Acknowledged, but I was more concerned that newly allocated file systems
might misbehave if we changed an existing DC. I was able to get around
the problem I was having due to the efforts of the many bright people in
this mailing list.

The data class is an initial source of data set attributes. The vast
majority of data set attributes are stored in the VTOC/VVDS and catalog
entries when it is allocated, therefore changing the data class after the
data set has been allocated does not change its attributes.

Subject: Re: Calls to SMS Data Class ACS Routine
Understood. Can anyone give me some ideas on how to copy ZFS file
systems from non-EAV volumes to EAV volumes when the Data Class that
they're defined with doesn't have EATTR(OPT) assigned?
I'm a little leery having our Storage Admin change the existing Data
Class, I'd rather have the datasets use a new one.

The newly allocated SYSZFS dataset gets assigned the correct storage

from the source dataset.
I know the SMS routines are working since a regular allocation of a
SYSZFS
dataset in JCL assigns all the expected attributes.
Thanks. I had to RTFM and check my old DFDSS jobs, but I think this part
from DFSMSdfp Storage Administration applies:
"For the COPY command (&ACSENVIR='ALLOC') and the RESTORE command
(&ACSENVIR='RECOVER'), the storage class ACS routine is executed first. If
the storage class is not null, the management class ACS routine and then
the
storage group ACS routine are executed."
Seemed nothing is said about data class... UnlessI miss something...
Look at O'Brien, David W. reply too.
