     Actually the RACK-1 COLUMN-A SLOT-1 is the lost tape slot so in such a
     situation the CE should place the tape in that slot, have the library
     set to INVENTORY INABLED and when the door is closed one of the first
     things the L12 does is check the lost tape slot and gets everything
     back in sync...

     Most of the time CE's tend to set INVENTORY DISABLED to speed things
     up, you can go to the control panel on the L12 and have the atl
     perform an inventory update, then do an "audit libr" within adsm to
     get things back in sync.

     NOOOOOOooooooo don't do a "delete vol xxx discard=yes"  ARGHhhhhh!

     Worst case is open the ATL, get the tape, either query the l12 db to
     find the tapes proper slot and put it there OR put it in the lost tape
     slot, then inventory the atl, then audit the library, then you might
     have to do a checkin libvol blahl blahvolser STATUS=PRIVATE blah blah
     even though the initial checkin was done with status=scratch IT IS NOW
     PRIVATE WITH DATA ON IT !  it will still roll back scratch when it
     empties.

     later,
         DWight

We have ADSM/6000 2.1.5.15 with an attached 3494-L12 Tape Subsystem.
We expect to upgrade the server to V3 versy soon.

During one recent episode where a tape drive was experiencing problems, a
tape
was stuck in the drive while the normal ADSM operation continued.  The tape
in the
drive did have data from prior migration processes.

Before the Tape was stuck in the drive the command "Query Libvolume Tapelib
TAPE01"
would show information about the tape being allocated Private.  "Query
Volume TAPE01"
reveals how much the tape is currently utilized.

During the drive outage, the Library Manager and drive was varied offline
from the SMIT-
DEVICES - ADSM DEVICES selection.  While the IBM CE repairs the drive, the
tape is
pulled straight from the drive and placed directly into the open slot in
the Library.  Upon the
restart of the 3494, an inventory is taken of all of the tapes in the
library.

After the drive outage, "Query Volume TAPE01" still shows the current tape
utilization. It is
just marked as unavailable.   The "Query Libvolume Tapelib TAPE01" returns
nothing.
The tape is no longer listed in the LIBVOLUME inventory.  I have tried to
re-checkin the
tape into the library and have had no luck.  I usually end up having to
discard the data
and start the label and checkin process all over.

Has anyone else experienced the same problem of Tapes being stuck in this
LIMBO
state?  Is there a means for getting the tape recognized as being in use
and back into
the Library in a ready state?
