After a remote replication consistency group is created, if one remote replication task is faulty, other tasks in the consistency group run normally without waiting for the faulty task to recover.
This question addresses the behavior of remote replication consistency groups in Huawei storage systems, such as OceanStor Dorado or Pacific series. According to the *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)*, a consistency group ensures that multiple remote replication tasks operate as a single unit to maintain data consistency across LUNs or volumes. The material states: “In a remote replication consistency group, if one replication task fails (e.g., due to a link failure or configuration issue), the entire consistency group is affected, and other tasks do not continue running normally. The system suspends all tasks in the group to preserve data consistency until the faulty task is resolved or manually split.” This ensures that dependent data sets remain synchronized. Therefore, the statement that other tasks run normally without waiting for the faulty task is false, as the consistency group halts all tasks to maintain integrity.
