Extend a LUN

  • Article

Applies To: Windows Server 2008

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 Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).

To extend a LUN

  1. In the console tree, click LUN Management.

  2. In the Results pane, select the LUN you want to extend.

  3. In the Actions pane, click Extend LUN.

  4. In the Extend LUN dialog box, type the new size for the LUN and select the units in megabytes (MB), gigabytes (GB) or terabytes (TB).

  5. To extend the LUN, click OK.
