Create volumes and allocate them to compute nodes.

  • Required role: Storage or VpsStorage

  1. In the Compute Nodes window or the Compute Node detailed information window, allocate volumes to compute nodes by using one of the following methods:
    • In the Compute Nodes window, select the allocation-target compute nodes (1 to 100 nodes), click the preceding icon shown to the right of Select All, and then, from the menu that appears, select Create and Attach Volumes.

    • Change the view mode of the Compute Nodes window to Inventory view, click the preceding icon shown for each allocation-target compute node, and then, from the menu that appears, select Create and Attach Volumes.

    • In the Compute Node detailed information window for each allocation-target node, click the preceding icon, and then, from the menu that appears, select Create and Attach Volumes.

    The following dialog appears.

    (Bare metal) Compute port: FC connection or NVMe/TCP connection

    (Bare metal) Compute port: iSCSI connection

    (Cloud) Single-AZ configuration

    (Cloud) Multi-AZ configuration

  2. Enter each of the following parameters:
    • VIRTUAL PRIVATE STORAGE: Name of the VPS to which volume paths belong

      Only the VPS to which the compute node belongs is displayed.

    • (Cloud) RESOURCE TO MANAGE THE VOLUME: Resource that manages volumes

      This item is displayed when Multi-AZ configuration is applied. When creating a volume (journal volume or data volume) for remote copy, select a Storage Controller to manage the volume. In other cases, select Fault Domain for a primary to manage the volume.

    • (Cloud) PRIMARY FAULT DOMAIN: A fault domain to which the storage controller that manages the volume as a primary currently belongs
    • STORAGE NODE NAME (STORAGE CONTROLLER ID): ID of the storage controller that manages volumes. This item is displayed only when the compute port uses iSCSI connection.
    • CAPACITY SAVING: Setting of the data reduction function of volumes. This item is displayed only when "STORAGE NODE MINIMUM MEMORY SIZE" of the protection domain window is no less than 234 GiB and "WRITE BACK MODE WITH CACHE PROTECTION" of the storage cluster information is Enabled. If this item is not displayed, Disabled is set.
    • CAPACITY: Logical capacity of the volume and its unit
    • NUMBER OF VOLUMES: The number of volumes to be created
    • VOLUME NAME: The name of the volume
    • SUFFIX START NUMBER: The first sequential number suffixed to a volume name or nickname, in the case multiple volumes are created with the same volume name or nickname. If omitted, no number is added.
    • NUMBER OF DIGITS: The number of digits of a number suffixed to a name or nickname
    • VOLUME NICKNAME: The nickname of the volume. If omitted, VOLUME NAME is used.
    • START LUN: LUN start number

      You can specify this parameter in the case of iSCSI connection or FC connection.

      If you specify the LUN start number, unused LUN numbers are allocated in ascending order from the specified start number. If omitted, unused LUNs are allocated automatically in ascending order.

      Do not enter anything in the case of NVMe/TCP connection.

  3. Click Submit.
  4. When the following "Completed" message is displayed, processing is completed.
    • Successfully attached volumes to compute nodes.
