Configuration on Disk

Configuration on Disk saves configuration information both in NVRAM on the Intel RAID

Controller SRCU42X and on the disk drives attached to the SRCU42X controller. If the

SRCU42X controller is replaced, the new SRCU42X controller 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

The Intel RAID Controller SRCU42Xs support drive roaming across channels on the same

SRCU42X controller. Drive roaming lets an Intel Raid SRCU42X controller 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.

Hardware

Note:

Configuration on Disk does not work if you change both the SRCU42X

controller and the SCSI connectors to different connectors on the new

SRCU42X controller. It works only if you make one change at a time.

Note:

Intel RAID Controller SRCU42Xs do not support drive roaming across

channels when cluster mode is enabled.
