Hello all,
 
on my web interface ONCommand System Management, i can see for all volumes, the snapshot copies related with size, date, etc.
 
I need to export this data. 
 
I have tried with CLI, "vol" command or "snap" command but i cant see the size of snapshots
 
My bay is n3400 and version command return : Data ONTAP Release 8.1.4P9 7-Mode
 
Someone can help me ?
 
Thank you
