Karl, Red Hat did not include LVM in their Linux/390 7.2 distribution because of concerns about the stability of the code. At this point in time, the only option you have for volume aggregation is software RAID0. Unfortunately, this doesn't offer the same dynamic addition/deletion capabilities of LVM, but it's really the only choice you have for Red Hat 7.2.

Hello list, I'm playing with LVM, and, well i'm stuck. I have tried any number of configurations; using fdasd to partition dasdc, using freshly dasdfmt'ed dasdc, and on all attempts pvcreate fails. I can partition this drive and mount it. Normal read/writes work, so i guess the VM end of things is OK. Has anyone done this? Does anyone know what i've done wrong? Does anyone know if this can be done?
