HP Microsoft Windows Server 2003 for Itanium-based Systems manual Configuring a new controller

6.Set the size that you want the logical drive to be, and then click Next.

If the controller has an array accelerator, a screen appears that gives you the option of disabling it for the currently selected logical drive.

NOTE: Disabling the array accelerator for a logical drive reserves use of the accelerator cache for other logical drives on the array. This feature is useful if you want the other logical drives to have the maximum possible performance (for example, if the logical drives contain database information).

7.Select the option that you want, and then click Next.

The gray Configuration View panel shows the configuration that you have chosen.

8.Verify that the configuration is acceptable, and then click Finish.

9.Click the Save icon to commit the changes to the controller, and then click OK on the confirmation alert. (If you click Discard Changes, all changes since the previous save are lost.)

10.To make newly created logical drives available for data storage, use the operating system disk management tools to create partitions and format the drives.
