What are the scsi ids of your disks ?
Is /dev/sda the first disk in the chain ? If not maybe you have to boot
with "boot disk<n>" where <n> is scsi id.
I recall that Sun swapped id 0 and 3, so if, for example, /dev/sdb could be id
3 and /dev/sda id 1. And you could have your old rh-silo installed on
/dev/sdb called by default ;(
Hope this help.
