Creates a fire drill disk group on the secondary site with a snapshot of the application data to use for testing purposes. Offline Joins the fire drill disk group to the application service group disk group. Snaps back the snapshot mirrors to reattach to the original volumes. State definitions ONLINE OFFLINE UNKNOWN FAULTED Indicates that a snapshot is created and is available for fire drill. Indicates that a snapshot is not available for fire drill. The attributes of the VVRSnap resource are invalid. The VVRSnap resource goes offline unexpectedly outside of VCS control.
