I recently installed VCenter server to manage my ESXi 3.5u2 environment. After enabling HA i realized that i had not configured the userworld swap locations for each of the host. HA did not error out when i enabled it and vCenter server reports HA as enabled. My question is: Are the scratch config files no longer required for HA to function with the new vCenter server?
I am unaware of any configuration that needs to be made with regards to a "scratch config". HA is dependent on name resolution, and if HA configured correctly in your cluster, then more than likely you are ok.
When i was using the old version (virtual infrastructure manager) i had to configure the user world swap and scratch config for HA to configure properly. Otherwise i would get an error when i enabled HA on the cluster.
