File donot-support-unpartitioned-DASD-devices-with-CDL-formatted.patch of Package lvm2
pvcreate: don't support unpartitioned DASD devices with CDL formatted The former patch(dab3ebce4c7) is a little bit strict. For example, it is OK to create PV on unpartitioned DASD devices with LDL formatted. So after lvm version containing the patch, LVs created on those devices could not be found.
