Backing Up Your Data with Mirrored Volumes
72 Snap Server 700i Series User’s Guide
Extending a Mirrored Volume
You can increase the size of a volume, up to the space available in its pool. If you
want to increase the size of a mirrored volume, the mirror also has to have enough
space in its pool to be extended by the same amount.
To extend a mirrored volume:
1
In the Enterprise View, select
the iSCSI Storage Host you
want.
2
In the Volumes View, right-
click the mirrored volume
you want, then select
Extend
volume
.
The Extend Volume window
opens.
3
By default, the Extend By
field is set to the space
available in the pool. Adjust
the number to suit your
requirements, then click
OK
.
The Job Manager opens (see
page 109) and the job begins.
When the job is complete,
the volume appears in the
Volumes view with its new
size.
Changing Mirror Priorities
This section describes how to change the priority of a mirrored volume. When you
change the priority, the mirror (or mirror plex ) becomes the volume (or mirror
manager ) and the original volume becomes the mirror.
To change mirror priorities:
1
In the Enterprise View, select the iSCSI Storage Host you want.
2
In the Volumes View, right-click the mirrored volume you want, then select
Modify mirror
.
The Modify Mirror window opens.
3
In the Plex Properties panel, select the existing mirror manager.
Right-click
