wish to add now the site-specific values for:
NSR_SHARED_DISK_DIR and NSR_SERVICE_ID Yes or No [Yes]?
– Enter Yes to ensure compatibility with other cluster environments.
In what path will the shared nsr directory be created/located?
156
EMC NetWorker Release 8.0 Cluster Installation Guide
VERITAS Cluster Server Installation
– Enter the pathname of the globally mounted /nsr directory that will contain the
configuration information for the highly available NetWorker server. For
example: /global/nw.
Enter the Logical Hostname to be used for NetWorker?
– Enter the published logical hostname to be used by the highly available
NetWorker server. For example: clus_vir1
To undo any changes to the configuration, run the networker.cluster -r script and then run
the networker.cluster script again.
On Windows
1. Log in as Administrator on each node where the NetWorker software is being installed.
2. Ensure that the C:\WINDOWS\system32\drivers\etc\hosts file on each cluster node
contains the names of the virtual hosts. The virtual hostnames can be published in the
Domain Name System (DNS) or Network Information Services (NIS).
3. For each node in the cluster:
a. Run the cluster configuration binary, <NSR_BIN>\lc_config.exe.
This script creates NWClient resource types that may need to be added later (see
“Task 4 (Optional): Create NetWorker Client resource instances”) to the VERITAS
Cluster Server configuration.
b. In response to the following prompts:
Do you want to configure NetWorker virtual server?[y/n]
– Enter y. This configures both the server software and the client software.
– Enter shared nsr dir:
– Enter the pathname of the shared nsr directory that will contain the
configuration information for the highly available NetWorker server. For
example: S:\nsr.
– Enter the directory in which your Veritas Cluster Server software is installed
(typically something like C:\Program Files\Veritas\cluster server):
– Enter the location where the Veritas Cluster Server is installed.
Any changes to the configuration can be undone by running the lc_config.exe -r option and
then running the lc_config.exe again.

Task 3: Define a NetWorker service group
A NetWorker service group should be defined in VCS to make the NetWorker server highly
available. For Solaris and Linux platforms, the VCS Application agent is used to control the
NetWorker virtual server. For Windows platforms, the VCS Process agent is used to control
the NetWorker virtual server. The following are examples of NetWorker service group
definitions on Linux and Windows.
Dependencies should be set up between resources — for example, on Solaris and Linux
platforms, the Application resource depends on the IP resource, which depends on the
Mount resource.
Example 7 An instance of a NetWorker service group definition on Linux
group networker (
SystemList = { arrow = 0, canuck = 1 }

On Windows, it is required to set the CleanProgramTimeout attribute of the NetWorker
server process to a minimum value of 180, and the StopProgramTimeout attribute to a
minimum of value of 120.
Task 4 (Optional): Create NetWorker Client resource instances
An instance of the NetWorker Client resource (NWClient) might be required for virtual
clients that own data on shared devices. Virtual clients in the VERITAS Cluster Server are IP
type resources.
Depending on the VERITAS Cluster service group configuration, this task might not be
required. If required, create an instance of NWClient resource type in VERITAS Cluster
service groups that:
◆
Are parallel with one or more IP type resources.
◆
Contain raw devices or logical volumes to back up.
◆
Contain more than one IP type resource.
◆
Contain storage resources that are not automatically detected such as:
• Storage resources that are defined in dependent groups.
• Storage resources that are not of the type Mount or CFSmount.
Install the NetWorker server in a cluster
159
VERITAS Cluster Server Installation
Creating an instance of NWClient resource type is optional if the following conditions exist:
◆
The failover VERITAS Cluster service group has only one IP type resource.
◆
The owned filesystems on the shared devices are instances of the mount type
resource contained in the same service group.
Check the VERITAS Cluster Server configuration to determine which, if any, service groups
require one or more NWClient resources. If no such groups require NWClient resources,
proceed to “Task 5: Grant access to the highly available NetWorker server” on page 163.
About the NWClient resource
Before performing this task, review the information in this section to become familiar with
the structure of an NWClient resource.

Task 5: Grant access to the highly available NetWorker server
Before a NetWorker server can back up a client, the client must grant the server access.
Granting access is controlled by the servers file. For the node that is running the NetWorker
Server service group, this file is located in the shared file system. Otherwise, this file is
located on a local disk.
Consider the following:
◆
If no servers are specified, any NetWorker server can backup this client.
◆
If no servers are specified, any NetWorker server can perform a directed recovery to
the client.
◆
When adding NetWorker servers, specify both the short name and FQDN for each
NetWorker server.
To grant access to the highly available NetWorker server:
1. On one node in the cluster:
a. Stop the NetWorker daemon by using the cluster management software.
b. Edit or create the servers file in the shared nsr area (for example, on Solaris and
Linux, /global/nw/res/servers; on Windows, S:\nsr\res\servers):
– Add the set of NetWorker servers, one per line, to be granted access to this
client.
– Add an entry for the NetWorker logical hostname first.
– Add entries for each physical host that can run the NetWorker resource group.
For example:
clus_vir1
clus_phys1
clus_phys2
2. On each node in the cluster:
a. Shut down the NetWorker processes and verify that all NetWorker daemons have
stopped. For example, on Solaris and Linux, enter:
nsr_shutdown
ps -ef | grep nsr
b. Check the NetWorker boot-time startup file to see whether nsrexecd is being run
with the -s option.
If the -s option exists, remove all occurrences of -s servername in the file.

