Is it possible to have a preferred master in a hot-standby setup?

Is there any way to define a preferrred master running a pair of ServerIrons in Hot-Standby mode? Something similar to VRRP-E priorities and preemption.

Yep - this is possible. Please have a look at the following command (which is a global one):

server backup-preference <minutes>

You have to add this to one of the ServerIrons in hot-standby mode. The one with the backup-preference setting is always going to be the master in a hot-standby setup. The ServerIron with the preference setting is not going to assume the master role right away if it is coming up - it is going to wait the specified amount of time (5-30 minutes).
