Restarting ESXi services causes a False HA Alert on Select VMs

From time to time we restart the ESXi servers on all ESXi6 host using services.sh restart. What I have noticed is the one two separate occations we received an alert that two VM which are cluster that HA failed to restart them yet when you log onto the guest. The VM's new restarted nor did Windows Failover manager indicate the application failed over. I know when I host disconnects it kicks in the host isolation responce. My question is why only one VM on an affected host that was clusted?

We run the services.sh restart command about once a correct to make sure the ESXi sevices on all hosts are refreshed and not having issues. Have seen odd issues in the past where an ESXi services were never restart for over a year

Hello,

I have not seen an ESXi where the management agents do not restart for a year.

Similarly, remember that when the management agents are restarted the vm of that host are not affected.

If you have a high availability cluster, you will always receive alerts about certain vm, depending on the event that happened.

I have seen issues when zoning a lun to the cluster leave, the cluster will use one host as the refernce host and if it is having issues, Other host will hosts will not see the new lun until the services are restarted. I had a case opened will support a while back and this was the recommendation

Hello,

I recommend you monitor the behavior of the Cluster and the Hosts for a few days and tell us the results.

the cluster looked fine and think this was a false alarm
