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

  1. If possible, use the management GUI to run the suggested actions for the associated service error code.
  2. 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.
    • Use the remove and replace procedures to replace the adapter. If this procedure does not fix the problem, then replace the node canister (system board in 2145-DH8 and 2145-SV1).

Possible Cause-FRUs or other cause:

  • Fibre Channel cable
  • SFP transceiver
  • Fibre Channel adapter
  • Node canister (system board on 2145-DH8 or 2145-SV1)
