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:

Preparation
Connect a cable to the system"s
TPE port and to a TPE hub or the
test will fail the external loopback
phase. If the tpe-link-test?
parameter is false (disabled), the
external loopback test will appear
to pass even if a cable is not
connected.
A cable must be attached to the
system and to an Ethernet tap or
hub or the external loopback test
will fail.
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.
