Re: Backup Stgpool Process hangs, not cancelable

Have you looked at the value of "Current Physical File" - it is 55,767,181,387.
TSM Server does not increment the "Bytes Backed Up" value until the
transaction finishes and it may take a lot of time (calculate yourself how
much should take 55 GB with your tape technology). Whatever number of
times you query, the result will be the same - the file is not yet
successfully backed up. And if there is some unsatisfied mount request
pending, it may even finish with failure.
If you issue the "cancel process" command, the cancel is pending but the
process ends again after transaction completion.

On the end if you had not enough patience to wait for the successful
completion, the only method for force-cancel of the process is to use
command "halt"! Sorry, no better answer.

Hi TSM'ers,

my daily backup storagepool works fine since yesterday. The process
started with a central script. All storage pools are copied fine during a
few minutes. But the last of them, TAPE_BACKUP_001, probably the biggest
will not finish for more then 20 hours. I queried the process severalt
times, but there is no change in the current physical File bytes. So I
tried to canel the process. The command was accepted, but the process
doesn't stop.

 Process Process Description  Status

     455 Backup Storage Pool  Primary Pool TAPE_BACKUP_001, Copy Pool

Current input volume:
                               000082.
Current output volume: 000026.

-> I tried it again:
ANR0941I CANCEL PROCESS: Cancel for process 455 is already pending.

-> I put the status of the volume to unavailable - command refused:

ANR2405E UPDATE VOLUME: Volume 000082 is currently in use by clients
and/or data management operations.
ANR2212I UPDATE VOLUME: No volumes updated.

-> I looked for locks:
show locks:

  Holder: Tsn=0:11809139, Mode=sLock

My Question: Has anyone a idea, how I can stop this process without shut
down the server?

Thank you for Help
