Installing and Configuring SCSI Drivers

Dell™PowerEdge™4600SystemsUser'sGuide

The SCSISelect Utility

Troubleshooting for NetWare

This section describes how to install and configure the SCSI device drivers included with your system. These device drivers are designed to work with the

Adaptec AIC-7899Ultra160/mSCSI-3 controller on the system board. Each channel of the AIC-7899 supports up to eight internal SCSI hard drives via SCSI

backplane boards.

If you are using an optional RAID controller, see your RAID controller documentation for information on installing your SCSI device drivers.

For instructions on installing SCSI hardware devices such as hard drives, tape drives, or CD-ROM drives, see "Installing a Drive in the Peripheral Bay" in the

Installation and Troubleshooting Guide. After the SCSI devices are installed, install and configure any SCSI device drivers to enable them to communicate with

your operating system.

SCSI device drivers are provided for the following operating systems:

l Microsoft®Windows NT®Server 4.0

l Novell®NetWare®5.x

See "Using the Dell OpenManage Server Assistant CD" for instructions on creating a diskette of drivers for your operating system. For instructions on

configuring the SCSI device drivers, see the documentation that came with your operating system. You may also need to use the SCSISelect utility, discussed

in this section.

The SCSISelect Utility

The BIOS for the integrated Adaptec AIC-7899 SCSI controller includes the menu-driven SCSISelect configuration utility, which allows you to change SCSI

controller settings without opening the system. SCSISelect also contains SCSI disk utilities that let you low-level format or verify the disk media of your SCSI

hard drives.

Starting the SCSISelect Utility

You can start the SCSISelect utility by pressing <Ctrl><a> when the following prompt appears briefly during start-up:

Press<CTRL><A>forSCSISelect™Utility!

The first menu displays the Configure/View Host Adapter Settings and SCSI Disk Utilities options.

Using SCSISelect Menus

SCSISelect uses menus to list options that you can select. To select an option, press the up- and down-arrow keys to move the cursor to the option; then

press <Enter>.

In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing <Esc>. To restore the original

SCSISelect default values, press <F6>.

SCSISelect Default Settings

Default settings for the integrated AIC-7899 SCSI controller are shown in TableC-1. These default settings are appropriate for most PCI systems. Run

SCSISelect only if you need to change any of the default settings.

For situations in which you might want or need to change the settings, see the description of each setting in the following subsections. To change any of the

default settings or to format or verify a disk, see "Using the SCSI Disk Utilities."

NOTE: To change the configuration settings, you must run the SCSISelect utility.
