    Hi 114 

    This is not unexpected. In clustered mode NetBackup operates as active and standby. There are various directories that are configured to follow the active node. The catalog is the primary one, but also included is the var/global directory which among other things contains the device_mapping.txt file. 

    It is more usual and better practice to run (most of) the commands from the active node as the standby node will be missing important items.

    Cheers

      Hi David,

      A planned switch over activity in recent time.

      Should we  need to logged the case with Veritas OEM or with IBM? What should be the POA... can you suggest.

        HI 114 

        You don't mention whether you are using VCS or PowerHA for the clustering. Either which way, you should not need to open a case to fail over to the standby node. This should be a relatively normal part of operations. I would suggest you  do have someone on hand that understands the clustering technology in use (and have the support details handy just in case - especially if you have not done this often).

        As an aside, you indicate (in the tags) you are running on AIX and 8.1.2 - this is not a supported configuration (AIX server support finished with 8.1.1). If you are running your master server on AIX, then I would suggest to start planning for how you will migrate away from this platform (to allow you to upgrade). The clustering of the master server will complicate anything you want to do, so better to commence thinking about this now. I would suggest calling your local Veritas account team to help provide some possible solutions. 

        Cheers
