Adding the Bunker RVG to the RDS

This section guides you through the process of creating the Bunker RVG, establishing the required RLINKs and starting replication using the Add Bunker option. You can also do this using the vxrds addBunker command.

Note:

Adding the Bunker RVG fails if the Replicator Log sizes differ. The Bunker Replicator Log must be of the same size and the same name as the Primary Replicator Log.

You can either choose to create the RVG on the Bunker node through the Add Bunker wizard or using the command line options.

To create and add a Bunker RVG to an RDS

  1. Click on the required RDS under the Replication Network node and select the Add Bunker option from the RDS right-click menu.
  2. Read the information on the Welcome panel of the Add Bunker wizard and click Next.

    Complete the Specify Bunker Host for Replication panel as follows:

    Bunker Host

    Specify the name or IP of the Bunker host in the provided field. Even if the storage on the Bunker host is directly accessible to the Primary, you must still provide the name of the host that you may plan to use if a disaster occurs.

    Add Bunker with Storage protocol

    Select this check box only if the storage on the Bunker node is directly accessible from the Primary, that is, the storage is shared between the Primary and Bunker Secondary. Make sure that the disk group which you plan to use for creating the Bunker RVG is imported on the Primary node.

    You can then use the Storage protocol to replicate to the Bunker node across Fibre Channel (FC) or iSCSI.

    Bunker Diskgroup

    This option is enabled for selection only if you have selected the Add Bunker with STORAGE protocol. In this case you can choose to have a different disk group name for the Bunker RVG. Otherwise, the same disk group name as on the Primary is used.

    Click Next. If the specified host is not connected to VEA, the wizard tries to connect it when you click Next. When prompted, enter the connection information in the provided fields. Wait till the connection process is complete and then click Next again.

  3. If the disk group with the required Replicator Log volume as on the Primary host does not exist on the Bunker Secondary, you can create the disk group and the required volumes through the Create Dynamic Disk Group on Secondary host panel. If the Dynamic Disk group that is the same as that on the Primary has already been created on the Bunker Secondary, then this panel does not appear.

    Complete the Create Dynamic Disk Group on Bunker host panel as follows:

    Create cluster group

    Choose this option only if you need to create a clustered disk group. Select the required disks from the Available disks pane. Either double-click on it or use the Add option to move the disks into the Selected disks pane. To select all the available disks, use the Add All option.

    Create Dynamic Disk Group

    Click Create Dynamic Disk Group to proceed with creating the disk group. A disk group with the same name as that on the Primary is created.

    After the disk group has been created, click Next.

  4. The Volume Information on connected hosts panel appears. This panel displays information about the availability of Replicator Log volume on the Bunker Secondary node.

    This panel does not appear if the required Replicator Log volume that is the same as that on the Primary is available on the Bunker Secondary host.

    • Because the Replicator Log volume is not created, the Create Volume option is enabled. Click this option to create the required Replicator Log volume on the Bunker Secondary.

    • The Create Volume dialog automatically displays the Replicator Log volume name and the size after verifying the information about the Primary host.

      Complete the information on this panel as follows:

      Name

      Displays the name for the volume in the Name field. This is the same as that specified for the Primary volume.

      Size

      Displays the size of the volume in the Size field. This is the same as that specified for the Primary volume.

      Layout

      Specify the volume layout. Select the appropriate volume layout depending on your requirement.

      Disks Selection

      Enables you to specify the disk selection method.

      Select the Select disks automatically option if you want Volume Replicator to select the disks.

      Select the Select disks manually option to use specific disks from the Available disks pane for creating the volume. Either double-click on it or select Add to move the disks into the Selected disks pane.

      After verifying the information, click OK to create the required volume. You are taken back to the Volume Information on connected hosts panel.

    • After the Replicator Log volume has been created, the volume information panel is updated to display the Replicator Log volume on the Primary and Bunker Secondary host. Click Next.

  5. Complete the Edit replication settings panel to specify the basic and advanced replication settings. The required settings are exactly similar to the Edit replication settings panel on the RDS wizard.

    For details,

  6. Choose the appropriate option from the Start Replication panel as described below.

    To add the Bunker Secondary and start replication immediately, check Start Replication with the following options:

    Synchronize Automatically

    For an initial setup, use this default option to synchronize the Bunker Secondary and start replication.

    If you add the Bunker RVG to a setup that already has Secondary hosts, then this option checks for the position of Secondary that lags behind the most and updates the Bunker RVG, appropriately.

    Synchronize from Checkpoint

    This option is not supported for a Bunker RVG.

    • To add the Bunker Secondary without starting replication clear the Start Replication option. You can start replication later by using the Start Replication option from the Secondary RVG right-click menu. Click Next to display the Summary panel.

    • Review the information on the Summary panel. Click Back to change any information you had specified or click Finish to add the Bunker Secondary to the RDS and exit the wizard.
