Today, host machine was disconnected from vCenter Server. I tried to re-connect the host but it was prompted the Error message, some like this that “host is not available on network” but the same time host IP was also pinging. I tried to connect this host individually vSphere client but still unable to connect the server. Secondly, at the same time, hosted VMs were pinging.
I tried to restart the management agent services of effected host machine through its console but It was show “Done” status against the management service down but its services did not up till 15 minutes.
I have tried to shut down the hosted VMs using "Shutdown Guest" option but VMs were goes to stuck state. I have no another option at that time to hard reboot the host. After rebooting the host machine, issue has been resolved now.
Kindly help me that why this issue was occurred. Actually, I have faced this issue three times with different hosts in a cluster.
Note:-This issue was raised mostly, when we perform more than one VM backup jobs through Veeam Backup and Replication v6.5.
