Installing NetBackup 7.7.1 on Red Hat 7.9

Hi,

I am migrating NetBackup 7.7.1 to new hardware and then planning to upgrade NetBackup.

I am planning to install Red Hat 7.9 on the new server. I am confused with Veritas SORT note: "Red Hat Enterprise Linux 7 Update 5 and later support began in NetBackup 7.7.3 ". Does that mean that NetBackup Master and Media servers will not work properly on RH 7.9 or NetBackup will not be supported if it's installed on RH 7.9?

Thank you

    What I would do:

    • Create new master and media servers with RH 7.9 (it unsupported but may work)
    • Copy everything from the old master/media server to the new platform. You will have to re-use the old master server name, so ensure the new environment host cannot resolve the live environment.
    • Do no move production load from old setup
    • Quick regression test that Netbackup on the net platform work (again make sure client and master/media server cannot resolve the "live" environment).
    • Test the upgrade to Netbackup 8.X / 9.X (it will not go smooth first time)
    • At the big day perform everything above again - except regression test. Sync IP and hostnames so new environment  takes over the old environments IP.
    • And if everything blows up during upgrade at the big day - you still have the original environment untouched.

    there is not information about redhat 7.9 in 7.7 compatibility list as end of support for 7.7.x start at 2019-05-05.
    The latest release for Redhat back then was 7.5 and was supported with 7.7.3.

    I guess that 7.7.1 will not play well with 7.9. You may have some chances to work with 7.7.3 if you upgrade netbackup.

    I suggest you to go with the later supported redhat

      Hi serg2002 

      I'd approach this a different way. 

      I would upgrade the existing master server to an intermediate version supported by my existing OS and also the new OS. This keeps everything in a supported configuration and if you run into trouble you will have a better support experience than attempting to run an unsupported configuration. Then once the migration is completed to the new hardware upgrade to my final version.

      Cheers
      David

        Hi David,
        Thank you for the reply
        That is a good option, I was thinking about it. But what confuses me is if anything goes wrong with upgrading the current old version, I can be in a big trouble. Old version will be ruined, and I am not sure if I get any support since I will upgrade from not supported version. And I will finally need to install and recover old version.
        I actually like Nicolai's idea of migrating the existing version to new hardware and upgrading it right away.
        Do you think if will not work? Thank you

      Hi Nicolai,
      Thank you for the answer. I would like to ask you more questions if you don't mind.
      - "Do no move production load from old setup". Do you mean do not run any backup jobs? All our backup jobs start at night time, so it should not be a problem.
      - "so ensure the new environment host cannot resolve the live environment." As I mentioned all backup jobs start at night, so I guess even if both old and new server will be online, client will still not try to contact backup server. Please correct me if I am missing anything.
      - "Quick regression test that Netbackup on the net platform work". I didn't understand that. What exactly did you mean? What needs to be tested? Just a quick test of basic NetBackup functionality? Is anything in particular I need to test to be sure NetBackup functioning properly? Our set up is pretty basic. One master server, one tape library, just standard backups from NFS shares, no NDMP, no attached storages.
      - "Test the upgrade to Netbackup 8.X / 9.X (it will not go smooth first time)" Why will it not go smooth?
      - I know about keeping the same hostname, but I think IP address can be different, correct?
      Thank you
