CHAPTER 1

Introduction

This document describes how to configure and use the NetWorker software in a clustered environment. This guide also provides cluster specific information that you need to know before you install NetWorker on a clustered host. You must install the NetWorker software on each physical node in a cluster.

This guide does not describe how to install the NetWorker software. The EMC NetWorker

Installation Guide ways:

describes how to install the NetWorker software on supported operating systems. You can configure the NetWorker software in a cluster in one of the following l l l

Stand-alone application

......................................................................................14

.................................................................................. 14

Introduction

Introduction

Stand-alone application

When you install the NetWorker server, storage node, or client software as a stand-alone application, the required daemons run on each node. When the NetWorker daemons stop on a node, the cluster management software does not restart them automatically.

In this configuration: l l l l

NetWorker does not know which node owns the shared disk. To ensure that there is always a backup of the shared disks, you must configure a NetWorker client resource for each physical node to back up the shared and local disks.

Shared disk backups will fail for each physical node that does not own or control the shared disk.

NetWorker writes client file index entries for the shared backup to the physical node that owns the shared disk.

To recover data from a shared disk backup, you must determine which physical node owned the shared disk at the time of backup.

Cluster-aware application

On supported operating systems, when you configure a cluster-aware NetWorker client or server, all required daemons run on each physical node. When the NetWorker daemons stop on a node, the Cluster Management software does not restart them automatically.

A cluster-aware NetWorker application determines path ownership of the virtual applications that run in the cluster. This allows the NetWorker software to back up the shared file system and write the client file index entries for the virtual client.

When you configure a cluster-aware NetWorker application, you must: l l l

Create a NetWorker client resource for the virtual node in the cluster to back up the shared disk.

Create a NetWorker client resource for each physical node to back up the local disks.

Select the virtual node to recover data from a shared disk backup.

Highly available application

On supported operating systems, you can configure the NetWorker server software as a highly available application. A highly available NetWorker server is also called a

NetWorker virtual server.

When the NetWorker server software is a highly available application: l l

The active node runs the NetWorker server daemons and accesses the global /nsr directory on the shared drive.

The passive nodes run the NetWorker client daemon, nsrexecd.

l l l

When a failover occurs, the new active node runs the NetWorker server daemons.

The NetWorker virtual server uses the IP address and hostname of the NetWorker virtual host, regardless of which cluster node owns the NetWorker server application.

NetWorker determines path ownership of the virtual applications that run in the cluster. This allows the NetWorker software to back up the shared file system and write the client file index entries for the virtual client.

When you configure a highly available NetWorker server, you must:

Introduction l l l

Create a NetWorker client resource for the virtual node in the cluster to back up the shared disk.

Create a NetWorker client resource for each physical node to back up the local disks.

Select the virtual node to recover data from a shared disk backup.

The following figure provides an example of a highly available NetWorker server in a general cluster configuration consisting of two nodes and one virtual server. In this illustration: l l l

Node 1, clus_phy1 , is a physical node with local disks.

Node 2, clus_phy2 , is a physical node with local disks.

Virtual Server, clus_vir1: n n

Owns the shared disks. A volume manager manages the shared disk.

Can fail over between Node 1 and Node 2. However, the NetWorker server software only runs on one node at a time.

CHAPTER 2

Configuring the Cluster

This chapter describes how to prepare for a NetWorker installation on a cluster and how to configure NetWorker on each cluster. Perform these steps after you install the

NetWorker software on each physical node.

The steps to install and update the NetWorker software in a clustered environment are the same as installing and updating the software in a non-clustered environment. The

EMC NetWorker Installation Guide describes how to install NetWorker on each supported operating system.

Configuring the Cluster

Prepare to install NetWorker on a cluster

This section provides general information to review before you install the NetWorker software on the nodes in a cluster.

l l l l l l l

On all supported cluster platforms, ensure that the cluster services start before the

NetWorker services start. If the cluster services start after the Networker services start, then the NetWorker software exhibits undesirable behavior.

Ensure that the physical and virtual node names are resolvable in Domain Name

System (DNS) or by using a hosts file.

Ensure that the output of the hostname command on a each physical node corresponds to an IP address that can be pinged.

You can publish the virtual host name in the DNS or Network Information Services

(NIS).

Install the most recent cluster patch for the operating system.

Install the NetWorker software in the same location on a private disk, on each cluster node.

Connect a dedicated shared disk and file system to each node within the cluster. The

NetWorker software creates a directory on the shared disk. If the client resource for a virtual client is not properly configured in NetWorker server, then the backup of the shared drives will fail.

AutoStart

This section describes how to prepare the AutoStart cluster before you install the

NetWorker software. This section also describes how to configure the NetWorker server software as a highly available application and the NetWorker client as a cluster-aware application, after you install the NetWorker software on each physical node of the cluster.

The NetWorker Installation Guide describes how to install the NetWorker software.

Note

This section does not apply when you install NetWorker as a stand-alone application.

Prepare to install NetWorker on AutoStart

Review this section before you install the NetWorker software on an AutoStart cluster.

l l

Always run two primary controllers. Use the AutoStart Console to promote at least one secondary node to the primary. If one node fails, then the other node automatically comes online with all of the data. The AutoStart documentation provides detailed instructions.

AutoStart for Windows only: n n

On one node, create a folder for the managed, shared disk. For example, s:\nsr.

Do not share the folder. If the AutoStart software is already installed and a managed shared disk already exists, then remove the share property. The

NetWorker software installation fails when the share property exists.

For each physical node in the cluster, ensure that the AutoStart Console user account, NT AUTHORITY\SYSTEM, has local administrator access.

Preparing to install NetWorker on HACMP/PowerHA SystemMirror

Review this section before you install the NetWorker software on HACMP/PowerHA

SystemMirror.

l

To back up a physical client: l l l l n n

Each node requires persistent IPs or an extra NIC that is configured outside of the control of the HACMP environment.

