1.3.2 Configuration on Disk
Configuration on Disk saves configuration information both in NVRAM on the Intel
®
RAID
Controller SRCU42E and on the disk drives attached to the RAID Controller SRCU42E. If
the RAID Controller SRCU42E is replaced, the new RAID Controller SRCU42E 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.
Note: Configuration on Disk does not work if you change both the RAID Controller
SRCU42E and the SCSI connectors to different connectors on the new RAID
controller. It works only if you make one change at a time.
1.3.3 Drive Roaming
The RAID Controller SRCU42E supports drive roaming across channels on the same RAID
Controller SRCU42E. Drive roaming lets an Intel Raid RAID Controller SRCU42E 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: The RAID Controller SRCU42E does not support drive roaming across
channels when cluster mode is enabled.
