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
