Test Description and Requirements
test disk Tests internal or external SCSI disks that have a self-diagnostic program
contained in the drive controller. The drive must be spinning before this
test disk0
test is executed or the test will fail. Enter a boot <disk alias> command to
test disk1 cause the drive to spin up. (disk0 = SCSI target 0, disk1 = SCSI target
1, disk2 = SCSI target 2, disk and disk3 = SCSI target 3.)
test disk2
test disk
test cdrom Performs a diagnostic self-test on the CD-ROM drive. The CD-ROM 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 self-test program. (tape
and tape0 = SCSI target 4, tape1 = SCSI target 5.)
test tape0
test tape1
test ttya Test outputs an alphanumeric test pattern on the system serial ports.
(ttya = serial port A, ttyb = serial port B.) You must attach a terminal
test ttyb
to the tested port to observe the output.

Sundiag System Exerciser

Use the Sundiag System Exerciser to determine real-time use of system resources and
peripheral equipment such as Desktop Storage Modules and External Storage
Modules. The Sundiag System Exerciser verifies that the system is functioning
properly. For information about how to use the Sundiag System Exerciser, see the
Sundiag User's Guide.
If Sundiag passes, the system is operating properly. If Sundiag fails, the error
messages should indicate the part of the system that has failed. If the error messages
are not descriptive enough, you may need to run POST or the SunDiagnostic
Executive.
Note - The Sundiag System Exerciser is not applicable to the SPARCclassic X
terminal.
