Netbackup 6.5.5 on Linux (RedHat Enterprise Linux)

Just upgraded my master and media servers to Symantec (I still like the name Veritas) Netbackup 6.5.5.  Successfully update all my RHEL servers with no impact to operation.

Let me share with you what maybe the best way to upgrade:

From Netbackup 5.x to 6.5.5
------------------------------------

1. Temporary stop any backup job for the client.
2. Check the client OS version in Netbackup console. 
• RHEL 3 -- Linux 2.4
• RHEL 4, RHEL 5 -- Linux 2.6
3. Use the Netbackup Media or ISO (download from Symantec FileConnect).
4. Install the base package (Netbackup 6.5). 
5. Then download Netbackup 6.5.5.Get the packages here. 
6. Untar all packages into a single folder. Then run "NB_update.install". It will pickup all the packages that you have untar just now. Install base update first before agent.

From Netbackup 6.x to 6.5.5
-------------------------------------

1. Temporary stop any backup job for the client.
2. Check the client OS version in Netbackup console. You must select the right kernel and OS version else you will encounter installation failure.
3. Run this from your master server.
1. /usr/openv/netbackup/bin/install_client_files sftp hostname username
   
4. Just follow the procedure you see after you run the install_client_files.
5. Note: The procedure does not update database agent. You need to download the update database agent packages from Symantec website. Then manually update the agent.

Some advice

• Turn on all the log on Netbackup client. Create these directories in /usr/openv/netbackup/logs
• bpcd (communication process for daemon)
• bpbkar (log debug info)
• bphdb (database agent log)
• bpbrm (handle backup and restore request)
• bptm (tape) or bpdm (disk storage unit)

• Check the date for shared library (libobk.so) file in /usr/openv/netbackup/bin. It should be within year 2009.
• Do a /usr/openv/netbackup/bin/bpclntcmd -pn master_server
• Check if you have configure firewall access for Netbackup port
