Hi there,

Some time ago we experienced a power failure that lasted long enough
to make us shut down our 3584 library. This was done gracefully, and
when the power came back we turned the library back on. The TSM server
was also gracefully shut down and turned back on.

After TSM came back, I did an AUDIT LIBRARY which exited with a failure;
two tapes which TSM thought were in the library, weren't (according to
the library) so TSM took them out of its inventory. The strange thing
was that the tapes were indeed in the library.

Some investigation revealed that the library was somehow "blind" to
tapes in the last row of the first and second column, but this only
happened after a library initialization due to a powerup or open/close
of the entire front door.

This happens with every tape I tried, so the labels aren't the problem.
A tape which is perfectly well recognized in any slot doesn't show up
in the lowest slot in column 1 and 2. The library doesn't detect anything
there, it'll also let you move a tape to a full slot using the control
panel. Of course, this results in an error (94 80: slot unexpectedly full).

IBM is already on this, and it's no big problem because I can easily work
around it by leaving the first row almost completely empty. This results
in the problematic slot not to be used, because our tape rotation isn't
that high.

I was interested if this symptom perhaps looks familiar to someone here.
We're on library code 5770, and the TSM symptoms are errors about slots
being unexpectedly full and TapeAlerts about the library inventory
being inconsistent.

Thanks,
