Check minor numbers for /dev/*/group
files.

# ll /dev/*/group

The minor number for volume group version 1.0
is ALWAYS 64.

The minor number for volume group version 2.x
is ALWAYS 128

#lvmadm -t

would tell you version.

While creating vg you can specify

vgcreate -V 2.0 -s X /dev/vgXX /dev/disk/diskXX

you don't need to check the lvm version in 11iv2 - it only has lvm v1.0
