Setting up node priority

Hello,

 

I have a requirement to setup an active/passive configuration on a LTM where the passive node only becomes active after the active node is down for ~10 mins.. I'm familiar with setting up priority activation on a pool and setting the priority on the nodes, just not finding where I can setup a timeout value... Any suggestions would be great..

 

Thanks Brian

    Hi, If you've already configured priority group activation properly, you just need to change your health monitor settings and set the Timeout value to 601, the monitor will then mark the node down if it still fails after 10 minutes + 1 second.

     

    However, 10 minutes is an unusual timeout for me and I'm not sure if you need to follow the F5 recommended formula for Interval/Timeout settings which is:

     

    Timeout = (3 x Interval) + 1

     

    You may need to check the service more often than the resulting 200 seconds interval. It depends on your specific case.
