I have 20 standalone ESXi 5 Servers in the vmware farm . For some reason we did not put them in cluster & SAN is not attached. all 20 esxi 5 servers have only their local storage . I am facing many issue with them .. such as
1. network connectivity lost
2. host disconnected
3. host unresponsive
4. Host not responding
when these alerts triggered then ESXi server becomes Gray and unresponsive . we are not able to connect the host for a while .... but after sometime.. ESXi server becomes green again and start working like nothing happened .
Could you please help me to understand the reason of that.
