Logical Drive Migration Administration
The logical drive migration (LDM) feature dynamically changes the current logical drive structure.
You can use this procedure to change the RAID level, increase the free space in a disk array, or change
the size of a logical drive.
To use the LDM feature, you must have at least two logical drives available:
one free (FRE) logical drive and one source logical drive that is in the okay (OKY) state.
During the LDM procedure, the ServeRAID adapter or controller
changes the state of the FRE logical drive to SYS, then, temporarily uses the SYS drive to perform the migration.
When the migration procedure completes, the ServeRAID
adapter or controller changes the state of the SYS drive back to FRE.
Change RAID Levels:
You can change (migrate) the RAID levels of currently defined
logical drives. To use the Change RAID Level feature, all of the logical drives within the array
must be the same RAID level.
The ServeRAID adapters and controllers support changing
RAID levels as follows:
A screen similar to the following appears.
NOTE: The affected logical drives appear, based on the migrating option you select.
