Solution:
		   setenv auto-boot? = false
                   reset-all (hit stop-A right away)
                   probe-scsi
                   setenv auto-boot? = true
                   reset-all
I am attaching the -email from  Mark de Roo, I have not try it.

 > SYNOPSIS: Probe-scsi hangs on Ultras
 >
 > DETAIL DESCRIPTION:
 >> Probe-scsi hangs on ultras if you do a probe-scsi
 > after a halt or stop-A.
 >
 > SOLUTION SUMMARY:
 >
 > If you look at OBP command reference manual, the probe-scsi
 > done any other way produces unpredictable results,
 > that is, OBP will not know the state of system when it was halted.
 >
 > OBP cannot control what state the system ends
 > up in when it is halted; therefore, it doesn't know what part needs to be
 > re-initialized back to a known state.  The part(s) that needs to be
 > re-initialized might depend on the drive, or when the Stop-A was done, or the > version of the booter, or the OS that was running, etc.
 >
 > So the correct way of doing a probe-scsi is:
 >
 > Stop-A to get to ok prompt
 > ok setenv auto-boot? false
 > ok reset-all
 > ok probe-scsi   \ check your output
 > ok setenv auto-boot? true  \ reset auto-boot? and boot
 > ok reset-all
