Power supply problem

We have total 3 power supplies on HP 9000 L2000 model.
It is showing 2 power supplies failed when we checked on stm/xstm. But when Engineer checked physically, he is saying all are fine and he can see the power lights on.
Even in syslog.log it is showing error /opt/resmon/bin/resdata -R 177668106 -r /system/events/core_hw/core_hw -n 177668099 -a. We work from offshore.
can anyone help me in this?

Re: Power supply problem

hi,

login to the gsp and check the status of the power supplies there first

once logged onto the gsp issue the ps command

GSP>ps

this should show you the current status of the power on the system.

also check the event log

/var/opt/resmon/log/event.log

it could be that the power just got interupted for a short period? what is the time stamp on the errors?

Re: Power supply problem

I have seen a failed power supply with the green light on in the past.

You should check from GSP:

GSP> ps


PS

Power Monitor Status:
Firmware Revision : A
System Power state: On Power Switch : On
Temperature : Normal Selected fan state: Normal

Power supplies | Fan
# State Type | States
-----------------------------------------------------------
0 Normal Type 0 | Normal
1 Normal Type 0 | Normal
2 Not Installed - | Normal

and from hp-ux:

# echo "sel dev 1;info;wait;il"|cstm

...

Cabinet 0

Cabinet 0 Hardware Inventory:
Component Present Failure State
--------- ------- ------- -------
Cabinet Fans (blowers) 8 0 unknown
Cabinet Power Supplies 3 0 unknown
I/O Power Supplies 0
BackPlane Power Supplies 0
...



What is this telling you:

/opt/resmon/bin/resdata -R 177668106 -r /system/events/core_hw/core_hw -n 177668099 -a

Timestamp?

Maybe the power source was off and is now on again.

Hope this helps!

Torsten.

Re: Power supply problem

Try checking under the GSP command PS. Also check that power cables are correctly installed. Something very common is that they release the PDU

Good Luck

Re: Power supply problem

hi,

server wont run if no gsp card installed.

I guess you just dont know how to use it, or it hasnt been set up for remote login?

your output shows a failed PSU though

Cabinet Power Supplies = 3 (1 Failure; Power Supply 2)
