Fibre Channel and 10G 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 10G Ethernet link.

Before you begin

The following items can indicate that a single Fibre Channel or 10G Ethernet link failed:

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

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

Ensure that the Fibre Channel or 10G Ethernet cable is securely connected at each end.
Replace the Fibre Channel or 10G Ethernet cable.
Replace the SFP transceiver for the failing port on the node.
Note: IBM Spectrum Virtualize™ nodes are 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.
Replace the Fibre Channel adapter on the node.
