Create Snapshot Image - Dell PowerVault Manual

Over Threshold The snapshot group repository virtual disk usage is at or beyond its alert threshold.
Any snapshot group in this state causes a Needs-Attention condition to be posted
for the storage array.
Failed The snapshot group has encountered a problem that has made all snapshot images
in the snapshot group unusable. For example, certain types of repository virtual disk
failures can cause a Failed state. To recover from a Failed state use the revive
snapGroup command.

Create Snapshot Image

Description
This command creates a new snapshot image in one or more existing snapshot groups. Before you can
create a snapshot image, you must first have at least one snapshot group into which you can place the
snapshot image. To create a snapshot group use the create snapGroup command.
Syntax
create snapImage (snapGroup="snapGroupName" |
snapGroups=("snapGroupName1"... "snapGroupName2"))
Parameters
Parameter
snapGroup or snapGroups
Notes
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for
the names. Names can have a maximum of 30 characters.
A snapshot image is a logical point-in-time image of the contents of an associated base virtual disk. The
snapshot image is created instantly and records the state of the base virtual disk at that moment. Every
snapshot image is created in the context of exactly one snapshot group. A snapshot group is a sequence
of snapshot images of the associated base virtual disk. A snapshot group has one repository virtual disk
used to save all of the data from the snapshot images. The snapshot images in a snapshot group have a
specific order. The specific order of the snapshot images enables you to manage the snapshot images,
such as restoring a specific snapshot image to the base virtual disk or deleting the snapshot images that
you no longer need.
The result of creating a snapshot image of a consistency group is a snapshot image of every member
virtual disk of the consistency group.
