The solution (at least for us):

We never discovered precisely why the clients failed to boot, but reinstalling
from CD made the problem go away. The part of this procedure that is not well
documented is "How do I get a Sparc 10 running 4.1.3m to support 4.1.3c clients
as well as 4.1.3m clients?"

The answer is: After you install your new system from CD, leave the CD on line
and reboot using the newly-installed kernel. Go to /usr/etc/install and run
add_services. Choose the "Add New Release" option on the form. You'll be
presented with a seris of questions that will eventually allow you to install
support for other architectures.

For those who asked, the document we got from Sun (via FAX) is:

Infodoc ID: 1269
Synopsis: Diskless Boot Troubleshooting Guide

It contains some interesting info, but nothing that helped us get to a solution
to our particular problem.

Several respondents provided useful advice that might be interesting to others.
Details follow:


From: (Russ Poffenberger)

I assume you did "add_client" for the clients? Even if you moved the stuff over before, I suggest you re-run it. You may have to delete the clients first.


From: Dan Stromberg - OAC-DCS <>

Be sure you have the appropriate symlinks in /tftpboot. Be sure you have tftpd enabled in /etc/inetd.conf.

Try killing rarpd and rpc.bootparamd, and starting (probably in two different xterm windows) with the "-d" option.

If you have a solaris 2 box, use snoop to watch the packet activity. Snoop often tells you exactly what file was being hunted for, when there's a file that can't be found. There is a snoop available for solaris 1, though it's unsupported there.


From: (Adam Fox)

You didn't say anything about if tftpd was set up. I suggest you check the following:

1) That tftp is NOT commented out of the /etc/inetd.conf file of your boot server. You normally don't want tftpd, except when you are booting diskless.

2) That tftp is no commented out of your /etc/services file.

3) That you have a /tftpboot directory with entries for the Suns you are trying to boot. You'll need the IP address in hex and an <ip_address_in_hex>.`arch -k`. These should be symlinks to the proper boot block in the /tftpboot directory.

For example: If I'm booting a sun4c at, then I would need:

C01FC005 and C01FC005.SUN4C

as symlinks pointing to the boot block for sun4c.sunos.4.1.x

Use bc to find the hex values

quine: bc obase = 16 192 C0 < -- 192 = C0 31 < -- 31 = 1F 1F 192 C0 5 < -- 5 = 05 (use 2 digits each) 5

Use etherfind on a 3rd host to see if you are actually tftp'ing.

I had asimilar problem. While upgrading a sparcstation 1+ running 'sunupgrade -v' always produced 'Unable to ... tftpboot ...'. Don't remember exactly. The fact was that in /tftpboot (where our boot images for the clients laying) the symlinks where pointing to boot.sun4c.4.1.3 (something like that). But there was only a file called boot.sun4c.4.1.3_U1 ! All I did was copy the boot*U1 to boot*4.1.3! After that the clients booted as usual.
