Upgrading server hardware on existing failover pair

[Oscar Ricardo Silva]

To gracefully bring down the server and notify the partner I use this 
script:

#!/bin/sh
omshell << EOF
connect
new control
open
set state = 2
update
EOF


which I found at <http://barryp.org/blog/entries/dhcp-failover/>.  If 
you look at the logs of the server that stays up you'll see that it gets 
the notification and moves into a "partner-down" state.
