Priority Group Activation, why use it?

Steven, I don't recall the particular example in the f5 university but I wonder if it's not made itself as clear as it could have re PGA.

The thing missing above is the Priority configuration for an individual pool member that PGA uses. So, you could enable PGA for less than 2 and then you would assign a Priority to each pool member. In a pool of 3 you may have Priority 10 for pool members A and B but Priority 5 for pool member C. In this instance with all pool members active only pool member A and B would be in use and serving traffic. If pool member A went down, however, and with PGA set to less than 2, the big-ip would introduce pool member C to serve traffic, along with B. When pool member A is back online/active then pool member C is dropped again to being redundant.

Does this make sense? Examples of where you might use this is you could have a pool member configured with just a holding page so if the other pool members are down then the user would still see something i.e. a page say Maintenance, for example. Rather than no pool members available and a 404 error.

Hope this clears things up a bit.
