4.7 The
probe-scsi
and
probe-scsi-all
test
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:
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.
test ttya
test ttyb
This test ouputs an alphanumeric
test pattern on the system's serial
ports (
ttya
= serial port A,
ttyb
= serial port B).
You must attach a terminal to the
port being tested to observe the
output.
test keyboard
This test executes the keyboard's
selftest.
The four LEDs on the keyboard
should flash on once, and this
message is displayed:
Keyboard
Present
.
test-all
This command tests all devices in the
system that have a selftest program.
Tests are executed in order using the
device tree (viewed with the
show-
devs
command) as reference.
