Multiple LDom vdisks With the Same Backend

This is handy if you've got a file system (multi-writer) that supports concurrent writes from multiple hosts. Keep in mind, though, that while you can have 1:many relationship between backends and virtual disks (vdisk), the virtual disk server device (vdsdev) to vdisk relationship is still 1:1."
