Understanding SCSI
Preparing SCSI Devices for Installation
When preparing to install SCSI devices, make sure to
■
Check the SCSI IDs. Ensure that the SCSI Card 2930CU and
each SCSI device you want to connect to it has a unique SCSI
ID. See
SCSI IDs
on page A-2
for more information.
■
Use only high-quality SCSI-2 cables to ensure reliable data
transfer. See
Chapter D,
Obtaining SCSI Cables
for more
information.
■
Terminate the ends of the SCSI bus. The SCSI device at the end
of each cable, or the end of the cable itself, must have a
terminator installed or enabled. Terminators must be disabled
or removed from SCSI devices that will be connected between
the ends of the SCSI cable. See
Terminating the SCSI Bus
on
page A-3
for more information.
■
You may need to install the manufacturer’s proprietary device
drivers if you use SCSI devices other than hard disk drives and
CD-ROM drives. (Refer to your device’s documentation.)
Using SCSI Devices
Hard Disk Drives
Every SCSI hard disk drive connected to you SCSI card must be
physically low-level formatted, partitioned, and logically
formatted before it can be used to store data. Refer to your
computer and operating system documentation for instructions.
Caution:
A low-level format destroys all data on the drive. Be
sure to back up your data before performing a low-level format.
If you are booting from a SCSI hard disk drive, make sure the Hard
Disk (or Drives) setting in your computer’s CMOS setup program is
set to
None
or
No Drives Installed
. Refer to your
computer and
operating system documentation for instructions.
If both SCSI and non-SCSI (for example, IDE) hard disk drives are
installed, the non-SCSI hard disk drive is usually the boot drive.
