Patent number: 11650891Abstract: Methods, systems, and computer program products for preventing non-detectable data loss during site switchover are disclosed. A computer-implemented method may include receiving a request to perform a switchover from a first node to a second node, determining whether to place a storage volume involved in the switchover in a suspended state, setting the storage volume in the suspended state based on determining that the storage volume is to be placed in the suspended state, and maintaining the storage volume in the suspended state after completing the switchover. In an example, the storage volume may be placed in a suspended state based on examining a volume-specific attribute indicating whether the storage volume is to be suspended when involved in a switchover. In one example, each storage volume involved in a switchover may be placed in a suspended state when indicated as part of a switchover request.Type: GrantFiled: June 8, 2021Date of Patent: May 16, 2023Assignee: NetApp, Inc.Inventors: Yong Cho, Prachi Deshmukh

Patent number: 10521316Abstract: A system and method for handling multi-node failures in a disaster recovery cluster is provided. In the event of an error condition, a switchover operation occurs from the failed nodes to one or more surviving nodes. Data stored in non-volatile random access memory is recovered by the surviving nodes to bring storage objects, e.g., disks, aggregates and/or volumes into a consistent state.Type: GrantFiled: November 6, 2017Date of Patent: December 31, 2019Assignee: NetApp Inc.Inventors: Vaiapuri Ramasubramaniam, Harihara Kadayam, Parag Sarfare, Yong Eun Cho, Chaitanya Patel, Hrishikesh Keremane, Prachi Deshmukh
