You can add one or more disks to a RAID group in the storage pool.
Adding disks to a RAID 1 group changes the RAID type of the group to RAID 5.
The storage pool contains at least one RAID 1, RAID 5, or RAID 6 group.
The status of the RAID group that you want to expand is Ready.
The Storage Pool Management window opens.
The Expanding Storage Pool window opens.
A confirmation message appears.
Clicking OK deletes all data on the selected disks.
QTS starts rebuilding the RAID groups. The capacity of the new disks appears as free space after RAID rebuilding is completed.
