The database cluster is a GCO cluster that uses the HTC agent, but the application cluster does not run the HTC agent. The application disks are replicated using the HTC resource on the database cluster. I saw the mention of vxdctlenable in the HTC agent guide, but I could not find any additional information on what it actually does, so we didn't enable it. Do you have any pointers to additional documentation about adding the vxdctlenable action to the SupportedActions attribute? Is there any risk to adding vxdctlenable to the SupportedActions attribute at the primary site?
