High Availability

[Aadolf]

hello all
In HA scenario,should services be  activate both on master and backup or administrator should activate services in System: High Availability: Status page??
Example:
I set HA for 2 server then i enable IDS.Now when i check System: High Availability: Status page there is an item for IDS with stop status icon.I  check backup server and find out the configuration is sync.
is it a problem in HA or its a duty for administrator to enable or disable service for backup server while master is active.
