Purpose
Resolution
Please validate that each troubleshooting step below is true for your environment. Each step will provide instructions or a link to a document, in order to eliminate possible causes and take corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.
To troubleshoot connectivity issues to a fibre channel array:
-
Verify that ESX or ESXi cannot see any targets in a shared storage environment. For more information, see Obtaining LUN pathing information for ESX hosts (1003973).
-
Verify that a rescan does not restore visibility to all the targets. For more information, see Performing a rescan of the storage (1003988).
-
Verify that the Host Bus Adapter (HBA) firmware is at the certified level and is in the VMware Hardware Compatibility Guide. You may need to contact your storage array vendor for instructions on this procedure. For more information, see the Fibre Channel SAN Configuration Guide.
-
Verify that the storage array is listed in the VMware Hardware Compatibility Guide. For more information on confirming hardware compatibility, see Confirming ESX/ESXi host hardware (System, Storage, and I/O) compatibility (1003916).
-
Verify that the initiator is registered on the storage array, and that the storage array is configured correctly. You may need to contact your storage array vendor for further assistance. For more information, see Fibre Channel SAN Configuration Guide.
-
Verify all the fibre channel physical hardware:
-
The fibre switch and the Gigabit Interface Converter (GBIC) units in the switch.
-
The fibre cables between the SAN and the ESX Server.
-
The Host Bus Adapter (HBA).
Note: You may need to contact your hardware vendor for more information about verifying correct functionality.
