Description

Property

The status of the VDG. Possible values:

Normal—All members of the VDG have normal status.

Partial—One or more of the VDG members has partial status.

Status

The states of the VDG members. Possible values:

Normal—Each virtual disk is in normal operational state.

Delete—Each virtual disk is being deleted. The VSM server marks the virtual
disk for deletion and waits for an acknowledgement from all the hosts that use
it. Once acknowledged, the VSM server deletes the virtual disk and marks the
capacity that it used as free space available for allocation. When the deletion
is complete, the virtual disk disappears from the virtual disk list.

State

Yes indicates that the VDG is defined as a cluster resource. This setting tunes the
SVSP system behavior when the virtual disk is permitted to multiple hosts (configured
as a resource in a cluster application). For a description of configuring virtual disks
for cluster applications, see

Defining virtual disks as clustered

” on page 119.

All VDG members must be configured as either clustered or non-clustered. You
cannot configure clustered and non-clustered members in one VDG.

Data Path Module/VSM—If the VDG is presented to UDH hosts, the Data Path Module tab displays
the primary and secondary DPM settings for the VDG and the active DPM.

Security—Shows which permissions are assigned to users and user groups for managing the VDG.

Hierarchy—Shows the relationship between the selected virtual disk and any snapshot PiTs and
snapshots for which the VDG is a source element.
