Description
We no longer need CPF on this system. How do I remove it without affecting other processing?
Solution
CPF can be removed from the system without an IPL. These are the steps:
- Issue a SHOW CPF to determine the current environment, i.e.; the names of the journal files to be deleted and the identity of other nodes whose CPF records may have to be changed.
- Set NOCPF in the GSO OPTS record for the appropriate sysid.
- REFRESH the OPTS and CPF records.
- Issue SHOW CPF to verify it is stopped.
- Follow up with a SHOW CPF on the other nodes in the network (see #1).
- Delete the NODEDEF record defining this node from the CPF records at the other nodes.
These are the ACF2 and operator commands to accomplish these steps:
- acf
show cpf
- set c(gso) sysid(xxxx) for local sysid
cha opts nocpf
- set c(cpf) sysid(xxxx)
del options
del like(nodedef-)
- f acf2,refresh(opts)
f acf2,refresh(all),type(cpf)
- set c(cpf) sysid(yyyy) for local sysid
del nodedef.zzzzzzzz where zzzzzzzz is the name of the node being deleted
f acf2,refresh(nodedef),type(cpf)
If the CPF OPTIONS record on the remote systems includes references to the deleted node, issue the following commands as appropriate:
cha options dftcmd(zzzzzzzz) del
cha options dftpsw(zzzzzzzz) del
f acf2,refresh(options),type(cpf)
