How can I increase the capacity of a virtual disk?

You can use Intel® RAID Web Console 2 to increase the capacity of an existing virtual disk by adding physical disk drives to it. In order to add physical drives, you must be logged on to the system in All Access mode.

Before you change a virtual disk’s capacity, back up the data on the virtual disk.

To increase the capacity of a virtual disk, follow these steps:

  1. User Logical View and select a Drive Group icon in the left panel, and then select Go To -> Drive Group -> Modify Drive Group.

    The Modify Drive Group window is displayed.

    The following screen appears:
