Scanning Storage Adapters
You must perform a rescan operation each time you reconfigure your storage setup. You can scan using the vSphere Client, the vicfg-rescan vCLI command, or the esxcli storage core adapter rescan command.
esxcli storage core adapter rescan supports the following additional options:
-a|--all or -A|--adapter=<string> – Scan all adapters or a specified adapter.
-S|--skip-claim – Skip claiming of new devices by the appropriate multipath plugin.
-F|--skip-fs-scan – Skip filesystem scan
-t|--type – Specify the type of scan to perform. The command either scans for all changes ( all) or for added, deleted, or updated adapters (add, delete, update)
vicfg-rescan supports only a simple rescan operation on a specified adapter.
To rescan a storage adapter with vicfg-rescan
Run vicfg-rescan, specifying the adapter name.
vicfg-rescan <conn_options> vmhba1
The command returns an indication of success or failure, but no detailed information.
To rescan a storage adapter with ESXCLI
The following command scans a specific adapter and skips the filesystem scan that is performed by default.
esxcli <conn_options> storage core adapter rescan --adapter=vmhba33 --skip-claim
The command returns an indication of success or failure, but no detailed information.
