Here Sgi Octane Diagnostic Troubleshooting cover octane, octane 2 related hardware and software issues.
There are several methods to find out Octane issues like hardware inventory, diagnostic testing, or command-line instructions.
Octane diagnostic tests and troubleshooting methods are very accurate.
Tests of Sgi Octane Diagnostic Troubleshooting
All the tests fall under power-on tests, hardware inventory, interactive diagnostic environment (IDE), and confidence tests.
Power-On Sequence
As soon as turn on the power front cover light bar shows red color. Till power-on self-test successfully finished remains red.
In the next step monitor shown starting up the system pop-up window. From here by pressing Esc or click on the stop for the maintenance button can enter in diagnostic menu.
Otherwise after five seconds next pop-up window The system is coming up will display and the operating system desktop will appear.
Power-On test Sgi Octane Diagnostic Troubleshooting
The Sgi Octane computer front panel LED bar provides rock-solid diagnostic information for troubleshooting.
When any test failure occurs during octane initialization, the LED’s status clearly indicates the issue.
Here, LEDs indications on test failure are described, as well as their possible sections diagnosis and troubleshooting.
Similarly, sgi o2 diagnostics troubleshooting will help to troubleshoot Sgi O2 / O2+ related problems.
Some of the options are common for sgi O2/O2+ and Octane therefore avoiding duplicate never mentioned here.
Advised also refer sgi o2 diagnostics troubleshooting for a complete understanding of Sgi Octane Diagnostic Troubleshooting.
Using CPOP Connector LEDs Diagnosis
CPOP is seven green LEDs in two-column. The first left column has four LEDs and the right second column have three.
Placed at the right bottom side behind the front cover and just right to the DB15 connector.
Although CPOP is not meant to Sgi Octane Diagnostic Troubleshooting purpose.
But gives XIO module connection status acknowledged by hardware.
Similarly, the rest of the led to display the ASIC Heart ok status indicator. Each LED gives the following information
1. Base IO Main System Module is seated/detected OK
2. A Quad Top left XIO quad module is seated/detected OK
3. C Quad Lower right XIO quad module is seated/detected OK
4. D Quad Lower left XIO quad module is seated/detected OK
5. PCI PCI chassis/ASIC seated/detected OK
6. B Quad Top right XIO quad module seated/detected OK
7. Heart Heart memory control ASIC on System Module status OK
Use Non-Maskable Interrupt (NMI)
When the system never responds and never shows any error message.
Then by pressing the NMI system can be shut down and all the activity stored in the file for further analysis.
Placed down to the reset button. Need pin or clip to press the button.
Octane Panic Massage
Panics are un-recoverable errors caused by octane computer hardware failures.
The symptom includes a Panic error message, the computer hangs, and the need to restart the power cycle.
After reseating hardware problems never resolve them need to replace the hardware.
hinv (Octane hardware inventory test )
Whenever octane boots, create a log file for detected hardware devices was found. It can be read from boot time created log file with the hinv command.
Also can verify the software can communicate with the hardware as expected.
If the octane has a bad memory module, then the system should have less memory than is installed.
But IRIX uses more of the virtual memory as a swap partition. The error log will show no entry about missing memory.
IRIX operating system will detect every hard disc drive connected to the SCSI controller.
Integrated Diagnostics Environment (IDE) Tests
The IDE tests, available for sgi octane diagnostic troubleshooting purposes are more comprehensive than the confidence tests.
They are stand-alone tests for sgi octane diagnostic troubleshooting purposes and must be run at the boot PROM level.
To invoke these tests for sgi octane diagnostic troubleshooting, shut down the system.
Startup the system, and when the System Start-up notification pops up, select STOP FOR MAINTENANCE.
From the System Maintenance menu, choose RUN DIAGNOSTIC. A single user shell will open, and the results of an hinv probe will be displayed.
The IDE tests will auto-configure and start execution immediately upon entering the diagnostic environment.
A default set of tests that tests the CPU, memory, and graphics boards automatically takes about 25 minutes to complete.
Pressing the Esc button will stop the test and the system will return to the maintenance/start-up menu.
Instead of the Esc button select Ctrl-c to return on command prompt and from here can run an individual test or test scripts.

Then for sgi octane diagnostic troubleshooting, the IDE tests can run from CD-ROM by inserting IRIX CD inside the CD-ROM drive and run the test from CD-ROM.
Confidence Tests for sgi octane diagnostic troubleshooting
Confidence Tests run for sgi octane diagnostic troubleshooting determining whether peripheral devices.
Such as the keyboard, monitor, mouse, and CD-ROM drive are functioning properly.
Tests can be run on IRIX desktop command prompt window for sgi octane diagnostic troubleshooting. To initiate tests type “confidence” at the command prompt.
A window will pop up containing an icon for each testable device present.
By clicking on icon invoke the diagnostic that will test that device.
Below the status window icon displays information such as which devices are present and which are not.
