704 Fewer Fibre Channel ports operational.

Explanation
A Fibre Channel
port that was previously operational is no longer operational. The
physical link is down.
This node error does not, in itself, stop the node
becoming active in the system. However, the Fibre Channel network
might be being used to communicate between the nodes in a clustered
system. Therefore, it is possible that this node error indicates the
reason why the critical node error 550 A cluster cannot
be formed because of a lack of cluster resources is
reported on the node. 
Data:
Three numeric values are listed:The ID of the first unexpected inactive port. This ID is a decimal
number.
The ports that are expected to be active, which is a hexadecimal
number. Each bit position represents a port, with the least significant
bit representing port 1. The bit is 1 if the port is expected to be
active. 
The ports that are actually active, which is a hexadecimal number.
Each bit position represents a port, with the least significant bit
representing port 1. The bit is 1 if the port is active. 

User response
If possible, use the management GUI to
run the recommended actions for the associated service error code.
Possibilities:If the port has been intentionally disconnected, use the management GUI recommended
action for the service error code and acknowledge the intended change. 
Check that the Fibre Channel
cable is connected at both ends and is not damaged. If necessary,
replace the cable. 
Check the switch port or other
device that the cable is connected to is powered and enabled in a
compatible mode. Rectify any issue. The device service interface might
indicate the issue. 
Use the remove and replace procedures to replace
the SFP transceiver in
the 2145 node and the SFP transceiver in
the connected switch or device. 
Use the remove and replace procedures
to replace the adapter. 

Possible Cause-FRUs or other cause:
Fibre Channel cable
SFP transceiver
Fibre Channel adapter
