Discover storage on the host
When you add new LUNs, you must manually rescan the associated disks to discover them. The host does not automatically discover new LUNs.
LUNs on your storage system appear as disks to the Windows host.
Log on as an administrator.
To discover the storage, run the following command from a Windows command prompt.
# echo rescan | diskpart
To verify the addition of new storage, run the following command.
# echo list disk | diskpart
