Two ESM canisters in the same drive enclosure 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.
When two ESM canisters in the same drive enclosure are connected to the same Fibre Channel loop, a level of redundancy is lost and the I/O performance for this drive enclosure will be reduced.
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.
1 | Use the information provided in the Recovery Guru Details area to determine which drive enclosure's ESM canisters are connected to the same Fibre Channel loop. The following diagrams show common miswire configurations:![]() ![]() |
2 | Reconnect the cables so that the ESM canisters are on different Fibre Channel loops. 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. |
