6.6.3.3 Access Additional Space
After an array has been transformed to a larger size, use the operating system tools to access the
additional space.
There are several possible methods for expanding the existing file system on an array that has been
transformed to a larger size:
 Microsoft
®
provides a command prompt utility called Diskpart.exe that can expand any NTFS
file system without requiring a reboot. The Diskpart.exe utility version to use depends on the
version of Windows being run. The Diskpart.exe utility can be found on the CD that comes
with some versions of Windows, or at the Microsoft website (http://www.microsoft.com) for
others. Use the correct version for the operating system.
 For arrays formatted with FAT32, use a third-party application, such as PartitionMagic from
PowerQuest Corporation.
6.6.4 Restore (Rebuild) Arrays
With the Restore task, a redundant-type array whose state has changed to Critical can be restored
(rebuilt) in one of two ways:
 By assigning a dedicated spare to the array.
 By creating a global spare or by using an existing global spare. (An existing global spare
automatically starts restoring a redundant-type array after the array’s state changes to Critical.)
An array in an Offline state cannot be restored. This means that non-redundant arrays (Volume,
RAID0) cannot be restored: when a single disk in a non-redundant array fails, the array state
changes to Offline.
Note: If a Critical redundant array that is being restored loses a second disk (RAID1 or RAID5),
or loses a second disk in the same mirror set (RAID10), the Restore task fails. The array
must be re-created from backup storage data.
6.6.4.1 Before You Begin
 Make sure that the disk chosen as the dedicated spare or global spare has sufficient available
capacity to restore the array. The capacity of the spare disk must be equal to or larger than the
capacity of the smallest disk in the critical array.
 Know how to create a global or dedicated spare. See Section 6.6.13, Add or Remove
Dedicated Spares, on page 82 or Section 6.6.14, Add or Remove Global Spares, on page 83.
6.6.4.2 Restore a Critical Array
1. In the Array View section, select the critical array.
2. At the Disk List section, select a disk.
3. At the Disk menu, select Spare/Identify. Options for Disk Device displays in the Disk List
panel. Perform one of the following actions:
