iRule to isolate node

Thank you! If primary is offline, yes corp can \ should use secondary nodes. The two pool solution sounds good.

As I understand it, I should leave the pool that contains all members as the default pool for the virtual server, and then the iRule would handle the redirect to the pool that contains only the primary server.

At the pool level, the Priority Group activation should be set to "less than" 1 available member for the "new" primary only pool, but for the pool the contains all the nodes, Priority Group activation should remain disabled?

Sound correct?

Thanks again.
