Migrating data to a new diskAlthough the Server Cluster Recovery Utility was designed to make recovering from disk failures easier, it can be used in other ways. In particular, the cluster recovery utility can be used to migrate data from one cluster disk to another.
Consider, for example, a cluster that has a set of disks attached to it. Initially, a small disk array may have been sufficient for the application, however, over time the application requirements may grow and a new, high performance disk array may be required. A new disk drive or logical disk can be exposed to the cluster and a physical disk resource created. This physical disk resource can then be substituted into the application dependency tree using the same procedures described in section Recovering a cluster disk.
