You can configure the primary and secondary sites to complete the high availability configuration.

  1. In the Configure Primary Site window, connect ports in the primary storage system to the server in the primary site and to the server in the secondary site, if there is one. You can configure preferred and unpreferred paths.

    Create, attach and protect volumes with high availability-configure primary site

  2. You can view servers and their WWNs, along with ports on the storage system. Ops Center Administrator scan for existing host groups on the storage array and try to reuse them by default.
    For VSP 5000 series storage systems, you can click a port to display a list of ports with their DKC locations, CTL locations, and redundancy levels.


    The following options are available for managing LUN paths:
    • If you connect more than one server to the same port, the Share a host group with all servers box displays. Select the box to add the servers to a single host group.
    • Note: If host groups already exists on that port and single host group cannot be created, the check box will not appear.
      Existing paths are populated as follows: all existing host groups with one or more server WWN and the exact same host mode and host mode options selected on the Attach Settings window are populated as paths.

      To prevent the volume from being added to an existing path, click the path to highlight it, then click Delete Selected.

    • Click Suggest to populate automatically selected paths. By default, the least-used ports are selected. Suggest paths need both server and storage ports be logged into the fabric switches in the Ops Center Administrator inventory.
      Note: For VSP 5000 series storage systems, the first port suggested has the fewest LUN definitions and the second port suggested has the second fewest LUN definitions.
    • To manually create a path, click a WWN and a port to connect them with a blue connector line. Click the connector again and then click Delete Selected to delete the connection.
    • Optionally, you can click Switch View to use tables to create paths by selecting Server Ports to attach to Storage Ports.
  3. Click Next to configure ports in the secondary storage system to the server in the primary site, and to the server is the secondary site, if there is one.
  4. Click Next to continue to the optional Operation Plan step, you can confirm settings specified in each window and can confirm the resources to be used in the job, including LUN candidates.
    Note: Internet Explorer 11 does not support the Operation Plan page. Use another supported brower to access this feature.
  5. You can specify the LUN range for volumes in the LUN Settings pop up window which is launched by clicking LUN Settings button above the Planned Path Configuration table.
  6. You can make it mandatory to use the LUNs displayed in the table by specifying Yes to Mandate Using Displayed LUN.
    Note: Please note that if Yes is specified to use displayed LUNs, primary and secondary volumes' LUNs may not be aligned even though Mandate LUN Alignment is set to Yes.
  7. When you are satisfied with all the settings, click Submit.
  8. Click Submit to create a job to create volumes, attach to servers and set up data protection.
  9. You can monitor the job in the Jobs page.
    Note: If the job does not complete successfully, access Ops Center Protector to remove the related resources (Block Host Node, Policy, and Data Flow) with the same name as the selected Replication Group.

    When using an existing Replication group, remove added P-Vol from Block Host Node.

    To edit a Block Host Node created by Ops Center Administrator in Ops Center Protector, specify LDEV IDs in decimal format per line and not in hex format or range format.
