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.
