Code:
if the 2nd drive is empty or reconfigurable --- 

1. partition the 2nd drive into the setup you want to be the final layout

2. newfs all the new data partitions on the 2nd drive

3. copy all the data over from the 1st drive to it's new home on the 2nd drive


if you plan on booting up the 2nd drive as another boot device ---

1. install boot block on / partition of 2nd drive

2. edit /etc/vfstab on 2nd drive to reflect correct disk devices for mounting


if you plan on physically swapping drives ---

1. install boot block on / partition of 2nd drive

2. power off system, swap drives in slot0 and slot1, and boot

... for your first time doing this, i suggest you try to boot the 2nd drive as an alternate boot device as failure of that drive to boot means you missed a step and swapping drives will not make it work any better ...

anyways, i've found through the years that having the / filesystem include everything gave me much more flexibility than breaking out some of it's components --- i.e., the unused spaces in /home, /usr and /var are easily reclaimed if i need more space in /, i can create as many directories as i want without resorting to creative symlinks all over the place, etc. ...

however, there are times i'd at least want some of the sub-directories broken off --- i.e., /var should be it's own filesystem if there is a massive amount of system log activity or if the server is a mail server, /home should be it's own filesystem if you want to contain and enforce quotas on user data, etc.

you need to figure out how you folks want to support the server and how the server is going to be used in the long term so you'll know your better if you want to split out sub-directories into their own filesystems ...

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.
