Once the CMS has stopped, start recovery on mb100 with the setup command:
Setup.com /RecoverCMS /CMSName:mb100ccr /CMSIPAddress:192.168.1.80

5. For CCR clusters storage group replication is suspended at this point. If the passive node does
not contain a good copy of the database and logs, then reseed with Update-StorageGroupCopy
from the passive node (mb101).
Update-StorageGroupCopy -Identity ???mb100ccr\First Storage Group???
-DeleteExistingFiles
6. Reconfigure the backup site to reestablish ca100 as the SCR target. The cluster configuration
information needs to be removed from ca100.
Setup.com /ClearLocalCMS /CMSName mb100ccr
7. Verify the cluster information was removed successfully using Cluster Administrator. Re - enable
ca100 as the SCR target.
Enable-StorageGroupCopy -Identity ???mb100ccr\First Storage Group???
-StandbyMachine ca100
At this point the original cluster is running and SCR is available for site resiliency.
Summary
This chapter detailed how to add high availability by using new features in Exchange Server 2007. It is
important to understand that high availability is much more than adding CCR, LCR, or SCR. High
availability is only achieved by process, people, and technology. In fact, because of the complexity of
these high - availability solutions, companies without good processes and people may actually find less
availability after implementing clusters.
