My instructions to operations (which has always worked and I have tested
many times) is to wait for this message prior to starting to IPL the next
LPAR when IPLing multiple LPARs in the sysplex"
ISG004I GRS COMPLEX JOINED BY SYSTEM sysname
This is right after all the couple data set processing.

Thanks Gary that is excellent information. We are actually a test lab andwe are trying to IPL 15 LPARs at one shot. At this point we have not be able
to get them all up in a sysplex environment. I am trying to figure the best
way to tune the sysplex to make that happen.

Chris,
If you're actually getting these, it's an improvement over what used to
happen when you IPL'd systems too closely together chronologically.
They used to either wait state, or go out to "la la land" and never
report back, load an OS, or wait state (green on HMC, "operating", but
no OS ever shows up). Images/LPARs that are IPLd too close together
appear to be fighting over access to the CFs to check in to the PLEX,
and from what I've seen the CFs only seem to be able to check in one
system at a time in a very serial manner.
Wait until the LPAR joining the plex is responding to a routed D A,L
command and has at least one task started before performing the
load/activate on the next LPAR. (alternately, wait 2-3 minutes between
activations, that seems to work as well)
Hope this helps,
Gary Diehl
