About EMC Navisphere server software
The EMC server-based software listed below is available on Powerlink and on the server support CD that shipped with your storage system or your upgrade kit (for upgrading AX4-5 series or AX series systems to Navisphere Manager).
For information on the server software supported with your CLARiiON
® storage system and the minimum FLARE
®
version required, refer to Minimum
FLARE revision required for your storage system, page 4
Navisphere Storage System Initialization Utility
Navisphere Host Agent
Navisphere Server Utility
Admsnap Utility
Navisphere Command Line Interface (CLI)
About the Navisphere Storage System Initialization Utility
For Fibre Channel storage systems, use the Navisphere
® initialization utility to discover storage systems and set network parameters (IP address, subnet mask, and default gateway). In addition, for iSCSI storage systems with iSCSI data ports attached to Windows servers, use the utility to set network parameters for these ports.
For CX series storage systems, an authorized service provider must install and run the initialization utility.
You can run the initialization utility from the server support CD or you can install it on a server or other host such as a Navisphere off-array management station. The only requirement is that the host be connected to the same network subnet as the storage-system management ports.
About the Navisphere Host Agent
The host agent registers the server’s host bus adapter (HBA) with the attached storage system when the host agent service starts. This action
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
5
sends the initiator records for each HBA to the storage system. Initiator records are used to control access to storage-system data.
The agent can then retrieve information from the storage system automatically at startup or when requested by Navisphere Manager or CLI.
The host agent can also:
Send operating system drive mapping information to the attached
CLARiiON® storage systems.
Monitor storage-system events and notify personnel by email, page, or modem when any designated event occurs.
Retrieve LUN world wide name (WWN) and capacity information from Symmetrix® storage systems.
About the Navisphere Server Utility
The server utility allows you to perform the following functions:
Update server information to the storage system
— Lets you send the server name and IP address to the storage system and, if needed later on, allows you to update or view this data.
Verify server high availability (HA)
— Lets you determine if the server is configured for high availability (HA) by verifying that the server has at least one connection path to each storage-system
SP, and that PowerPath
® or some other failover software, such as
VMware native, DMP, PV Links, or HP native failover for 11iV3 is running. The utility does not detect any other native failover software, such as Sun StorEdge Traffic Manager or Linux native multipath (MPIO).
Use the snapshot feature (Navisphere Express only)
— On storage systems with Navisphere Express, you can start and stop a snapshot on the source server (server assigned to the source virtual disk or source LUN), or you can allow or remove access to the snapshot by the secondary server (server assigned to the snapshot).
On AX4–5 series storage systems with Navisphere Manager, you cannot use the server utility to manage snapshots. Instead, you must install and use the admsnap utility.
6
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
You can run the Navisphere Server Utility from the CD or you can install it on the servers that are connected to the storage system. We strongly recommend that you install the utility on each server that is connected to the storage system.
About the Admsnap Utility
The Admsnap Utility is an executable program that you can run interactively or with a script to manage SnapView
® clones and snapshots. The Admsnap Utility resides on the servers connected to the storage system with the SnapView driver installed.
Use admsnap commands to:
Scan for new storage devices
Make storage devices inaccessible to the server operating system
Flush cached data to disk
List current snapshot devices
Map and unmap to a SnapView session
Start and stop a SnapView session
If you upgraded your storage system to Navisphere Manager and want to manage snapshots, you must use the SnapView software and the Admsnap
Utility. For more information on SnapView and admsnap, refer to the
Navisphere Manager help and the EMC SnapView Command Line Interfaces
Reference.
About the Navisphere CLI
The CLI complements, or is an alternative to Manager. It provides a command line interface for storage-system management, including storage provisioning, status and configuration information retrieval, and control. You can use the CLI to automate management functions through shell scripts and batch files. For more information, refer to the
EMC Navisphere Command Line Interface (CLI) Reference Guide.

EMC CLARiiON Server Support Products for Linux Servers Installation Guide
Running the Navisphere Storage System Initialization Utility
You can start the storage system initialization utility from the server on which it is installed or from the server support CD. The storage system initialization utility has three methods for executing commands — a user interface (UI) version, a command line interface that can be scripted, or a text-based utility that cannot be scripted.
Before continuing, make sure that the storage system is powered up completely.
