I'm looking at LB_FAILED and the other LB global commands, but I cannot suss out how to define what I need. This is one of my first cracks at iRules, and I need some guidance.
Thank you!

You can use priority on the members of a pool to achieve this. Set the member you want to receive requests to 100 for example. Then set the second member to 10. The member set to 100 will receive all requests unless it gets marked down.
You can get more detail on priority groups in the LTM configuration guide on AskF5 (Click here).
The config guide shows the configuration as it appears in a file. But you can also set this up in the GUI under Local Traffic | Pools | pool_name | Members.

NimbostratusHi ..
What happens if the pool member in different data center
NimbostratusStill you can run that if the routing does not have any issue.
NimbostratusHi, can we achieve same host availability across Data center. For Example, I have a host configured in DC1, same hostname with the different IP address in DC2. Can i set F5 LTM such a way, when host on DC2 should come up only when the host on DC1 is down. ( Note: there are other members also in the LTM pool)
NimbostratusYes, You can achieve it with priority group activation where you can add pool members DC 1 with higher priority and DC 2 with lower Priority.
NimbostratusOk, thanks for the reply, actually its not for all the pool members in the pool. Only one pool member which is Primary VM needs to be configured for Active / Passive setup.
