Re: [Veritas-bu] Need help with FAILOVER_RESTORE_MEDIA_SERVERS

Justin,
I think you are misinterpreting the parameter. It has nothing to do with how busy a server is... It's if the server is totally not available (offline).
From the SAG:
"Specifies automatic failover to another NetBackup server if a server is temporarily inaccessible for a restore."
The key word is "inaccessible".
If you need a temporary solution, look at bpmedia -movedb... you can "move" the server so that you can complete the restore, then move back.
I though I heard at one point that this whole media "ownership" thing was going to go away. I just don't know when. That way, if you kick off a restore, it sounds like it would try to use the original host, else, find one that is available so I can just get the restore done... In the short term, bpmedia is your bet option.
