Skip has talked about this in the past and in SHARE sessions.
What we have done for years is use a different "newly formatted" sysplex
couple and CFRM couple data sets that we IPL with during DR. This has
also been discussed.

That's what we do at DR also. I was wondering if the first IPL with the
incorrect CFRM policy 'corrupted' the sysplex couple dataset in such a
way that it didn't re-read the CFRM couple dataset for the policy which
was rewritten with the correct CPU serial number.

Mark, I don't know but we used to run into the same problem at DR until
we started defining our CFRM policy with 4 CFs.
CF1 and CF2 are the ones at home. CF3 and CF4 are the ones at DR.
I define the policies with a preflist of (CF1,CF2,CF3,CF4).
Now when we're at home or DR IPL proceeds without a hitch.
I think I got the idea for doing this from a post on this list a few
years ago.

Subject: SYSPLEX/CFRM Couple dataset(s) relationship
At our last DR exercise we had an incorrect CPU serial number in our
CFRM policy which resulted in a failure in our IPL. We fixed the CFRM
policy and re-wrote it replacing the incorrect policy (same policy
name).
When we re-ipled, the system was still looking for the CF lpar with the
incorrect CPU serial number even though the CFRM policy with the old
serial number wasn't in the CFRM dataset. We couldn't get the system to
IPL until I deleted and redefined the SYSPLEX couple dataset.
Does the sysplex couple dataset retain information about the CFRM policy
in use other than the name of the last used CFRM policy?
