4.7 The probe-scsi and probe-scsi-all test
Table 4-5 Selected On-Board Diagnostics Tests
Description
This test ouputs an alphanumeric
test pattern on the system's serial
ports (ttya = serial port A,
ttyb = serial port B).
This test executes the keyboard's
selftest.
This command tests all devices in the
system that have a selftest program.
The probe-scsi test sends an inquiry command to internal and external SCSI
devices connected to the Sun Ultra 1 Series on-board SCSI interface. If a SCSI
device is connected and powered up the target address, unit number, device
type, and manufacturer's name is displayed.
Example:
ok probe-scsi
Target 0
Unit 0 Disk
Target 1
Unit 0 Disk
Target 6
Unit 0 Removable Read Only device
5301TASUN4XCD1735
The probe-scsi-all test sends an inquiry command to all SCSI devices on
all the SCSI host adapters installed in the system. The first identifier listed in
the display is the SCSI host adapter's address in the system's device tree,
followed by the SCSI device identification data.
Troubleshooting Procedures
Preparation
You must attach a terminal to the
port being tested to observe the
output.
The four LEDs on the keyboard
should flash on once, and this
message is displayed: Keyboard
Present.
Tests are executed in order using the
device tree (viewed with the show-
devs command) as reference.
