142 Configuration: Disk Groups and Virtual Disks

Click

Add

A message prompts you to confirm your selection.

To add the capacity to the disk group, click

Yes

You can also use the Command Line Interface (CLI) on both Windows and

Linux hosts to add free capacity to a disk group.

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.

Virtual Disk Expansion

Virtual disk expansion is a dynamic modification operation that increases the

capacity of standard virtual disks.

NOTE: Snapshot repository virtual disks can be expanded from the CLI or from

MDSM. All other virtual disk types are expandable only from the CLI.

If you receive a warning that the snapshot repository virtual disk is becoming

full, you may expand the snapshot repository virtual disk from MDSM. See

"Snapshot Repository Capacity" on page 162 for step-by-step instructions.

Using Free Capacity

You can increase the capacity of a virtual disk using the free capacity on the

disk group of the standard virtual disk or the snapshot repository virtual disk.

The Free Capacity node, shown in the Logical pane, is a contiguous region of

unassigned capacity on a defined disk group. When increasing virtual disk

capacity, some or all of the free capacity may be used to achieve the required

final capacity. Data on the selected virtual disk remains accessible while the

process for increasing virtual disk capacity is in progress.

Using Unconfigured Capacity

You can increase the capacity of a standard virtual disk or a snapshot

repository virtual disk using the unconfigured capacity when no free capacity

exists on a disk group. An increase is achieved by adding unconfigured

capacity, in the form of unassigned physical disks to the disk group of the

standard virtual disk or the snapshot repository virtual disk. See "Disk Group

Expansion" on page 141.
