Brian,
You've provided a nice example of defining a primary volume to HSM and
having it dumped on Friday, but you have not addressed the core
flashcopy question for non-SMS volumes.
Is volume C24RES the target of a flashcopy relationship with your true
primary volume? If so, how are you initiating that flashcopy? Do you
perform it on demand via DSS batch job or other automation? Have you
established a permanent (incremental?) relationship of some sort from
the true primary volume to C24RES using Copy Services Manager? What is
your strategy for managing flashcopy?
Thanks,
Ed Jaffe

Yes, you are correct. In the HSM startup you define the volume(s) that you
want and the dumptype(frequency) that you want them to have:
This is for NON-SMS volumes and in this case it's for a z/OS res volume
ADDVOL C24RES /* ADD A VOLUME (PROVIDE SERIAL) */ -
UNIT(3390) /* WITH UNIT TYPE (PROVIDE TYPE) */ -
PRIMARY /* AS A PRIMARY VOLUME THAT IS A */ -
(AUTOBACKUP /* CANDIDATE FOR AUTOBACKUP. */ -
AUTODUMP(FRIDAY) /* DUMPVOLUME AS SPECIFIED */ -
NOAMIG /* CANDIDATE FOR AUTOMIGRATION. */ -
BACKUPDEVICECATEGORY(TAPE) /* BACKED UP TO TAPE. */ -
) /* */ -
THRESHOLD(100 0) /* NO INTERVAL MIGRATION */
And I have FRIDAY defined as:
DEFINE DUMPCLASS(FRIDAY DAY(5) -
RETPD(7) NOAUTOREUSE NORESET -
DATASETRESTORE VTOCCOPIES(4) MINSTACK(4) MAXSTACK(15))
So what ends up happening is that on FRIDAYs, all of the volumes I have defined
this way will be backed up by HSM, I try to keep sets together, meaning volumes
that work together.
Obviously you can change the parms to match what you are expecting to do, but
this way everything is automatically kept under HSM's umbrella, and BACKUP and
DUMP copies of datasets can be used interchangeably.
Otherwise you end up running a batch DF/dss job to do this same thing but
without the benefits of HSM.
If you have questions, feel free to ask.

I've not done this, but, I remember that you can add non-SMS volumes to HSM as
Primary volumes. I've generally thought that this would be so that you can do
the kind of processing you are looking for.

Subject: Re: Flashcopy for Non-SMS volume backup?
Crickets. Fab. 😕
Here's what I'm thinking we should do:
Use DSS to periodically create flashcopy backups of our Non-SMS volumes
using COPY FULL or COPY TRACKS with FASTREPLICATION and
DUMPCONDITIONING. The flashcopy targets would then be dumped using
HSM
BACKVOL with VOLUMES and DUMP (or perhaps be pre-defined to HSM as
PRIMARY volumes for automatic dump processing).
Restoration of a volume dumped this way would be done using HSM
RECOVER
with TOVOLUME, FROMDUMP and TARGETVOLUME potentially followed by
DSF
REFORMAT to CLIP the restored volume to the right volser, if necessary.
What I don't like about this procedure is having to use other utilities
(DSS and possibly DSF) independently of HSM to perform the flashcopy and
perhaps CLIP after restore, but I can't find a way in HSM to make a
flashcopy volume backup occur for other than SMS-Managed volumes. I
have
done a LOT of reading, but I feel like I must have missed something.
I'm curious to learn how other shops handle this.
Thanks...

What is the "best practice" procedure for creating a fast-replication

FRBACKUP makes it easy for SMS-managed volumes...
