Power state on Chassis # is redundancy-failed

Hi,

I know this error used to be common a while back, but I'm running 2.0(2q) with four apparently healthy PSUs per chassis in n+1 mode and consuming using less than 800 watts across four B200 M2 blades. Help?

Thanks,

Hamish

Power state on Chassis # is redundancy-failed

Can you paste the output of the following commands:

scope chassis x

show psu detail

show psu-control detail

show fault

Power state on Chassis # is redundancy-failed

Hi Hamish ,

If you access the UCSM, do you see any PSU with a N/A status?

Does UCSM report any alerts such as upper non recoverable, thermal alerts or power redundancy lost?

Do you see any amber light on the power supplies?

You can reseat the power supplies one by one in order to see if they come back online.

Sometimes the chassis can generate thermal alerts and it can be related to a fan or even the IOM.

Go ahead and check the status of the power supplies physically and on UCSM.

Also collect the information from the commands Robert suggested.

Re: Power state on Chassis # is redundancy-failed

Hello,

I'm having the same issue in 2.0(4d). I have a UCS-system with two 6120XP and a three 5108 chassis.

The system is configured for N+1 redundancy:

Re: Power state on Chassis # is redundancy-failed

Hi,

Not sure why this is the first reply I've recieved notification for.

I opened a case with Cisco on this and was advised to change the policy to Grid, then back to N+1. This cleared the error for me.

Hope this helps.

Re: Power state on Chassis # is redundancy-failed

The problem might be with the subordinate IOM.  The active one, which returned the outputs requested above looks good.

Please do the following from the UCSM CLI:

ssh to fabric Interconnect A

connect iom x (x = chassis # showing redundancy lost)

show platform software cmcctrl power redundancy

ssh to fabric interconnect B

connect iom x

show platform software cmcctrl power redundancy

Thanks,

Robert

Have you tried to change the power policy to non-redundant and then back to N+1?

This is not disruptive.

Hi,

Yes, we did it, but didn't work for us...

Re: Power state on Chassis # is redundancy-failed

Javier,

Please open a TAC case, and attach the chassis (one for each chassis) and UCSM tech support to the case.

Power state on Chassis # is redundancy-failed

Please open a TAC case as Kenny suggested, but also look in to the following known defect and applying the workaround if applicable:

CSCub53747

Beginner

Power state on Chassis # is redundancy-failed

Hi,

According the bug toolkit, the CSCub53747 should be fixed in 2.0(4a). We're now in 2.0(4d).

We've opened a TAC case. I'll put here the conclussions.

Thanks!

Javier

Power state on Chassis # is redundancy-failed

Hi Javier

Did the TAC provide you with a workable solution ? I seem to have the same issue as well on my end. However , in my case its a UCS 5108 with 4 Power Supplies connected and on N+1 option.

Beginner

Power state on Chassis # is redundancy-failed

Hi,

Not yet. We're working on that, but the TAC recommends to go to 2.0(5b). These bugs seems to be hitting us:

CSCue49366, CSCud48637/CSCue33889.

Javier

Power state on Chassis # is redundancy-failed

Hi Javier,

Have you already solved the issue ?

I'm having the same problem and I'm on

2.1(1e)

Bruno
