The following figure is a basic flowchart when configuring a RAID
system. Hardware installation must be completed before any
configurations take place.
When power is turned on, the AA-3102RS RAID controller scans all
the hard drives that are on all the drive channels. If a hard drive was
connected after the controller completes initialization, use the "SCAN
SCSI DRIVE" function to let the controller recognize the newly added
hard drive and configure it as a member of a logical drive or a spare
drive.
In accordance to your requirement, configure a logical drive to contain
one or more hard drives based on the desired RAID level, and partition
the logical drive into one or several partitions. Map each partition as
one system drive (LUN). The host SCSI adapter will recognize the
system drives after re-scanning the host SCSI bus.
Since the controller is totally operating system independent, the
operating system of the host computer will not be able to find out
whether the attached devices are physical hard drives or virtual
system drives created by the RAID controller.
