Q: Are v2 7-Mode and v2 C-Mode licenses the same?
A: “In Data ONTAP 8.2, the only new license key required to build a cluster is a Cluster Base Key... For licensable ONTAP features, the same license keys used for 7-Mode are also used for clustered ONTAP 8.2.”*
*Slightly old information.

Also check the follow for snaplock options:

New @ thePub:
