Migration to RA4000 from SCSI Technology
Incompatibilities in bus and drive mapping exist between Compaq ProLiant Storage Systems and
the RA4000. For this reason, data stored on hard drives in a ProLiant Storage System connected
to a Smart Array Controller cannot be migrated directly to an RA4000. Instead, migrating stored
data from an existing storage system to an RA4000 requires a full backup and restore operation.
Refer to www.compaq.com for details about migrating to an RA4000 from a Compaq ProLiant
Storage system using the Compaq SMART Array controllers.
