[slurm-users] scontrol issue: Update of this parameter is not supported: StepId=

[Cook, Malcolm]

I am trying to change the JobName of a running task, like this

        scontrol update StepId=24236.0 JobName='my new name'

and getting errors in the log file like this:

        Update of this parameter is not supported: StepId=24236.0

I get the same error when I try:

        scontrol update step StepId=24239.0 JobName='my new name'

The following works to change the whole job's JobName

        scontrol update  JobID=24239 JobName='my new name'

Should updating the JobName for steps not be expected to work?

Perhaps I have the syntax incorrect?
