6 Chapter 6 Configuring RAID 6.1 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. Create Logical Drive Partition Logical Drive Map Host LUN (System Drive) 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 PCIDA2100/-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. ASUS PCI-DA2100/PCI-DA2200 User's Manual 53
