Modifying Properties of a Remote Replication Pair

Precautions

The properties of a remote replication pair which has been added to a consistency group cannot be modified.

Procedure

1. Choose Data Protection > Block Protection > Remote Replication Pair.
2. Click More on the right of the desired remote replication pair and select Modfiy.

   The Modify Remote Replication Pair page is displayed on the right.

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

   Table 1 Remote replication pair parameters

   Parameter	Description
   Speed	Indicates the data synchronization speed of the remote replication pair. 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 sync begins: The system starts timing as soon as the latest synchronization begins. After the time specified in Interval is reached, the system automatically starts data synchronization between primary and secondary resources again. NOTE: If the last synchronization has not finished after the time specified in Interval is reached, the system performs the next synchronization after the last 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	Specific 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.
