Hmm, I tried running the "cleanup backupgroups" command and got the
result:
ANR0106E imutil.c(8262): Unexpected error 0 fetching row in table
"Object.Ids"

<Sigh> Seems to be a known problem. (and I'm running 4.2.2.12)

Error Description:
The cleanup backupgroups utility was created to cleanup orphaned entries
within a TSM server database table. While running this utility function to
perform the cleanup some addtion problems with the datbase entries were
encountered. When this occured ANR0106E imutil.c(3804): Unexpected error 0
fetching row in table "Object.Ids" was received. In addtion due to the long

running nature of this cleanup activity an enhancment to this code was
needed to make it a server process that could be cancelled and restarted if
needed. If restarted it should begin processing where it left off.

Local Fix:
Apply patch 4.2.2.12 or higher, available through
Tivoli Web Page to resolve this problem, or fixing
PTF when available.


Problem Summary:
****************************************************************

*                      It runs as a foreground process         *
*                      without displaying any status and can   *
*                      not be stopped and restarted.           *
