disk0 is only an alias for a real device. Type 

  devalias

and look what disk0 really is. Maybe this is misconfigured. 

Next: Type

  probe-scsi

and look if your boot device is there and has the correct id. (must be the same
as the devalias output /pci/... at 3 (for example, then it's id 3 that must be
present in the probe-scsi output, 3 is common for sun4c/sun4m machines, sun4u
machines use id 0)

Last: Boot from CD and try to mount your boot device.

Which machine type/model is it?
