I use full volume copy for the sysres vols and dfdss logical copy for
the z/FS files.
Our sysres sets are 3 -3390-3 for non-VSAM and 2 3390-3 for VSAM( ZFS).
We use the target volser as part of the DSN to ensure unique names per
version across multiple images.
Sample DFDSS control cards (one volume omitted for brevity).

Our upcoming migration from HFS to zFS for the root file systems is
causing a
new problem for us.
The previous maintenance method was to keep the HFS root file system on
the sysres with all other non-VSAM SMPE-target files. All datasets were
implicitly cataloged at IPL time. By replacing the SYSRES volume a total
replacement or back-off of maintenance was just an IPL away. We
currently
are running from a single mod 27 sysres. The rest of the HFS/ZFS file
systems
will be mounted from other non-SMPE impacted volumes.
The zFS file systems on the other hand is subject to the special volume
ownership and naming requirements of VSAM. We can no-longer use a simple
full volume copies to transfer the test SYSRES to production. Further it
looks
like a second dump will need to be done of the test zFS root files and
then a
restore with the RENAMEU option run made under the production master
catalog. We may even have to put the zFS files on separate sysres
volumes
which are "owned" by the production system catalog structure.
