Hi everybody !
The problem was solved thanks to an ideea given to me by David Harrington
(Thanks David). I just modified the OBP variable boot-file from the from the
default empty field to "/platform/sun4u/kernel/unix" . Now works O.K. I
still think there is a problem in firmware, which was not solved by the
upgrade to the latest firmware level available. But since there is this
workaround available, I'm not too concerned about.

George; 

This is an old problem. 

Look in the archives Jan thru May, and I think you'll find the permanent way
around the problem. I had that problem when I first took over this job, and
there is a patch which fixes it. 

The short term (quick) fix is as you show: 

boot: cannot open kernel/unix 
Enter filename [kernel/unix]:           /platform/sun4u/kernel/unix [enter] 

Not a good solution with a critical machine!

Subject: Netra 1405 booting problem 


Hi everybody ! 
I have a Netra 1405 (same motherboard as Ultra80 and Sun E420R). I boot the 
sistem from the first internal disk (c0t0d0). 
However, every time I try to boot or reboot it, the machine stops and say 
"cannot open kernel/unix". I found a little trick, I press enter few times, 
then I press / and Enter once and then again I type kernel/unix and press 
Enter twice and the machine boots. 
I did not played with OBP variables and is the only one who do this. I was 
thinking is an outdated firmware and I upgraded OBP to a version from July 
2001 (before it was a firmware version from dec 1999). Nothing changed. The 
machine is new and always did this. 
I noticed is not a timing issue (for example I allowed plenty of time to 
internal disks to get started and still do not boot unless I do that trick 
typing / and then kernel/unix. 
It runs solaris 2.6 (latest Hw edition) and all relevant patches are 
installed. 
4x440MHz CPU's 
The internal disk is SCSI 36 GB (Sun Original) 
I'm out of ideeas, please help !! Sun enginner did not know what to do and 
probably will overkill by replacing all beast. 
Find below some boot messagess : 
Regards, 
George DONE
