Hi, we experienced the following issue while upgrading 56128P:
upgrade was done on 18.08.2020 16:00 to 17:10VPC Primary (S32)
VPC Secondary (S33)
7.2.1.N1.1.
first we upgraded to intermediate 7.3.2.N1.1 - was OK
Update of VPC Primary (S32) was ok. VPC Secondary (S33) took Primary Role
and VPC Primary (S32) was booted and load the IOS.
then tried to Update to Software Version 7.3.6.N1.1. following Problems:
when Reload and Update of S33 - S32 didn't boot and did not came up as Primary VPC ?
we unplugged the PSU cables to resolve the issue
we see LOG UDLD received EMPTY ECHO Links Eth1/48, 1/49, 1/50 to S33
then S32 sh its Links to S33
1.) Why S33 did not booted correctly ?
2.) Why S32 did not became primary when S33 was rebooted ?
