34 Protecting an Exchange Cluster with a Like-Named Cluster

8. If you want to modify DNS configuration options, click Configure. The Configure DNS Failover window will

appear.

9. On the

Configure DNS window, you can modify the TTL value for the DNS record. You can also specify the

user credentials needed to modify DNS. When you are finished, you can click

Test to test the DNS

configuration for the selected DNS server(s), or click

OK to return to the Configure Protection window.

NOTE: Decreasing the TTL value will increase the speed at which clients get the updated information.

10.After you have changed the configuration parameters, click OK to apply the settings and return to the

Manage Exchange window. If you click Cancel, any changes you have made will be discarded and the

previous configuration parameters will be used.

11.Click

Validate to validate the selected cluster pair. The validation proceeds exactly like validation for other

methods of failover.

12.Click

Enable Protection to enable protection for the source cluster.

Enabling protection

After protection is enabled, the Storage Mirroring Application Manager creates four resources on the target

cluster: two generic script resources, an IP address resource, and a temporary name resource. The temporary

name resource is the source EVS name with “_LN” appended to the end. The Application Manager uses the

temporary name resource for the connection between the source and target clusters. The Application Manager

gets the order of the source cluster resources from the Microsoft Cluster DLL, then builds the scripts with the

resources in order and based off the source’s resources configuration.
