I have Netbackup Enterprise Server 5.1
Sun V440 Server, Solaris 8, QLogic QLA2340 fibre card
Overland NEO 2000 library with FCO card
2x HP Ultrium 2 drives.
Some labels of the form AWGxxxL1
Trying to perform a backup, NetBackup (tldd) works it's way along the library trying and rejecting each tape in each drive. The error is that the tape is Unmountable. I can see the tape in the drive, then about 10 minutes after it is put there, a timeout occurs and the tape is rejected. There is one tape that has no label (there are others), this one tape worked and I backed up the whole server onto it, but it is rejected when I try a test restore.
I have searched Google and Veritas with each of the errors from /var/adm/messages and bptm log but have found nothing.
Clues please! Where do I go next.
Have tried changing settings in st.con, recreating /dev/rmt entries, mounted a tape manually using robtest and performed a server backup with ufsdump which worked.
I have found articles that suggest this may be related to:
The tape labels.
The licence for the library based drives.
The media (They are LTO2 tapes and LTO2 drivers), media all brand new.
