pool member acitve/inactive in 9.x?

I think you are looking for the following method:

MemberObjectStatus[][] LocalLB::PoolMember::get_object_status(
    in String[] pool_names
);

This will return a list of the pool members for the specified pools along with the Enabled or Disabled state of that member. You might want to also check the monitor status (result of health monitor checking) which is available in this method:

MemberMonitorStatus[][] LocalLB::PoolMember::get_monitor_status(
    in String[] pool_names
);
