Thanks guys! These disks are ECKD 3390-3 dasd on DS8300.
Firstly I defined MDISK to that linux guest. Secondly using CPFMTXA utility to format thess dasds at range between cylinder 0 to END. Thirdly boot that linux guest, I didn't use fdisk and dasdfmt, but use YAST -> Hardware -> DASD -> Select target disks -> Perform Action -> Activate and Format. Lastly adding new volume group. Based on your explanation, I think the high possibility of my problem is that I didn't create partition for every disk before defining new volume group. My YAST steps didn't execute "pvcreate" operation. So when I added them to volume group, they were still /dev/dasde rather than /dev/dasde1.
