What Caused the Problem?
Two or more drive channels are connected to the same Fibre Channel loop. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Important Notes
When two or more drive channels are connected to the same Fibre Channel loop, the storage subsystem could behave unpredictably.
Caution
It is highly recommended that you suspend all I/O before performing this procedure. Removing cables from a working storage subsystem can cause data loss. If you are not familiar with your cabling configuration, contact your technical support representative.
Recovery Steps
1 |
Use the information provided in the Details area to determine which drive channels are miswired. Trace the cables from the controller enclosure's miswired channel connections to the drive enclosures. Follow the cable paths until you find a connection where two different channels are connected to the same ESM canister. The following diagrams show common miswire configurations:

2 |
Reconnect the cables so there is only one drive channel on a Fibre Channel loop. Use the Interface Cable Routing Examples in the Controller Enclosure and Drive Enclosure Installation Guide as a reference. |
3 |
Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed. |
