Diagnostics

Offline Diagnostics
Offline diagnostics run a sequence of tests on the system hardware under a standalone
diagnostic environment; the operating system cannot be running while the offline
diagnostics test the system
The offline diagnostics include a “launcher” that automatically runs a sequence of tests.
In most cases, you should run the offline diagnostics automatically with the launcher.
Use the following procedure to run the launcher:
1. Power on the system.
2. Wait until the System Maintenance menu appears.
Note: If the Autoload PROM variable is set to
Yes
, you must click on the Stop for
Maintenance button to access the System Maintenance menu.
3. Select the Run Diagnostics option.
Note: You can also start the launcher by entering the following command at the
command monitor (PROM) prompt (>>)
:
boot -f dksc (0,1,0) /stand/smdk/smdk --a
The launcher automatically runs the offline diagnostics on system components in the
following order:
• CPU
Note: The CPU test supports single-CPU systems; if a system has more than one
CPU, the CPU test does not run.
• Secondary cache
• Memory DIMMs
• I/O components: IO9 card and audio and I/O daughtercard (including the SCSI
controller, serial ports, Ethernet port, mouse port, keyboard port, and RTO/RTI
connectors)
