Abstract:
A storage object is migrated between nodes by a source node automatically verifying that another node is configured to service the storage object and changing ownership of the storage object based on the verifying. A cluster manager for the clustered storage system receives a request and provides the request to the source which owns the storage object. The source verifies that the destination is configured according to a predetermined configuration for servicing the storage object. Based on the verifying, the source offlines the storage object and updates ownership information of the storage object, thereafter allowing the destination to online the storage object. The cluster manager further provides the updated ownership information to all the nodes in the cluster, so an access request intended for the storage object may be received by any node and forwarded to the destination using the updated ownership information to effect a transparent migration.