For storage-system initialization, connect the server from which you are running the utility and the storage system to the same network subnet. Once you have assigned an IP address to the storage system, the server and storage system can be on different subnets.
Starting the initialization utility on a Linux server
To start the text-based version of the utility, enter:
/opt/Navisphere/bin/naviinittoolcli
To start the command line version of the utility, enter:
/opt/Navisphere/bin/naviinittoolcli
and any of the command line
switches in Using the command line initialization utility, page 15.
Starting the initialization utility on a Linux server from the CD
To start the text-based or command line version of the initialization utility from the CD, do the following:
1. On the server, log in to the root account.
2. In the server’s drive, insert the server support CD, which shipped with the storage system or the upgrade kit (for AX4-5 series or AX series systems upgrading to Navisphere Manager).
3. From a console window, mount the CD-ROM drive by entering the following command:
mount /mnt/cdrom
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
13
4. Change to the CD-ROM directory by entering the following command:
cd /mnt/cdrom
5. Navigate to the Linux directory:
cd Linux
6. Depending on which version of the initialization utility you want to start and run from the CD, enter the appropriate command:
Text-based version — ./naviinittoolcli
Command line version — ./naviinittoolcli and any of the command
line switches in Using the command line initialization utility, page 15.
Using the text-based initialization utility
After you start the utility, it automatically scans the subnet for supported storage systems. When this storage-system discovery operation is complete, the utility lists, by hardware serial number, all uninitialized and initialized storage systems it found. The hardware serial number for CX4 series storage systems is on a hanging tag at the rear of the storage system.The hardware serial number for CX3 and
CX series storage systems is on a blue label located on the SPE chassis behind the front bezel.The hardware serial number for AX4-5 and AX series storage systems is on a blue label on the rear of the chassis.
If the storage system you are installing was not discovered, verify the cable connections between the storage system and the host running the utility.
Use the information in the “Storage-System Management Ports” worksheet from the storage-system configuration planning guide, planning worksheets document, or the administration worksheet, and follow the instructions on the screen to change the storage system’s name, to set the network parameters for the storage-system 10/100 management ports, and to set the storage system’s management user account settings.

Determining whether to install the host agent or server utility
Depending on your application needs, you can install the host agent, server utility, or both on an attached server.
If you want to install both applications, you must install version 6.22.20
or later of the server utility either before or after you install the host agent. The registration feature of the server utility will be disabled and the host agent will be used to register the server’s NICs or iSCSI
HBAs to the storage system.
Prior to version 6.22.20 of the server utility, you could not install the host agent and server utility on the same server. However, you could install them on different servers that are connected to the same storage system.
If you do not want to install both applications, but want to use some of the features available in the server utility, you can run the server utility from the server support CD.
If you have an AX4-5 series or AX series storage system running
Navisphere Express, you can install only the server utility. The host agent is supported only on CX4 series, CX3 series, CX series, AX4-5 series, and AX series storage systems running Navisphere Manager.
Table 3 describes the differences between the host agent and the server
utility on a server attached to a storage system.
Depending on the version of the server utility, some of the features listed in
may not be available.

EMC CLARiiON Server Support Products for Linux Servers Installation Guide
Requirements for the host agent, server utility, and CLI
To run the host agent, CLI, or server utility, your server must meet the following requirements:
Run a supported version of the Linux operating system.
For Fibre Channel connections, have the EMC CLARiiON supported HBA hardware and driver installed.
Be connected to at least one SP (two SPs for high availability) in each storage system either directly or through a switch or hub. Each
SP must have an IP connection.
For the host agent and CLI only - Be on a TCP/IP network connected to at least one SP (two SPs for high availability) in the storage system. The TCP/IP network connection allows the server to send
LUN mapping information to the storage system and it allows
Navisphere Manager or CLI to communicate with the storage system over the network.
Have a configured TCP/IP network connection to any remote hosts that you will use to manage the server’s storage systems, including: z z any server whose browser you will use to access Manager 6.X.
any Windows Server 2008, 2003, or Windows 2000 server running Storage Management Server software.
z any AIX, HP-UX, Linux, VMware ESX Server, NetWare, Solaris,
Windows Server 2003, or Windows 2000 server running the CLI.
If you want to use the CLI on the server to manage storage systems on a remote server, the server must be on a TCP/IP network connected to both the remote server and each SP in the remote server’s storage system. The remote server can be running AIX, HP-UX, Linux, Solaris, or the Windows operating system.

