Fibre Channel and 10 Gbps Ethernet link failures

You might need to replace the small form-factor pluggable (SFP) transceiver when a failure occurs on a single Fibre Channel or 10 Gbps Ethernet link.

Before you begin

The following items can indicate that a single Fibre Channel or 10 Gbps Ethernet link failed:
  • An error that indicates that a single port failed (703, 723).

About this task

Use only supported 10 Gbps .SFP transceivers Using any other SFP transceivers can lead to unexpected system behavior.

Procedure

Attempt each of these actions, in the following order, until the failure is fixed.

  1. Ensure that the Fibre Channel or 10G Ethernet cable is securely connected at each end.
  2. Replace the Fibre Channel or 10G Ethernet cable.
  3. Replace the SFP transceiver for the failing port on the node.
    Note: If the system is supported by both longwave SFP transceivers and shortwave SFP transceivers. You must replace an SFP transceiver with the same type of SFP transceiver. If the SFP transceiver to replace is a longwave SFP transceiver, for example, you must provide a suitable replacement. Removing the wrong SFP transceiver might result in loss of data access.
  4. Perform the Fibre Channel switch service procedures for a failing Fibre Channel link. This procedure might involve replacing the SFP transceiver at the switch.Perform the Fibre Channel switch or FCF service procedures for a failing Fibre Channel or 10 Gbps Ethernet with Fibre Channel over Ethernet personality enabled link. This procedure might involve replacing the SFP transceiver at the switch.
  5. Replace the Fibre Channel adapter on the node.
