Check your path.
[root at atlantis mpeters]# which pvcreate
/usr/bin/which: no pvcreate in
(/usr/kerberos/sbin:/home/mpeters/cxo_bin:/home/mpeters/cxo_bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/mpeters/bin)
[root at atlantis mpeters]# su -
[root at atlantis ~]# which pvcreate
/usr/sbin/pvcreate
[root at atlantis ~]#

If you became root with just an "su" then you do not have root's path.
You have to use

su -

to get roots path.
