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.
SCSI ID number
. The SCSI ID number is a unique number assigned to the SCSI
controller. This must be a unique number. The standard controller numbering
scheme is for controllers to be SCSI ID 7.
SCSI bus number
. The SCSI bus number indicates whether the controller is first
or second in the system. The first controller is tied to SCSI bus 0, and the second
controller is tied to SCSI bus 1.
2. SCSI ID
The SCSI ID number is a unique number you assign to each SCSI device installed
in the system. This is usually done via jumpers on the device or on the
StorageWorks backplane.
3. Device Type
The device type displays whether the device is a hard disk, CD-ROM, scanner, or
other type of device.
4. 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 the way storage is managed under those file systems.
This information is left blank if it is not applicable to a device, for example, a
scanner.
5. Description
This is the name and model of the device as recorded in the device’s firmware.
