Logical Drive Migration
The Logical Drive–Migration tab enables you to:
• Change the RAID level of an existing logical drive
• Add more physical drives to a logical drive while keeping the same RAID
level
Migration is not available for JBOD.
You can change the RAID level of a logical drive with certain combinations of
RAID level and number of physical drives, as described in the table below.
You can add physical drives while keeping the same RAID level only to a RAID 0
logical drive, as described in the table below.
For more information, see “Migration” on page 91.
You can set up an Migration to begin immediately (on demand) or schedule a
Migration for a time when there is less demand on the RAID system.
