# Changing the RAID level

Note: This action is not supported on the integrated RAID controller.

You can change the RAID levels of currently defined logical drives. To use "Change RAID level," all of the logical drives within the array must be the same RAID level.

Notes:
  1. If the logical drive is RAID level-00, 10, 1E0, 50, or 5EE, you cannot change the logical drive to another RAID level. If the logical drive is RAID level-0, 1, 1E, 5, or 5E, you cannot change the logical drive to RAID level-00, 10, 1E0, or 50.
  2. (Cluster and failover configurations only) A logical drive will not failover while undergoing logical-drive migration.

1. In the tree, click (array).
2. Right-click Logical-drive migration the appropriate Change RAID level.

   Note: If the array already contains the maximum number of physical drives (based on the stripe-unit size), the following actions are not available:

   - Change RAID level from RAID 0 to RAID 5
   - Change RAID level from RAID 1 to RAID 5
3. If you click one of the following:
   - Change RAID level from RAID 0 to RAID 5
   - Change RAID level from RAID 1 to RAID 5
   The Configuration wizard opens with the "Create arrays" window. Add the physical drives to the array; then, review and apply your new configuration.

   If you click Change RAID level from RAID 5 to RAID 0, the Configuration wizard automatically removes the physical drives and opens the "Configuration summary" window. Review and apply the new configuration.

   If you click Change RAID level from RAID 5E to RAID 5, the Configuration wizard does not add or remove a physical drive. Instead, the wizard changes the spare space to become free space. Use this free space to create a new logical drive.
