Check your /etc/zipl.conf to make sure the [ipl] parameters="dasd= ..." has the addresses of the volumes where your lvm's are defined (this ensure the volumes are mounted/on-line). During IPL, the volumes defined will be searched and if the LVM's are there and according to fstab, they will be made available. Other ideas, check your /proc/dasd/devices to make sure the volumes where your LVM's reside are there. Then, run a pvdisplay, vgdisplay and lvdisplay to figure out what could be missing. To activitate all volume groups run "vgchange -a y".
