R310/R410 dual PSU but single PDU

I have a selection of R310 and R410 which were purchased with dual PSU.

They are racked with just one of the PSU connect to the PDU, the other PSU has no cable and is basically cold-spare.

Naturally this causes a critical alert because full redundancy has not been reached.

I can't seem to find a way to dis-assert this critical status and stop the amber blinking/flashing that it causes, I've explored omreport and omconfig chassis pwrmonitoring/pwrmanagement without joy and "omconfig chassis pwrsupplies" doesn't exist...

How can I change the criticality of the alert, disable the probing of the alert or otherwise stop the false positive? (we don't want to/can't remove the spare PSU).

Thanks!

Hello Carl

I haven't tested this method myself, so I'm not 100% sure it will work. Here is the CLI guide for the DRAC:

http://support.dell.com/support/edocs/software/dtk/2.0/CLI/pdf/DTK20CLI.pdf

Almost all error lights and errors reported on our servers are initiated by the system event log/hardware log within the BMC/ESM/iDRAC. Disabling the error reporting within the iDRAC should stop the lights and any OpenManage errors you are receiving. Page 13 of the CLI guide discusses how to manipulate the SYSCFG.ini file. I do not believe the option to disable power monitoring is available within the GUI of the iDRAC(CTL E), but you can check.

To edit the .ini file you will need to have OpenManage Server Administrator installed. OMSA will give you the ability to run racadm commands. You can then use the syscfg -o command to retrieve the .ini file. After you edit the file you can then use the syscfg -i command to put the edited file back. The command syntax is discussed in the above guide. These are the lines I would look at editing to get the desired result:

pefcfgparams
filter=powerwarn
filteralert=enable
filteraction=none
pefcfgparams
filter=powerfail
filteralert=enable
filteraction=none
pefcfgparams
filter=hardwarelogfail
filteralert=enable

Changing those to disable would probably stop the errors. I would try powerfail first as that is the most likely one. Powerwarn will probably stop threshold or low voltage errors, and hardwarelogfail may stop all failure errors.

Thanks

simple methodology might work here like the 9th gen servers. Shut down the server, remove from power. Completely remove power supply number 2 from the server. Reboot, clear the event logs with open manage ect. and this should de-assert the error
