No, not exactly.
First, I meant "regular" sysplex. In that case it is possible and
recommended to have SMSplex=sysplex.
However it is also possible to have multiple SMSplexes within a sysplex,
and within GDPS.
And I mean SMSplex can be cross-plex - yes, it is possible. Multiple
non-sysplexed systems can share SMS.
Correct me if I'm wrong.

SMSPLEX=SYSPLEX: no, you can't.
GDPS K-systems cannot share Dasd with GDPS P-systems, so they must have
separate SMS plexes.
If you mean: an SMSplex cannot cross Sysplexes: that is true.

Subject: Re: Creating new SMS environment in a monoplex
To complement: there is strict requirement to have SMSplex = Sysplex.
SMS, as many other system components does support multihost configurations.
Multihost could mean several monoplex systems and shared CDS datasets on
shared volume.
Multihost could also mean SMSplex which covers some sysplex and few
monoplexes together.
SMSplex could also cover part of sysplex, so different sysplex member
may have different SMS settings.
As usually IBM recommend to keep SMSplex = sysplex.
Note: the above apply to DFSMSrmm, OAM (and tape libraries), etc.
However each system component may have it's own specifics/restrictions.
AFAIK, in the very old days JES2 MAS could go beyond sysplex. Now it is
impossible - JES MAS is available only within sysplex boundaries.
However it is possible to have more than one MAS within sysplex.
Sometimes sysplex=*plex give some advantages, especially sysplex
communication and CF structures.
