Hi,
1. Environment:
   ============
   Server: IBM H70, AIX 4.3.3, TSM 4.2.1.8

2. Problem:
   ========
   Since a few days I see the following in the activity-log:(e.g.)

17.07.2002 15:01:24      ANR9999D afmigr.c(2918): ThreadId<59> Error
deleting
                          volume 000104, 0 bytes moved by reclamation.


   The tape in question "000104" seems to be empty accordingly to:

tsm: DS3>q vol 000104 f=d

                   Volume Name: 000104

3. Trying to solve
   ===============

   1. Via DEL VOL
      ===========

17.07.2002 14:57:45      ANR2017I Administrator C0034003 issued command:
DELETE
                          VOLUME 000104
17.07.2002 14:57:51      ANR2017I Administrator C0034003 issued command:
DELETE
                          VOLUME 000104
17.07.2002 14:57:51      ANR2406E DELETE VOLUME: Volume 000104 still
contains data.
17.07.2002 14:57:51      ANR2017I Administrator C0034003 issued command:
ROLLBACK


   2. Via MOVE DATA
      =============

17.07.2002 14:59:27      ANR2017I Administrator C0034003 issued command:
MOVE DATA
                          000104 stgp=copypool_nc

17.07.2002 14:59:27      ANR2232W This command will move all of the data
stored on
                          volume 000104 to other volumes within the same
storage
                          pool; the data will be inaccessible to users
until the
                          operation completes.
17.07.2002 14:59:29      ANR2017I Administrator C0034003 issued command:
MOVE DATA
                          000104 stgp=copypool_nc
17.07.2002 14:59:29      ANR2209W Volume 000104 contains no data.
17.07.2002 14:59:29      ANR2017I Administrator C0034003 issued command:
ROLLBACK


4. Big Questions:
   =============

   1. Which is right? DEL VOL or MOVE DATA
   2. I haven't tried yet
        DEL VOL 000104 DISCARD=YES
      Should I ?
   3. Anything else to consider ?
