Configuring iSCSI protocol on SVMs

You can configure the iSCSI protocol on the Storage Virtual Machine (SVM) to provide block-level data access by using System Manager. You can create iSCSI LIFs and portsets and add the LIFs to the portsets. LIFs are created on the most suitable adapters and assigned to portsets to ensure data path redundancy.

Before you begin

About this task

You can configure the iSCSI protocol while creating the SVM or you can do so at a later time.


  1. If you have not configured the iSCSI protocol while creating the SVM and if the FCP service is not started, expand the Storage Virtual Machines hierarchy, select the SVM in the navigation pane, and click iSCSI.
  2. Optional: In the Data Interface Configuration section, specify an alias for the iSCSI target.
    The maximum number of characters for an alias name is 128. If you do not specify a target alias, the SVM name is used as an alias.
  3. Specify the number of iSCSI LIFs that can be assigned to a single node.
    The minimum number of LIFs per node is one. The maximum number is the minimum of all the ports in the up state across the nodes. If the maximum value is an odd number, the previous even number is considered as the maximum value. You can choose any even number in the minimum and maximum value range.
    A 4-node cluster has node1, node2, and node3 with 6 ports each in the up state, and node4 with 7 ports in the up state. The effective maximum value for the cluster is 6.
    If the number of LIFs that you want to assign to the node is more than 2, you must assign at least one portset to each LIF.
  4. Specify the network details, including the subnet details, to create iSCSI LIFs by choosing one of the following:
    • Select the subnet from which the IP address will be assigned automatically to the interface.
    • Select Use this as the starting IP Address and type the IP address.
    The IP address you specify will be added to the subnet if it is not already present in the subnet range.
  5. Optional: Provision a LUN for iSCSI storage when configuring the iSCSI protocol by providing the LUN size, OS type for the LUN, and host initiator details.
  6. If you want to verify or modify the automatically generated iSCSI LIFs configuration, select Review or Modify LIFs configuration (Advanced Settings).
    You can modify only the LIF name and the home port. By default, the portsets are set to the minimum value. You must ensure that you specify unique entries. If you specify duplicate LIF names, System Manager appends numeric values to the duplicate LIF name.

    Based on the selected portset, the LIFs are distributed across the portsets using a round-robin method to ensure redundancy in case of node or port failure.

  7. Click Submit & Continue.


The iSCSI LIFs and portsets are created with the specified configuration. The LIFs are distributed accordingly among the portsets. The iSCSI service is started if all the LIFs are successfully created.

If the LIF creation fails, you can use the Network Interfaces window to create the LIFs, attach the LIFs to the portsets by using the LUNs window, and start the iSCSI service by using the iSCSI window.
