Reconnection extends the snapshot model by providing the ability to refresh and reuse a snapshot mirror, rather than discarding it. FR is automatically enabled when you take a snapshot of a volume. FR retains the association between the snapshot mirror and the volume when the snapshot mirror is detached from the volume.

FR reattaches and resynchronizes the snapshot mirror with the volume when the Snap Back command is issued, either through the vxassist command line command or the GUI.
