A data migration is being planned from a Hitachi to a PowerMax using Open Replicator. Which flag is used to protect against SAN failure?
To protect against SAN failure during a data migration from a Hitachi to a PowerMax using Open Replicator, the 'Donor Update' flag is used. This feature ensures that any writes to the local device are also propagated to the remote device, maintaining data consistency between the two in the event of a connectivity issue. This way, no new data written to the local device is lost during a SAN failure.

Open Replicator includes a feature that protects against potential data loss due to a SAN failure or other connectivity problems during an active Open Replicator live pull session. The “donor update” feature enables arrays to propagate (update) writes to the local device back to the remote device (donor) as data is being pulled from the remote device. When enabled, donor update ensures consistent data between, and on, both the local and remote devices during the data movement process. As a result, no new data written to the local device will be lost during a SAN failure. https://www.scribd.com/document/685136739/6-Open-Replicator-and-Flm-Fundamentals
