Lionel,
It's been a long time since I was spaceman...
Do recall that I used to direct HSMBACKUPS to the correct Library (I did my
fair share of ATL migrations lol) via the ACS constructs...based on name a

I can spell HSM and am learning more about it - I have these questions that
I haven't found the answer to in the pubs (yet).

I can spell HSM and am learning more about it - I have these questions that
I haven't found the answer to in the pubs (yet).
1. How can I change the default unit for HBACKDS datasets from tape to
disk?
2. I have 2 virtual tape libraries - how do I force HSM to only use the
tapes in
If it happens again, open a pmr. ISPF uses device type to determine if
MIGRAT'x' corresponds to ML'1', ML'2' or ML'C'. Since you are seeing a 'C',
but have never targeted 'C'loud object storage, there could be a defect in
which the device type is not being set appropriately. Thx.
One last thought. It would have been interesting to see what the device type
was in the catalog entries. This is what is used by ISPF 3.4 to determine
whether a migrated data set is MIGRAT1, MIGRAT2 or MIGRATC.

Oops, never mind. Missed the part that you had not tried out the cloud support.

Hi,
Is there a chance that someone has tried out the Cloud support in HSM? MIGRATC
would normally indicate that a data set has been migrated to a cloud platform
of some kind.

DFSMShsm questions
Hi Listers,
Low priority, curiosity, silly question for you. How does one get a migrate
status of MIGRATC? I was doing some cleanup for a developer on Friday and
stumbled across 2 catalog entries for datasets that were in MIGRATC status. We
don't do anything with the cloud
