I have a customer with a bunch of N4001i blade switches. They are all running either 4.1(2)E1(1h) or (1g). They upgraded to DCNM 6.1.1a. Within a few minutes all of the N4Ks crashed.
This is what was gleaned from a sh ver:
Reason: Reset triggered due to HA policy of Reset
System version: 4.1(2)E1(1g)
Service: statsclient hap reset
The statsclient appears to be the problem. Has anyone else seen this?
