Disk Group And Virtual Disk Expansion; Disk Group Expansion - Dell PowerVault MD3220 Owner's Manual

Disk Group and Virtual Disk Expansion

Adding free capacity to a disk group is achieved by adding unconfigured
capacity on the array to the disk group. Data is accessible on disk groups,
virtual disks, and physical disks throughout the entire modification operation.
The additional free capacity can then be used to perform a virtual disk
expansion on a standard or snapshot repository virtual disk.

Disk Group Expansion

To add free capacity to a disk group:
1 In the AMW, select the Logical tab.
2 Select a disk group.
3 Select Disk Group Add Free Capacity (Physical Disks).
The Add Free Capacity window is displayed. Based on the RAID level, and
the enclosure loss protection of the current disk group, a list of unassigned
physical disks appears.
NOTE:
the expansion enclosure has enclosure loss protection, Display only physical disks
that will ensure enclosure loss protection appears and is selected by default.
4 in the Available physical disks area, select physical disks up to the allowed
maximum number of physical disks.
NOTE:
within a single disk group or virtual disk.
5 Click Add.
A message prompts you to confirm your selection.
6 To add the capacity to the disk group, click Yes.
You can also use the Command Line Interface (CLI) on both Windows and

information.
After the capacity expansion is completed, additional free capacity is available
in the disk group for creation of new virtual disks or expansion of existing
virtual disks.
