Plexes on windows

Hi all,
This is in reference to the doc which explains about the tool dmdiag
from microsoft. The link for that is
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q295406&. In this
doc a sample output is given. In that information about plexes and subdisks
is printed by this tool. But how those objects can be created is not
mentioned. Can they be created with out installing full fledged version of
veritas ? do anyone know of any light weight package from veritas (instead
of full fledged 3.2 volume manager) ?

Thanks in advance,
Nagesh Bhattu
