I sync’d
our production NetBackup 5.1MP6 installation to a test server we have (normally
used for DR) and upgraded that to 6.5, then patched to 6.5.1. Everything worked
as documented, no problems were encountered other than one inconsitency that
NBCC caught (there was a frozen tape with expired images on it that it
complained about. We unfroze the tape, let the images expire, and it was fine
after that).
We have yet to upgrade our production environment, but we have a simple setup,
one master server that is also the media server, so it’s very
straightforward. Rollback plan involves breaking the root disk’s mirror
and snapshotting the netbackup volume (which is ZFS). Any problems and we boot
off the other side of the mirror and roll back the snapshot. However, if we’ve
written to tapes since ugprading, it becomes a bit more difficult…

Quick Q - when you realised the problems, were you able to
plan to REVERT the systems back ?
Simon
Revert back to 5.1? I realize now that there should have been a
plan to do that; Symantec reccomended it after hours of going nowhere but the
client didn't want to. And even if they did, what is the procedure for
doing this? _______________________________________________
