7.9 Changing the RAID Level of a Logical Drive

If your storage needs or application requirements change, you can change, or migrate, the RAID level of your logical drives to another, more suitable, RAID level. You might want to change the RAID level to add redundancy, further protect your data, or to improve data availability for speedier access. See Selecting the Best RAID Level for more information.

To change the RAID level of a logical drive:

  1. In the Enterprise View, select a controller, then select the logical drive that you want to migrate.
  2. On the ribbon, in the Logical Device group, click Expand/Migrate.

    The Expand/Migrate Logical Device wizard opens.

  3. Click Migrate, then click Next.
  4. Select a new RAID level, then click Next. Only valid RAID level options are offered.
  5. Select the sub array count for RAID 50 and RAID 60.
  6. Select the logical drive stripe size from the drop-down list.
    Note: The default stripe size usually provides the best performance.
  7. Click Next.
  8. Review the summary of logical drive settings. To make changes, click Back.
  9. Click Finish.
    The logical drive is reconfigured and migrates to the new RAID level.
