First of all, the expiration date seen with vmquery is not the expiration
date for NetBackup. The expiration date seen with vmquery is the
expiration date within Media Manager and it's probably empty because
you're probably not using this type of expiration in your environment.
This is the date that tells Media Manager the tape has been in your
rotation for x years and should not be considered "reliable" any more...
sort of like what max mounts value is for.
Assigned media that no longer contains valid backups can be caused by not
decommissioning a media server properly or rebuilding a media server and
not restoring it's MediaDB. Before turning a media server off you should
move all the media ID's from that media server to another one (or the
master, if it's also a media server) using bpmedia -movedb.
Not sure if that's your problem here. It's weird that the Media Contents
report shows an image that has not expired but the image catalog doesn't
know about it. Does the Media Contents report get this expiration
directly from the tape when it reads the tape or is it coming from
somewhere else? If it's coming from the tape, did you maybe bpexpdate
this image to expire it early and it's showing the date it would have
expired based on when it was written (that would explain why it's not in
your image catalog).
The available_media_report can be thrown off if it's ran when a media
server is unreachable (or decommissioned improperly as stated above) or if
all of the Storage Units for that media server have been removed. I can't
remember how it shows these. If you want to test to see if these
"orphaned" medias show up as FULL, you could stop the services on one of
your media servers and rerun the report and see if a large number of the
tapes change to FULL status.

Thank you, question to everyone. What can cause assigned media that no
longer contains valid backups? Why wouldn't NetBackup have taken care of
this itslef?
