It may not be that simple.

First, if you have a modern init (like systemd), the correct set of
dependencies there can help solve the ordering problem. It is not the
ordering that is the problem in most cases, but about how devices are
discovered. For example, if there are devices that are discovered by IB
after the iSCSI daemon start, in traditional method, they'd be left
over. Modern inits like systemd solve that problem.

As for root installed on a LUN, there's a lot of manual work in initrd,
that you'll have to add for opensm.
