The solution to this problem ended up being that I had to create a new lvmtab
file by running vgscan but however when you ran sam to view the devices you
did not see the volume groups but after a reboot everything looked ok. So it
must have been that the kernel had read in a previous version of the file and
was getting confused and the reboot put both versions in sync so to speak.
