Adding a snapshot to a cascaded snapshot hierarchy

To create a snapshot and push it onto a snapshot hierarchy between the original volume and an existing snapshot volume, specify the name of the existing snapshot volume as the value of the infrontof attribute to the vxsnap make command. The following example shows how to place the space-optimized snapshot, thurs_bu, of the volume, dbvol, in front of the earlier snapshot, wed_bu:

# vxsnap -g dbdg make source=dbvol/newvol=thurs_bu/\


Similarly, the next snapshot that is taken, fri_bu, is placed in front of thurs_bu:

# vxsnap -g dbdg make source=dbvol/newvol=fri_bu/\
