Changing the RAID Level of an Array

Use this option to change the RAID level on a selected array. Using this option will change the RAID level of every logical drive that comprises the array. Performance may be slightly affected during the operation.

Important:

RAID Level Drive Number Constraints

There are drive number requirements for choosing a particular RAID level. If you attempt to change to a RAID level for which you do not have the appropriate number of drives in the array, an error message is displayed.
RAID level Drive Number Requirements
RAID 0
  • You are limited to a maximum of 20 drives in the array
RAID 1
  • You must have an even number of drives in the array. If you do not have an even number of drives and you have some remaining unassigned drives, use the Array>>Add Free Capacity option to add additional drives to the array, then retry the operation.
  • You are limited to a maximum of 30 drives in the array
RAID 3 or 5
  • You must have a minimum of 3 drives in the array
  • You are limited to a maximum of 20 drives in the array

How to Change the RAID Level

1 Select the array in the Logical View; then select either (1) the Array >> Change RAID Level pull-down menu option, or (2) Change RAID Level from the right-mouse pop-up menu.

Result: The RAID level fly-out menu is displayed.
2 Select the desired RAID level ( RAID 0, RAID 1 , RAID 3, or RAID 5). The currently selected option is designated with a dot.

Result: The Change RAID Level Confirmation dialog is displayed.
3 Select Yes.

Result: The RAID level operation begins. The logical drive icons under the selected array in the Logical View show a status of Operation in Progress until the operation is complete. To view the progress or change the priority of the modification operation, select a logical drive in the array, then select Logical Drive >> Properties. Note that the priority is set on an individual logical drive basis.
