Hi!

Assume that 10.0.0.1 is the primary server and 10.0.0.2 is the fallback this should work (per request):

when HTTP_REQUEST_SEND {

    if { [LB::status pool poolname member 10.0.0.1 80] equals "up" and [IP::addr [LB::server addr] equals 10.0.0.2] } {
        reject
    }
}

If you have more than one server in the priority group, just add some "or" to the if statement.
