Larry - appreciate the detail you provided.
However, I have had problems on new release, when there was an ipl before
the cume.
This was several releases ago, and involved hardware recognizing some
components.
IBM had the fix in the cume (they caught it early). Since then, I have
always done
Release
Cume (follow instructions), including ipl (and there is a warning to follow
other instructions on an lpar system)
Make sure inzsys is done
load Groups & Hiper
apply delayed *yes Groups & Hiper & ipl
same for just Cume & Groups/Hiper

not been burned since that one (early server model).
(just a general warning to others - never run in production a machine
without a Cume loaded - maybe Al Barsa or others can clarify, but it is my
understanding that the base release is frozen prior to release date & the
1st cume has fixes found in the pre-release period).
