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.

NAME

       grub - GRand Unified Bootloader software on Solaris

       The  current  release  of the Solaris operating system is shipped with the GRUB (GRand Unified Bootloader) software.  GRUB is developed and
       supported by the Free Software Foundation.

       The overview for the GRUB Manual, accessible at www.gnu.org, describes GRUB:

	      Briefly, a boot loader is the first software program that runs when a computer starts. It is responsible for loading  and  transfer-
	      ring  control  to  an operating system kernel software (such as Linux or GNU Mach). The kernel, in turn, initializes the rest of the
	      operating system (for example, a GNU [Ed. note: or Solaris] system).

	      GNU GRUB is a very powerful boot loader that can load a wide variety of free, as well as proprietary, operating systems, by means of
	      chain-loading.  GRUB  is	designed  to  address  the complexity of booting a personal computer; both the program and this manual are
	      tightly bound to that computer platform, although porting to other platforms may be addressed in the  future.  [Ed.  note:  Sun  has
	      ported GRUB to the Solaris operating system.]

	      One of the important features in GRUB is flexibility; GRUB understands filesystems and kernel executable formats, so you can load an
	      arbitrary operating system the way you like, without recording the physical position of your kernel on the disk. Thus you  can  load
	      the kernel just by specifying its file name and the drive and partition where the kernel resides.

       Among  Solaris  machines, GRUB is supported on  platforms. The GRUB software that is shipped with Solaris adds two utilities not present in
       the open-source distribution:

       bootadm(1M)

	   Enables you to manage the boot archive and make changes to the GRUB menu.

       installgrub(1M)

	   Loads the boot program from disk.

       Both of these utilities are described in Solaris man pages.

       Beyond these two Solaris-specific utilities, the GRUB software is described in the GRUB manual, a PDF version of which  is  available  from
       the Sun web site.  Available in the same location is the grub(8) open-source man page.  This man page describes the GRUB shell.

       boot(1M), bootadm(1M), installgrub(1M)
