Hi,

Natively you can't do it but using an irule it's possible:

can you try the following irule (I don't test it, keep me in touch)

when CLIENT_ACCEPTED { 

set mypick [LB::select]


 If we have both node UP we force traffic trough node 1
if { {[active_members poolName] == 2} } {

     First node 
    if { [LB::status pool prod_443 member 1.1.1.1 443] eq "up" } { 
        pool prod_443 member 1.1.1.1 
     second node
    } elseif { LB::status pool prod_443 member 2.2.2.2 443] eq "up" } {
        pool prod_443 member 2.2.2.2
    } else {
        eval $mypick
    }

}
}

Regards
