Logical Drive Migration Administration
The logical drive migration (LDM) feature dynamically changes the current logical drive structure.
You can use this feature 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 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 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 controller changes the state of the SYS drive back to FRE.
