Changing RAID Levels



Changing RAID Levels
 
You can change (migrate) the RAID levels of currently defined logical drives. Depending upon the current RAID level, you might need to add or remove a hard disk drive before you can change the RAID level.

To use the Change RAID Level feature, all of the logical drives within the array must be the same RAID level.


The ServeRAID controller supports changing RAID levels as follows:

Change two RAID level 0 logical drives to RAID level 5 by adding one hard disk drive
Change two RAID level 1 logical drives to RAID level 5 by adding one hard disk drive
Change from RAID level 5 to RAID level 0 by removing one hard disk drive.

To change the RAID level:

  1. Click on the   icon on the tool bar or select Manage Disk Arrays from the Advanced pull-down
     menu, then, select Logical Drive Migration.

     A screen similar to the following appears.

     
  2.  Select Change RAID Level, then click on OK

     
  3.  Select a migrating option from the pull-down list.

    Note: The affected logical drives appear based on the migrating option selected.

  4.  Click on OK to proceed, then, click on OK to verify the operation.
  5.  Select a Ready (RDY) drive to add to the array if you are migrating to RAID level 5.

    Note: If you are migrating to RAID level 0, the last drive defined in the array becomes RDY.
