Hi Managers,
Thank many of you who responded to my email quickly.
After I sent my email, I dug out the command that I want.
disklabel -r to save my disk configuration and
disklabel -r -R to make it bootable.
However, that works for 4.0x systems. As pointed by Dr. Thomas Blinn,
V5 names disk a little differently.
After I took away the old disk and make the new disk SCSI 0, and I
start the system, but system fail to mount /usr, because V5 still makes the
my new disk dsk2 rather than dsk0. I have to boot to single user mode and
modify /etc/fstab for /usr. After I reboot, I notice that disk swap was not
turned on. I have to modify /etc/sysconfigtab as pointed by Tom again.
Anyway, I think that I know what I need to do next time for the V5 root
disk swap (or any other disk).
I would like to thank these folks:

alan@nabeth.cxo.cpqcorp.net
Adametz, Bluejay" <bluejay@fujigreenwood.com
(who also points out how using dsfmgr hwmgr to rename my dsk2 back to dsk0, which I have not
tried yet).
I also included Dr. Blinn's email
