Failed SFP
What Caused the Problem?
A Small Form-factor Pluggable (SFP) transceiver
on either the controller enclosure or the drive enclosure has failed, or is inserted incorrectly.
If there is only one SFP failure, the storage subsystem is still operational.
The Recovery Guru Details provides specific information you will need as you
follow the recovery steps.
Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.
Important Notes
- Even though the storage subsystem is still operational, a level of path redundancy has been lost. An
additional SFP failure could result in the failure of the affected enclosures.
- If the Recovery Guru is reporting any other problems, fix those problems first before attempting to fix this problem.
- If the SFP is connected between two drive enclosures, the Bypass indicator lights on both drive enclosures are lit.
- If the SFP is connected between a controller enclosure and a drive enclosure, the Bypass indicator light on the drive enclosure is lit.
- You can replace the SFP while the storage subsystem is in use.
Recovery Steps
1 |
From the Enclosures tab of the Storage Subsystem
Profile, locate the affected SPF. Check the status for the SFPs associated with the enclosure and apply
the status to the table below.
If... |
Then... |
The status is unknown |
A failed ESM may be causing the failure.
Check the Recovery Guru Summary area for a failed ESM entry.
If... |
Then... |
A failed ESM entry is found |
Complete the Recovery Steps for the failed ESM Recovery
Guru problem. |
A failed ESM entry is NOT found |
Go to step 2. |
|
The status is failed |
Go to step 2. |
|
2 |
Check your documentation to be sure you are using a recommended cabling
configuration.
If... |
Then... |
You are using a recommended cabling configuration |
Go to step 3. |
You are NOT using a recommended cabling
configuration |
Remove the SFP that is reporting as failed and insert it into the
port recommended by your documentation.
Go to step 4.

|
3 |
Replace the failed SFP using the location
information provided in the Recovery Guru Details area. |
4 |
Click the Recheck button to rerun the
Recovery Guru. The failure should no longer appear in the Summary area. If
the failure appears again, contact your technical support representative. |
