Abstract:
Method and system for replacing a first node and a second of a clustered storage system by a third node and a fourth node are provided. The method includes migrating all storage objects managed by the first node to the second node; replacing the first node by the third node and migrating all the storage objects managed by the first node and the second node to the third node; and replacing the second node by the fourth node and then migrating the storage objects previously managed by the second node but currently managed by the third node to the fourth node. The nodes may also be replaced by operationally connecting the third node and the fourth node to storage managed by the first node and the second node; joining the third node and the fourth node to a same cluster as the first node and the second node.
