After you create a LUN, you cannot change the provision setting (thin or thick), but you can expand the size of the LUN.
Expansion is instant, regardless of the data size, but you first need to disconnect all users that are connected to the LUN. You do this by removing the LUN from the LUN group to which the users have access. For more information, see the How do I remove a LUN from a LUN group on my ReadyDATA storage system?
To expand the size of a LUN:
1. Select Shares.
2. Click the Data Set button (with four cubes, 
).
The Shares screen displays (see the image in Step 3).
3. Select the LUN for which you want to expand the size.
The color of the LUN turns purple:
4. Right-click a share or LUN.
A pop-up menu displays:
5. Select Expand.
The Expand LUN pop-up screen displays:
6. Enter the following settings:
-
New Size. Specify the new size of the LUN. The maximum size that you can allocate to the LUN is stated above the New Size field.
-
Unit. Select the unit of measurement from the drop-down list (MB, GB, or TB).
7. Click Expand.
The new LUN size takes effect.
8. Add the LUN to the LUN group to which it belonged before the expansion. For more information, see the How do I create a LUN group and assign LUNs to LUN groups on my ReadyDATA storage system?
User access to the LUN is restored.
Note: You can also expand a LUN from the Properties pane by clicking the Expand size link on the Properties pane.
