The responses "NOT ALL PATHS BROUGHT ONLINE"
after attempting to configure the CHPID online and
"FICON INCOMPLETE" in the display example indicate
that the channel did not come online. You can
determine this because the IEE error types are shown

attempt to do a basic FLOGI (no light displayed on the
port view (LED) and no Fibre Channel frames were
received).
The Control Unit Port cannot access the switch. Domain or port ID has changed on CHPID link.
A two-byte CHPID link is defined using a domain and

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.

Use the haFailover command on the Backbone. This
the only known fix as there is no known firmware
solution.
