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.
If you select one of the following, another tree appears on the right. Go to step 3.
Note: If the array already contains the maximum number of physical drives (based on the stripe-unit size), the above Change RAID level actions are not available.
If you select one of the following, go to step 5.
Notes:
After you add the physical drives to your arrays, click Next to review your new logical drive configuration.
Tip: You can expand the tree for another view of the configuration.
Note: Logical drive migration is a lengthy process. You cannot perform any other actions on the affected controller until the migration is complete. The ServeRAID Manager displays a progress indicator in the status bar.
When changing your RAID level, consider the following:
If you have a... | And you want... | Then... |
And in the ServeRAID Manager...
|
RAID level-0 array with two or more drives | RAID level-5 | Add one and only one drive |
Use the Adding physical drives to an existing array panel to define the physical hard disk drive you are adding to the array. |
RAID level-1 array with two and only two drives |
RAID level-5 | Add one and only one drive |
Use the Adding physical drives to an existing array panel to define the physical hard disk drive you are adding to the array. |
RAID level-5 array |
RAID level-0 | Remove the last drive in the array | Use the Reviewing the logical drive migration configuration summary panel to confirm the RAID level change. The ServeRAID Manager automatically removes the last physical hard disk drive from the array. |
RAID level-5 | Do not add or remove a drive | Use the Reviewing the logical drive migration configuration summary panel to confirm the RAID level change. |
