Assume a storage system utilizing HyperClone experiences a logical fault on the source LUN. What is the procedure to restore service on the source LUN?
Understand the Problem
The question describes a scenario where a storage system using HyperClone has a logical fault on the source LUN (Logical Unit Number). The question asks about the correct procedure to restore service on the source LUN. The options provided outline different methods, and we need to identify the most appropriate method to restore the source LUN using HyperClone.
Answer
Reverse synchronize data from the target LUN to the source LUN to restore service.
To restore service on the source LUN after a logical fault in a HyperClone setup, you can perform a reverse synchronization from the target LUN back to the source LUN. This will overwrite the corrupted data on the source LUN with the consistent data from the target LUN, effectively restoring the service.
Answer for screen readers
To restore service on the source LUN after a logical fault in a HyperClone setup, you can perform a reverse synchronization from the target LUN back to the source LUN. This will overwrite the corrupted data on the source LUN with the consistent data from the target LUN, effectively restoring the service.
More Information
HyperClone is a feature that creates a clone (copy) of a LUN (Logical Unit Number) for data protection or migration purposes. If the original (source) LUN experiences a logical fault, the replicated (target) LUN can be used to restore the source LUN.
Tips
Ensure that the target LUN is consistent and available before initiating the reverse synchronization to avoid further data corruption.
