Configure/View Host Adapter Settings; Scsi Disk Utilities - Dell PowerEdge 4300 User Manual

3-2 Dell PowerEdge 4300 Systems User's Guide
The AIC-7890 host adapter supports up to six 1.6-inch or 1-inch internal SCSI hard-disk
drives via a standard SCSI backplane board. The AIC-7860 host adapter supports up to
three externally accessible SCSI devices, such as the CD-ROM drive and a tape drive
unit, in the system's external drive bays.
The Dell PowerEdge 4300 system can support up to two 1-inch SCSI drives in the
external drive bay using the optional removable drive cage.
The AIC-7890 and AIC-7860 host adapters and the optional AHA-2940U2W host
adapter are all part of the Adaptec 78 xx series of SCSI controllers, and all use the 78 xx
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
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, the corre-
sponding SCSI device drivers are installed at the same time as the SCSI device drivers
for the AIC-7890, AIC-7860, and AHA-2940U2W host adapters. You can also refer to
your Dell PowerEdge Expandable RAID Controller documentation for information on
installing your SCSI device drivers. For instructions on configuring the SCSI device
drivers for RAID controllers, see the appropriate sections in this chapter.
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 the
Installation and Troubleshooting Guide . After the SCSI devices are installed, you may
need to install and configure one or more SCSI device drivers so that your SCSI
devices can communicate with your operating system.
The BIOS for the built-in AIC-7890 and AIC-7860 SCSI controllers includes the menu-
driven SCSI Select configuration utility, which allows you to change SCSI controller
settings without opening the computer. SCSI Select also contains SCSI disk utilities
that let you low-level format or verify the disk media of your SCSI hard-disk drives.
You can start the SCSI Select utility by pressing <Ctrl><a> when the following prompt
appears briefly during start-up:
Press <CTRL><A> for SCSISelect (TM) Utility.
The first menu displays two options:
