You can use the vSphere Client to map a SAN LUN to a datastore and manage paths to your mapped LUN.

Additional tools available to manage mapped LUNs and their RDMs include the vmkfstools utility and other commands used with the vSphere CLI. You can use the vmkfstools utility to perform many of the same operations available through the vSphere Client.

You can also use common file system commands in the service console.
