We recently purchased a 7720 and need to partition it. We are a monoplex with
TEST and PROD Lpars. The Redbook I was pointed to refers to the DEVSUPxx
Parmlib member and relates it to the Fast Ready Categories on the TS7700
Virtulization Engine. I see no reason to do this as the 7720 has no physical
volumes and we use CA's TLMS as our TMS which manages scratches just fine.
What does make sense is the part about using HCD to define 1 control unit (16
devices) to TEST and the other 15 to PROD and then using Library Port Access
Groups on the TS7700 Virtualization Engine to define the VOLSER ranges.
Currently the Library Port Access Group does not show up on the TS7700
Virtulization Engine. I'm guessing I'm missing a License Code, but I also left
the LIBPORT-ID blank in HCD and need to add it. Any insight woul be appreciated.
1. Do you really need to partition it? Even non-sysplexed systems can
share it, depending on configuration.
2. When you decide to partition it the DEVSUP category statements are
the way to do it. Each system have its own category set.
3. When partitioning you take care about volumes, not the drives. The
drives can be varied ON-OFFline by the operator or software like ATAM.
Last, but not least: you have plenty of (virtual) drives, so you can
assign them to the systems statically, that means assign once and never
change.
4. Don't forget about wise naming convention for the volumes and proper
settings in TLMS. For RMM it would be REJECT ANYUSE statement(s).
5. The above is needed for erroneous volume specific mount requests (job
on TEST want to read from volume belonging to PROD).
6. (pilosophical). No method of sharing provides 100% isolation between
the systems. It is always up to local (TEST) sysadmin to make other
systems (PROD) data unavailable. So the administration on both (each)
systems must trust each other.
