Abstract: A data management method and system for migrating a data volume from a source array to a destination array includes receiving an indication of a source volume to migrate from the source array to the destination array wherein the source volume comprises a clustered volume associated with a plurality of cluster hosts. A path-flip is performed by the host multipath module, to switch the paths between source and destination array. This switch is done in a seamless manner, without disrupting host I/O. The path-flip includes transferring associated metadata from source to destination and can be performed even in clustered and/or multi-host environments. Sanity timers are built-in to ensure that the path-flip completes within a stipulated time-frame and, if not, the path-flip process is aborted and I/O is resumed without any disruption.

Abstract: A method and system perform a background copy of a source volume to a migration volume. The source volume has an asynchronous replication relationship with a disaster recovery (DR) volume. A migration volume snapshot may be obtained and host I/O to the source volume may be disabled. A post-copy replication of the source volume is performed to synchronize the source volume and the DR volume. A replication snapshot, comprising a snapshot of the DR volume, is obtained and an identifier of the replication snapshot is modified in accordance with an identifier of the migration snapshot. For example, the identifier of the migration snapshot may be copied to the replication snapshot. Thereafter, an existing replication relationship between the source volume and the DR volume may be disabled and a post-migration replication relationship between the migration volume and the DR volume established such that subsequent replication are incremental or delta replications.

Abstract: A size-adjustable windshield wiper assembly includes a flexible vertebra, a wiper strip, and a curved spline. The flexible vertebra has scores on an upper side of the flexible vertebra for enabling a user to size the flexible vertebra to a desired size. The wiper strip may include grooves for connecting the wiper strip to the flexible vertebra. The curved spline is inserted into a cavity between the underside of the flexible vertebra and the wiper strip, thereby causing the flexible vertebra to form a curve shape such that the wiper strip is capable of closely hugging a surface of a windshield.
