iRule pool selection after checking

Question

Hello,&nbsp;&nbsp;
Kindly i need some assistance to complete part of the iRule. i have a LC and i want to  select a pool member based on source address. But first i want to check if the pool member is up before, otherwise i will select the whole default pool.&nbsp;
&nbsp;part of the iRule is:&nbsp;
&nbsp;when CLIENT_ACCEPTED {
&nbsp;  if { [IP::addr [IP::client_addr] equals 10.10.10.10] } {
&nbsp;  if {[check if the pool member 1.1.1.1 is up }{ ----------&lt;&lt;&lt;&lt;&lt;&lt; how to write it?
&nbsp;      pool default_pool member 1.1.1.1
&nbsp;  } else {
&nbsp;      pool default_pool }
&nbsp;}&nbsp;
&nbsp;Do i need another function LB::SELECTED to make it work.&nbsp;
&nbsp;Regards,
&nbsp;George&nbsp;&nbsp;

can you try LB::status?

Try something like: set p my_pool_name
set m my_pool_member_ip:port
if { [active_members $p] &gt; "0" } {
    if { [lsearch -exact [active_members -list $p] $m] } {
      pool $p member $m
    } else {
      pool $p
    }
}

Thank you. I will try the code. 
&nbsp; But while searching for every part of the line " if { [lsearch -exact [active_members -list $p] $m]" to understand it, I read that the option "list" in the active_member is not supportive in the GTM. 
&nbsp; Do you think LC also do not support this option? 
&nbsp;

If you can't do active_members, can you do priority group activation?

Hi Chris, 
&nbsp; Since i have a Link Controller, in which i faced a problem (a bug) when using the same node  in multiple pool, so i cannot use the same node in multiple pool. I am trying to use the default_gateway pool and play on it. 
&nbsp; Otherwise, I could have created a pool including one node and check if this pool is up, without getting into this delimma 
&nbsp;  
&nbsp; All what i want is to check if a pool member is up in a Link controller license box.... 
&nbsp;  
&nbsp; Regards, 
&nbsp; George
