NimbostratusMaintenance page redirect with LC/LTM
I find myself in a bit of a catch-22. I have a LTM site that I want to redirect requests when no pool members are available. I can do this fairly simply with an iRule using active_members == 0 with an http:redirect to the maintenance page. However, this site also sits behind Link Controller. When no pool members are available, link controller disables the virtual server, ergo, the iRule is never called because no traffic gets passed to the site.
What am I missing?

There are a few ways of getting around this, depending what your situation is.
1.
Put your current pool members in a high priority group, and your destination redirect server in a low priority group. The latter will get used when your normal servers are down.
or
2.
Set up a separate virtual server that does the HTTP redirect and have this server as the sole member of a low priority group (similar to 1 above) in the server pool of your main virtual server.
You need to configure an appropriate health monitor obviously.
