A.4 Synchronizing IDM Drivers
After creating BCC-specific IDM drivers and SSL certificates, if you are adding a new cluster to an
existing business continuity cluster in a multiple eDirectory tree BCC, you must synchronize the
BCC-specific IDM drivers for the Cluster and User objects. If BCC-specific IDM drivers are not
synchronized, clusters can't be enabled for business continuity. This is not necessary unless you are
adding a new cluster to an existing business continuity cluster.
To synchronize BCC-specific IDM drivers:
1 Start your internet browser and enter the URL for iManager.
The URL is http://server_ip_address/nps/iManager.html. Replace server_ip_address with the
IP address or DNS name of the server that has iManager and the IDM preconfigured templates
for iManager installed.
2 Enter your username and password.
3 In the left column, click DirXML, then click the DirXMLOverview link.
4 Search for and find the BCC driver set.
5 Click the red Cluster Sync icon for the driver you want to sync, then click the Migrate from
eDirectory button.
6 Click Add, browse to and select the cluster object for the new cluster you are adding, then click
OK.
Selecting the cluster object will cause the BCC-specific cluster IDM drivers to synchronize.
7 If you chose to include User object synchronization, repeat the above steps, and in
the User Sync icon.
A.5 Preventing IDM Synchronization Loops
If you have three or more clusters each in separate eDirectory trees in your business continuity
cluster, you should set up IDM user object and cluster resource object synchronization in a manner
that prevents IDM synchronization loops. IDM synchronization loops can cause excessive network
traffic and slow server communication and performance.
For example, in a three-cluster business continuity cluster, a IDM synchronization loop occurs when
Cluster One is configured to synchronize with Cluster Two, Cluster Two is configured to
synchronize with Cluster Three, and Cluster Three is configured to synchronize back to Cluster One.
This is illustrated in Figure 2-3 below.
