This could start a holy war, but this is configuration which is recommended by Dell and, furthermore , not all storages have bonding capabilities, but, usually, they do have multiple ethernet interfaces. > Secondly, you can always define two iscsi resources that Pacemaker > manages via ocf:heartbeat:iscsi.

You have to colocate both resources and you can't use inf: in colocation because it would break redundancy (all or nothing) I guess lsb:iscsi RA is the only option.
