troubleshooting cause of amber light
hi all,

we've got an amber maintenance light on the front of our Netra-t4. I can't find out what's causing this issue. I've logged into the lom, and found the following. There's nothing in messages or prtdiag. Disks appear to be ok. Are there any other lom commands that can help?

Code:
lom>environment
LEDs:
1 Power            ON
2 Fault            ON
3 Supply A         OFF
4 Supply B         OFF
5 PSU ok           ON
6 PSU fail         OFF
 
Alarms:
1 -                OFF
2 -                OFF
3 -                ON
 
PSUs:
1 AC               OK
 
Fans:
1 PSU1             OK speed 75%
2 PSU2             OK speed 74%
3 CPU              OK speed 73%
 
Temperature sensors:
1 Ambient          OK 21degC 
2 CPU0 enclosure   OK 23degC 
3 CPU0 die         OK 52degC 
4 CPU1 enclosure   OK 23degC 
5 CPU1 die         OK 50degC 
 
Overheat sensors:
1 PSU              OK
 
Circuit breakers:
1 SCC              OK
2 PSU              OK

I'm assuming that it's alarm 3 causing the issue. Any idea what this indicates?

checkout these command
consolehistory

From the OS, what does prtdiag shows?
Any weird errors in the messages file?

nope, there's no errors in the messages or prtdiag -v. I checked out the lom manual, and alarms 1-3 are user definable.

Alarm2 is showing as alerting - would that cause the amber maintenance light? As far as I can tell, there is no way to check what causes alarms 1-3 to trigger.

i've run the 'check' command at the lom, which has reset the amber light. I'll see if it triggers once more.

many thanks.

Just to confirm, the amber light glowing is beside which icon?

the amber led is on above the spanner (maintenance) symbol. To the right of it is the green power led.

I'm fairly sure this was caused by alarm3 being set off. Although I don't know why this occured. Consolehistory doesn't give me much info. The Lom manual just states that alarms1-3 are user definable - no other info provided Smilie

Sometimes this kind of situation justs work if you can try the following:
1-Gracefully shutdown and poweroff the system
2-Pull out the 2 power cords at the rear.
3- wait for about 30secs or so.
4-plug in powercords and monitor the console messages (ILOM messages, for any errrors)
5-Power on the system and see if the LED goes off.. Smilie

Since Alarm 3 is user defined, why not look for the user definition of this alarm on your machine?
