Many thanks, Alan. I did not know about md and thought that LVM was my only option to put together multiple volumes. Finally realized the software raid is available with loader and fdisk.

LVM and md (the multidisk layer) are two things. lvm deals with dynamic reassignment of space which is a nice thing to have. The md layer deals with raid 0 1 and 5. With md you can concatenate and stripe volumes. You can also do raid 1 and 5 although on S/390 I find it hard to see why you would do that at the Linux level Alan