NetWorker requires an address that uniquely connects to a physical client. The service and boot addresses of HACMP for AIX do not meet this requirement because a cluster configured with IP address takeover (IPAT) replaces the boot address with the service address, when a resource group is attached.

Define a service IP label for the NetWorker virtual server.

If you use IP address takeover (IPAT) and you do not define a resource group, then you must use the boot address to connect to the host. Service addresses are associated with a resource group, not physical nodes.

Set the hostname to the name equivalent to the address that the dedicated NIC of the physical client uses. Configure this NIC as the primary network adapter, for example, en0. A highly available NetWorker server does not require an extra NIC outside of the control of HACMP/PowerHA SystemMirror.

Service addresses are associated with a resource group, not physical nodes. The output of the hostname command on a computer must correspond to a pingable IP address. The computer hostname must also be set to the name equivalent of the address used by the physical client’s persistent IP or dedicated NIC. Whether you use persistent IP or dedicated NIC, you must use the primary network adapter (for example, en0).

Configuring a cluster-aware NetWorker client

A cluster-aware NetWorker client is aware of the clustered IP address and shared file systems in a cluster. Perform these steps to configure a cluster-aware NetWorker client, which allows you to create a client resource for the virtual node.

This section also describes how to configure the NetWorker server software as a highly available application and the NetWorker client as a clusteraware application, after you install the NetWorker software on each physical node of the cluster.

The NetWorker Installation Guide describes how to install the NetWorker software.

Note

This section does not apply when you install NetWorker as a stand-alone application.

Preparing to install NetWorker on MC/ServiceGuard

Review this section before you install the NetWorker software on MC/ServiceGuard.

l l

NetWorker 8.0 and later does not support an MC/ServiceGuard NetWorker server running on the PA_RISC architecture. The NetWorker Online Software Compatibility

Guide provides the most up-to-date information about software requirements.

To ensure the cluster services automatically start after a reboot, set the

AUTOSTART_CMCLD=1 value in the /etc/rc.config.d/cmcluster file.

l

For HP-UX11.11/ServiceGuard11.16 only, perform the following steps to ensure that the NetWorker daemons start:

1. Edit the /opt/networker/bin/nsr_mk_cluinfo.sg

2. Search for the following line:

FS=`cmgetconf -v 0 -p ${pkg_name}

3. Remove the 0 from the -v option:

FS=`cmgetconf -v -p ${pkg_name}

4. Save the file.

Configuring the NetWorker on MC/ServiceGuard

After you install the NetWorker software on each physical node, you can use the LC integration framework method or the non-LC integration framework method to configure the NetWorker software.

The benefits of using the LC integration framework method include: l l l

Support for 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. The configuration process automatically creates and uses the nsr_mk_cluinfo and lcmap files in the /opt/networker/bin directory.

HP MC/ServiceGuard

27

Configuring the Cluster

Non-LC integration framework method only - creating configuration files

This section describes how to create the configuration files that the non-LC integration framework method requires when you configure the NetWorker package in the cluster.

Procedure

1. On the active node, create the NetWorker.clucheck and .nsr_cluster file in the /etc/cmcluster directory.

For example: touch /etc/cmcluster/NetWorker.clucheck

touch /etc/cmcluster/.nsr_cluster

Note

Ensure everyone has read ownership and access permissions for the .nsr_cluster

file.

2. Define the mount points that the MC/ServiceGuard or MC/LockManager package owns in the .nsr_cluster file. Include the NetWorker shared mount point.

For example:

pkgname:published_ip_address:owned_path[:...] where: l published_ip_address is the IP address assigned to the package that owns the shared disk. Enclose IPv6 addresses in square brackets. You can enclose IPv4 addresses in square brackets, but it is not necessary.

l owned_path is the path to the mount point. Separate additional paths with a colon.

For example: l

IPv6 address: l networker:[3ffe:80c0:22c:74:230:6eff:fe4c:2128]:/share/nw

IPv4 address: networker:192.168.109.10:/share/nw

Note

An HP-UX MC/ServiceGuard package that does not contain a disk resource does not require an entry in the.nsr_cluster file. If an online diskless package is the only package on that cluster node, cmgetconf messages may appear in the /var/ admin file during a backup.

To avoid these messages, allocate a mounted file system to a mount point, then add this mount point, the package name, and the IP address to the .nsr_cluster file. The NetWorker software does not back up the file system. However, you can mount the file system on each cluster node that the diskless package might fail over to.

3. Copy the NetWorker.clucheck and .nsr_cluster file to the /etc/ cmcluster directory, on each passive node.

EMC NetWorker Cluster 8.2 SP1 Integration Guide

Configuring the Cluster

Preparing to install NetWorker on MSFCS clusters

Review this section before you install the NetWorker software on a MSFCS cluster.

l

Reboot the cluster node after you install the NetWorker software. If you do not reboot, you cannot start the cluster administrator program. If you cannot start the cluster administrator program, then close the cluster administrator interface and reload the software by running the following command, from the command line: l l l regsvr32 /u nsrdresex.dll

To back up a host that is a member of multiple domains, an Active Directory (AD) domain, and a DNS domain, you must define the AD domain name in: n

The host file on the NetWorker server.

n

The Alias attribute for the Client resource on the NetWorker server.

The WINDOWS ROLES AND FEATURES save set includes the MSFCS database. When you back up the WINDOWS ROLES AND FEATURES save set, NetWorker will automatically back up cluster configuration. The cluster maintains the MSFCS database synchronously on two nodes, as a result the database backup on one node might not reflect changes made on the other node.

The NetWorker Server and Client software supports backup and recovery of file system data on Windows Server 2012 and Windows Server 2012 R2 File Servers configured for Windows Continuous Availability with Cluster Shared Volumes (CSV).

Support of CSV and deduplicated CSV backups include levels Full, Incremental, and incr_synth_full. NetWorker supports CSV and deduplicated CSV backups with the following restrictions: n n

The volume cannot be a critical volume.

