I maintain a system where we are sharing a SYSRES from 7 lPARs. It works
well. We invested in the setup time. Rules, too, like only one system
maintains the contents of SYSRES (modules, config files, etc.). The
config file use the imbed statement. Each system has private spool,
warm, ckpt, page and directory. Maintenance is clean, and we know each
system is running the same exact CP load module.
As fas as NSSes go, we have a procedure where we copied a "good spool"
containing almost exclusively NSS files, re-labeled to an appropriate
volume, and off we went.
For what it's worth we also share a racf db on 6 lpars.
This is not a CSE environment.
I find it worthwhile otherwise I wouldn't have spend time in the
woodshed tooling it up. Or maybe I would have anway.
By the way SYSRES can be marked read-only! Heck it is just used to load
code, config, sapl, etc.

I'd have to disagree with your final assessment. MVS systems don't have
spool, checkpoint, paging on the sysres either, and sharing the sysres,
or being able to dump/restore it intact, tremendously reduces the amount
of effort to roll updated sysres volumes across many systems. Why
can't/shouldn't the same savings be possible on VM?
So you'd like to share 190, 193 as well as your program product disks
accross systems? That's what CSE is good in. Works much better than
trying to keep directory definitions similar. You could copy segments
using the stuff we inherited form IPF, and since the 190 and GCS disk
are shared, saving the NSS is not that hard.
