"a fully configured parallel sysplex" - in the sense you meant it - is
something I see less often than I'd like. :-(
As a Performance guy, often the conversations I have with customers - based

If you have a fully configured parallel sysplex, disruption to clients
should be minimal. On balance, less disruption than a system crash caused
by downlevel maintenance.

One of the things that you "lose" when only IPLing once or twice per year is
the ability to install maintenance on a more frequent basis, at least anything

very foolish.

I was impressed with maintenance on the Tandem system (now HPE non-stop) where

I would use 24X365. Of course that does not take into account the Leap Year
day.
24X7X52 is more correct.

hi,
150+ LPARS - Maintenance related IPLs probably once a year (sometimes out to 18
months between IPLs on some LPARs).
IPLs are a scarce event.
PORs only occur when the actual boxes get upgraded to latest zSeries box.
