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 on the storage system.


  1. Log in to DeviceManager.
  2. Choose Provisioning > LUN.
  3. View information about the LUNs in the list.


    GUIs may vary with product versions and models. The actual GUIs prevail.

    Table 6-8 LUN parameters





    Name of a LUN.




    ID of a LUN.



    Health Status

    Health status of a LUN.



    Running Status

    Running status of a LUN.




    Type of a LUN. The types include:

    • Thick LUN
    • Thin LUN


    Thick LUN

    Use Type

    Use type of a LUN. The use types include:

    • Internal: common LUN created in 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.
    • VVol LUN: provides storage space for VMware VMs.




    Description of a LUN.




    Capacity of a LUN, which is specified by a user during LUN creation.


    1.000 GB


    Number of the sectors in a LUN.



    Capacity Allocated

    Capacity allocated to a LUN. The capacity includes the data capacity and metadata capacity, but does not include the data protection capacity. The metadata capacity is about 1% of the data capacity and 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.




    WWN of a LUN.



    Remote WWN

    WWN of a remote LUN.


    Takeover LUN WWN

    WWN of the eDevLUN after takeover.


    SmartTier Policy

    Data migration policies, including:

    • Automatic relocation

      This policy automatically relocates data blocks based on their activity levels. Automatic relocation relies on the analysis result from I/O monitoring. Thus I/O monitoring must be enabled and the service monitoring period must be set before automatic relocation.

    • Relocation to high-performance tier

      This policy is recommended for the applications (such as OLTP databases) sensitive to the response time, IOPS, and bandwidth. This policy preferentially promotes data blocks to the high-performance tier and the performance tier. If the capacity of the data blocks to be relocated is larger than the capacity of the high-performance tier (or performance tier), only data blocks with the most activities are promoted to the high performance tier (or the performance tier).

    • Relocation to low-performance tier

      This policy is recommended for applications (such as file sharing) insensitive to performance. This policy preferentially demotes data blocks to the performance tier and the capacity tier, regardless of the activity levels of these data blocks.

    • No relocation

      This policy does not relocate data blocks among storage tiers, and data can be relocated only when the data relocation policy is changed.


    This parameter is not supported by some product versions or models. The actual GUIs prevail.


    Automatic relocation

    Masquerading Status

    Masquerading status can be:

    • No Masquerading
    • 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.

    • Inherited Masquerading

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

    • Third-party

      Applies to eDevLUNs, used for taking over heterogeneous storage systems from third-party vendors online.


    No Masquerading

    vStore Name

    Name of the vStore to which the LUN belongs.



    vStore ID

    ID of the vStore to which the LUN belongs.
