This will happen automatically after a while (as described in
<http://cr.yp.to/qmail/faq/efficiency.html#dead-hosts>),
but if you want it to happen immediately, see
<http://cr.yp.to/qmail/faq/admin.html#queuerun>.

Just add the main server's names to control/rcpthosts. qmail-smtpd will
accept the messages and put them in the queue; since you don't have
local delivery rules, qmail-send will try to send them on to the main
server, just like any other remote delivery. Actually, you may need to use
smtproutes to make sure qmail-remote only tries to send to the main server
and not the backup.

Surprisingly, I didn't find the above anywhere. You could try the qmail
mailing list.
hope this helps,
