Abstract:
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.
