Not really. The article is really about simple playing around with
combining block devices using the command "dmsetup".

I don't know Powerpath/DMP. In particular, I don't really know what
"multipath" means --- perhaps you can enlighten us! :-)

Note that "dmsetup" is a low-level utility. To do anything even
slightly complex with this it is best to use some tools which will
automate things and prevent lock-ups. Depending on your needs the
tools could be shell scripts, multipath-tools, lvm2 or evms.

Kapil.
