For hp-ux, you would have
pvcreate to create the physical volume
vgcreate to create the volume group
lvcreate to create the logical volume (or your mount point)
I seem to recall AIX as
mkdev
mkvg
mklv
So, take a look at mklv command.
The following link has a good cross-reference, so if you know a command for one unix flavor, it would point you to the associated command for a different unix flavor (or system type).
