This weekend we are planning on upgrading our IOS on our Cisco switch. This switch has our three ESX servers and the iSCSI SAN that the ESX server use connected to it.
In the past when we have found it necceary to reboot the switch all running VM's get shutdown, and then rebooted by the ESX hosts. I am trying to avoid this as it is not a graceful shutdown event.
Is there a configuration change that I can make in VirtualCenter that would prevent this from occuring? Or any other ideas as to why this would happen in it's not VirtualCenter related?
