I have seen reclaim change a tape to unavailable status when it
completes and there are still files left on the tape volume.  This is
done to prevent reclamation from going into a loop for a bad
tape.  Check the tape and see if it is unavailable.  If it is, I
think it should be safe to change it back to readwrite, based on what
you said the problem was.

They will be reclaimed the next time reclamation runs, since the volume
is readable again.
No further action required.

I'm wondering if any corrective action needs to be taken due to the
following condition.

ANR4936I Reclamation of storage pool TAPEPOOL5 has ended.
Files reclaimed: 1098621, Bytes reclaimed: 157994931645,
Files reconstructed: 16900, Unreadable files: 150.
(SESSION: 42033)

This is the first and last time I've ever found this condition. The only
diagnostic action taken was to do an 'audit vol' of the volume that
received the reclaimed data.

Root cause turned out to be several jammed tapes in the 3583 library and
a
bad gbic. Once the gbic was replaced and the tapes manually adjusted and
'audit library checkl=bar' was run then everything seems normal.

Running TSM server 5.3.1 on AIX 5.2 ML5 with 3583 libraries.
