Marking a VIP down via an iRule

Hi ant8344,

 

 

The easiest way to accomplish what you are looking to do is to create another monitor to apply to the server pool and then require that all Health Checks be successful in order for the server to be considered alive.

 

 

In your case you could so something like Enable TCP Print Services (which runs on port 515) on the servers. Then create a TCP Monitor for that port and apply it to the pool.

 

 

So when you want to take a server down for maintenance you stop the TCP Print Services on the server causing the device to fail the health check and be marked down.

 

 

Run your maintenance normally and start the service when you are done.

 

 

You can do this with an iRule, but I have found that this type of method is more reliable and preferable. If you are still interested in an iRule approach look here:

Hope this helps.
