When a failure occurs on a single fibre channel link, the small form-factor pluggable (SFP) connector might
need to be replaced.
The following items can indicate that a single fibre-channel
link has failed:
- The customer's SAN monitoring tools
- The fibre-channel port status on the front panel of the SAN Volume Controller node
- The fibre-channel status LEDs at the rear of the SAN Volume Controller node
- A SAN Volume Controller cluster,
node, or boot error that indicates a single port has failed
Attempt each of the following actions, in the following
order, until the failure is fixed:
- Ensure that the fibre channel cable is securely connected at each
end.
- Replace the fibre channel cable.
- Replace the SFP connector for
the failing port on the SAN Volume Controller node.
Note: SAN Volume Controller nodes
are supported with both long-wave SFPs and short-wave SFPs. You must
replace an SFP with the same type of SFP that you are replacing. If
the SFP to replace is a long wave SFP, for example, you must provide
a suitable replacement. Removing the wrong SFP connector could result
in loss of data access.
- Have the customer perform the fibre-channel switch service procedures
for a failing fibre channel link. This might involve replacing the SFP connector at
the switch.
- Replace the fibre-channel adapter on the SAN Volume Controller node.
