My experience is that if you put a tape in the slot belonging to the tape
that is in the drive that the library (any library)will freeze this tape.
The M1500 is working well if you left the slot of the tape in drive empty.
Be careful because the slot numbering is different to netbackup and the
library (netbackup start from 1 and the library starts from 0)

Subject: [Veritas-bu] NB tape handling during backup/duplication events
Hi All,
I have a query regarding NetBackup and its media management during
Duplication / Backup events using tape drives.
We have two LTO2 M1500 tape libraries from Quantum each with 2 x 12 tape
magazines and one drive.
We have one Master/Media server combo attached to these two libraries NB
5.0MP4
We have noticed that while duplication events are taking place, if we
require to add/remove tapes from the libraries and re-inventory them in
NetBackup media manager the tape that is in the drive is "forgotten" about,
so when it is finished with or another tape is requested NetBackup and the
M1500 get in a right tizzy as NetBackup no longer knows about the tape and
as such does not inform the library to remove it from the drive and place it
back in a magazine. The only way to get the library functioning properly
again is to manually move the tape to an empty slot in one of the magazines
using the tape move function of the M1500. This is most incontinent as we
have to wait for all duplication events to finish before we can remove the
magazines from the libraries and add/remove tapes as required.
Has anyone else had similar problems and how did you fix them?
Any help would be graciously received.
Best Regards,
Bill.
