CF - CFRM Question.

We are z/OS V2.2. While I was updating the IODF It was decided to change the Couple Facility Partition Identifier (CFA) from 8 to 9. Nothing else about that partition was changed.

Also another CF Partition was created as CFB with Partition Identifier 9. At this point nothing is attached to this partition.

I was informed since the partition ID was changed that the CFRM needed to be updated.

So I added the additional CF NAME and updated the PARTITION #.
CF NAME(CFA)
TYPE(00XXXX)
MFG(IBM)
PLANT(02)
SEQUENCE(000000094037)
PARTITION(9)
CPCID(00)
DUMPSPACE(367002)

CF NAME(CFB)
TYPE(00XXXX)
MFG(IBM)
PLANT(02)
SEQUENCE(000000094037)
PARTITION(8)
CPCID(00)
DUMPSPACE(367002)

Also updated all STRUCTURE's with PREFLIST with CFA & CFB.

STRUCTURE NAME(XXXXXX_XXXX_X)
SIZE(172128)
INITSIZE(114752)
FULLTHRESHOLD(90)
ALLOWAUTOALT(NO)
REBUILDPERCENT(1)
DUPLEX(DISABLED)
PREFLIST(CFA,CFB)

Then executed the utility and received a Cond code 0.

During the IPL the following message was received:

IXC518I SYSTEM XXXX not using CF
........
Reason: Not in the CFRM active policy
Reason Flag: 13300002.

NOT IN THE CFRM ACTIVE POLICY. REASON FLAG: reason.
The CFRM active policy does not have this coupling facility defined. The coupling facility is connected to the system but will not be used since not in CFRM active policy.

After that re-occurring error messages .

At this point I decide to change the partition number back to 8 in the HMC and re-activated the CF.
I also put back in place the old CFRM. RE-IPL and was able to successfully bring the system back up.

What would be the correct way to update this ? What I have been able to find is to create a new CFRM and then perform a SETXCF START,POLICY,TYPE=CFRM,POLNAME=CFRMXXXX.
Do I update the current CFRM?
Can I use the same POLNAME ?
How do I switch to the updated CFRM ?

Any help would be appreciated.

We were also wondering how the system was able to use the partition # defined in the CFRM as partition 8 but the IODF has it defined as partition 9.

Thank You

Did you deactivate and activate the new CF LPARs?

The CFRM CDS has 8 slots to store policies by 'PGM=IXCMIAPU' and different names from 'DEFINE POLICY NAME(xxxxxxxx)'.
With SETXCF START,POL,TYPE=CFRM,POLNAME=xxxxxx you make one of the policies the active policy. This policy is copied to the slot of the 'active policy', so you could overwrite the policy with its original name again, without changing the 'active' policy. Although I recommend using new names for new policies, so you can activate the new policy and as easily, you can activate the old policy again in case of problems.
