First thank you all for your help (Bill Mansfield too) I should have thought of some of your suggestions. Now ...
No, I had not tried taking the other drives offline. The drive was visible from AIX
and it was available from the 3494. The CE looked at the error logs from AIX and from
the library and saw no problems.
I finally decided to try just taking the drive offline to TSM and then back online to
TSM (upd dr3494 command) yesterday and then checked the summary log this morning. It
showed that the drive was now being used.
The drive was definitely online to TSM before this time (Jan 7 was the last status
change for the drive listed in the database table) - the drive looked good from AIX
and also from the library itself. We examined the logs on the library itself yesterday
(before I made the change) and it seemed to show that some mounts were taking place on
that drive. We are going to go over it with the CE to make sure. If mounts were taking
place on the drive, was TSM requesting them and then somehow not logging
it in the summary file? If TSM was not mounting the tapes, what was? As far as we know
nothing else should have been able to mount tapes on that drive. So although the
immediate problem is solved, I am concerned about the integrity of the TSM logs.
