Great discussion here. For those who are interested, here is a link to
charts/recordings for a DFSMShsm education series. One of the sessions is
specifically on the DFSMShsm control data sets that discusses RLS, CA Reclaim,
Reorgs, etc. Feel free to contact me with any questions.
I also try to keep it simple and these are the steps I perform for re-sizing
the HSM cluster. Beside the shutdown and start up commands, all else is within
a single batch job.
1) Shut down HSM.
2) Run a listcat of the HSM cluster.
3) Back up the HSM cluster to tape.
4) Export the file via

I would suggest using extended addressability VSAM to avoid the 4GB limit as
well as considering multi-cluster CDSs (for MCDS and BCDS, don't think it is
supported for the OCDS). I'd also recommend using RLS as I've
suggest devoting an

That's what I've been doing.
I use sort to copy, and do the rename after the copy, but it general it's the
same process.

Hello Peter,
Your approch to the matter applies to resizing any VSAM KSDS data set.
Just make it simple, do not over think.
Your method is probably the best even though it has been used for ages.
I wish there was some new method to do the same as with this method you must
shut down HSM.

Hello
Apologize for basic question
Whats your approach on resizing HSM MCDS ?
is it just defining MCDS, Rename, repro old to new and start HSM task ?
