If there is storage space available in the subsystem where a logical unit number (LUN) was created, you can extend the size of that LUN.

Important |
Extending a LUN does not automatically extend its file system partition. You must use Disk Manager or a similar tool to extend the file system partition from the server that has access to the LUN. |
Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at http://go.microsoft.com/fwlink/?LinkId=83477.
