POST /protocols/san/igroups

Introduced In: 9.6

Creates an initiator group.

Required properties

  • svm.uuid or svm.name - Existing SVM in which to create the initiator group.

  • name - Name of the initiator group.

  • os_type - Operating system of the initiator group's initiators.

  • initiators.name - Name(s) of initiator group's initiators. This property can be used to create the initiator group and populate it with initiators in a single request.

Default property values

If not specified in POST, the following default property values are assigned.

  • protocol - mixed - Data protocol of the initiator group's initiators.

  • lun igroup create

  • Default value:

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.

Initiators and child initiator groups were both supplied, but only one option is allowed.

5374732

An initiator is already in another initiator group with a conflicting operating system type.

5374735

An attempt was made to add a child igroup that would exceed the maximum allowable depth.

5374737

A supplied child initiator group already exists in another initiator group's hierarchy.

5374739

A supplied child initiator group has an operating system type that differs from the parent initiator group.

5374740

A supplied child initiator group has an protocol that differs from the parent initiator group.

5374741

A supplied child initiator group is already owned by a different child in the initiator group's hierarchy.

5374742

A supplied child initiator group contains an initiator that is already owned by another initiator group in the hierarchy.

5374745

Initiator group cannot be added as a child to itself.

5374746

The cluster is currently running in a mixed version and nested initiator groups cannot be created until the effective cluster version reaches 9.9.1.

5374747

The cluster is currently running in a mixed version and initiator group comments cannot be created until the effective cluster version reaches 9.9.1.

5374758

An error was reported by the peer cluster while creating a replicated initiator group. The specific error will be included as a nested error.

5374878

The supplied child initiator group does not exist.

5374911

The supplied portset does not exist.

5374917

Duplicated initiators have conflicting property values.

5375055

The local_svm property of an initiator proximity was not specified.

5375056

An SVM peering relationship that does not have the initiator group's SVM as the local SVM was specified.

5375258

The igroup is already replicated to a different peer SVM.

5375261

Setting initiator proximity is not supported for the SVM type.

5376057

Setting initiator proximity is not supported for the ONTAP version.

5376059

Setting initiator proximity to a peer that is either the destination of an SVM DR relationship or in a Metrocluster configuration is not supported.

5376253

Initiator group replication requires an effective cluster version of 9.15.1.

5376255

Initiator group replication requires the peer cluster to have an effective cluster version of 9.15.1.

6620376

SVM peering information is unavailable.

6620384

The supplied SVMs are not peered.

26345672

The specified SVM peering relationship was not found.

26345673

An SVM peering relationship between the initiator group's SVM and specified peer SVM was not found.

26345675

An SVM peering relationship UUID and name were specified and they do not refer to the same SVM peering relationship.

26345680

Supplied SVM peer is on the local cluster. The operation requires a peer on a remote cluster.
