snapshot for multi-luns and multi-vols on linux

[ Edited ]

I have two vols and each vol has four luns.

I want to take the snapshot copy and access to it to get the data.

My environment is SAN (iscsi)  and eight luns to be present an mount pouint on linux (LVM ).

How can I do the snapshot copy and access to it?

I have host utility and SDU installed on Linux server. 

What is correct command I need to use?

 

# snapdrive snap create -vg vg_dr2prod1_test01 -fstype ext4 -snapname snaptest01
