Our company has created a procedure for creating a backup root disk called BROOT. All new boxes are put into production with this functionality.
It was meant for an add'l recovery disk for VG00, but it can be used to copy from one disk to another, when you might ever upgrade a Disk to a larger one.
Here is the script. We have a script that creates this script, but this can be edited and reused. This should give you something to work with.
I didn't write this, but it is very good for this type of work

I have a SunOS 5.8 server. I suspect there may be errors with one of the physical disks (based on someone reporting hearing a "clicking sound" during the night shift, however I do not hear anything this morning).
Which log would show this?

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
