You are not alone....
DLT7000 Tape System Product Manual p.5-56 contains a list of
TapeAlert Flags, Severity Levels, and Meanings for LOG SENSE
command. There are 9 flags, and 6 of them correspond to
cleaning requests. 3 of them have Severity Level Critical
and 3 just Warnings. I think NetBackup ignores Warnings
and taking care of Critical errors, becous I've seen NetBackup
cleaning a tape drive.
You can ignore them too ....
I am checking my library every day and clean a tape drive
if I see a cleaning request on a front panel.
Thanks,
Andrew
