Hi TSMer's,

At our TSM Server 5.3.4 on AIX 5.3 we use a deviceclass devtype FILE for
database snapshots.

And there is one snapshot:

tsm: TSM1>q volhist t=dbs

       Date/Time: 01/08/2007 15:52:41

         Command:

To delete that snapshot from volhist we entered following:

   tsm: TSM1>del volhist todate=today totime=now type=DBSNAPSHOT
devclass=FILE32G
   ANR6978E DELETE VOLHISTORY: Invalid device class FILE32G.
   ANS8001I Return code 3.


After that we ommited the DEVC:

   tsm: TSM1>del volhist todate=today totime=now type=DBSNAPSHOT

   Do you wish to proceed? (Yes (Y)/No (N)) y
   ANR2467I DELETE VOLHISTORY: 0 sequential volume history entries were
successfully deleted.

Any suggestions how to delete the entries ?

TIA,
Otto
