We are building a parallel sysplex.

LPAR1 is still in a monoplex with GRS=NONE. It will be shutdown. Then we
want to bring up LPAR2 with GRS=STAR and join the sysplex.

A couple of questions cropped up.

1. Can LPAR2 be brought up, trying to access the share catalog, RACF
database etc when the other LPAR is not up. What are the gotchas to be
looking for
2. This will be the first time the LPAR is IPL'd with GRS=STAR and
trying to join the sysplex.  Would that extend the time for the IPL and
what would you be looking for during the IPL?  Would it take 2-3 hours to
be confident it was working - e.g. CDS are okay, an all other parallel
sysplex configurations?
3. What happens when LPAR1 comes up and then joins the parallel sysplex?


Thanks
