Follow the cloning procedure; you'll find loads of references to it in the
archive. This will install any additional device files.

Don't bother. It's used to ensure that the placement of the rootvg in the
target system is the same as the source. But that really doesn't matter all
that much and unless you've got the same sized disks it can't do it anyway.

You don't; it's irrelevant.

Looks alright. Note that TSM doesn't care very much about how filesystems
are allocated; provided there's enough space it'll be happy.
One thing to consider is the network: your H50 will be configured
identically
to the H70 when you restore it. That means that it will have the same IP
addresses. For a real DR that doesn't matter, and is actually desirable.
For a test, you will need to take steps to ensure that it doesn't lead to a
duplicate address on your network. The simplest thing to do is unplug the
network cables until you've had a chance to reconfigure the network
interfaces.
Of course, if you're not on a shared network there won't be a problem.
