Migrating Netbackup from Solaris to Linux

Hello,

I am relatively new to the Netbackup world and I am working on migrating our Netbackup infra from Solaris (v10) to Linux (RHEL7). We were running Netbackup v7.6.0.2 before and I upgraded it to the latest version v7.7.3.

I had few questions before I proceed with the migration. I looked around for answers probably couldn’t find the exact answers for the below questions (or probably I didn’t search enough L).

We have 90TB of JBODs available to our media server (for staging the data written to tapes) and 14TB in our master server (for the catalog).

- Currently we use ZFS as a local filesystem and the data disks are in ZFS pool.

   So, in RHEL7 world what would be the recommended:

         - Local filesystem? (I believe XFS). I am thinking of creating local partitions in XFS.

         - Preferred software RAID (MDRAID or Megaraid or anything else)? I am planning to go with RAID 1.

- I will take a full Catalog backup before I start the migration and then attempt a restore after installing Netbackup 7.7.3 in Linux. Is that the right approach or is there a better way out for the migration?

Also, I believe this full catalog backup will hold a complete copy of my Policies/Storage Groups/Media pools/Tape Drive configuration etc. Right?

- [Little out of scope from Netbackup] After I migrate the servers to Linux, should I re-configure the tape drives as devices from the OS perspective?

Thanks for the help.

-Ram

    It's totally up to you

    You can use standard  LVM or md or whatever you like.

    Yes, this is the right way

    Yes

    Yes, if you had configured tape drive on Solaris server

      You need to plan the master and media server separately.
      Master server migration can be done using this TN: http://www.veritas.com/docs/000041077

      For the media server - best to ensure that all disk images are duplicated to tape and then expire everything on disk.
      Your choice of filesystem is not something I can give an opinion about.
      My personal preference would be Veritas Volume manager and Filesystem.
      Start with new DSU on new media server.
      See this TN for guidelines: http://www.veritas.com/docs/000041204

        Thanks for the response Marianne.

        I did go through that link for the master server upgrade before. I am yet to go through that Disaster Recovery doc for the procedure for the restoral.

        I did skim through that doc for the Media server upgrade and it does look straight forward, thanks J.

        And the handy netbackup links is also good, thanks J.

      I will go ahead with XFS.

      Okay, let me read through a bit more to get more clarity on this.

      Perfect thanks.

      >> Yes

      Thanks for the confirmation.

      Yes, I am looking for some information on how to do this on RHEL boxes. I am checking online for any documentation on this , in the meanwhile, please let me know if you have any insights.

        It's easier that on Solaris because you don't have to re-build st.conf file and NetBackup is able to see all tape drive just after installation. The only thing you might have to do is to delete drives (or paths if you use SSO) with Solaris path and run Device Configuration wizard or add all those drives from CLI.
