  • lun igroup bind

  • lun igroup unbind

Parameters

Name Type In Required Description

uuid

string

path

True

The unique identifier of the initiator group.

Request Body

Name Type Description

_links

_links

comment

string

A comment available for use by the administrator. Valid in POST and PATCH.

connectivity_tracking

connectivity_tracking

An overview of the connections to ONTAP by the initiators in this group.

  • readOnly: 1

  • Introduced in: 9.11

delete_on_unmap

boolean

An option that causes the initiator group to be deleted when the last LUN map associated with it is deleted. Optional in POST and PATCH. This property defaults to false when the initiator group is created.

igroups

array[igroup_child]

The initiator groups that are members of the group. Optional in POST.

This property is mutually exclusive with the initiators property during POST.

This array contains only the direct children of the initiator group. If the member initiator groups have further nested initiator groups, those are reported in the igroups property of the child initiator group.

Zero or more nested initiator groups can be supplied when the initiator group is created. The initiator group will act as if it contains the aggregatation of all initiators in any nested initiator groups.

After creation, nested initiator groups can be added or removed from the initiator group using the /protocols/san/igroups/{igroup.uuid}/igroups endpoint. See link:post-protocols-san-igroups-igroups(#-san-igroup-nested-create)anddelete-protocols-san-igroups-igroups-.htmlPOST /protocols/san/igroups/{igroup.uuid}/igroups and [DELETE /protocols/san/igroups/{igroup.uuid}/igroups/{uuid}] for more details.

initiators

array[initiators]

The initiators that are members of the group or any group nested below this group. Optional in POST.

This property is mutually exclusive with the igroups property during POST.

During GET, this array contains initiators that are members of this group or any nested initiator groups below this group. When initiators of nested groups are returned, they include links to the initiator group that directly contains the initiator.

Zero or more initiators can be supplied when the initiator group is created. After creation, initiators can be added or removed from the initiator group using the /protocols/san/igroups/{igroup.uuid}/initiators endpoint. See link:post-protocols-san-igroups-initiators(#-san-igroup-initiator-create)anddelete-protocols-san-igroups-initiators-.htmlPOST /protocols/san/igroups/{igroup.uuid}/initiators and [DELETE /protocols/san/igroups/{igroup.uuid}/initiators/{name}] for more details.

lun_maps

array[lun_maps]

All LUN maps with which the initiator is associated.

If the requested igroup is part of a remote, non-local, MetroCluster SVM, the LUN maps are not retrieved.

There is an added computational cost to retrieving property values for lun_maps. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter. See Requesting specific fields to learn more.

name

string

The name of the initiator group. Required in POST; optional in PATCH.

os_type

string

The host operating system of the initiator group. All initiators in the group should be hosts of the same operating system. Required in POST; optional in PATCH.

parent_igroups

array[igroup_parent]

The initiator groups that contain this initiator group as a member.

portset

portset

The portset to which the initiator group is bound. Binding the initiator group to a portset restricts the initiators of the group to accessing mapped LUNs only through network interfaces in the portset.

In a nested initiator group hierarchy, only a portset bound to the initiator group at the same level at which it is mapped, applies; portsets bound to parent or child initiator groups are ignored.

Optional in POST and PATCH. To unbind a portset from the initiator group, PATCH the portset object to null, or PATCH portset.name to an empty string ("").

protocol

string

The protocols supported by the initiator group. This restricts the type of initiators that can be added to the initiator group. Optional in POST; if not supplied, this defaults to mixed.

The protocol of an initiator group cannot be changed after creation of the group.

replication

replication

Properties related to initator group replication.

supports_igroups

boolean

An initiator group may contain either initiators or other initiator groups, but not both simultaneously. This property is true when initiator groups can be added to this initiator group. The initiators.name property cannot be used to determine this via a query because it reports initiators inherited from nested igroups.

svm

svm

SVM, applies only to SVM-scoped objects.

target

target

Properties of the SCSI target to which the initiator group provides access.

uuid

string

The unique identifier of the initiator group.
