The LUN to which the initiator group is mapped. Required in POST by supplying either the lun.uuid, lun.name, or both.

reporting_nodes

array[reporting_nodes]

The cluster nodes from which network paths to the mapped LUNs are advertised via the SAN protocols as part of the Selective LUN Map (SLM) feature of ONTAP.

When a LUN map is created, the cluster node hosting the LUN and its high availability (HA) partner are set as the default reporting node. In POST, the property additional_reporting_node may be used to add an additional node and its HA partner.
