Refreshing an instant snapshot replaces it with another point-in-time copy of a parent volume. To refresh one or more snapshots and make them immediately available for use, use the following command:

# vxsnap [-g diskgroup] refresh snapvolume|snapvolume_set \
  [source=volume|volume_set] [snapvol2 [source=vol2]...] \
  

If the source volume is not specified, the immediate parent of the snapshot is used.
