My Mac Pro ("Cyrus") has two 1 TB hard disks. When I reboot, only the first of those disks (also named "Cyrus"), the one with the system and home directories, mounts on the desktop. The second disk ("Virtual", need a better name, any ideas?) does not appear in /Volumes and doesn't work until I mount it manually in Disk Utility. This behaviour is seen consistently, i.e. after every reboot. Any ideas? How can I convince Cyrus to mount both disks?