d. Enter the following command to install both the host agent and
CLI packages:
rpm -ivh naviagentcli.noarch.rpm
The system displays the word navigentcli and a series of pound (#) signs. When the installation is complete, the system prompt reappears.
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
e. If you installed the software from the server support CD, unmount the CD, and then remove the CD from the CD drive.
If the File Manager window is open to the /mnt/cdrom directory, you need to close this window first before attempting to unmount the CD.
6. Verify that Navisphere Agent and/or CLI are installed by using the
rpm -qa | grep navi
command.
Before you can use the host agent or CLI, you must modify the user login scripts and configure the host agent configuration file.
7. If you have a multihomed host (multiple NIC cards installed on the host), create an agentID.txt file to ensure that the agent finds the correct NIC card.
A multihomed host machine has multiple IP addresses connected to networks; it is physically connected to multiple data links that can be on the same or different networks. When you install Navisphere Host Agent on a multihomed host, the host agent, by default, binds to the first NIC in the host. If your host is multihomed, for the host agent to successfully register with the desired CLARiiON storage system, you need to configure the host agent to bind to a specific NIC. You do this by setting up an agentID.txt file.
a. Using a text editor that does not add special formatting, create or edit a file named agentID.txt (case sensitive) in either / (root) or in a directory of your choice.
b. Add the following two separate lines to the agentID.txt file, with no special formatting:
First line:
Fullyqualified hostname of the host
Second line:
IP address of the HBA/NIC port that you want Navisphere agent to use
For example, if your host is named host28 on the domain
mydomain.com
and your host contains two HBAs/NICs,
HBA1/NIC1 with IP address 192.111.222.2 and HBA2/NIC2
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
25
with IP address 192.111.222.3, and you want the host agent to use NIC 2, you would configure agentID.txt as follows:
host28.mydomain.com
192.111.222.3
The agentID.txt file should contain only these two lines, without any formatting. The first line should contain the hostname and the second line should contain the IP address of the HBA/NIC port as described above. Both lines should end with a carriage return. As a result, the cursor will be on a third line but this line should not contain any text.
c. Save the agentID.txt file.
d. If you created the agentID.txt file in a directory other than root, for host agent to restart after a system reboot using the correct path to the agentID.txt file, set the environment variable
EV_AGENTID_DIRECTORY
to point to the directory where you created agentID.txt.
e. If a HostIdFile.txt file is present in the directory shown for your operating system, delete or rename it. The HostIdFile.txt file is located in /var/log/HostIdFile.txt.
f.
Stop and then restart the host agent.
g. Once the host agent has restarted, verify that the host agent is using the IP address that is entered in the agentID.txt file. To do this, view the new HostIdFile.txt file. You should see the IP address that is entered in the agentID.txt file.
Installing the Navisphere CLI on a Linux server
EMC recommends that you install the most recent version of the
Navisphere CLI software that is appropriate for your configuration.
You can download the most recent version from the software download page on the Powerlink website (CX4 series, CX3 series, CX series, and
AX4-5 series) or on the storage-system support website (AX series).
You can also install the software from the server support CD (any storage system); however, the CD may not contain the most recent version for your configuration.
1. On the Linux server, log in to the root account.
2. At the command line prompt, look for any existing CLI by typing:
26

30
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
Configuring the Navisphere Host Agent
Before you can use the Navisphere CLI navicli register command to configure your storage system, you must make sure the host agent
configuration file includes a privileged user, as described in Adding
The pathname of the host agent configuration file is /etc/Navisphere/agent.con-
fig
.
If you are configuring a legacy storage system, refer to revision A10 of this guide.
A legacy system is an FC series storage system that is not running storage management server software.
Adding privileged users
If you will use Navisphere CLI to configure any storage system, the host agent configuration file must include an entry that defines the person who will issue the CLI commands as a privileged user.
To define a privileged user, add a local or remote privileged user by adding the appropriate entry below.
For a local user:
user
name
For a remote user:
user
name@hostname
where name is the person’s account name and hostname is the name of the remote server the person will be using.
The default host agent configuration file includes a user root entry.
