Can LTM be used to configure Active and Passive Servers?

For a given vip is it possible to define pool of servers that are active and also some pool of members that passive. Basically this is what I want to do:

 

 

1. Define active pool of servers for a vip

 

2. Define passive pool of servers for a vip

 

3. When all the members in pool go down then make passive pool active

 

 

Is it possible to do that in LTM?

 

 

If it's possible then when one of the pool members (previously active) become active again does it switch it back?
