Viewing Remote Replication Consistency Group Information

Procedure

1. Choose Data Protection > Block Protection > Remote Replication Consistency Group.
2. View the basic information of an existing remote replication consistency group. Table 1 describes related parameters.

   Table 1 Remote replication consistency group parameters

   Parameter	Description
   Name	Indicates the name of a remote replication consistency group.
   ID	Indicates the ID of a remote replication consistency group.
   Health Status	Indicates whether a remote replication consistency group is running properly. Possible options are as follows: Normal: The consistency group is functioning properly. You can perform the synchronization operation. Fault: The consistency group malfunctions or the replication link is down, you cannot perform the synchronization operation.
   Running Status	Indicates whether a remote replication consistency group is running properly. Possible options are as follows: Normal: Data has been synchronized in the consistency group. Synchronizing: Data is being synchronized in the consistency group. Split: The consistency group is in split status, and data synchronization is suspended. Interrupted: An internal I/O error occurs or the replication link is down, and you cannot perform the synchronization operation temporarily. To be recovered: After the internal I/O error is rectified or the replication link is up, the consistency group enters this status if Recovery Policy is Manual. You need to manually start synchronization for the consistency group to synchronize data. Invalid: The consistency group is unusable and cannot be restored in this status, except deleting it. You must delete the consistency group on both primary and secondary storage devices. Otherwise, you may fail to create any after the deletion.
   Replication Mode	Indicates the data replication mode of a remote replication consistency group. Asynchronous: After data is written to primary resources successfully, the host receives a write success response. Meanwhile, the primary site records differences between the written data and the secondary resource data. Then the changed data recorded by the primary site is synchronized to the secondary site, minimizing the write latency for upper-layer applications.
   Local Resource Role	Indicates whether local resources of a remote replication pair in a consistency group are primary resources. If local resources are primary resources, it displays as Primary. Otherwise, it displays as Secondary.
   Recovery Policy	Indicates whether the system automatically synchronizes data after a remote replication fault is rectified. The default value is Automatic. [Value range] Automatic: The previous ongoing tasks automatically resume immediately after the remote replication fault is rectified. Manual: The value of Running Status changes to To be recovered after the remote replication fault is rectified. In this case, you can check the system and then determine whether to resume the previous ongoing tasks manually.
   Speed	Indicates the data synchronization speed of a remote replication consistency group. The value ranges from 1 MB/s to 1024 MB/s (or 1024 KB/s to 1,048,576 KB/s). The default value is 32 MB/s.
