You can add a single domain controller host or multiple hosts when you register an Active Directory.
You might configure multiple domain controller hosts to ensure redundancy and failover operations. If the primary domain controller that App Volumes Manager is connected to goes down, then App Volumes Manager can perform a failover and switch to a different host. This ensures that App Volumes users are unaffected by the downtime and can continue their operations without interruption.
You can choose how App Volumes Manager detects domain controllers. Consider the following when you add domain controllers:
If you provide a list of domain controllers, App Volumes Manager looks for a domain controller only in the list you provided. If the domain controllers in the list are all down, App Volumes Manager does not search for or detect any other domain controller.
If you do not provide a list of domain controllers, App Volumes Manager detects domain controllers automatically and also assigns a priority to them.
App Volumes Manager will search for and try to connect to domain controllers from the same site. Domain controllers from other sites are also added in order of binding time.
Domain controllers in the same site always have higher priority over those from different sites.
You can view the list of domain controllers and their connectivity status under.
Refresh Domain Controllers
The list of available domain controllers is refreshed every 480 minutes (8 hours). Use the environment variable, TIME_TO_REFRESH_DOMAIN_CONTROLLERS, to change the default time of 8 hours.
You must set the time in minutes.
