Nexus 3000 C3064PQ crashes after upgrade

Hi all,

Please help me with an issue after upgrading my Nexus 3000 N3K-C3064PQ-10GX

I've already upgrades some of them and I found no issue. I am followed exactly the same steps on all switches. All are same model and hardware revision. However I am facing boot loop after upgrading two of them.

 

Original version running nxos.7.0.3.I7.9.bin

Target version: nxos.9.3.7.bin

 

I compact image on USB flash drive and then install compacted image to the switch. After reboot the switch falls into boot loop with following error

switch login: 2021 Oct  9 05:39:27 switch %$ VDC-1 %$ %USER-2-SYSTEM_MSG: - E - Failed Opening Device rc=-4 - neutron_usd
2021 Oct  9 05:39:42 switch %$ VDC-1 %$ %USER-2-SYSTEM_MSG:  retry failed. Exiting. retry_count =5 - neutron_usd

Please help to understand what is going on.

Try getting into loader, boot up previous image and see if the switch comes up.

If yes, then you are facing a bug. Check what is different between the failing switches and the working ones (hardware, config differences etc).

 

Stay safe.

It is working fine with older version. It is not config issue, we tried to reset config completely. I checked and find some hardware difference

This is older one is working fine with 9.3.7

Switch is booted up
  Switch type is : Nexus3000 C3064PQ Chassis
  Model number is N3K-C3064PQ-10GX
  H/W version is 1.3
  Part Number is 68-4363-03
  Part Revision is F0

 The new one does not want to run with 9.3.7

Switch type is : Nexus3000 C3064PQ Chassis
  Model number is N3K-C3064PQ-10GX
  H/W version is 1.6
  Part Number is 68-4363-03
  Part Revision is M0

I could not find anything related neither in release notes nor in bug search. Looks like a bug
