Hi Joerg

Thanks for the inputs you gave me. However, I still have some questions/favors to ask of you...

1> What are the file systems from the root disk that I need to back up using the ufsdump command?
2> I also tried to create a back up using "mirror", however, after doing the mirror process, I got this message:
/usr/platform//lib/fs/ufs/bootblk : file not found
and the when I try to boot form the new disk, it won't boot...

I'm very grateful for the inputs you gave me and I'm exploring these things and I'm trying my best to learn/catch-up. So please bear with me if I still have confusions. Thanks and God Bless!!!

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 See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ od(1), uname(1), boot(1M), init(1M), kadb(1M), kernel(1M), monitor(1M), reboot(1M), rpc.bootparamd(1M), init.d(4), attributes(5) 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. 11 Apr 2005 installboot(1M)
