Modifying a Remote Replication Pair

Modifying a Remote Replication Pair

Scenario

This operation enables you to change the synchronization type and speed, and restoration policy of a remote replication pair.

Prerequisites

  • You have created a remote replication pair.
  • You have not associated the remote replication pair with a consistency group.

Procedure

    1. In FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster. On the Disaster Recovery Service page, at the row where the cluster resides, click Manage Remote Replication, and select Remote Replication Pair Management.

      The Remote Replication Pair Management page is displayed.

    2. Modify the restoration policy or synchronization speed.

      1. At the row where the remote replication pair to be modified resides, click , and modify related parameters.
      2. Table 3-6 lists related parameters.
        Table 3-6  Remote replication parameters

        Parameter

        Description

        Value (Example)

        Restoration Policy

        A restoration policy determines whether the system automatically synchronizes data after the fault is rectified.
        • Automatic: The system automatically synchronizes data.
        • Manual: Data synchronization must be performed manually.

        Automatic

        Synchronization Speed

        Data copy rate in KB/s. Value range: [1024,1048576]. System default value: 32768.

        32768

      3. Modify Restoration Policy and Synchronization Speed as prompted.

    3. Modify Synchronization Type

      1. In the operation column of the remote replication pair to be modified, choose More > Change Synchronization Type.
      2. On the Change Synchronization Type page, select a synchronization type to be modified from the drop-down list box, and click Confirm.

        Parameter description:

        • Manual: You need to manually start data synchronization.
        • Timed wait when synchronization starts: Period from the time a synchronization starts to the time the next synchronization starts. If this period is shorter than the synchronization time, complete the current synchronization before starting the next one.
        • Timed wait when synchronization ends: Period from the time a synchronization ends to the time the next synchronization starts.
        • Specify the time policy: Synchronization starts at a defined time point.
          • Daily: Synchronization starts at a defined time point every day.
          • Hourly: Synchronization starts at a defined time point every hour.
      3. Modify Synchronization Type as prompted.
