Bootloader problem on IBM Power7 LPAR

Hello,
i have installed openSuSE 13.1 on a IBM Power7 LPAR.
The Problem is that the bootloader can not installed.

I installed the openSuSE on LVM (with multipath).

Yaboot (ybin) ist not available.
Is it possible to get it work with grub2 ?
Or is there another bootloader to boot ?

# grub2-install 
Path `/boot/grub2' is not readable by GRUB on boot. Installation is impossible. Aborting.

# grub2-mkconfig -o /boot/grub2/grub.cfg


#vgdisplay
