Subject: 2 3494 Tape libraries seem to have very different capacities.
Any ideas?


      We have 2 3494 tape libraries. One is local and the other is remote.
The local one (3494LOCAL) receives all the data from the nightly backups as
it gets migrated from disk. The remote one (3494REMOTE) is only used as the
target of backing up the 3494LOCAL storage pool which gets done everyday
during the day. 3494LOCAL has 577 library volumes in it. 3494REMOTE has 494
library volumes in it. Both tape libraries only have 3590K tapes in them.
      My problem is that 3494LOCAL has 62 scratch tapes available and
3494REMOTE has 207 scratch tapes in it. Reclamation runs daily and sets the
same percentage (57) for both libraries. How can there be such a huge
difference in the number of scratch tapes if both libraries should roughly
have the same amount of data? It's making me a little nervous that
3494REMOTE doesn't have the same data or something somewhere is going
wrong.
Any ideas?
Thanks,
John
