To set up the Exchange group on the secondary site

1. On the secondary site, ensure that you have set up the cluster disk groups and dynamic volumes to match those on the primary site.
2. Ensure that you have created the Volume Manager Disk Group resources that correspond with the Exchange disk groups.
3. Ensure that the disk groups are online and volumes mounted on the node where you are going to run the RecoverCMS command.
4. Change to the directory where you installed Exchange.
5. Run the RecoverCMS command, using the following syntax:

   Setup.com /recoverCMS /CMSName:<name>/CMSIPaddress:<ip>

   Where <name> is the name you assigned to the Exchange server during installation on the primary site and <ip> is the IP assigned during Exchange installation on the primary site.

   You may receive an error message due to a Microsoft issue that states the command failed to bring cluster resource Network Name online, and that the group or resource is not in the correct state to perform the requested operation.

   In this case, complete the following steps on the secondary site:

   • On the secondary site, using the Failover Management console, bring the clustered mailbox server (Network Name) resource online manually.

   • After the Network Name resource comes online, take the IP resource offline. (This will also offline the Network Name resource.)

   • Delete the Network Name resource and the IP resource.

   • Run the RecoverCMS command over again. This time it will succeed and all the Exchange resources will be created on the secondary site.

6. On the secondary site, bring the Exchange cluster group and its resources offline.
7. On the primary site, bring the Exchange cluster group and its resources online.
