When using external migration, volumes must be virtualized before they can be migrated.

Perform the steps to attach volumes to storage and discover external storage.

  1. Navigate to External Volumes on the target storage system.
  2. Click the plus (+) sign to open the Create External Volumes window.
    A list of discovered volumes appears.
  3. Select the discovered volumes, then click Next.

  4. In the Volume Settings window, you can use Volume Settings to select a Volume ID / Range. Use the default selection Auto, to allow automatic selection of the volume. You can select either a Decimal or Hexadecimal range and enter the endpoints of the range. Click Next.
  5. You can confirm which Volume IDs will be used by clicking View Proposed Volume ID Selection.
    To mandate using volume IDs shown in pop-up dialog, select Yes under Mandate Using Displayed Volume ID.
    Note: The Mandate Using Displayed Volume ID selection will be reset to No if you move back to the previous step.
  6. Select servers to attach external volumes to be created, then click Next. To create external volumes without attaching to servers, click Next without selecting servers.

  7. You can view servers and their WWNs, along with ports on the storage system.

    create external volumes--select paths

    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.


    Port Redundancy level

    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 a single host group cannot be created, the check box does not appear.
    • To manually create a path, click WWNs to select them and then click a port to connect the two with a blue connector line. Click the connector again to delete the connection.
    • Optionally, click Switch View to use tables to create paths by selecting Server Ports to attach to Storage Ports.
  8. When the settings are complete, click Submit.
  1. After virtualization completes successfully, go to the server and locate and mount the newly attached external volume. This changes the I/O from the older volume(LUN) to the new LUN. This action is required before data can be migrated and will ensure that no data is lost in the process.
  2. Select volumes on the External Volumes window and migrate them.
