About OpenBoot Diagnostics Tests

This section 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 page 181.

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

You can 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 be attached to the system and to an Ethernet tap or hub, or the external loopback test will fail if invoked. To quit OpenBoot Diagnostics, use the exit command, which returns you to the ok prompt.

You can 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 is displayed. 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
