About OpenBoot Diagnostics Tests
Thissection describes the OpenBoot Diagnostics tests you can run and explains what
each test does. For instructions on running OpenBoot Diagnostics tests, see “How to
Isolate Failures Using OpenBoot Diagnostics” on page181.
When you use the obdiag command at the ok prompt, OpenBoot Diagnostics
displays a menu of available tests. The menu is dynamic, and test numbers are not
fixed. Following is an example of the menu.

The test Command
Youcan run a specific self-test at the obdiag> prompt by entering test n, where n
is the number of the test in the menu. (Enter help at the obdiag> prompt for
information about other OpenBoot Diagnostics commands.) An Ethernet cable must
beattached to the system and to an Ethernet tap or hub, or the external loopback test
will fail if invoked. Toquit OpenBoot Diagnostics, use the exit command, which
returns you to the ok prompt.
Youcan also run OpenBoot Diagnostics commands from the ok prompt for any
device by invoking its self-test method. If a device has no self-test method, the
message No selftest method for device name isdisplayed. To run the
self-test method for a device, type the OpenBoot PROM test command at the ok
prompt, followed by the device alias or device path name. For example:
ok test net
Testing network
ok
