Starting to Build a RAID System Drive

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 ASUS PCI-DA2100/-DA2200 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.
NOTE:
A "Logical Drive" is a set of drives grouped together to operate under a
given RAID level and appears as a single contiguous drive. The ASUS PCI-
DA2100/-DA2200 controller is capable of grouping connected drives to as
many as 8 logical drives, each configured on the same or different RAID
levels. A logical drive can be further divided into a maximum of 8
"Partitions". During operation, the host sees an unpartitioned logical drive
or a partition of a partitioned logical drive as one single physical drive.
