Prerequisites for configuring a CCR-enabled Storage Group

Ensure that you enable the Continuous Cluster Replica (CCR) feature on the Exchange server, the cluster continuous replication Storage Group copy is seeded and is healthy, SnapManager is installed on both nodes of the CCR, and the CCR active and passive nodes have identical dedicated LUNs before configuring a CCR-enabled Storage Group.

Before you plan to configure and migrate the CCR enabled Storage Group, ensure that you meet the following system requirements:

The CCR feature is enabled on Exchange Server 2007.
For more information about how to enable CCR on your version of Exchange Server 2007, see the Microsoft documentation for Exchange Server 2007.
SnapManager is installed on both nodes of the CCR.
The cluster continuous replication Storage Group copy is seeded, and it is in a healthy state.
For more information about how to seed the databases in a CCR environment, see the Microsoft documentation for Exchange Server 2007.
The CCR active and passive nodes have identical dedicated LUNs, with the same drive letter or mountpoint path.
If a LUN exists only on one node, it cannot be used by CCR databases.

Note: Try to give the same LUN on each node the identical volume layout for the storage system. If LUNs E, F, and G on Node A are sharing a volume, LUNs E, F, and G on Node B also must share an identical volume.
