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 or node canister from becoming active in the
system. However, the Fibre Channel network might be being used to communicate between the nodes or
node canisters 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 or node canister. 
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 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 suggested actions for the associated service error code.

     Possibilities:
       If the port was intentionally disconnected, use the management GUI suggested 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 system and the SFP transceiver in the connected switch or device. 

       On Storwize® V5000, Storwize V5000E, FlashSystem 5000,  Storwize V5100, FlashSystem 5100,  and  SAN Volume Controller, use the remove and replace
procedures to replace the adapter. 

       On Storwize V7000,   FlashSystem 7200, FlashSystem 9100,  and FlashSystem 9200, because the adapter is on the
system board, replace the node canister by using the remove and replace procedures.
