Below is my network Scenario,
2 Windows 2012 Hyper vhost (HP server) configured cluster manager.
HP SAN configured as data server.
4 virtual machines including Domain controller and DNS server. ( DC 1 AND DC 2)
Yesterday Upgraded Avast Antivirus on both the host. After some time none of the users were able to browse the internet or log on to their computer. Up on checking I found that all the VM are in failed state. As the DNS server is one of the failed VM the internet is also down. I have tried restarting HP server and SAN but none of the VM is listed in the hyper manager. In cluster manager I can see both the nodes online. I am able to ping from host 1 to host 2. Not sure what to do now? Please help
