hi ;
group number is a hexadecimal number. 0x120000 (12) means 1*16+2=18,
but
kctune | grep maxvg
probabbly returns less than 18. so

1. change maxvg kernel parameter or
2. use less than 12 ( if possible )

I believe maxvgs requires a reboot to set it higher..default is 16 if I remember correctly.

So try to find VG value 16 or below...
