I have been testing TSM 6.2 on a P570 P5 8 core 32GB box (I'm kinda
lucky right now to have that as a test box).

I am attending TSM 6.1 Advanced Admin and Tuning class right now, and
found out some stuff about Deduplication that I didn't know.  So,  I
went to delete all the filespaces in the system, which were very few,
and it took much longer than I thought it would.  The number on the
process went up very slowly.  This is a file type stgpool, so there is
no shredding going on.

Image my surprise, when I was done, the volumes were all still there!
Query content showed no files, but delete volume creates a process,
and each one runs forever.   I just noticed this one, that failed:

Session established with server TSMCAB1: AIX Server Version 6, Release
2, Level 0.0
  Server date/time: 05/11/10   21:18:01  Last access: 05/11/10   20:59:16
ANS8000I Server command: 'del vol /tsmstg/0000001E.BFS discardd=yes wait=yes'
ANR0984I Process 49 for DELETE VOLUME (DISCARD DATA) started in the FOREGROUND
at 21:18:01.
Error 82 deleting chunk 25026787 from volume /tsmstg/0000001E.BFS
ANR0988I Process 49 for DELETE VOLUME (DISCARD DATA) running in the FOREGROUND
processed 33,581,789,624 bytes with a completion state of FAILURE at 21:26:59.
ANS8001I Return code 4.

ANS8002I Highest return code was 4.

So, server data/time of 20:59, the process didn't start until 21:18,
and didn't finish until 21:26.  I could understand this if it was a
busy system, but this is ALL that it is doing.  Any ideas out there?
I checked before I wrote this, and there is no maintenance or patches
for 6.2 yet.

Thanks for any insight you might have.
