I have two DL380 server with esxi 5.5 running on the top of both servers. I have connected these servers via cross cables with primary and secondary nic cards. I have made a vswitch and adaptor to connect to VM hosted on the respective servers. when i reboot the machine i can see that i will not be able to ping each other , in order to ping i need to disconnect and connect the adaptor towards the VM. my nic teaming is in active standby . please suggest a way to avoid this issue
