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.
Yeah , ESXi Servers shows disconnection after some disk latency messages .. snapshots are given below :
Disk latency messages :
Host Disconnection :
ESXi servers backs up by itself after a while without doing anything
This will be helpful based on above data
What switches do you have and how are they configured?
What vSwitch configuration do you have?
I keep wondering if something like port security on the switch, or a duplex mismatch, is causing a physical drop.
i got /var/run/vmware/tickets/vmtck-52 .XXXXXX Could not be created by the application " hosted-worker" i have been getting this error after configuring SNMP traps on esx for netcool ( monitoring tools) .. i think it creates a problem too for non-responding esx issues
