Hi
I am using a Neo 24 Tape library with an LTO-9 drive.
The old one (Tandberg) broke recently and was replaced with a different
one. Then the backups with Bacula worked fine for some time. Now I get
those errors (again):

libexec/bacula/make_catalog_backup.pl MyCatalog"

I do not know if this may be caused by Bacual or by the tape itself.
Vendor says I must clean, however, the library is set to "autoclean" and
a cleaning tape is available. I changed the cleaning tape to a new one,
manually cleaned twice and tried again to backup with identical
(errorous) result.
Any idea how to trace the problem to the tape or software? What to do?
Thank you.
Are you using an SCSI controller to drive things?
Have you replaced the cable, or at least made sure it's 100% perfect and
locked in and so on???
And checked the SCSI card is good?
I switched to fibre-channel a decade ago, no problems since.
Cheers,
