LUNs window

You can use the LUNs window to create and manage LUNs and to display information about LUNs. You can also add, edit, or delete initiator groups and initiator IDs.

LUN Management tab

This tab enables you to create, clone, delete, move, or edit the settings of LUNs. You can also assign LUNs to a Storage Quality of Service (QoS) policy group.

Command buttons

Create
Opens the Create LUN wizard, which enables you to create LUNs.

In a cluster on an AFF platform that does not contain any existing LUNs, the Create FC SAN optimized LUNs dialog box is opened, which enables you to set up one or more FC SAN optimized LUNs.

Clone
Opens the Clone LUN dialog box, which enables you to clone the selected LUNs.
Edit
Opens the Edit LUN dialog box, which enables you to edit the settings of the selected LUN.
Delete
Deletes the selected LUN.
Status
Enables you to change the status of the selected LUN to either Online or Offline.
Move
Opens the Move LUN dialog box, which enables you to move the selected LUN to a new volume or an existing volume or qtree within the same storage virtual machine (SVM).
Storage QoS
Opens the Quality of Service details dialog box, which enables you to assign one or more LUNs to a new or existing policy group.
Refresh
Updates the information in the window.

LUNs list

Name
Displays the name of the LUN.
SVM
Displays the name of the storage virtual machine (SVM) in which the LUN is created.
Container Path
Displays the name of the file system (volume or qtree) that contains the LUN.
Space Reservation
Specifies whether space reservation is enabled or disabled.
Available Size
Displays the space available in the LUN.
Total Size
Displays the total space in the LUN.
%Used
Displays the total space (in percentage) that is used.
Type
Specifies the LUN type.
Status
Specifies the status of the LUN.
Policy Group
Displays the name of the Storage QoS policy group to which the LUN is assigned. By default, this column is hidden.
Application
Displays the name of the application that is assigned to the LUN.

Details area

The area below the LUNs list displays details related to the selected LUN.

Details tab
Displays details related to the LUN such as the LUN serial number, whether the LUN is a clone, LUN description, the policy group to which the LUN is assigned, minimum throughput of the policy group, maximum throughput of the policy group, details about the LUN move operation, and the application assigned to the LUN. You can also view details about the initiator groups and initiators that are associated with the selected LUN.
Performance tab
Displays performance metrics graphs of the LUNs, including data rate, IOPS, and response time.

Changing the client time zone or the cluster time zone impacts the performance metrics graphs. Refresh your browser to see the updated graphs.

Initiator Groups tab

This tab enables you to create, delete, or edit the settings of initiator groups and initiator IDs.

Command buttons

Create
Opens the Create Initiator Group dialog box, which enables you to create initiator groups to control host access to specific LUNs.
Edit
Opens the Edit Initiator Group dialog box, which enables you to edit the settings of the selected initiator group.
Delete
Deletes the selected initiator group.
Refresh
Updates the information in the window.

Initiator Groups list

Name
Displays the name of the initiator group.
Type
Specifies the type of protocol supported by the initiator group. The supported protocols are iSCSI, FC/FCoE, or Mixed (iSCSI and FC/FCoE).
Operating System
Specifies the operating system for the initiator group.
Portset
Displays the port set that is associated with the initiator group.
Initiator Count
Displays the number of initiators added to the initiator group.

Details area

The area below the Initiator Groups list displays details about the initiators that are added to the selected initiator group and the LUNs that are mapped to the initiator group.

Portsets tab

This tab enables you to create, delete, or edit the settings of port sets.

Command buttons

Create
Opens the Create Portset dialog box, which enables you to create port sets to limit access to your LUNs.
Edit
Opens the Edit Portset dialog box, which enables you to select the network interfaces that you want to associate with the port set.
Delete
