With HyperMetro double write, if a local write succeeds and a remote write fails, is the business terminated?

Understand the Problem

The question is asking about the behavior of HyperMetro double write technology in a scenario where a local write operation succeeds but the corresponding remote write operation fails. Specifically, it asks whether the business operation would be terminated in such a case. Understanding the fault tolerance mechanisms of HyperMetro is key to answering this.

Answer

The business is not necessarily terminated. The storage arrays determine if the dual-write was successful.

Based on the search results, in a HyperMetro dual-write scenario, the storage arrays determine the success of the dual-write. If a local write succeeds but a remote write fails, writing to the target LUN fails, but the search snippets do not explicitly state that the business is terminated. More information is needed.
