You can use System Manager to create LUNs for an existing aggregate, volume, or qtree when there is available free space. You can create a LUN in an existing volume or create a new FlexVol volume for the LUN. You can also enable storage Quality of Service (QoS) to manage the workload performance.
If you specify the LUN ID, System Manager checks the validity of the LUN ID before adding it. If you do not specify a LUN ID, ONTAP software automatically assigns one.
While selecting the LUN multiprotocol type, you should have considered the guidelines for using each type. The LUN Multiprotocol Type, or operating system type, determines the layout of data on the LUN, and the minimum and maximum sizes of the LUN. After the LUN is created, you cannot modify the LUN host operating system type.
In a MetroCluster configuration, System Manager displays only the following aggregates for creating FlexVol volumes for the LUN:
