I have inherited an 80 machine cluster and need to change root on all of them. Any ideas on an automated way to do that?

Assuming a stronger password, would this be a reasonable method for changing the passwords across all the machines. I have a list of all the machines and I was just going to iterate through the list and rsh to each.
Code:
#!/bin/sh
for i in `more machine.txt `
do
echo $i
rsh $i echo "root:123" | chpasswd
done

If you have to type a password for each server with rsh, use ssh (you might need the -n option with it) instead. Otherwise, I think the method you have chosen is perfectly reasonable.
You need to quote the command, I think, otherwise chpasswd will be run locally.
i do not have root on a solairs 10 server , however i do have the root role, i was wondering if I can change the root password as a a role with the passwd command? I have not tried yet.
and do i have to use the # chgkey -p afterwards?
i need to patch is why i am asking.
