Check the maxscratch parameter on the tech_tape_pool storage pool with q stg  
tech_tape_pool f=d 
You can either increase this number with upd stg to allow more scratch tapes to 
be used by this pool, or use define volume to explicitly add volumes to the 
pool.

Once you have done that your reclaim should work.

Hi All,

I have a big problem here. Help requested.

I have a 3583 LTO library with 2 drives. TSM Server v4.2 on AIX.

I have been running Scheduled backups without any problems so far.

Yesterday the server started reclamation process for one of the Storage
pools as shown below.


784 Space Reclamation    Volume 053ABS (storage pool TECH_TAPE_POOL),
                               Moved Files: 0, Moved Bytes: 0, Unreadable

                               Files: 0, Unreadable Bytes: 0. Current
Physical
                               File (bytes): 10,487,404
Waiting for mount of
                               input volume 053ABS (68221 seconds).

Some of the activity log entries are :

053ABS -
                       insufficient space in storage pool.

The volume status shows no errors with the volume.


 Volume Name             053ABS

 Storage Pool Name       TECH_TAPE_POOL

 Device Class Name       ULTRIUM

 Estimated Capacity (MB) 137997.9

 Pct Util                0.0

 Volume Status           FULL

 Access                  READWRITE

 Pct. Reclaimable Space  99.9

 Scratch Volume?         Yes

 In Error State?         No

 Number of Writable      1
 Sides

 Number of Times Mounted 12827

 Write Pass Number       1




Even though both the tape Drives are free, and a scratch volume is made
available, all the migration processes are Held up.

Could somebody help me understand & suggest a solution to the problem here.

Thanks in advance

murthy
