Creating a Volume

The storage space of a newly created storage pool cannot be identified by an application server. An application server can use the storage space of a storage pool only after the storage space is logically divided into multiple volumes and the volumes are mapped to hosts or host groups.

Procedure

  1. Choose Resources > Resources > Volume.
  2. Click Create.

    The Create Volume page is displayed.

  3. Set parameters for the volume.

    Table 1 describes related parameters.

    Table 1 Volume parameters

    Parameter

    Description

    Name

    Indicates the name of a volume to be created.

    NOTE:
    • The name must be unique.
    • The name can contain letters, digits, underscores (_), and hyphens (-).
    • The name contains 1 to 95 characters.

    Capacity

    Indicates the size of a volume.

    NOTE:

    Storage system capacity equation: 1 PB = 1,024 TB, 1 TB = 1,024 GB, 1 GB = 1,024 MB, 1 MB = 1,024 KB, 1 KB = 1,024 bytes.

    Quantity

    Indicates the number of created volumes.

    NOTE:
    • The value ranges from 1 to 1000.
    • The capacities of volumes created in a batch are the same.

    Start No.

    Indicates the start number of created volumes.

    NOTE:
    • This parameter is mandatory when the number of created volumes is greater than 1. From the specified start number, the system incrementally appends a suffix number to the name of each volume for volume distinction.
    • The value of the start number ranges from 0 to (10,000 – Number of volumes created in the batch). For example, if you want to create 300 volumes in a batch, the value range of the start number is 0 to 9700.

    Storage Pool

    Indicates the storage pool to which a volume belongs.

    NOTE:

    You can click Create to create a storage pool.

    QoS policy

    Indicates the QoS policy of the volume.

    NOTE:

    To set a QoS policy for a volume, choose Resources > Tuning > SmartQoS and create a QoS policy first. For details, see Creating a SmartQoS Policy.

  4. Click OK.
  5. Confirm your operation as prompted.