NetWorker cannot shadow copy a CSV and local disks that are in the same volume shadow copy set.

Note

The NetWorker software does not protect the Microsoft application data stored on a

CSV or deduplicated CSV, such as SQL databases or Hyper-V virtual machines. To protect Microsoft application data use the NetWorker Module for Microsoft (NMM) software. The NMM documentation provides more information about specific backup and recovery instructions of Microsoft application data.

The section Windows Optimized Deduplication in the NetWorker Administration

Guide provides more information about performing a backup and recovery of deduplicated CSV volumes.

Before you install the NetWorker software: l l l l

Install Volume Manager software in the cluster. For example: Solaris Volume

Manager.

Configure a shared disk as a mount point for the global file system to contain the shared /nsr directory.

Ensure that the PATH environment variable includes the /usr/sbin and /usr/ cluster/bin directories.

Ensure that a resource group owns each globally mounted file system (except the / global/.devices/... file system). To enable a resource group to own a globally mounted file system (except the /global/.devices/... file systems), specify the file system in only one NetWorker Client type resource. If you incorrectly configure the ownership of global file systems in a NetWorker client type resource, then multiple backup copies occur for each cluster node.

4. On one node in the cluster, create a resource group for the backup and a resource instance for the LGTO.clnt resource: a. Create a resource group: clresourcegroup create resource_group_name

For example, to create the resource group backups, type: clresourcegroup create backups

Note

A resource group must own all globally mounted file systems (except the / global/.devices/... file systems). All globally mounted filesystems (except the / global/.devices/... file systems) must have a NetWorker Client resource type. A misconfigured file system results in multiple backup copies for each cluster node.

b. Add the logical hostname resource type to the new resource group: clreslogicalhostname create -g resource_group_name logical_name

For example, when the logical hostname is clus_vir1, type: clreslogicalhostname create -g backups clus_vir1 c. Optionally, to create an instance of the SUNW.HAStoragePlus resource type: l

Determine if the HAStoragePlus resource type is registered within the cluster: l clresourcetype list

If required, register the HAStoragePlus resource type within the cluster: l clresourcetype register SUNW.HAStoragePlus

Troubleshooting configuration

This section describes how to troubleshoot NetWorker configuration issues in a cluster.

l l

Slow backups or slow nsrd startup times on page 54

NetWorker virtual server fails to start nsrmmd on page 56

Slow backups or slow nsrd startup times

The lcmap program, queries cluster nodes and creates a map that includes information such as path ownership of resource groups. In large cluster configurations, lcmap may take a long time to complete and thus slow down certain operations. This is most often noticed in slow NetWorker server (nsrd) start times or in very long backup times.

In these situations, consider adjusting cluster cache timeout. This attribute specifies a time, in seconds, in which to cache the cluster map information on a NetWorker client.

Edit the cluster cache timeout attribute with caution. Values for the attribute can vary from several minutes to several days and depends the following factors: l l

How often the cluster configuration changes.

The possibility of resource group failover.

l

The frequency of NetWorker operations.

If you set the value too large, then an out-of-date cluster map can result and cause incorrect path resolution. For example, if the cluster cache timeout value is set to 86400

(one day), then any changes to the cluster map will not be captured for up to one day. If cluster map information changes before the next refresh period, then some paths may not resolve correctly.

54

EMC NetWorker Cluster 8.2 SP1 Integration Guide

Configuring the Cluster

Note

If you set the value too small, then cache updates can occur too frequently, which negatively affects performance. Experiment with one physical cluster node to find a satisfactory timeout value. If you cannot obtain a significant improvement in performance by adjusting this attribute, then reset the attribute value to 0 (zero). When the attribute value is 0, NetWorker does not use the attribute.

Editing the cluster cache timeout attribute

The cluster cache timeout attribute resides in the NSRLA database of the NetWorker client and is visible only when NetWorker is configured for a cluster. For example on UNIX, a

NetWorker client is configured for a cluster when the networker.cluster script is executed and nsrexecd is restarted.

NOTICE

If the timeout value will be modified, it is recommended that you edit the initial cluster cache timeout value before bringing the highly available NetWorker server online.

To edit the cluster cache timeout value, take the highly available NetWorker server offline and perform these steps on each physical node as the root user on UNIX or an administrator on Windows:

Procedure

1. Connect to the NSRLA database.

l

For the passive node, type: l nsradmin -p nsrexecd

For the active node, type: nsradmin -d directory where directory is the location of the local NSRLA database: n

UNIX: /nsr.NetWorker.local/res/nsrladb.

n

Windows: NetWorker_install_path nsr\res\nsrladb.

2. Display the current settings for attributes in the NSRLA resource. For example, type: print type:NSRLA

3. Change the value of the cluster cache timeout attribute. For example, type: update cluster cache timeout: value where value is the timeout value in seconds. A value of 0 (zero) specifies that the cache is not used.

4. When prompted to confirm the change, type Yes.

5. Confirm the attribute updated successfully. Type: print type:NSRLA

6. Bring the highly available NetWorker server online. NetWorker updates the shared

NSRLA database with the new cache value.

The updated value takes effect after the next cache update, based on the previous timeout value.

To make the timeout value take effect immediately, delete the cache file on the physical node that owns the NetWorker virtual server:

CHAPTER 3

Configuring Devices for a Highly Available

NetWorker Server

NetWorker supports the use of tape, AFTD, and Data Domain devices to back up cluster host data. This chapter describes three common configuration scenarios when using autochangers and tape devices to back up a highly available NetWorker server. The information that describes how to configure AFTD and Data Domain devices in the

NetWorker Administration Guide and Data Domain Integration Guide applies to clustered and non-clustered hosts.