c. Edit or create the local servers file:
– On Solaris and Linux, the file is /nsr.NetWorker.local/res/servers
– On Windows, it is C:\Program Files\EMC NetWorker\nsr\res\servers
Perform the following to the local servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– Add an entry for the NetWorker logical hostname first.
– Add entries for each physical host that can run the NetWorker resource group.
For example:
clus_vir1
clus_phys1
clus_phys2
3. On one node in the cluster, start the NetWorker daemon by using the cluster
management software.
4. If required, grant access to the NetWorker virtual server on clients outside of the
cluster on each client:
a. Shut down the NetWorker processes.
b. Verify that all NetWorker daemons have stopped.
c. Edit or create the /nsr/res/servers file:
– Add the set of NetWorker servers, one per line, that require access to this client.
– Add an entry for the NetWorker logical hostname first.
– Add entries for each physical host that can run the NetWorker resource group.
For example:
clus_vir1
clus_phys1
clus_phys2
Task 6: Configure the NetWorker virtual server
To configure the NetWorker virtual server:
1. Log in as root (on Solaris and Linux) or Administrator (on Windows) on the cluster
node that is currently running the NetWorker server resource group.
2. Start the NetWorker Console software:
a. From the Console window, click Enterprise.
b. From the left pane, select the Enterprise icon. The NetWorker server appears in the
right and left panes.
c. From the left pane, select the NetWorker server.
d. From the right pane, select the NetWorker application.
e. From the Enterprise menu, select Launch Application.The Administration window
launches.

VERITAS Cluster Server Installation
3. From the Administration window, click Configuration.
a. In the left pane, select the NetWorker server.
b. From the File menu, select Properties. The Properties dialog box appears.
– For the Administrator attribute, add entries for any cluster nodes that are not
already listed. For example, on Solaris or Linux, root@hostname.
– Click Ok.
Task 7: Configure clients under the NetWorker virtual server
On Solaris and Linux, when the networker.cluster script runs, it creates:
◆
A symbolic link named /nsr that points to a local disk.
◆
A second link named nsr.NetWorker.local that points to the local NetWorker directory.
For example, if the local NetWorker directory was created in /var/nsr, each client member
has these links:
◆
/nsr->/nsr.NetWorker.local
◆
/nsr.NetWorker.local->/var/nsr
To configure each client under the NetWorker virtual server:
1. (Optional) Define save groups.
In order for their save sets to restart after NetWorker server failover, save groups must
have the Autorestart attribute enabled and the Manual Restart option disabled.
2. Make each physical client within the cluster a client of the NetWorker virtual server. For
each physical client in the cluster:
a. Create a new client.
b. Type the name of the physical client for the Name attribute.
3. Make each virtual client within the cluster a client of the virtual NetWorker server. For
each virtual client in the cluster:
a. Create a new NetWorker client.
b. For the Name attribute, type the name of the virtual client.
c. In the Remote Access attribute, add entries for each physical client within the
cluster. For example, on Solaris and Linux:
root@clus_phys1
d. For the Group attribute, select a group.

4. Run a test probe to verify that the Client resource and the Group resource have been
properly configured.
Type this command on the node on which the NetWorker server resides:
savegrp -pv -c client_name group_name
If the test probe does not display the correct scheduled backups and index, refer to
the EMC NetWorker 8.0 Administration Guide.
Task 8: Register licenses for the highly available NetWorker server
To register and license the highly available NetWorker server:
1. Order licenses for the type of NetWorker server and client configuration in use.
2. Log in to the system that is currently running the NetWorker resource group.
3. Perform these operations to enter the purchased enabler codes:
a. If you have been evaluating the NetWorker highly available software and have now
purchased the software:
– To upgrade from the base evaluation enabler to the purchased enabler, type:
nsrcap -v -u base_enabler_code
– Delete any remaining evaluation enablers:
nsradmin -s clus_vir1
This eliminates warning messages due to expiring evaluation enablers.
b. For each enabler code, type:
nsrcap -v -c enabler_code
4. Ensure that the highly available NetWorker server is defined as a part of the cluster.
5. Run the following command, and capture the output, on each node that is currently
running the NetWorker server resource group:
hostid
The numeric identifier of the current host prints.
6. Log in to the system that is running the NetWorker virtual server and create the
/nsr/res/hostids file. This file contains the host IDs of all the cluster nodes.
Use this syntax:
hostid1:hostid2:hostid3:...
For example:
12345678:87654321
7. Restart the server by taking the highly available NetWorker server offline and then
putting it back online.
166

Tracking scheduled saves
To verify that the Client and Group resources are properly configured, run a test probe for
each client from the node where the NetWorker application is running:
savegrp -pv -c client_name group_name
If the test probe does not display all the scheduled save sets:
◆
Check the cluster configuration by using the cluster management software. If
necessary, reconfigure the cluster.
◆
Ensure that the save sets defined for the client are owned by that client. If necessary,
redistribute the client save sets to the appropriate Client resources.
Misconfiguration of the Cluster resources might cause scheduled save sets to be
dropped from the backup. The NetWorker Administration Guide provides more
information.
◆
Type this command to override scheduled save rules:
On Solaris and Linux:
touch networker_bin_dir/pathownerignore
On Windows:
echo NUL: networker_bin_dir\pathownerignore
This command allows any path to be backed up for a client, whether it is owned by the
virtual client or physical node. The NetWorker Administration Guide provides more
information.
◆
Run a second test probe to verify the configuration.
If the pathownerignore file was used, check that the NetWorker scheduled save uses the
correct client index. If the wrong index is used, the save sets can be forced to go to the
correct index:
1. From the NetWorker Administration window, select a client and edit its properties.
2. For the Backup Command attribute, type the name of a backup script that contains:
