igroup

An initiator group (igroup) is a collection of Fibre Channel (FC) world wide port names (WWPN), and/or iSCSI Qualified Names (IQNs), and/or iSCSI EUIs (Extended Unique Identifiers) that identify host initiators.

Initiator groups are used to control which hosts can access specific LUNs. To grant access to a LUN from one or more hosts, create an initiator group containing the hosts' initiator names, then create a LUN map that associates the initiator group with the LUN.

An initiator can appear in multiple initiator groups. An initiator group can be mapped to multiple LUNs. A specific initiator can be mapped to a specific LUN only once.

All initiators in an initiator group must be from the same operating system. The initiator group's operating system is specified when the initiator group is created.

When an initiator group is created, the protocol property is used to restrict member initiators to Fibre Channel (fcp), iSCSI (iscsi), or both (mixed).

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.

Name Type Description

_links

_links

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.

initiators

array[igroup_initiator_no_records]

The initiators that are members of the group. Optional in POST.

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 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.

Note that renaming an initiator group must be done in a PATCH request separate from any other modifications.

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.

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.

svm

svm

uuid

string

The unique identifier of the initiator group.
