can you try "1 any virtual"?

e.g. 

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
}
[root@ve10:Active] config  b pool foo list
pool foo {
   members {
      200.200.200.101:80 {}
      200.200.200.102:80 {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
        persist uie 1
}
}

[root@ve10:Active] config  b rule mybackup list
rule mybackup {
   when CLIENT_ACCEPTED {
   set p [persist lookup uie {1 any virtual}]
   if {[scan $p "[LB::server pool] %s %d" ip port] == 2} {
      foreach m [active_members -list [LB::server pool]] {
         if {$m ne "$ip $port"} {
            pool [LB::server pool] member $m
            break
         }
      }
   } else {
      reject
   }
}
when SERVER_CONNECTED {
        log local0. "[IP::remote_addr]:[TCP::remote_port]"
}
}

[root@ve10:Active] config  b persist
