Hello,
We have a cluster of 4 ESXi 4.1 (U2) host.We witnessed a incident where all VM's were powered off and then were restarted by HA on two of the hosts at almost the same time,
However both the ESXi host were up during this time.
We did see some network related issues in the logs like
but since host isolation response is also set to leave VM powered so please can anyone help as to what could have caused the VM's to restart.
Thanks
We are using NAS based storage for the VM's and and are getting following error for vmnic's which are used for NAS storage:
Could be various things but most obvious:
Hosts were isolated, both storage network + management network. Because hosts were fully isolated it appears to the rest of the cluster that the host is dead. Reasons are:
1) no heartbeat coming in
2) not responding to a ping to the management interface
3) when trying to restart the VMs the VM files are not locked
So the remaining hosts in the cluster will be able to restart the VMs...
