That's what my CE thought for a while too.  Removing the flourescent from
above the 3494 gave temporary relief, but the real problem was that the
door was ajar just enough to make the upper portion of the row opposite the
hinge occasionally unavailable.  Once he levelled off the door, no more
problems.

As strange as it sounds we have had problems with our library with the
ambient light.  Cover the window above that section and see if it fixes the
problem.

Hope that helps.

Subject: Very Strange Problem related to IBM 3494 library


     Hi ,

     I am facing a very starnge problem.

     My Environment is:

     IBM Backup System: NSM 3466 C-30
     RS 6000 , OS version AIX :- 4.3.2
     TSM : 3.7.4.0

     Hardware :

     IBM 3494 Library
     1 Gripper
     3 frames in total
        L12
        D12
        S10

     3590 E1A Magstar Tape Drive ( 3 Nos.)

     Problem Description : ( Wondering how to describe this...)

     The library is not able to checout volumes from a particular section
     of slots ( from cell no. 5 E 1 to 5 E 20 , in S10 frame).

     5 - Rack No.

     E - Column No.

     1 and 20, - Cells ( 1 is at the top...)

     Though , it is able to checkout tapes in the same column (i.e 5 E)
     from cell no. 21 onwards.

     The surprise doesn't end here.

     The problem is only with the checking out the volumes.The Automatic
     robot is able to mount/dismount these particular tape volumes to/from
     the drives.

     When I try to checkout the volumes from the above mentioned cells
     following are the observations:

     1. ) The library changes it's state from AUTO to PAUSE.

     2.) Operator intervention LED starts to blink.

     3.) I get following message on the library manager console:

     A cartridge could not be released from Gripper 1 , Accessor A
     The system has failed.
     A service call is required.

     When I see the service log, the error code is 2BC2.

     After that I clear the message and try to turn the library to AUTO.
     The library puts the volume back to it original cell and turn to AUTO
     mode and start functioning in a normal behaviour.

     But the volume is not checked out.

     On the ADSM side I get following error message:

     ANR8310E : An I/O error occurred while accessing the library.

     Action taken :

     1). Power Reclycled the library.
     2.) Re-inventoried the library.
     3.) Teaching done once again.
     4.) ADSM Server restarted.

     Any inputs shall be greatly appreciated.

     Thanks and Regards

     Mahesh
