Appendix C. Connecting SCSI Hard Disk Drives to the Adapter

The RAID adapter connects to a hard disk drive through one of two possible SCSI channels. The connected hard disk drives can be inside the host system unit, outside the system unit in a hard disk drive enclosure, or both. Each hard disk drive on a SCSI channel must have a unique SCSI ID of 0 through 6,

The addressing scheme is in hex notation. Address 7 is reserved for the adapter and is not to be used for another SCSI hard disk drive. Each of the SCSI channels (0 and 1) is assigned a channel ID. The channel

and SCSI ID are used to fully identify a hard disk drive connected to the adapter. For optimum overall

performance and data protection, distribute hard disk drives evenly across the two available channels.

Determining Current SCSI Hard Disk Drive Addresses

Hard disk drive backplanes or external subsystems automatically set the SCSI address for you. Refer to the documentation for your system or external subsystem for their locations. For future reference, be sure

keep a list of all the SCSI addresses you use and the channels to which they are connected.

determine the SCSI addresses of any installed hard disk drives, start the RAID manager program and

list the attached physical drives. For an AIX system, see PCI-X SCSI RAID Controller Reference Guide for

AIX, order number SA23-1323. For a Linux system, see PCI-X SCSI RAID Controller Reference Guide for Linux, order number SA23-1327. If you have another operating system installed, refer to your operating

system documentation for the correct procedures.

Notes:

The priority of SCSI addresses for the PCI-X Dual Channel Ultra320 SCSI RAID Adapter is not in sequential order. The order of priority is 7 through 0 and 15 through 8.
