Change LB priority based on status

Hi ,

I only tried this backup method with priority group activation, but it will not work like this

FOR Eg :) if server A have high priority

• When both servers are available:
  • Traffic is directed to the server with the highest priority (e.g., Server A).
  • Server B (lower priority) remains on standby and does not receive traffic unless Server A fails.
• If Server A goes offline:
  • Server B (backup) starts receiving traffic because it becomes the highest available priority member.
• If Server A comes back online:
  • Traffic automatically returns to Server A due to its higher priority.

This is an option for backup server(if you need both servers accept connection, this is not expected solution)

Also could u please check manual resume is fine for u, its more near for your request. - Overview of the Manual Resume feature for BIG-IP LTM monitors

Try this as well in your servers

Hiii neeeewbie

can you paste the configuration of the pool here?
In theory, the server A needles high priority for always be a first server in response first

neeeewbie I don't believe this is possible with just the LTM. I believe what you would really want is a GTM to server 2 virtual servers, one with server A in the pool and one with server B in the pool. Once you have that configuration in place you would set the GTM to balance DNS queries between the two sites and only give one site or the other if the opposing site virtual server failed. Maybe it's possible with TCL in an iRule but I don't believe anything exists that would have a running tally like you would need in order to flip back and forth between pool members.

you can use Manual Resume feature.

enable it in the health monitor attached to pool