Configuring Devices for a Highly Available NetWorker Server

Configuring an autochanger with shared tape devices

In this configuration, the NetWorker virtual server manages the robotic arm. NetWorker uses Dynamic Drive Sharing (DDS) to allow the virtual node and each physical node to shares tape devices. Each physical and virtual node sends backup data directly to a tape device and not over the network. Use this configuration when most of the backup data originates from the inactive physical node.

Before you configure a shared autochanger and DDS devices, perform the following steps:

Procedure

1. Ensure that the

device-sharing infrastructure on page 90

supports complete isolation and protection of the path session between the autochanger and the node that owns the NetWorker server resource. Protect the path from stray bus signals and unauthorized session access from the other nodes.

Note

If processes on nodes other than the one that owns on the NetWorker server can access the tape devices, data corruption might occur. The NetWorker software might not detect the data corruption.

2. Zone the robotic arm and all drives to each physical node in the cluster.

3. Configure the same path (bus, target and LUNs) to the robotics and tape drives on each node.

4. If you configured the bridge with node device-reassignment reservation commands, then add these commands to the nsrrc startup script on the NetWorker virtual server. The NetWorker Administration Guide describes how to modify the nsrrc script.

5. Install the cluster vendor-supplied special device file for the robotic arm on each physical node. The special device file creates a link to the tape or autochanger device driver. Ensure that the name assigned to the link is the same on each node for the same device. If you do not have matching special device files across cluster nodes, you may need to install fibre HBAs in the same PCI slots on all the physical nodes within the cluster.

The following figure provides a graphical view of this configuration option.

describes how to configure the Client resource for each cluster node.

9. When a failover occurs, NetWorker relocates and restarts savegroup operations that were in progress on the failover node. Standard autochanger operations however, (for example: performing an inventory, labeling, mounting or unmounting a volume) will not automatically restart on the new failover node.

Configuring an autochanger with non-shared tape devices

Configuring Devices for a Highly Available NetWorker Server resource sends backup data directly to the tape devices. The inactive physical node sends backup data to the tape devices over the network. Use this configuration when most of the backup data originates from the active physical node, the shared disk resource, and hosts external to the cluster.

The following figure provides a graphical view of this configuration option.

Configuring the robotics on a stand-alone host

You can set up a stand-alone physical host as a storage node outside the cluster to control the robotic arm when you cannot match bus target LUNs across the cluster nodes or when you do not have a NetWorker server within the cluster. The stand-alone physical host can control the robotic arm through a Fibre Channel or SCSI connection. Each node in the cluster sends backup data over the network to the tape devices. The NetWorker virtual server requires a local device to back up the indexes and bootstrap.

The following figure provides a graphical view of this configuration option.

Registering NetWorker virtual server licenses

NetWorker uses the hostid of the NetWorker server to generate authorization codes for the license keys. For a NetWorker virtual server, you must determine the hostid of the each physical node and create a composite hostid. A composite hostid is a combination of the hostids for each node, that makes up a highly-available NetWorker server.

NetWorker stores the composite hostid value in a hostids file in the shared nsr directory.

Use the composite hostid to register and license a highly-available NetWorker server.

When a failover occurs, the licenses for the NetWorker virtual server do not require authorization.

Note

The NetWorker Licensing Guide describes how to obtain NetWorker licenses and how to add them to a NetWorker server.

To create a composite hostid:

Procedure

1. Determine the hostid of a physical node: l

On each UNIX physical node, type

hostid

from a system prompt and record the value.

For example: l

# hostid

84f8c879

On each Windows physical node: a. Connect to the NetWorker virtual server by using NMC.

b. In the Configuration window, select Licensing.

c. Right-click one of the listed licenses and select Properties.

d. Record the value in the hostid attribute.

e. Move the NetWorker resource group to each cluster node then repeat step a on page 64 through to step d on page 64

.

2. Log in to the system that runs the NetWorker virtual server and create the hostids file in the shared /nsr/res/ directory on UNIX or the share

NetWorker_install_path\nsr\res directory on Windows.

3. Specify the hostid of each cluster node in this file, separated by a colon (:).

For example:

12345678:87654321

4. Restart the NetWorker virtual server: a. Take the NetWorker application offline in the cluster.

Configuring Backup and Recovery

Setting NetWorker environment variables in a cluster

In a UNIX cluster, specify environment variables for a highly-available NetWorker server in the global /nsr/nsrrc file. The NetWorker Administration Guide describes how to use the /nsr/nsrrc file.

To define environment variables for the cluster-aware or stand-alone UNIX NetWorker host, modify or create the /nsr/nsrrc file in the local /nsr directory.

Limiting NetWorker server access to a client

By default, any NetWorker server can back up a NetWorker host and perform a directed recover to any NetWorker host. Use the servers files on a NetWorker host to limit

NetWorker server access.

A highly available NetWorker or server or cluster-aware client uses multiple servers files.

To limit NetWorker server access to a cluster node, you must create and edit these servers files: l l

Global servers file, located on the shared drive.

Local servers file on for each physical cluster node.

A stand-alone NetWorker application on a cluster node uses one servers file, located in the /nsr/res/servers on UNIX or theNetWorker_installation_path

\nsr\res on Windows.

To limit NetWorker server access to a cluster node:

Procedure

1. For a highly available NetWorker server or cluster-aware NetWorker client, take the

NetWorker virtual server offline on the active cluster node: l l

For AutoStart, use the AutoStart Console to take the NetWorker virtual server offline.

For HACMP/PowerHA, type:

3. On each physical node, edit or create the servers file: l

UNIX: /nsr/res/servers l

Windows: NetWorker_installation_path\nsr\res\servers

4. Specify the shortname and FDQN for each NetWorker server, one per line, that requires access to the NetWorker host.

When the NetWorker server is highly available: a. Add an entry for the NetWorker logical or virtual hostname first.

b. Add entries for each physical host

For example: clus_vir1 clus_vir1.emc.com

clus_phys1 clus_phys1.emc.com

clus_phys2 clus_phys2.emc.com

When the servers file does not contain any hosts, any NetWorker server can back up or perform a directed recovery to the host.

