Strange problem. AIX 4.3.3, TSM 5.1.5.4.

Im trying to run reclamation on our copy storage pool. There is only one
tape left, and reclamation continually starts and ends successfully for it
without moving any data and no time passing:

11/18/03   06:53:26      ANR0984I Process 2215 for SPACE RECLAMATION started
in the BACKGROUND at 06:53:26.

11/18/03   06:53:26      ANR1040I Space reclamation started for volume
J00840, storage pool COPY_POOL_01 (process number 2215).

11/18/03   06:53:26      ANR0985I Process 2215 for SPACE RECLAMATION running
in the BACKGROUND completed with completion state SUCCESS at  06:53:26.

The volume in question reports as being "100% reclaimable", "0% utilized"
and status of "full" from a q vol:

ANR2232W This command will move all of the data stored on volume J00840 to
other volumes within the same storage pool; the data will be
inaccessible to users until the operation completes.

Do you wish to proceed? (Yes (Y)/No (N)) y
ANR2209W Volume J00840 contains no data.
ANS8001I Return code 11.

>q content j00840
