I'm not familiar with the Netra. But I found this on Sun's web site...
Quote:
The Netra[TM] X1 server comes preinstalled with Solaris[TM] 8 Update 2 (10/00), including LOM (Lights out Management)software and all the patches it needs to function correctly. Because the Netra X1 server does not contain a CD-ROM drive and the Solaris installation media is not bootable on this system, if you need to reinstall the Solaris 8 operating environment, you must do so from a network install server. Additionally, the Netra X1 Drivers must be downloaded from Sun and added to the installation image.
This means that if you can't get that thing to boot, you are going to need a network install server. And really, you are going to need a Sun/Solaris guru to go with it. I guess that I might call my local Sun office and ask them to handle this.
Before that, I would be sure that I really can't get into single user mode. Can you get an "ok" prompt? What are you doing to get into single user mode? "boot -s"? If that doesn't work you may need to use the above procedure to reinstall.
I found one Sun Doc that says "boot -s" from a cdrom is way out of a corrupt /etc/default/init so it may be impossible to get to single user mode with a corrupt /etc/inittab as well.
If you do get yourself out of this fix, please post back and tell us what it took. Good luck.