5. On the node with access to the shared disk, edit the global servers file.

Note

Ensure the hostnames defined in the global servers file are the same as the local servers file on each physical node.

6. For UNIX only, edit the NetWorker boot-time startup file, /etc/init.d/networker and delete any nsrexecd -s arguments that exist.

For example, when the /etc/init.d/networker contains the following entry: nsrexecd -s venus -s mars

Modify the file so the entry appears as: nsrexecd

7. Start the NetWorker daemons on each node.

8. For a highly available NetWorker host only, bring the NetWorker application online: l l

Configuring the NetWorker virtual server

This section only applies to a highly-available NetWorker server and describes how to configure the NetWorker virtual server and how to backup the shared disk.

NetWorker supports the use of multiple IP address for a resource group (resource service for MC/ServiceGuard). However, use only one of these IP addresses to configure the virtual client resource. The name of the NetWorker Client resource can be the short name, the FQDN corresponding to the IP address, or the IP address.

For example: resgrp1 is a resource group defined in a cluster and there are two IP resources defined in the group, IP1 and IP2 . If the IP address for IP1 is defined as a

NetWorker Client resource, then all shared paths in resgrp1 are saved under the IP address for IP1 index.

To configure the NetWorker virtual server:

Procedure

1. Use NMC to connect to the NetWorker virtual server.

2. In the Configuration window, right-click the NetWorker server and select Properties.

3. In the Administrator attribute, specify the root user account for each UNIX physical node. For each Windows physical node, specify the administrator and the system account for each Windows physical node.

For example:

UNIX physical nodes: [email protected]clus_phys1 [email protected]clus_phys2

Windows physical nodes: [email protected]clus_phys1 [email protected]clus_phys1 [email protected]clus_phys2 [email protected]clus_phys2

4. Click OK.

5. For NetWorker servers configured to use the lockbox only: a. In the left navigation pane, select Clients.

b. Right-click the client resource for the NetWorker virtual service and select Modify

Client Properties.

c. On the Globals (2 of 2) tab specify the name of each cluster node in the Remote

Access field.

l

For UNIX cluster nodes, specify the name of the host that appears when you use the hostname command.

l

For Windows cluster nodes, use the full computer name that appears in the

Control Panel

Creating a client resource for virtual client backups

This section describes how to create a client resource on a NetWorker server to back up a shared disk or Cluster Shared Volume (CSV), including deduplication-enabled CSV. These steps apply to cluster-aware clients and the NetWorker virtual server.

Procedure

1. Connect to the NetWorker server by using NMC. For a highly available NetWorker server, connect by using the virtual node name.

2. Create a Group resource to back up the cluster node or select an existing group. To ensure that backups for the virtual node restart when a NetWorker server failover occurs, enable the Autorestart attribute and disable the Manual Restart option.

Creating client resources for physical node backups

69

Configuring Backup and Recovery

3. Create a client resource for the virtual node, or edit the Client resource that NetWorker automatically creates for a NetWorker virtual server.

For Microsoft Failover Cluster, ensure that you configure a network name resource for the virtual client and that you add the resource to the resource group that contains the disks for backup. The full name of the network name resource should match the name of the NetWorker client resource or one of its aliases.

4. Specify the save set to backup in the Save set field. To back up: l l

All of the shared drives and CSVs that a virtual client owns, specify All.

A single drive volume of shared disk that a virtual client owns, specify the drive volume letter.

For example, to backup a single drive volume, specify

G:\

.

To backup a single CSV, specify C:\clusterstorage\volumeX, where X is the volume number, and C: is the system drive.

Note

If you specify the subdirectory of a deduplicated CSV volume, except in the case where the subdirectory is the root of a mount point, then NetWorker creates an unoptimized data deduplication backup .

5. For HACMP only, add the boot adapter name in the Aliases attribute.

6. On the Globals(1 of 2) tab, in the Remote Access field, specify the root user account for each UNIX physical node or the system account for each Windows physical node within the cluster.

For UNIX physical nodes: [email protected]clus_phys1 [email protected]clus_phys2

For Windows physical nodes: [email protected]clus_phys1 [email protected]clus_phys2

7. On the Apps and Modules tab, in the Application Information field, specify environment variables, as required.

l

For Snapshot Management backups only, use the NSR_PS_SHARED_DIR variable to specify the share directory. For example:

NSR_PS_SHARED_DIR=P:\share l

The NetWorker Snapshot Management Integration Guide describes how to configure

Snapshot backups.

For Windows Server 2012 and Windows 2012 R2 CSV and deduplicated CSV backups only:

As part of a deduplicated CSV backup, the preferred node attempts to move ownership of the CSV volume to itself. If the ownership move succeeds, then

NetWorker performs a backup locally. If the ownership move fails, then NetWorker performs the backup over SMB. When the CSV ownership moves, NetWorker restores the ownership ito the original node after the backup completes.

You can optionally specify the preferred cluster node to perform the backup. To specify the preferred server, use the NetWorker client Preferred Server Order List

(PSOL) variable NSR_CSV_PSOL .

EMC NetWorker Cluster 8.2 SP1 Integration Guide

Configuring Backup and Recovery

When you do not specify a PSOL NetWorker performs the backup by using the

Current Host Server node (virtual node).

Review the following information before you specify a PSOL: n n

The save.exe process uses the first available server in the list to initiate the

CSV backup. The first node that is available and responds becomes the preferred backup host. If none of the specified nodes in the PSOL are available, then NetWorker attempts the backup on the Current Host Server node.

The Remote access list attribute on the NetWorker client must contain the identified cluster nodes.

n

Use the NetBIOS name when you specify the node names. You cannot specify the IP address or FQDN of the node.

To specify the PSOL, include a key/value pair in the client resource Application information attribute. Specify the key/value pair in the following format:

NSR_CSV_PSOL=MachineName1,MachineName2,MachineName3...

