Mauri/all,
I missed this earlier. We are a basic sysplex only, no CF running
here. Just wanted you to know this...

Just one more addition ...
Maintenance was applied to CFs<snip>
The only problem my client ran into with zEnterprise was the new CF level
foot print. 2 different sandbox plexes each had 2 CFs (one internal and
one external) with 512M of storage, which was always enough in the past.
The CF level 16 CFCC took about 90M and CF level 17 took over 400M.
I couldn't find this documented anywhere nor was it mentioned in any
of the reviews we had with IBM prior to the upgrades from z10s. We
just bumped up the storage to 750G in each CF LPAR and that was enough
because the structures used took less than 150G.
When we finally got confirmation that this was expected, this was the
detail behind the growth:
"the growth of the image is do to many enhancements in function and recovery in
the CFCC 17 code. CFCC 17 on z196 has added some function and added enhanced recovery of
the CF code. The number of supported structures was increased from 1023 to 2047
structures, the number of logical connection to a structure was increased, and the
recovery was enhanced to improve nondisruptive MCL activation to maintain code levels and
the ability to take nondisruptive CF dumps. CFCC recovery code has been added to take
nondisruptive dumps of the CF and signal all connected images with a CRW machine check to
invoke sysplex wide SVC and nondisruptive CF dumps for some CF recovery events to gather
problem data."
