LUNs window in System Manager - ONTAP 9.7 and earlier

06/14/2024 Contributors

You can use the LUNs window in ONTAP System Manager classic (available in ONTAP 9.7 and earlier) 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.

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
