igroup

igroup

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

logical_unit_number

integer

The logical unit number assigned to the LUN when mapped to the specified initiator group. The number is used to identify the LUN to initiators in the initiator group when communicating through Fibre Channel Protocol or iSCSI. Optional in POST; if no value is provided, ONTAP assigns the lowest available value.

  • example: 1

  • Max value: 4095

  • Min value: 0

  • x-nullable: true

lun

lun

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.
