1) Assuming the task is not consuming CPU or IO, is this a problem?
Perhaps HSM has nothing to do.

2) What does F DFHSM,Q ACTIVE show? Likewise, F DFHSM, Q REQ?

3) Check for a CDS Backup running during some other long running (e.g.
recycle) task.
Activities will "stack up" until the CDS backup completes.
Issue d grs,c to confirm, although it should show up on the Q active
command.

HTH,

Subject: DFHSM hang condition on z/OS 1.9.

Has anyone noticed an occasional 'hung condition' on DFHSM lately? Where
the task is just stuck and doing nothing?

This has happened about 2-3 times over the past few months and at
different times/conditions.
