Hi All,
It is something annoying issue.
The host esxi 6 or esxi 5.5 get disconnects from vCenter and reconnecting host will not work.
1. I can ping the host
2. I can ping the VM's running on them.
3. I can do ssh/rdp on the VMs running on them.
4. I can login console.
5. I can start management agent from DCUI but it doesn't reconnect host back.
6. The console get freezed when I try to enable Shell or SSH from DCUI.
I have to do force reboot the host to get it back to vCenter and VM's running on them will get rebooted.
When I went to went I saw before host gets not responding stage , the following message in event.
Virtual machine creation may fail because agent is unable to retrieve VM creation options from the host (N5Vmomi5Fault17HostCommunication9ExceptionE(vmodl.fault.HostCommunication))
It is there for most the host and its going since many days.
VMware support could able to identify the root cause.
Does any one had similar issue and what they do to fix them.
