If it's really a single disk LVM -- unmount it.. You need to do a pvscan, vgscan, and then vgchange -ay volume-group.. then mount /dev/volume-group/logical-volume. And if your other server already uses the same volume-group name - you will have to rename it before you can activate the new one. (if the lvm consists of more than the 100 disk - you need to link and activate those too..)
Sounds like you did a zipl -X at some point, which eliminates the startup menu.. Good luck!