Saving the host agent configuration file
1. Save the host agent configuration file.
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
31
2. If you have finished adding information to the host agent configuration file, stop and restart the host agent by entering the following commands:
/etc/init.d/naviagent stop
/etc/init.d/naviagent start
32
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
Using the event monitor configuration file
The Navisphere Host Agent can monitor storage-system events and take such action as sending email or paging you if specified events occur. The event monitor that ships with Navisphere Manager provides an interactive way to define these events and actions. If you do not have event monitor, you can still define such events and actions by editing the event monitor configuration file.
/etc/Navisphere/Navimon.cfg
The file is self-documenting; that is, text in it describes how to define events and the actions you want taken if the events occur. You can test the file after editing it using the Navisphere CLI command
responsetest
, as explained in the Navisphere Command Line Interface
Reference.
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
33
Running the Navisphere Host Agent
This section describes how to test the host agent connections and how to start and stop the host agent.
Starting and stopping the Navisphere Host Agent
The host agent starts automatically when you bring the server up to init level 3. When you first start the host agent, look at the system log for the server’s operating system to make sure the agent started and no device errors occurred. The system log is located in /var/log/messages.
When a storage system experiences heavy input/output traffic (that is, applications are using the storage system), information may not be reported to the host agent in a timely manner, resulting in the host agent taking several minutes to execute a storage-system management task. This behavior is most evident when one host agent is managing multiple storage systems. Also, if the
SP event log is large and the host agent configuration file is set up to read all events, it may take a few minutes for the host agent to start.
Starting the host agent
Log in as root and enter this command:
/etc/init.d/naviagent start
Stopping the host agent
Log in as root and enter this command:
/etc/init.d/naviagent stop
Testing the host agent connections
Before continuing, you should test the host agent connections as follows:
1. Start the host agent as described in Starting and stopping the
Navisphere Host Agent, page 34.
2. Look for any errors on the console and in the operating system log to make sure the agent started and no device errors occurred.
34
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
3. Verify that the host agent on the server can see the storage system as follows: a. Enter the following CLI command:
naviseccli
|navicli [-d device]| -h hostname port
-list -hba
You cannot specify both the –d switch and –h switch.
where:
[-d device] is the device name for the storage system (only supported with legacy systems).
-h
hostname is the IP address of the SP.
For each HBA in the server, a listing similar to the following will be displayed. For storage systems in a SAN (shared storage) environment, the listing includes HBAs in all connected hosts.
Information about each HBA:
HBA UID: 10:00:00:60:B0:3E:46:AC:10:00:00:60:B0:3E:46:AC
Server Name: siux134
Server IP Address: 128.221.208.134
HBA Model Description:
HBA Vendor Description:
HBA Device Driver Name:
Information about each port of this HBA:
SP Name: spa
HBA Devicename: sp0
Trusted: NO
Logged In: YES
Source ID: 1
Defined: YES
Initiator Type: 0
Storage Group Name:
Storage Group 134 b. In the listing, examine the information for each HBA installed in the host to verify the path from the HBA to the SP.
Host agent status and error logging
While the system is running, the operating system tracks information about host agent events and host agent errors, and places this information in log files on the server.
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
35
The host agent error log tracks information about the host agent’s startup, the host agent shutdown, and errors that might occur, such as the host agent’s inability to access a device in the configuration file. If problems occur, log files are a good place to start your troubleshooting.
Host agent events and errors are logged in /var/log/agent.log. System events are logged in /var/log/messages.

Using the Navisphere Server Utility
The Navisphere Server Utility allows you to perform the following functions:
Update server information on the storage system
Perform snapshot tasks (Navisphere Express only)
42
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
Generate a high-availablity report
Updating server information on the storage system
The Update Server Information option allows you to send information about the server to all connected storage systems. To update server information, select option 1 from the server utility’s Welcome screen, and follow the instructions on the utility.
Performing snapshot tasks
For information on using the snapshot tasks option, refer to the
Navisphere Express online help.
Generating a high-availability report
The Generate high availability report option (option 3) and the
naviserverutilcli hav
command determine if the server is configured for high availability by verifying that the server has at least one connection path to each storage-system SP, and that PowerPath or some other failover software, such as DMP, is running. The utility will not detect any other native failover software, such as Linux native multipath (MPIO).
After the verification, the utility generates a summary report and saves it to the server. If you issue the -upload switch with the
naviserverutilcli hav
command, the utility also sends the report to the specified storage system.
