The Windows NT 4.0 operating system supports online logical drive capacity
extension. Some operating systems also support offline capacity extension. Before
extending logical drives, check the operating system documentation for current
information, or contact your operating system vendor.

NOTE: The extension process takes about 15 minutes per gigabyte. Data can still be read
from or written to any logical drive on the controller during an extension, although performance
might be reduced. However, a controller can perform only one expansion, extension, or
migration at any given time.

To extend the capacity of a logical drive:

1. Back up all data on the array. Although array expansion is unlikely to cause data

loss, observing this precaution will provide additional data protection.

2. If you are extending the capacity while offline:

a. Restart the server from the software CD provided in the controller kit.

b. Open ACU from the CD.

3. Select the logical drive in the Logical Configuration View window.

4. Click Extend in the Logical Drive box.

The Extend Logical Drive screen displays the current capacity and overhead of
the selected logical drive. The unshaded region on the slider scale shows the free
capacity on the array that is available for extension.

5. Move the slider control to increase the size of the logical drive.

NOTE: You cannot reduce the size of the logical drive from this screen.

6. Click Done to return to the main ACU screen.

7. To save the logical drive settings, click Controller on the menu bar and select

Save Configuration.

A progress bar in the lower right-hand corner of the screen shows the status of
the extension process.
