Hello . . . .

We learned something about 3584 libs yesterday.  This is probably old
stuff to most of you, but  I thought I'd mention it anyway.

Over the weekend we had a tape stick in a drive (3592).  TSM
detected the problem and put the path offline.  We called IBM
which replaced the drive.  The tape was ok so IBM stuck the tape back
in the 3584 CAP door and the lib moved it into a slot.

Somewhere in here TSM  threw the expected ANR8358E
stating that the lib should be audited.  This is what we normally
did - wait till the evening, take all the paths offline, the run a audit.

Today we did something different.  I checked a report from before
the problem and saw that the element address of the vol was 2051
before the problem.  Checking the 3584 Specialist interface, I saw
that the lib had put the tape back in that same slot - 2051.  There
_are_ other open slots, so the lib decided to put the vol back in the
slot where it belonged!  I DIDN'T KNOW THE 3584 WOULD DO THIS!
I always figured a tape put back into the lib like this would end up
in some random open slot necessitating an audit - apparently not.

We fired up a movedata on the tape which worked just fine.  No
AUDIT was necessary.   Gee, should have checked this out
a long time ago!!!
