    My .02. The system that you are running is not a correct HP-UX install.
    HP-UX 10.20 boot disks are supposed to be SCSI ID 6.
    c(ontroller)0t(arget)6d(isk)0. You are booting off of target 0 ( the
    lowest priority on the SCSI bus ) the controller is id 7, the highest,
    the boot disk is supposed to be next (6). I do not know the exact code,
    but I never tried to run a system disk off of anything besides ID 6, it
    didn't work right, at least with 10.x
