Auto boot problem on Sun T2000
Hi All

I have a problem on T2000 server.

Code:
bash-3.00# uname -a
SunOS 5.10 aaa Generic_120011-14 sun4v sparc SUNW,Netra-T2000

After the initial solaris installation server failed to boot:

Code:
Rebooting with command: boot
Boot device: disk:b  File and args: 
The file just loaded does not appear to be executable.
{0} ok

So I ve decided to go with:

Code:
{0} ok boot disk

It was fine with booting like this! I was a little bit short on time So I couldn't fix it permanently and had to go with the workaround.

Later on when I checked the installation logs:

Code:
bash-3.00#
bash-3.00# tail -10 /var/sadm/system/logs/install_log

Customizing system devices
        - Physical devices (/devices)
        - Logical devices (/dev)

Installing boot information
        - Installing boot blocks (c0t1d0s0)
        - Installing boot blocks (/dev/rdsk/c0t1d0s0)
        - Updating system firmware for automatic rebooting
WARNING: Could not update system for automatic rebooting
bash-3.00#
bash-3.00#
What I understand is, I need to change the boot device or auto-boot.
System is running on a live environment now so I have to fix this without interrupting the server.

So with current conditions server will fail to boot If anything goes wrong and If server needs to restart.
My question is, what should I do to prevent this? and what is the safest way to do it without restarting server?

Any help/ideas will be great!

Regards
Oguz

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
