I find that fdasd /dev/dasd_ shows "Linux Native" for a dasdfmt disks 
and it shows "Linux LVM" LVM after you do a pvcreate command to the disk.



Using p to look at the partitions and q to not change them ... 

Command action
   m   print this menu
   p   print the partition table
   n   add a new partition
   d   delete a partition
   v   change volume serial
   t   change partition type
   r   re-create VTOC and delete all partitions
   u   re-create VTOC re-using existing partition sizes
   s   show mapping (partition number - data set name)
   q   quit without saving changes
   w   write table to disk and exit

This is unfortunately (almost unbelievably) true - with the notable exception
of swap. Regardless of the partition type of a swap extent, pvcreate
recognises the swap header and will query you before trashing it.
Any other partition type - including those with valid filesystems and data -
will be fair game.
