We are in the process of setting up a new Disaster Recovery scenario
using PPRC DASD and a Hot Stand-by datacenter (z9 CBU processor)
I have a question concerning how others have dealt with using a Coupling
Facility in this scenario. At our DR site we will have one ICF
configured on the same processor our z/OS image will run on .... no
problem so far.
We would like to not maintain multiple CF policies, all Structures at
our primary location will need to be created at the Disaster site. If
the COUPLE Datasets are Mirrored, how can I IPL the DR machine when the
CFs will be different?
Can I code a CF policy that has the DR CF defined as a non-preferred CF
during normal processing and when a DR is called, will the Mirrored z/OS
IPL and fail trying to use the primary CF and failover to the DR CF?
Policy example:
CF NAME(CF01) <==== normal CF
..
..
DUMPSPACE(2000)
CF NAME(CF02) <===== normal CF
..
..
DUMPSPACE(2000)
CF NAME(CFCBU) <====== DR CF
..
..
DUMPSPACE(2000)
STRUCTURE NAME(OPERLOG_STRUCT)
PREFLIST(CF01,CF02,CFCBU)
Would this work if CF01 and CF02 are the "normal" CFs in use and CFCBU
CF would only be used if IPL'd at he DR location?
I rambled a bit, just couldn't figure a way to explain this easily.
