Creating a Volume

The storage space of a newly created storage pool cannot be identified by a host. The host can use the storage space only after the storage space of the storage pool is divided into volumes and the volumes are mapped to the host.

Procedure

  1. Choose Services > Block Service > Volume.
  2. Click Create.

    The Create Volume page is displayed.

  3. Set parameters for the volume.

    Table 1 describes related 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 a volume.

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