For example, physical node clus_phys2 owns the cluster resources for virtual node clus_vir1 . By default, clus_vir1 runs the backup request. To offload operations, define clus_phy1 as the preferred node to start the save operation. If clus_phy1 is unavailable, then NetWorker should attempt to use clus_phy2 to start the save operation.

The NSR_CSV_PSOL variable in the clus_vir1 client resource is set to:

NSR_CSV_PSOL=clus_phy1,clus_phy2

When a physical node performs the backup, NetWorker saves the backup information to the client file index of the virtual client resource. When you recover the CSV backup, specify clus_vir1 as the source client.

8. For deduplicated CSV backups only, to configure an unoptimized deduplication backup, specify VSS:NSR_DEDUP_NON_OPTIMIZED=yes in the Save operations attribute.

9. Define the remaining attributes in the Client properties window, as required, and then click OK.

Configuring a backup device for the NetWorker virtual server

The NetWorker virtual server requires a local backup device to save the bootstrap and the server indexes. To ensures that the device is always available, configure a device that belongs to the NetWorker virtual server and is shared between the physical nodes.

Procedure

1. Edit the properties of the client resource for the NetWorker virtual server by using

NMC.

2. Select Globals (2 of 2).

3. In the Storage nodes attribute, specify the hostnames of each physical cluster node followed by nsrserverhost.

Configuring a backup device for the NetWorker virtual server

71

Configuring Backup and Recovery

Note

MSFCS does not support shared tapes. You cannot configure the NetWorker virtual server with tape devices connected to a shared bus. MSFCS supports disk devices connected to a shared bus. EMC recommends that you do not use file type devices connected to a shared bus.

Configuring a virtual client to back up to a local storage node

By default, NetWorker sends the data from a virtual client to the first storage node listed in the Storage Nodes attribute in the virtual client resource.

Use the keyword curphyhost to direct virtual client backups to a storage node device on the physical host that currently owns the virtual client.

The curphyhost keyword is only applicable to virtual clients. Do not specify this keyword in the clone storage nodes attribute in the Storage node resource or to the client resource of a NetWorker virtual server. This can cause unexpected behavior. For example,

NetWorker might write the bootstrap and index backups to the local storage node for the virtual clients, instead of a local device on the NetWorker virtual server.

Note

If you enable the Autoselect storage node attribute in the client resource, then NetWorker will override the curphyhost setting for the client. The NetWorker Administrators Guide provides more information about the Autoselect storage node attribute.

For example, consider a two-node cluster where: l l

Nodes A and B are the two physical nodes in the cluster.

The virtual client is saturn, which can reside on Node A or fail over to Node B.

During a backup without curphyhost listed in the Storage Nodes attribute for the virtual client, NetWorker directs the backup data to the remote device (rd=) on Node

A. When saturn fails over to Node B and a backup for saturn starts, NetWorker still directs the backup data to the remote device (rd=) on Node A.

When you specify curphyhost first in the Storage Nodes attribute for saturn, if saturn fails over to Node B and a backup of saturn starts, NetWorker directs the backup data to the remote device (rd=) on Node B. This action takes place because, after the failover, saturn resides on Node B—the current physical host.

To use curphyhost :

Procedure

1. Edit the properties of the virtual client resource in NMC.

2. Select Globals (2 of 2).

3. In the Storage nodes attribute, add the curphyhost keyword.

Performing manual backups of a cluster node

You can perform manual backups of the physical or virtual nodes in a cluster from the command prompt on UNIX and Windows or from the NetWorker User GUI, on Windows only.

This section describes how to configure NetWorker to allow a non-root or nonadministrator account perform manual backups and how to perform a manual backup.

72

EMC NetWorker Cluster 8.2 SP1 Integration Guide

Configuring Backup and Recovery

Configuring manual backups for non-root or non-administrator users

The backup operation uses the lcmap script to query the cluster and determine path ownership. When you perform a manual backup with a non-root account on UNIX or a non-administrator account on Windows, NetWorker cannot determine path ownership information. As a result, NetWorker writes the backup information to the client file index of the physical node that owns the file system instead of the client file index for the virtual node .

This sections describes how to configure each supported operating system to allow the lcmap script to query the cluster and determine path ownership for non-root or nonadministrator users.

Using non-root accounts on AutoStart for UNIX

Before you perform a manual backup of data from a virtual cluster client with non-root privileges on AutoStart for UNIX, use the ftconsole program to add non-root users to the security access list for the FT domain.

Using non-root accounts on HP MC/ServiceGuard

Before you perform a manual backup of data from a virtual cluster client with non-root privileges on HP MC/ServiceGuard, perform one of the following tasks: l

On each node in the cluster, ensure that the .rhosts file in the home directory of the non-root account includes the hostname of each cluster node. For example: l nodeA nodeB

As the root user on each node in the cluster, edit or create the /etc/cmcluster/ cmclnodelist file and add the following information to the file: nodeA user_name nodeB user_name

Note

If the cmclnodelist file exists, the cluster software ignores any .rhosts file.

Using non-administrator accounts on MSFCS

Before you perform a manual backup of data from a virtual cluster client with nonadministrator privileges on MSFCS, modify the security descriptor properties on the cluster so that the user can access the cluster resources.

For example:

Cluster ClusterName/prop "security descriptor"=DOMAIN

\USER ,grant,f:security

Using non-root accounts on VCS for UNIX

When you perform a manual backup of a physical or virtual cluster client in VCS as a nonroot user, the operating system might prompt you for a password.

To avoid the password prompt: l l

In VCS 4.0, set the AllowNativeCliUsers attribute to 1.

In VCS version 4.1 or later, use the VCS halogin command to store authentication information.

Configuring manual backups for non-root or non-administrator users

73

Configuring Backup and Recovery

Note

For information on how to set up VCS authentication, see the VCS documentation.

