"Check Until Up" Monitor Setting Missing?

Specifies the period of time a monitor waits after marking a pool member down, before the monitor requests status from that pool member. If you specify a value of 0  (zero), once the inband monitor marks a pool member down, that pool member is not marked up without outside intervention, either by explicitly marking the pool member up, or by using by using the Check Until Up  setting in any other monitor (except another Inband monitor) configured on the same pool member. (In this case, the other monitor is known as the active monitor, and the Inband monitor is known as the passive monitor. If you have this active-passive monitor configuration, do not set Retry Time to a value other than zero. For this active-passive monitor configuration, the active monitor should be the one to mark the pool member up, and setting a value here could result in a possible conflict between two separate processes marking a pool member up at different times.) The default is 200 seconds.
