Troubleshooting FICON

+ ONLINE @ PATH NOT VALIDATED - OFFLINE . DOES NOT EXIST
* PHYSICALLY ONLINE $ PATH NOT OPERATIONAL
The responses "NOT ALL PATHS BROUGHT ONLINE" after attempting to configure the CHPID online
and "FICON INCOMPLETE" after the display command indicate that the channel did not come
online. This is determined because the IEE error types are shown and combined with validating that
there was no attempt to do a basic FLOGI (no light displayed on the port view (LED) and no Fibre
Channel frames were received).
Symptom The Control Unit Port cannot access the switch.
Probable cause and recommended action
A 2-byte CHPID (channel path identifier) link is defined using a domain and port ID that must
remain consistent. Any change in the physical link, such as a change in a domain or port ID, will
prevent storage control unit access.
Use the configure command to verify and set the insistent domain ID (IDID) parameter.
FICON:admin> configure
For more information and examples of using this command to set the IDID parameter, refer to the
Configure command in the Fabric OS Command Reference Manual.
Symptom Unable to "vary online" FICON CUP port on the switch.
Probable cause and recommended action
Use the haFailover command on an enterprise class chassis. This the only known fix as there is no
known firmware solution.
