downing a member from LB_FAILED

Hi all,     I'm trying to write an iRule that will down a member in LB_FAILED. I figured this would be a good spot to do it, since LB_FAILED is reached if a selected member is unreachable ...

Hi Matt,

 

 

I would have expected that LB::server commands would return info for the "currently selected" pool member even if the connection failed. If a member couldn't be selected because no pool member was up, then it would seem logical that LB::server * could only return the pool name. I could see why the IP::server_addr/TCP::server_port commands wouldn't return anything in LB_FAILED because no connection was established to the pool member.

 

 

Maybe this is a bug? There have been quite a few issues with using commands in LB_FAILED over the past versions. However, from a post post, someone was able to at least get the LB::server addr and LB::server port values in LB_FAILED (in 9.3.x):

rshayne, do you have any pool members not marked down in the pool when you're testing?
