Navisphere Host Agent For Linux

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 as follows:
 
NOTE:  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 specificNIC. 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 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
 
NOTE: The agentID.txt file should only contain 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 /etc/log/HostIdFile.txt.
 
f. Stop and then restart the host agent.
 
g. Once the host agent has restarted, verify that 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.
 
Modify user login scripts:
 
NOTE:  To use navicli commands at the root prompt without typing a leading ./ before the commands (for example, ./navicli getagent), you must modify the $PATH environment variable in the user login script as follows:
 
a. Add /opt/Navisphere/bin to $PATH:
 
PATH=$PATH:/opt/Navisphere/bin export PATH
 
NOTE:  To verify the path enter echo $PATH
 
b. Set the environment variable $PATH for all login sessions:
 
¿ For the user profile, edit $HOME/.bash_profile
 
¿ For the user startup script, edit $HOME/.bashrc
Start the Host Agent:
 
¿ If you are upgrading the Host Agent or CLI on an existing system, you are finished with the upgrade.
 
¿ If you are setting up a new server, enter the following command from the root account:
 
/etc/init.d/naviagent start
 
NOTE:  When you first start the Host Agent, look at the system log for the host¿s operating system to make sure the Host Agent started and no device errors occurred.  The system log is located in /var/log/messages.