Generate a high-availability report to:
check the status of a server.
prepare for software installation on a storage system.
For AX4 systems only
— Use the -upload switch to upload the HA report to the storage system only if you will use the Navisphere Software Assistant to install new software. We strongly recommend that you use the Software
Assistant, and not the -ndu install command to update your software. The
-ndu install
command does not perform the same pre-installation validation checks as the Software Assistant. The Software Assistant is included in the
Navisphere Service Taskbar.
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
43
Checking the status of a server
To periodically check the high-availability status of a server, you can select option 3 from the server utility’s Welcome screen, and follow the instructions in the utility to generate a high-availability report, or issue the naviserverutilcli hav[-directory | -d outputdirectory] command.
where:
-directory | -d
outputdirectory
Specifies the directory to which you want to deposit the report on the server. This switch is required only if you are running the server utility from the CD. Otherwise the report is automatically saved to the Navisphere Server Utility installation directory.
If the server utility is installed on your server and you specify a directory, the directory you specify will override the server utility’s installation directory.
Preparing for software installation on a storage system
If you are generating a high-availability report as a prerequisite to updating storage-system software, you need to upload this report to the storage system prior to installing the software on the storage system.
To generate and upload an HA report, issue the following command from the directory in which you installed the utility:
naviserverutilcli hav -upload -ip
IPaddress |-h
IPaddress|network_name -user|-u username -password|-p
userpassword -scope|-s scopelevel -secfilepath securityfilepath
-port 443|2163
[-directory | -d outputdirectory] where:
44
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
-ip IPaddress
-h IPaddress |
network_name
-user | -u
username
-password | -p
userpassword
Specifies the IP address of an SP on the storage system to which you will upload the report. You cannot use this switch in conjunction with the -h switch.
Specifies the IP address or the network name of an SP on the storage system to which you will upload the report. You cannot use this switch in conjunction with the -ip switch.
Specifies the login name for the storage system. You must use this switch in conjunction with the -password | -p and -scope | -s switches. You
cannot use this switch in conjunction with the -secfilepath switch.
Specifies the password required for access to the storage system. You must use this switch in conjunction with the -user | -u and -scope | -s switches. You cannot use this switch in conjunction with the -secfilepath switch.
-scope | -s
scopelevel
-secfilepath
securityfilepath
Specifies the level of access this username and password has to the storage system: 0 = global; 1 = local; 2 = LDAP. You must use this switch in conjunction with the -user | -u and -password | -p switches. You
cannot use this switch in conjunction with the -secfilepath switch.
Searches the security file for the specified IP address. If the utility does not find the specified IP address, then the utility will use the default entry in the security file.
A security file is required to run this switch. For information on how to create a security file, refer to the EMC Navisphere Command Line (CLI)
Reference guide.
You cannot use this switch in conjunction with the -user | -u, -password |
-p , and -scope | -s switches.
-port 443 | 2163 Specifies the Navisphere Management Server port number. The default is 443.
-directory | -d
outputdirectory
Specifies the directory to which you want to deposit the report on the server. This switch is required only if you are running the server utility from the CD. Otherwise the report is automatically saved to the
Navisphere Server Utility installation directory.
If the server utility is installed on your server and you specify a directory, the directory you specify will override the server utility’s installation directory.
After uploading the HA report
In addition to running the server utility to validate server high availability, we strongly recommend that you perform the following manual checks.
EMC CLARiiON Server Support Products for Linux Servers Installation Guide
45
Verify support of software and hardware
— Make sure that you have verified that all software and hardware is supported according to the EMC E-Lab™ Interoperability Navigator and support matrices.
This tool does not verify that you are running supported switch firmware, nor that you are using redundant switches (recommended).
Upgrading storage–system software
— If you are about to perform a storage-system online software upgrade or you added an HBA, a
LUN, or changed connectivity (added a path or changed zoning): z Make sure that you have validated all software and hardware that are supported and interoperable according to EMC E-Lab
Interoperability Navigator and support matrices.
z Verify that all LUNs (virtual disks) that your servers will access during the upgrade are under path management software control. For servers running PowerPath and DMP, see the
Failover Software section on the Details tab of the report and locate these LUNs. If they are not in the list, the server will lose access to those LUNs during the software upgrade.
