Online Capacity Expansion and RAID Level Migration (OCE/ORLM)
OCE/ORLM allows you to add hard disks to an existing RAID array, and/or convert the array to another
RAID level. Data stored on the array is not lost during this procedure. The procedure described below
documents the expansion of a 3-disk 2TB RAID 5 array to a 4-disk, 3TB RAID 5 array.
1.
Start the Web GUI and logon. Click "Maintenance" to the right of the target array.
2.
Select the desired RAID level from the drop down menu (select the existing RAID level if you only
want to add hard disks to the array). Click the OCE/ORLM button.
3.
The Web GUI will display the "Array Transforming" menu (similar to the create array menu).
