node switching

Not sure how to approach this or if it's feasible

 

 

We have 2 standalone windows 2003 servers with an app supplied by a company that can only operate on one node at a time, so looking at a failover approach - both servers are connected to a shared disk resource for the application. Wondering if this is achievable with the F5 kit and if so what methods to use (or pointers to resources please)
