Backing Up Your Data with Mirrored Volumes
Chapter 6 Protecting Your Data 71
Creating a Mirrored Volume
You can mirror a new volume or an existing volume.
Note
The MPIO DSM driver (see page 17) must be installed on the iSCSI Storage
Host that’s accessing the volume. Without the MPIO driver, automatic failover can’t
occur.
To create a mirrored volume:
1
In the Volumes View, right-click the volume you want to mirror, then select
Create remote mirror plex
.
The Define Remote Mirror Plex window opens.
2
In the Pools list, select the pool in which you want to create the mirror.
Only pools with sufficient space that also reside in a different iSCSI Storage
Appliance than the original volume appear in the Pools list.
3
(Optional) Adjust the capacity display units (MB, GB, TB).
4
Click
Next
, review the mirror settings, then click
Apply
.
The Job Manager opens (see page 109) and the job begins.
When the job is complete, the volume and its mirror can be used.
Note
If Adaptec Storage Manager displays a message that indicates there is
insufficient space to create a mirror plex, press
F5
then try creating the mirror plex
again.
