We have been running a VMWare cluster using dual IBM servers connected to an IBM DAS. Whenever I connect to VCenter it shows all the VM's as orphaned and disconnects after about 40 seconds. When I log onto each esxi server both have the same error message (Cannot synchronize host. Cannot connect the specified. the host may not be available.) Please see the attached screenshot. Is there a way to fix this without shutting down VM's or the hosts, as I cannot migrate them?
