OBDiag reports test results via the LEDs located on the system front panel. See “Error
Indications” on page 257 for more information about LEDs and error messages.
OBDiag displays detailed diagnostic and error messages on a local console or
terminal, if one is attached to system. Alternatively, you can display OBDiag output
remotely on a Remote System Control (RSC) console. For more information about
RSC, see “About Remote System Control (RSC)” on page 256.
OBDiag tests run automatically under certain conditions. You can also run OBDiag
interactively from the system ok prompt. For information about running OBDiag, see
“How to Use OpenBoot Diagnostics (OBDiag)” on page 248.
When you run OBDiag interactively from the ok prompt, you invoke the OBDiag
menu, which lets you select which tests you want to perform. For information about
the OBDiag menu, see “OBDiag Menu” on page 240.
The system also provides configuration variables that you can set to affect the
operation of the OBDiag tests. For information about the configuration variables, see
“OBDiag Configuration Variables” on page 242.
OBDiag Menu
The OBDiag menu is created dynamically whenever you invoke OBDiag in
interactive mode. OBDiag determines whether any optional devices are installed in
the system. If the device has an on-board self-test, OBDiag incorporates the test name
into the list of menu entries. It sorts the menu entries in alphabetical order and
numbers them accordingly. Therefore, the menu entries may vary from system to
system, depending on the system configuration.
The OBDiag menu always displays the core tests that exercise parts of the basic
system. These tests include
envctrltwo
,
ebus
,
ecpp
,
eeprom
,
fdthree
,
network
,
scsi@3
,
scsi@3,1
,
se
,
su
, and
rsc
. For information about each test, see “OBDiag
Test Descriptions” on page 244. For a description of the interactive commands for
running OBDiag, see “OBDiag Commands” on page 241.
Once you invoke OBDiag as described in “How to Use OpenBoot Diagnostics
(OBDiag)” on page 248, the OBDiag menu is displayed.
