We have vPC auto-recovery enabled on a pair of Nexus 7Ks. The two switches are in two different computer rooms.
The N7K is in Computer Room 1 (N7K1) was vPC primary and the N7K in Computer Room was vPC secondary (N7K2).
Over the weekend the power to Computer Room 1 was taken down for maintenance and then restored this morning.
As exepected the N7K2 has transitioned to the role of secondary, operational primary.
When N7K1 rebooted it has transitioned to vPC primary, operational secondary.
I have two questions:
1. In order to re-establish N7K1 as vPC primary does it need to be rebooted?
2. Is there are any real reasons to do this if the network is functioning as expected, for example any impact on spanning-tree or HSRP? There will be another power shutdown in a couple of weeks.
