Scalar 1000's were/are notorious for
this. Also the dreaded "Dropped Cartridge" error where the entire
library stops functioning because it thought it dropped a cart when nothing
is wrong.

One peculiar thing that happens to us (at least twice a year) with our
old
ADIC Scalar 1000:
- Monday morning I'll go and check Netbackup Admin Console and see hundreds
of
failed jobs...The reason: insufficient media.
- I then check the Scratch volume pool and indeed there is no media!
(when
there was plenty).
- I notice there are now LOTS of tapes marked as 'FROZEN" ( This can't
be...)
To make the long story short, it turns out the library's gripper has a
tape
stuck in it...and being unable to grab a tape from the slot, Netbackup
marks
it as "FROZEN" after "x" retries. Then it proceeds
with the next available
tape from the Scratch pool and the story repeats...You can imagine.
Best regards,
Jorge