Using non-administrator accounts on VCS for Windows

For VCS 6.0 on Windows 2008 and Windows 2008 R2, to perform a backup you must start the NetWorker User application or command prompt window, as an administrator.

For example: l l

To start a backup operation from the NetWorker User application: Right-click the

NetWorker User application and select Run as Administrator.

To start a backup operation from the command prompt, right-click the command prompt application and select Run as Administrator.

Performing manual backups from the command prompt

To perform a manual backup of a virtual or physical node, use the save command.

For example: save -c client save_set where: l l client is the virtual hostname to back up shared disk data or the physical node hostname to back up data that is local to the node on which you run the save command.

save_set specifies the path to the backup data.

Performing manual backups from NetWorker User

You can use the NetWorker User program on a Windows physical node to back up shared or local data.

To back up shared data, open NetWorker User on the active physical node. While

NetWorker User on a Windows 2003 passive node displays the shared drives and VSS

SYSTEM save sets, when you attempt to back up the shared drives, error messages similar to the following appear:

77259:winworkr: VSS reports adding volume [shared_drive] to snapshot set failed for both hardware/software provider.

7281:winworkr: VSS snapshot failed with error 0x80042308 -- The specified object does not exist..

7284:winworkr: Networker will save the files without the snapshot.

84687:winworkr: Unable to get volume information of file system

EMC NetWorker Cluster 8.2 SP1 Integration Guide

Configuring Backup and Recovery l

No matching devices found when backing up to HACMP devices on page 76

RAP error: Unable to extract resource info for client

This message appears when the NetWorker server fails to back up a virtual cluster client because a NetWorker client resources does not exist for each physical node.

To resolve this issue, create a client resource for each physical node that is allowed to own the virtual cluster client and then start the backup.

File systems omitted during a scheduled save

In a cluster environment, the NetWorker software must distinguish between: l

File systems associated with a physical client.

l

File systems managed by a resource group (a virtual client).

To distinguish between these types of file system, NetWorker uses a criteria called the path-ownership rules. These rules determine which client file index should contain the information about a backup save set. By default, when a conflict in the path-ownership rules occurs, the NetWorker software does not: l

Back up scheduled save sets, which prevents a virtual NetWorker client from writing save set information to multiple client file indexes.

l

Consider there to be a match between the client that owns the file system and the client resource configured to backup the file system.

The following conditions cause NetWorker to omit a file system backup during a scheduled save: l

The Save set attribute for a physical client resource contains a file system owned by a virtual client.

l

The Save set attribute for a virtual Client resource contains a file system owned by a physical client.

Resolve this issue in one of the following ways: l l

Correct the save set attribute for the client on page 75

Override default path-ownership rules on page 75

Correct the save set attribute for the client

Configure the NetWorker client to only back up the file systems that the client owns.

1. Use the savegrp command to check the NetWorker path-ownership rules and display the list of filesystems owned by the client: savegrp -p -c client_name

2. Modify the Save set attribute for the client to contain only the file systems that the client owns.

Override default path-ownership rules

To force NetWorker to back up file systems that a client does not own, you can create the pathownerignore file in the NetWorker bin directory on the client. This file causes

RAP error: Unable to extract resource info for client

75

Configuring Backup and Recovery

NetWorker to ignore default path-ownership rules and write information about the file system save set to the client file index of the correct owner.

Note

Use the mminfo command to confirm that the backup information saves to the correct client file index. By design, the NMC server Group Details window and the Savegroup completion report state that the backup corresponds to the physical client where you configured the save set.

File system backup information written to the wrong client file index

When the pathownerignore file exists on a client at the time of a backup, NetWorker will back up save sets that a client does not own but writes information about the backup save set to the client file index of the host that owns the file system.

To determine which client file index will contain save set information, run a test probe with the verbose option set. For example: savegrp -pv -c client_name group_name where: l l client_name is the name of the cluster client.

group_name is the name of a group that contains the client backup.

To force NetWorker to write the save set information to the client that does not own the file system, perform one of the following tasks: l l l

For a manual save operation, use the -c option with the save command to specify the name of the client with the save set information.

For a scheduled save operation, to force NetWorker to the save set information to write save set information to the index of the client that backs up the save set:

1. Edit the properties of the client in NMC.

2. Select the Apps & Module tab.

3. In the Backup command attribute, specify the save command with the name of the client to receive the save set information: save -c client_name

Note

Use the mminfo command to confirm that the backup information saves to the correct client file index. By design, the NMC server Group Details window and the Savegrp completion report state that the backup corresponds to the physical client where you configured the save set.

No matching devices found when backing up to HACMP devices

This error message appears when backups to devices attached to an AIX HACMP cluster fail because the physical node name is not configured with an IP address that is attached to the primary NIC.

To resolve this issue, configure the physical node IP address on primary NIC.

Recovering data

This section describes how to recover data from shared disks that belong to a virtual client.

Note

The steps to recover data that originated on a private disk on a physical cluster client are the same as when you recover data from a host that is not part of a cluster. The NetWorker

Administrators Guide information.

provides more information. To recover Windows clusters, the chapter

Windows Bare Metal Recovery (BMR) in the NetWorker Administrators Guide provides more

To recover data backed up from a shared disk that belongs to a virtual client:

Procedure

1. Ensure that you have correctly configured remote access to the virtual client: a. Edit the properties of the virtual client resource in NMC.

b. On the Globals (2 of 2) tab, ensure that the Remote Access attribute contains an entry for the root or Administrator user for each physical cluster node.

2. To recover a CSV backup for a client that uses the NSR_CSV_PSOL variable, ensure that the system account for each host in the preferred server order list is a member of the NetWorker Operators User Group.

For example, if you configure the virtual node client resource that specifies the CSV volumes with the following variable: NSR_CSV_PSOL=clu_virt1, clu_virt2 , specify the following users in the NetWorker Operators User Group: [email protected]clu_virt1 [email protected]_virt2

3. Mount the file systems of the virtual client.

4. Recover the data.

l l

When you use the NetWorker User program on Windows, the source client is the virtual client.

