Fields in the hard disk configuration menu include:
Physical disk ID
. The physical disk ID is based on the SCSI ID. The disk with
the lowest SCSI ID is disk 0; the disk with the next lowest SCSI ID is disk 1, and
so on.
Controller
. The controller is the brand and model of SCSI chip used on the
SCSI controller.
Controller number
. The controller number is based on how many SCSI
controllers of a particular type are installed in the system. The first controller of a
type is always numbered 0. For example, if two NCR 810 controllers and one
QLogic controller existed in a system, they would be numbered as follows:
First NCR 810 = NCR810 #0, Second NCR 810 = NCR 810 #1, QLogic =
QLogic #0
SCSI ID number
. The SCSI ID number is a unique number you assign to each
SCSI device installed in the system. This is usually done via jumpers or a thumb
wheel attached to the drive housing or by jumpers supplied on the StorageWorks
backplane.
Size
. This is the raw capacity of the drive. Formatting the drive with different
file systems

for example, FAT and NTFS

may result in different usable sizes
because of the differences in how storage is managed under those file systems.
Drive manufacturer ID
. This line identifies the type of drive and the
manufacturer, as well as the firmware revision of the drive.
