mark a node down in one pool only?

Can you define what you mean by a "node"? In terms of the BIG-IP the top level object is a Virtual Server. The VS has an attribute of a single default pool that it serves traffic to. A pool can contain many pool members.

 

 

A Node is most typically referred to as a backend server ip address. A Pool Member is a combination of a node's IP address and a specific port on that node.

 

 

I'm a bit confused by your statement about a node servicing two or more pools. If you mean to use Virtual Server instead of node, a Virtual Server has only one pool as an attribute. Of course you can override this with iRules, but it's not part of the core configuration.

 

 

I'm sure the answer is yes to your question as you have full control of enabling/disabling objects at all levels (ie. a single pool member within a pool). But, if you disable the one and only pool to a virtual server, there will be no where to send the traffic to.

 

 

If you could clarify your question with your specific configuration, we can let you know how to get it done and what methods to use.
