iSCSI snapshot requires the Local Protection license when using the cli and/or GUI.  Snaps can be taken through unisphere/cli without the requirement of RM, but the snaps will not be applicaiton consistent.  Does this answer your question?
Hi,  I'm wondering if it is possible to create iscsi snapshot on a VNXe storage through cli and WITHOUT Local Protection license, I mean without Replication Manager.  Thanks for your support.   Mario
