Open a case with the support center and start scheduling some downtime for a chassis swap, but I must stress this is very very uncommon.

 

The reboot and the upgrade should fix it.

Reboot the BMCs on both nodes in the chassis.

Then update them to BMC 11.6.

The sensor reading failures can indicate issues with IPMI communication or BMC unhealthiness.

Create a case with Tech Support, ideally.

Terry_Lui

Cool, Thanks andris. But is that any services impact druing BMC upgrade?

AlexDawson

BMC upgrades are generally non-disruptive - rebooting the BMC first will help ensure a smooth upgrade leading to non-disruptive activity. Command is "system service-processor reboot-sp -node nodename"

Terry_Lui

Thanks for your reply Alex, i will try it later. I was saw one of KB said that to upgrade shelf firmware will help for this case. If i upgrade for shelf firmware also, did any services impact? 

AlexDawson

Shelf firmware update is also generally non-disruptive, but it is important to perform the BMC reboot and BMC upgrade first.

Terry_Lui

That cool, thanks a again Alex. If after upgrade SP and shelf firmware the alert still exist, what should i do on next step?

I hope it can fix it this problom by upgrade, I try to contect with customer to upgrade those part first. BTW, thanks for your help again Alex.

Terry_Lui

Thanks again, I will take a look for those KB.
