This suggests that the disk was a later addition to the system, and that
  there has not been a reconfiguration boot since its addition. From
OBP, you could have done a boot -r, or to constitute the device files
and links, you could have done drvconfig;disks. You could also touch a
file called /reconfigure and do a normal boot.
