How far do you get?  Do you see the Linux kernel running before it 
reboots?  What's the last message on the screen before the reboot?  You 
are booting the SAN with 'sanboot' or a DHCP root-path option, right?  
If so, which boot-loader is installed on the SAN?  Have you reviewed the 
following?:

And what about the following?:

http://www.etherboot.org/wiki/sanboot/winxp
http://www.etherboot.org/wiki/sanboot/winvista
http://www.etherboot.org/wiki/sanboot/win7

Can you connect to your SAN from any OS running on any box?  Checking 
this would rule out firewall or routing issues.  Does the 
to-be-SAN-booted OS tear down networking or bring up a firewall at any 
stage?  If so, this could cause problems.
