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.

Try the solution suggested, if it doesn't work. Call Support.

Hi, thanks for your reply. But I was checked on system environment sensors show, node A PSU1 FRU state was fault.

Have a look at this kB:
https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/Power_supply_cannot_detect_power_off_correctly

Have a look at this, though it doesn't say your specific Model:
https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/CHASSIS_FAN_FRU_FAILED%3A_Multiple_fans_have_failed_after_upgrading_SP_BMC

Parallelly, log a call with NetApp Support.

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

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

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?
