Sorry for the dumb question but I've been through the docs and something is missing in my mind!

I have a data volume (dvol say) on a pool (dpool say) and I want to snapshot the volume in an NCF script so I can backup the volume snap shot. I can see how to snapshot the pool but I can't figure out how to see the snapshot of the volume!

The commands:
mm snap create snap_pool dpool dpool_snap
mm snap activate dpool_snap

create and activate a snapshot of the pool in which the volume I'm interested is in. However I can't see the volume or what to do to make it visible!

Advice appreciated!
