Assigning LUNs to Storage QoS

About this task

•	You cannot assign Storage QoS to a LUN if the following storage objects are assigned to a policy group:

•	Parent volume of the LUN

•	Parent Storage Virtual Machine (SVM) of the LUN

•	You can assign Storage QoS or modify QoS details for a maximum of 10 LUNs at the same time.

Steps

1.	From the home page, double-click the appropriate storage system.

2.	Expand the Storage Virtual Machines hierarchy in the left navigation pane.

3.	In the navigation pane, select the SVM and click Storage > LUNs.

4.	In the LUN Management tab, select one or more LUNs for which you want to assign Storage QoS.

5.	Click Storage QoS.

6.	In the Quality of Service Details dialog box, select the Manage Storage Quality of Service check box if you want to manage the workload performance of the LUN.

7.	Create a new storage QoS policy group or select an existing policy group to control the input/output (I/O) performance of the LUN:

a.	Specify the policy group name.

b.	Specify the maximum throughput limit to ensure that the workload of the objects in the policy group do not exceed the specified throughput limit.

Select Existing Policy Group and click Choose to select an existing policy group from the Select Policy Group dialog box.

Note The Storage Objects Count column in the Select Policy Group dialog box is displayed only for storage systems running Data ONTAP 8.2.1 or later.

8.	Click the link that specifies the number of LUNs to review the list of selected LUNs, and click Discard if you want to remove any LUNs from the list.
