I recieved 2 speedy responses:
If what you mean is "can I drive the installation of V5.1A onto my
spare disk while V4.0G is up and running on the primary disk", the
answer is "no, won't work".
Many of the steps in the installation procedure only work if you've
got the "install" kernel running; there are things that need to work
in the V5.1A installation that a V4.0G system can't support at all.
In other words, forget about it.  Won't work.

The only install methods are CDRom or RIS server.  The RIS server 
must be
running V5.1A

Original question:
I have a DS20 with 2 disks. The first disk has 4.0g (it's the boot
disk). I want to install 5.1a on the empty 2nd disk. Can I do this
while the system is running 4.0g? In other words, how can I perform a
clean install of 5.1a without booting from the CDROM?

Thanks for the explanation. But would it be possible to do the 
install in an ES40, and then move the disk to the DS20e, boot generic 
and configure a proper kernel?
I want to upgrade my DS20e, but with minimum downtime. Ideally,  I'd 
like to build a 5.1a disk elsewhere, and just plug it into the DS20 
( happen to have a spare ES40 for this).

this is too bad since it would have reduced down time quite a bit.

This works quite well indeed. The domain name is simply a pointer to 
the device which has the domain. You can call it anything you want as 
long as you have appropriate entries in /etc/fdmns. The file set 
names in the domain must match whatever you specified during the 
mkfset command though.

I think that 1 TB is the max for a disk device currently. The next 
release of the OS should increase this to 2 TB. But it all depends on 
the file system that you want to put on it. UFS  has a limit of 1 TB 
I think. Advfs has a limit of 1 TB per file set, but you can have 
multiple filesets.
