Identifying shared storage issues with ESX 3.x
Purpose
This article is designed to assist in identifying problems related with the storage subsystem of ESX 3.x.
Resolution
Troubleshooting ESX host storage issues begins with identifying how far reaching (the scope) the problem is. In many cases, a detected problem may be misidentified until the scope has been ascertained.
To identify the scope of the problem:
-
Verify that the storage device cannot be seen by any or a subset of the ESX cluster. If so, select the appropriate storage technology:
-
For Fibre channel, see Troubleshooting fibre channel storage connectivity (1003680).
-
For iSCSI connected by hardware initiator, see Troubleshooting iSCSI array connectivity (1003681).
-
- Verify that no more than a single ESX host cannot see the shared storage. If so, select the appropriate storage technology:
-
For Fibre channel, see Troubleshooting ESX Server connectivity to a fibre channel array (1003682)
-
iSCSI connected by hardware initiator, see Troubleshooting ESX Server connectivity to iSCSI arrays using hardware initiators (1003951).
-
iSCSI connected by software initiator, see Troubleshooting ESX Server connectivity to iSCSI arrays using software initiators (1003952).
-
-
Verify that the LUN is presented and available. For more information, see Troubleshooting LUN connectivity issues (1003955).
-
Verify that the ESX host cannot see the datastore.
-
For Fibre channel or iSCSI, see Troubleshooting ESX Server data store issues (1003964).
