Say /dev/???? is the new drive.  You can do this at your friendly
neighborhood root prompt:



# telinit 1     [or whatever the IRIX method of switching to runlevel 1 is]
# mkdir /drive2
# mount /dev/???? /drive2
# ( cd /usr; tar cv . ) | ( cd /drive2; tar xvp )

[obviously you want to check carefully to make 100% sure everything's there
& safe & the permissions are right before you do this next part]

# rm -rf /usr/*
# umount /drive2
# mount /dev/???? /usr

[...and modify /etc/fstab to reflect that last part]

Of course, you may want the stuff in /usr to be in a subdirectory of this
new drive (as opposed to the root), so you'd do a 'mkdir /drive2/usr' before
moving everything over, replace "/drive2" in that tar command with
"/drive2/usr", and then instead of mounting the new drive directly to /usr,
you'll replace those last three commands above with:

# rm -rf /usr
# ln -s /drive2/usr /usr

That should be pretty seamless -- at least it is under linux.  (And, again,
modify /etc/fstab so it mounts your new drive, if you haven't already.)
