Migrating a Logical Drive

The Logical Drive–Migration tab enables you to:

•

Change the RAID level of an existing logical drive

•

Add physical drives to a logical drive while keeping the same RAID level.
This action is also called Expansion

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.

Important

Migrating to some RAID levels might require you to add physical
drives. Add drives that are the same size or larger than those in
the current logical drive.
