Terry,
The OP mentions 'backup jobs' which suggests to me it might be FDR (or
something else) rather than HSM.
John, Could you be more specific regarding your backup methodology?

If you use HSM to do backups, then the quiesce will be done via HSM
automatically.
Excerpt from z/OS UNIX System Services User's Guide
Data management
In MVS, the storage administrator uses Data Facility System-Managed
Storage Hierarchical Storage Manager (DFSMShsm(tm)) to automatically
back up and archive hierarchical file systems.
Excerpt from z/OS DFSMShsm Implementation and Customization Guide
Identifying DFSMShsm to z/OS UNIX System Services
If you plan to use DFSMShsm to backup HFS or zFS data sets mounted by
z/OS UNIX System Services, you need to define DFSMShsm to z/OS UNIX
System Services as a superuser. This provides the required authorization
to quiesce or unquiesce a file system. DFSMShsm must have a RACF userid
associated with it. That userid must have a default RACF group which has
an OMVS segment with a group id (GID). The userid must also have an OMVS
segment with the following parameters: UID(0) HOME('/'). For additional
information, refer to z/OS UNIX System Services Planning.

We are in a JES MAS, so NJE is not a requirement. We just have a
"requirement" that backup jobs run on SY1. SY2 is supposed to be
strictly for use by the programmers, no production need apply. I hate
our environment anymore. I am a mixture of HFS and zFS at present. In a
basic "bastard"plex.
