1.2.1 Drive Migration
Drive migration is the transfer of a set of hard drives in an existing
configuration from one controller to another. The drives must remain on
the same channel and be reinstalled in the same order as in the original
configuration. See the MegaRAID Configuration Software User’s Guide
for more information about drive migration.
