This chapter describes how to install and configure the Dell small computer system
interface (SCSI) device drivers included with your Dell PowerEdge 6300 computer
system. These device drivers are designed to work with the dual Adaptec AIC-7890
low voltage differential (LVD) Ultra2/ Wide SCSI-3 controllers and the Adaptec
AIC-7860 Ultra/Narrow SCSI-3 controller on the system board.
The AIC-7890 controllers support up to six internal SCSI hard-disk drives via a stan-
dard SCSI backplane board while the AIC-7860 supports up to three externally
accessible SCSI devices in the system’s external drive bays, such as the CD-ROM and
a tape drive unit.
The Dell PowerEdge 6300 system can support up to two 1-inch SCSI drives in the
external drive bay with the optional removable drive cage.
The AIC-7890, AIC-7860, and the optional AHA-2940U2W SCSI controller card are all
part of the Adaptec 78xx series of SCSI controllers, and all use the 78xx series of SCSI
device drivers provided by Dell. The Adaptec SCSI basic input/output system (BIOS),
which is stored in your computer system’s flash memory or on the optional
AHA-2940U2W SCSI controller card, links these SCSI device drivers to the AIC-7890
and AIC-7860 SCSI controller chips or the optional AHA-2940U2W SCSI controller card.
If you are using an optional Dell PowerEdge Expandable RAID Controller, refer to
either of the following sections, “Installing SCSI Drivers for a Dell PowerEdge Expand-
able RAID Controller in Windows NT 4.0” or “Installing SCSI Drivers for a Dell
PowerEdge Expandable RAID Controller in Novell NetWare 4.11.” You can also refer to
your Dell PowerEdge Expandable RAID Controller documentation for information on
installing your SCSI device drivers.
For instructions on installing SCSI hardware devices such as hard-disk drives, tape
drives, or CD-ROM drives, trained service technicians should see Chapter 9, “Install-
ing Drives in the External Bays,” and Chapter 10, “Installing Hard-Disk Drives,” in your
Installation and Troubleshooting Guide. After the SCSI devices are installed, you need
to install and configure one or more SCSI device drivers so that your SCSI devices can
communicate with your operating system.
