os_winVCS service group with resource type HTC

You can configure a resource of type HTC in the main.cf file as:

HTC SQLDG (
    GroupName = SQLDG
    Instance = 1
    BaseDir = C:\\HORCM\\etc.
    )

Sample main.cf configuration for CVM with the HTC resource:

group HTC (
        SystemList = { fred = 0, barney = 1 }
        Parallel = 2
        ClusterList = { clus1 = 0, clus2 = 1 }
        Authority = 1
        AutoStartList = { fred, barney }
        )

                )
 
        CVMVolDg htc_dg (
                CVMVolume = { htcvol }
                CVMActivation = sw
                CVMDeportOnOffline = 1
                CVMDiskGroup = TCdg
            ClearClone = 1
                )
 
        HTC rep_htc (
