Im trying to do an unattendet autoyast install on SLES 11 SP3 with a harddisk layout that looks as follows:

/dev/sda1 /boot ext3
/dev/sdb complete disk without making a partition /dev/sdb1 in volume group vg0
/dev/sdc complete disk without making a partition /dev/sdb1 in volume group vg1

/dev/vg0/lv_root /root xfs
/dev/vg0/lvxxxxx ... ...

/dev/vg1/lv_userdata /userdata xfs

Unfortunately the installation stops with the error: "Bei der folgenden Aktion ist ein Fehler aufgetreten: Volumegroup vg0 (0 B) wird aus erstellt.
Systemfehlercode -4004"
"Volumegroup vg0 (0 B) will be created from . Systemerror -4004"

Is it possible to do this setup with autoyast. I can make the setup interactive with these settings. The server works fine.
Cloning this fresh server and deploying the created autoinst.xml results in the above error.
