Recently we been upgrading our environment to 6.7 , at the same time we also patched/updated drivers and firmware to supported versions.
After this upgrade we have seen issues with VMs intermittent lose network connectivity after a vMotion.
The remedy is to manually migrate the VM to some other random host.
ESX 6.7 U1
HPE FlexFabric 20Gb 2-port 650FLB Adapter
HPE VC 4.62
We actually had the same problem a year ago and then we managed to solve this with using a specific combination of firmware/driver for the 650 adapter + Flex VC.
Combination we have to day where we do see the problem :
We have a case with both VMware and HPE , but it feels like they don't have a clue on how to solve this.
We have very standard hardware/setup so I think many people round the world must have the same problem as we do?
Maybe someone has a solution?
