killing running mmbackup processes on all participating nsd server

In some circumstances (maintenance window / problem investigation) it is important for us to kill all mmbackup sessions on a scale cluster.

We, as the storage and backup admingroup in our company struggeling currently in missing a feature that mmbackup don't has.

The feature we miss is to feed the mmbackup environment with a parameter to kill all running mmbackup processes on all participating nsd server.

Invoking /usr/lpp/mmfs/bin/mmbackup $fsName -N nsdserver starts the whole process for a specific file system.

The nsdserver parameter starts subprocessing tasks on all participating nsd server.

If we interrupt (ctrl +c) the mmbackup command (started in the foreground), all running subtasks will be terminated and exit0 follows.

If the mmbackup currently is running in the background it is very difficult to identify all subsequent processes to kill.

For this it would be a great help to invoke the mmbackup environment with a kill parameter (e.g. -k $fsName)

Thanks in advance.
Best wishes
Roland
