How do I configure the lb for a server failover instead of load balancing? i.e. - traffic keeps being delivered to one primary server unless it is down (then delivers to the backup server) and redelivers to the primary server once it is back online.

Hi,
Under Service Group (where you define your pool of servers) you can assign priority to each server.
Let's say you have 2 servers: S1 + S2.
And let say you configure a priority of S1=2 and S2=1.
As long as S1 is up, all clients will use S1.
If S1 is detected down, S2 will be used.
If S1 comes back, S1 will be used again for new clients connections.
FYI you can do some other pretty cool stuff with priority.
For instance you may want to use "master" servers and only an other group of "backup" servers if the number of servers in the master pool is below a specific threshold.
I let you see our manual for more information and cool stuff around "priority".
