figuration parameter
diag-switch?
is
true
for each test, a message
is displayed on a terminal connected to the serial I/O interface A. If the
system does not work correctly, error messages are displayed which indi-
cate the problem. After POST the OpenBoot firmware boots an operating
system or enters the Forth monitor, if the NVRAM configuration parame-
ter
auto-boot? is false .
The Forth Monitor includes several diagnostic routines. These on-board
tests let you check devices such as network controller, SCSI devices,
floppy disk system, clock, keyboard and audio. User installed devices can
be tested if their firmware includes a self-test routine.
The table below lists several diagnostic routines followed by examples
for each of these routines:
Examples:
SCSI bus To check the SCSI #1 for connected devices enter:
Table 22 Diagnostic routines
Command Description
probe-scsi
Identifies devices connected to the primary SCSI bus
probe-scsi-all [ device-path]
Performs probe-SCSI on all SCSI buses installed in
the system below the specified device tree node. If
device-path
is omitted, the root node is used.
test device-specifier Executes the specified device’s self-test method.
device-specifier
may be a device path name
or a device alias.
Example:
• test net – test network connection
test-all [ device-specifier]
Tests all devices that have a built-in self-test method
and that reside below the specified device tree node.
If
device-path
is omitted, the root node is used.
watch-clock
Monitors the clock function.
watch-net-all
Monitors network connection via all Ethernet inter-
faces installed in the system.
watch-net
Monitors network connection via primary Ethernet.
