Viewing LUN Information

Viewing LUN Information

This operation enables you to view the information about all the LUNs on a storage system.


At least one LUN has been created.


  1. Choose Provisioning > LUN.
  2. View information about the LUNs in the list.

    Table 5-9 describes the related parameters.
    Table 5-9 LUN parameters





    Name of a LUN.




    ID of a LUN.



    Health Status

    Health status of a LUN.



    Running Status

    Running status of a LUN.



    Use Type

    Use type of a LUN. The use types include:

    • Internal: common LUN created on a local storage device.
    • External: eDevLUN created for taking over a remote LUN.
    • PE LUN: a LUN created for a VVol LUN in VMware software defined storage only. PE LUNs function as I/O demultiplexers to simplify the connection between VMs and VVol LUNs. VM I/Os are sent to the corresponding VVol LUN through a PE LUN.
    • NAS LUN: A LUN used by a Dorado NAS unit.
      • This parameter applies to V300R002C10 and later versions.
      • Some device models do not support NAS LUN. For details about device models that support this feature, see the product description specific to your product model.
    • VVol LUN: provides storage space for VMware VMs.




    Capacity of a LUN.


    1.000 GB


    Number of the sectors in a LUN.



    Allocated Capacity

    Capacity allocated to a LUN. The capacity includes the data capacity and metadata capacity, but does not include the data protection capacity.


    1.187 GB

    Owning Storage Pool

    Storage pool to which a LUN belongs.




    Mapping status of a LUN, indicating whether a LUN is mapped to a host or not.



    Data Protection

    Data protection method of a LUN.


    Application Type

    Type of service on a LUN.




    WWN of a LUN.



    Remote WWN

    WWN of a remote LUN.


    Takeover LUN WWN

    WWN of the eDevLUN after takeover.


    Owning Controller

    Controller that owns the LUN.



    Masquerading Status

    Masquerading status can be:

    • No Masquerading
    • Inherited Masquerading

      Applies to local LUNs, used for inheriting remote LUN information such as the VID, PID, and SCSI protocol version.

    • Basic Masquerading

      Applies to eDevLUNs, used for replacing the basic LUN information such as the VID, PID, and LUN WWN.

    • Extended Masquerading

      Applies to eDevLUNs, used for replacing the basic LUN information and extended LUN information such as the SCSI protocol version, owning controller, and working controller.

    • Third-party

      Applies to eDevLUNs, used for taking over heterogeneous storage systems from third-party vendors online. (Some product models may not support this type.)


    No Masquerading

    Working Controller

    Working controller of a LUN, which is the only controller that processes read/write requests on the LUN. If hosts send I/Os to a non-working controller, the I/Os are forwarded to the working controller for processing.



    Data Protection Capacity

    Capacity of data protected in a LUN.


    For example, if snapshots are created for LUNs, the storage space occupied by these snapshots after they are activated is the data protection capacity.


    1.024 MB


    Indicates whether a LUN is a clone LUN.
