This section describes how to view information about an existing remote replication consistency group, so that you can effectively monitor the status of the consistency group.
Context
- On the remote replication consistency group management page, click
to refresh remote replication consistency groups. - On the remote replication consistency group management page, click
or 
next to a parameter and enter a keyword or select a parameter value to search for desired remote replication consistency groups. - On the remote replication consistency group management page, click
and select desired remote replication consistency group parameters to be viewed.
Procedure
- Choose Data Protection > Protection Entity > Protection Group > Remote Replication Consistency Group.
- 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
Name of a remote replication consistency group.
ID
ID of a remote replication consistency group.
Health Status
Health status of a HyperMetro consistency group. Possible values are as follows:
- Normal: A remote replication consistency group is working properly, and data can be synchronized.
- Faulty: A remote replication consistency group or replication link is faulty, and data cannot be synchronized.
- Invalid: A remote replication consistency group cannot be used or restored and can only be deleted.
Running Status
Running status of a HyperMetro consistency group. Possible values are as follows:
- Unknown: The system fails the query.
- Normal: Data in a consistency group has been synchronized.
- Synchronizing: Data in a consistency group is being synchronized.
- Split: A consistency group has been split and data synchronization is paused.
- Interrupted: A remote replication internal I/O error occurs or the replication link is down, and you cannot perform the synchronization operation temporarily.
- To be recovered: After the remote replication internal I/O error is rectified or the replication link is up, and if Recovery Policy is set to Manual, the consistency group enters this state. You need to manually start data synchronization for the pairs.
- Invalid: A consistency group cannot be used and restored. You can only delete the consistency group from both primary and secondary sites. Otherwise, further consistency group creation operations may fail.
Replication Mode
Data replication mode of a remote replication consistency group.
- Asynchronous: After data is written to the primary resource successfully, the host receives a write success response. At the same time, 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 foreground applications.
- Synchronous: When data is written to the primary resource, the write request is also sent to the secondary resource. The host receives a write success message only after the data is written to both primary and secondary resources successfully, ensuring that data on the primary resource and secondary resource is synchronized in real time.
Local Resource Role
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
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
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).
- Optional: Click
