Type of Tests Description
test disk
Tests internal or external SCSI disks which have a self diagnostic
test disk0
program contained in the drive controller. The drive must be
test disk1
spinning before this test is executed or the test will fail. Enter a boot
test disk2 <disk alias>
command to cause the drive to spin up. (
disk
and
disk0
=
test disk3
SCSI target 3,
disk1
= SCSI target 1,
disk2
= SCSI target 2,
disk3
=
SCSI target 0.)
test cdrom
Performs a selftest diagnostic on the CDROM drive. The CDROM must
be set to SCSI target 6 and have a CD inserted or the test will fail.
test tape Tests the SCSI tape drive by executing the drive selftest program.
test tape0
test tape1
(
tape
and
tape0
= SCSI target 4,
tape 1
= SCSI target 5).
test ttya
Outputs an alphanumeric test pattern on the system serial
test ttyb
ports (
ttya
= serial port A,
ttyb
= serial port B). You must attach a
terminal to the tested port to observe the output.
test
keyboard
Executes the keyboard selftest. The four LEDs on the keyboard should
flash on once, and this message is displayed:
Keyboard Present
.
test-all
The
test-all
command tests all devices in the system which have a selftest
program. Tests are executed in order using the device tree (viewed with the
show-devs
command) as reference. Disks, tapes, and CDROMs are not tested by
test-all
.
