OpenBoot diagnostic tests

OpenBoot Diagnostics (OBDiag) is a menu-driven diagnostic tool that diagnoses system hardware.

OBDiag performs root-cause failure analysis on the referenced devices by testing internal registers, confirming subsystem integrity, and verifying device functionality.

To use the OpenBoot diagnostic tests:

1.From the root login, turn off CMS.

2.Enter:

/usr/sbin/shutdown -y -i0 -g0

The system shuts down and the ok prompt is displayed.

3.Set the key switch to the diagnostics position.

4.At the ok prompt, enter the following commands: setenv auto-boot? false

reset-all

The system resets.

5.Enter: obdiag

This loads the test program and the test menu is displayed.

6.Do one of the following:

●On the V880, enter:

obtest <command number>

●On the V890, enter:

test <command number>

See Test descriptions on page 173 for a description of each command.

7.When finished with testing, set the key switch to the normal position.

8.Enter the following commands: setenv auto-boot? true reset-all

The system resets.
