Modifying Properties of a Remote Replication Pair

Procedure

1. Choose Data Protection > Protection Entity > Namespace > Remote Replication Pair.
2. Select the desired account from the Account drop-down list in the upper left corner.
3. Click More on the right of the desired remote replication pair and select Modify.

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

4. 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 10,240 MB/s (or 1024 KB/s to 10,485,760 KB/s). During initial synchronization, the recommended rate is 100 MB/s or higher. During incremental synchronization, if the service is busy, the recommended rate is 0 MB/s to 20 MB/s. During incremental synchronization, if the service load is heavy, the recommended rate is 20 MB/s to 70 MB/s. During incremental synchronization, if the service is idle, the recommended rate is 100 MB/s or higher. The default value is 32 MB/s.
   Recovery Policy	Determines how data is synchronized after an internal I/O error or a replication link fault is rectified. [Value range] Automatic: The system automatically synchronizes data. The pair enters the Synchronizing state. Manual: Data must be synchronized manually. The pair enters the To be recovered state.
   Sync Type	Determines how data is synchronized between primary and secondary resources. Possible values are: 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. Timed wait after sync ends: The system starts timing after the last synchronization finishes. After the time specified in Interval is reached, the system automatically starts data synchronization between primary and secondary resources again. Specific time policy: The system automatically synchronizes data between primary and secondary resources based on a specific time policy.
   Interval	Indicates the synchronization interval for Timed wait after sync begins and Timed wait after sync ends. [Value range] The interval is an integer ranging from 1 to 1440 when minutes is used as the unit. The value is an integer ranging from 30 to 59 when seconds is used as the unit. NOTE: This parameter is available only when Sync Type is set to Timed wait after sync begins or Timed wait after sync ends.
   Time Policy	Specific time policy: The system automatically synchronizes data between primary and secondary resources based on a specific time policy. [Value range] Weekly: Data synchronization begins at a specific time on a specific day. Its value ranges from 00:00 on Monday to 23:59 on Sunday. 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 Sync Type is set to Specific time policy.