When you perform a command line recovery, use the recover command with the -c option to specify the name of the client you are attempting to recover. For example: recover -s server_name -c virtual_client

Note

The -c virtual_client is optional when you run the recover command from the global file system that the virtual client owns. The recover man page or the EMC NetWorker

Command Reference Guide provide information. To recover data from a VCS 6.0 on

Windows 2008 and Windows 2008 R2 you must also start the NetWorker User program or command prompt window, as administrator. To start a recover operation from the NetWorker User application, right-click on the NetWorker User application and select Run as Administrator.

To start a recover operation from the command prompt, right-click on the command prompt application and select Run as Administrator.

Recovering data

77

Configuring Backup and Recovery

Configuring a virtual client to recover from a local storage node

During a recover operation of virtual client data, NetWorker attempts to mount the required volume in a device on the first storage node listed in the Recovery Storage

Nodes attribute in the virtual client resource.

Use the keyword curphyhost to instruct a virtual client recovery to mount the required volume in a storage node device on the physical host that owns the virtual client.

Note

The curphyhost keyword only applies to virtual clients. Do not specify this keyword in the clone storage nodes attribute in the Storage node resource or to the client resource of the

NetWorker virtual server. This can cause unexpected behavior, for example, the

NetWorker software writes the bootstrap and index backups to the local storage node for the virtual clients, instead of a local device on the NetWorker virtual server.

The following restrictions apply when you configure the recovery of virtual client data from a local storage node: l l l

Ensure that there are no hosts or machines named curphyhost on the network.

Do not specify curphyhost in the Clone storage nodes attribute of a virtual client storage node resource.

Do not apply the curphyhost keyword to the Storage nodes attribute or the Recover

Storage Nodes attribute of the virtual server's Client resource.

To configure the virtual client to recover data from a local storage node:

Procedure

1. Edit the properties of the virtual client resource in NMC.

2. In the Globals (2 of 2) tab, in the Storage nodes attribute or the Recover storage nodes attribute, add the curphyhost keyword. Position the keyword in the list based on the required priority. The keyword at the top of the list has the highest priority.

Ensure that this keyword is not the only keyword in the list.

Troubleshooting recovery

This section provides resolutions to issues that you may encounter when recovering data from a cluster node backup.

NSR server ‘ nw_server_name’: client ‘virtual_hostname’ is not properly configured on the NetWorker Server

This message appears when you attempt to recover data from the physical node of a highly available NetWorker server that was backed up by a NetWorker server that is external to the cluster. To resolve this issue, create a client resource for the highly available virtual NetWorker server on the external NetWorker server and retry the recover operation.

F

failover A means of ensuring application availability by relocating resources in the event of a hardware or software failure. Two-node failover capability allows operations to switch from one cluster node to the other. Failover capability can also be used as a resource management tool.

failover cluster Windows high-availability clusters, also known as HA clusters or failover clusters, are groups of computers that support server applications that can be reliably utilized with a minimum of down-time. They operate by harnessing redundant computers in groups or clusters that provide continued service when system components fail.

G

group Client computer or group of clients that are configured to back up files during a NetWorker scheduled backup, according to a single designated schedule or set of conditions.

H

Highly available application

An application that is installed in a cluster environment and configured for failover capability. On an MC/ServiceGuard cluster this is called a highly-available package.

Highly available package An application that is installed in a HP MC/ServiceGuard cluster environment and configured for failover capability.

host Computer on a network.

host ID Eight-character alphanumeric number that uniquely identifies a computer.

hostname Name or address of a physical or virtual host computer that is connected to a network.

L

license key Combination of an enabler code and authorization code for a specific product release to permanently enable its use. Also called an activation key.

M

node

A physical computer that is a member of a cluster. See physical client

node name

The HACMP/PowerHA for AIX defined name for a physical node. See physical client

P

pathname Set of instructions to the operating system for accessing a file. An absolute pathname indicates how to find a file starting from the root directory and working down the directory tree. A relative pathname indicates how to find a file starting from the current location.

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.

private disk A local disk on a cluster node. A private disk is not available to other nodes within the cluster.

R

recover To restore data files from a backup volume to a client disk and apply transactional (redo) logs to the data to make it consistent with a given point in time.

remote device 1. Storage device that is attached to a storage node that is separate from the NetWorker server.

2. Storage device located at an offsite location that stores a copy of data from a primary storage device for disaster recovery.

resource Software component that describes details of the NetWorker server or its clients. Clients, devices, schedules, groups, and policies are all NetWorker resources. Each resource has configurable attributes that define its properties.

EMC NetWorker Cluster 8.2 SP1 Integration Guide

Glossary resource database NetWorker database of information about each configured resource.

resource group

(application service)

The AutoStart defined name for a virtual server. See

virtual server

S

save NetWorker command that backs up client files to backup media volumes and makes data entries in the online index.

save set Group of files or a filesystem that has been backed up on storage media by using the

NetWorker software.

scheduled backup Type of backup that is configured to start automatically at a specified time for a group of one or more NetWorker clients. A scheduled backup generates a bootstrap save set.

service address The address used by highly-available services in an HACMP/PowerHA for AIX environment.

shared disk A disk that is shared by the cluster nodes.

stand-alone server A NetWorker server that is running within a cluster, but not configured as a highly-available application. A stand-alone server does not have failover capability.

storage device

See device

storage node Storage device physically attached to a computer other than the NetWorker server, whose backup operations are administered from the controlling NetWorker server.

V

virtual client A NetWorker Client resource that backs up data that belongs to a highly-available service or application within a cluster. Virtual clients can fail over from one cluster node to another. For HACMP/PowerHA for unix the virtual client is 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.

virtual server A NetWorker server configured to run as a highly-available application. A virtual server can fail over from one cluster node to another.
