Perform a rescan operation each time you reconfigure your storage setup. You can use the vicfg-rescan vSphere CLI or the vSphere Client to perform a rescan. See the ESX Configuration Guide and the ESXi Configuration Guide. The Fibre Channel SAN Configuration Guide discusses rescan on Fibre Channel storage. The iSCSI SAN Configuration Guide discusses rescan on iSCSI storage. When you rescan an ESX/ESXi host, the command returns only an indication of success or failure and no detailed information.
Syntax
vicfg-rescan [] [--help] [--vihost ]
Keys
| switch | description |
| Name of the adapter, for example vmhba1. | |
| connection_options | Specifies the target server and authentication information if required. Run vicfg-rescan –help for a list of all connection options. |
| –help | Prints a help message for each command-specific and each connection option. Calling the script with no arguments or with –help has the same effect. |
| –vihost | -h | When you run a vCLI command with –server pointing to a vCenter Server system, use –vihost to specify the ESX/ESXi host to run the command against. |
Examples
The following example assumes you are specifying connection options, either explicitly or, for example, by specifying the server, user name, and password. Run vicfg-rescan –help for a list of common options including connection options. Refresh adapter registration. This command needs a adapter name to work, for example, vmhba0 or vmhba1:
vicfg-rescan vmhba0
