User`s guide

When you change the RAID level of an existing pool, stored data is migrated across
existing and new disk drives.
This table lists supported migrations:
You can also migrate from RAID 1 or RAID 5 to RAID 0. If the pool has a spare
drive associated with it, the RAID 0 pool retains the spare drive.
Note
Migrations that do not involve a change in RAID level are also supported in
RAID 0, RAID 1,
RAID 5, and RAID 6. See “Adding Capacity to a Pool” on page 96
for more information.
To change the RAID level of a pool:
1 In the Logical Devices View, select the pool you want.
2 In the Actions menu, click Expand or migrate pool.
The wizard opens to the Choose RAID Level window.
3 Select a new RAID level. (Only supported RAID levels are listed.)
4 Click Next.
The Modify Pool window opens.
5 If prompted, select additional disk drives to support the new RAID level.
6 Click Next, then review the pool settings.
7 Click Apply, then click Yes to change the pool’s RAID level.
The RAID level is changed.
Moving a Pool to Another iSCSI Storage Appliance
You can move an existing pool to another iSCSI Storage Appliance, if required.
When you move a pool, you transfer its RAID data and transfer its disk drives to the
new appliance.
