+Subject: Fix grub2-mkconfig warning when disk is LVM PV
+References: bsc#1071239
+
+When a disk device was found in grub_util_biosdisk_get_grub_dev, its grub
+hostdisk device name just returned. Since the disk could also be used as PV
+disk, use grub_util_get_ldm to kick scanning of on disk metadata and adding it
+to VG array.
