Modifying Properties of a Remote Replication Consistency Group

Precautions

After the properties of a remote replication consistency group are modified, the properties of pairs in the consistency group remain unchanged. However, the working properties are consistent with those of the consistency group.

Procedure

1. Choose Data Protection > Block Protection > Remote Replication Consistency Group.
2. Click More on the right of the desired remote replication consistency group and select Modify.

   The Modify Remote Replication Consistency Group page is displayed.

3. Modify properties of the remote replication consistency group. Table 1 describes related parameters.

   Table 1 Remote replication consistency group parameters

   Parameter	Description
   Name	Indicates the name of the remote replication consistency group. [Value range] The name must be unique. The name can only contain digits, letters, underscores (_), and hyphens (-), and must start with a digit or letter. The name contains 1 to 31 characters.
   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).
   Recovery Policy	Indicates whether the system automatically synchronizes data after a remote replication fault is rectified. [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.
   Synchronization Method	Indicates the data synchronization mode between primary and secondary resources. Possible options are as follows: Manual: Data must be manually synchronized between primary and secondary resources. Timed wait after synchronization begins: The system starts timing as soon as the latest synchronization begins. When the time specified in Interval has elapsed, the system automatically starts to synchronize data between primary and secondary resources again. NOTE: If the latest synchronization is still being executed after the time specified in Interval has elapsed, data synchronization will start after the latest synchronization finishes. Specific time policy: The system automatically synchronizes data between primary and secondary resources based on a specific time policy.
   Interval	Set Timed wait after synchronization begins. [Value range] An integer ranging from 1 to 1440, when minutes is used as the unit. An integer ranging from 10 to 86,400, when seconds is used as the unit. NOTE: This parameter is available only when Synchronization Method is set to Timed wait after synchronization begins.
   Time Policy	The system automatically synchronizes data between primary and secondary resources based on a specific time policy. [Value range] Daily: Data synchronization begins on every day. Its value ranges from 00:00 to 23:59. Hourly: Data synchronization begins in every hour. Its value is an integer ranging from 0 to 59. NOTE: This parameter is available only when Synchronization Method is set to Specific time policy.
