This topic explains how to restore cluster continuous replication (CCR) functionality after the passive copy has been reported as diverged.

Failures can occur and then be manually or automatically recovered without causing a divergence. A divergence is reported in the event log after CCR has seen significant traffic since the last outage. This can be several megabytes of storage group changes. If a divergence is not reported, the administrator should assume that any issues were automatically recovered by CCR.

To perform this procedure, the account you use must be delegated the following:

  • Exchange Server Administrator role and local Administrators group for the target server

For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.

  1. Determine which node is currently the passive node. You can do this by running the following cmdlet in the Exchange Management Shell:

    Get-ClusteredMailboxServerStatus -Identity:<Server>
    
  2. Follow the steps to seed the passive node that are in the topic How to Seed a Cluster Continuous Replication Copy.
