I have decided to post the configure script for rc.lvs_dr, the rc.lvs_dr
script and it's output (rc.lvs_dr.out) here and let you see from it what
is happening.
One of my coworkers went down to our datacenter and plugged in the
additional nic, but somewhere along the line unpluged or turned of one of
the realservers so please just ignore the fact that
prod-zope-atl01.dmz-atl.bogus isn't replying to a ping... that's
explainable.
The thing that's puzzling me is this error:
SIOCSIFNETMASK: Cannot assign requested address
SIOCADDRT: No such device
I added four lines to the rc.lvs_dr script, one comment and an if block
with an include for the attatched include (which dumps the date and
redirects stderr to stdout so that we can get all the info in the output
file.
here is the output of the script:

ntpd not running, won't be restarted
The location of the output files rc.lvs, mon.cf and ntp.conf is the
default = ./
You can change this by editing the variables $rc_lvs_home, $rc_mon_home,
$rc_ntp_home
Remember to run this rc.lvs script on the real-servers too.
This script will use ssh to do this for you if you run it with
./configure lvs_xx.conf -i

the realservers IPs are in the script (among other things) so that the
script knows whether it's running on a director or realserver.

In that case you'll need a route.
