You can determine which SCSI IDs are currently in use by looking
under the “
H/W Path
” heading. In the example display, the
H/W Path
for the built-in SCSI interface is
8/16/5
. For devices connected to the
built-in SCSI bus, such as disks, the fourth number is the SCSI ID for
that device. For example, the listing
8/16/5.2.0
tells you that there
is a SCSI device (a disk) currently using ID 2 on the SCSI bus.
NOTE
Never use SCSI address 7 for any device. Address 7 is reserved for the
SCSI controller.
Using Device Files
Device files are special files that tell your system which pathway to use
through the system hardware when communicating with a specific
device and what kind of device it is.
NOTE
The
device
file
names
depend
on
the
naming
conventions
of
your
particular system.
To determine what device files are available for use with your disk drive,
use the following procedure:
1.
In a terminal window, become
root
and type the following command
at the prompt and press
Enter
:
sam
The System Administration Manager (SAM) window opens.
2.
Double click on the
Disks and File Systems
icon. The Disk and File
Systems window opens.
3.
Click on a desired disk drive in the list of disk devices to select it.
4.
Select the
Actions
menu and then select the menu item
