Viewing LUN Information

Prerequisites

At least one LUN has been created on the storage system.

Procedure

1. Log in to DeviceManager.
2. Choose Provisioning > LUN.
3. View information about the LUNs in the list.
   Table 5-7 describes related parameters.

   Table 5-7 LUN parameters

   Parameter	Description	Setting
   Name	Name of a LUN.	[Example] LUN001
   ID	ID of a LUN.	[Example] 1
   Health Status	Indicates whether a LUN is normal.	[Example] Normal
   Running Status	Running status of a LUN.	[Example] Online
   Type	Type of a LUN. The types include: Thick LUN Thin LUN	[Example] thick LUN
   Use Type	Use type of a LUN. Internal: common LUN created in a local storage device. External: eDevLUN created for taking over a LUN in a remote storage device. PE LUN: PE (Protocol Endpoint) LUN is used for VVol LUNs in VMware software defined storage only. PE is used as an I/O demultiplexer to simplify the connection between VMs and VVol LUNs. When there is a VM operation I/O, the I/O is sent to the corresponding VVol LUN through a PE LUN. VVol LUN: provides storage space for VMware VMs.	[Example] Internal
   Description	Description of a LUN.	[Example] -
   Capacity	Capacity of a LUN. A user specifies the capacity when creating a LUN.	[Example] 1.000 GB
   Sectors	Number of the sectors in a LUN.	[Example] 2097152
   Allocated Capacity	Storage pool capacity allocated to a LUN. The capacity includes the data capacity and metadata capacity of the LUN (excluding data protection capacity). The metadata capacity occupies about 1% of the LUN data capacity and LUN data protection capacity.	[Example] 1.187 GB
   Owning Storage Pool	Storage pool to which a LUN belongs.	[Example] StoragePool001
   Mapping	Mapping status of a LUN, indicating a LUN is mapped to a host or not.	[Example] Unmapped
   Data Protection	Data protection method of a LUN. The protection methods include: Snapshot Remote Replication Clone LUN Copy HyperMirror HyperMetro	[Example] Clone
   WWN	WWN of a LUN.	[Example] 60022a1100037eca45ae3b6100000019
   Remote WWN	WWN of a remote LUN.	[Example] -
   Takeover LUN WWN	WWN of the eDevLUN after takeover.	[Example] -
   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.	[Example] No Masquerading
