<p><font face="monospace">Hi,<br>
</font></p>
<p><font face="monospace">Actually, I would recommend starting with
"backup / backup" (!!) to prevent exactly the scenario you
described above, where you take down the former-active node for
maintenance, yet it boots in "active" mode, completely opposite
to the state of the VIP.</font></p>
<p><font face="monospace">Now, in order to fix the state where both
tags are in "backup" mode, you'd deploy an external check-script
that periodically scans the tag statuses and fixes a "backup"
tag to "active" whenever a box owns the VIP.</font></p>
