Configuration on Disk
Configuration on Disk saves configuration information both in NVRAM on
the MegaRAID 320 storage adapter and on the disk drives attached to
the storage adapter. If the storage adapter is replaced, the new storage
adapter detects the actual RAID configuration from the configuration
information on the drives. This maintains the integrity of the data on each
drive, even if the drives have changed their target ID.
1.3.3
Drive Roaming
The MegaRAID 320 storage adapters support drive roaming across
channels on the same storage adapter. Drive roaming lets a MegaRAID
storage adapter detect the actual RAID configuration, maintaining the
integrity of the data on each disk drive, even if the disk drives have
changed channels and/or target ID.

Note:
Configuration on Disk does not work if you change both the
storage adapter and the SCSI connectors to different
connectors on the new storage adapter. It works only if you
make one change at a time.
Note:
MegaRAID 320 storage adapters do not support drive
roaming across channels when cluster mode is enabled.
