comment |
string |
A comment available for use by the administrator. Valid in POST and PATCH. |
connectivity_tracking |
An overview of the connections to ONTAP by the initiators in this group.
|
|
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 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 |
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 |
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 |
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 |
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 |
|
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 |
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 |
svm |
SVM, applies only to SVM-scoped objects. |
|
target |
Properties of the SCSI target to which the initiator group provides access. |
|
uuid |
string |
The unique identifier of the initiator group. |

error
Information about asynchronous errors encountered while replicating this igroup. Igroups within a peering relationship are replicated in the same stream, so the error reported here might be related to this igroup or a prior replicated igroup that is now blocking the replication of this igroup. Both the error information and the igroup encountering the error are reported. If the error is configuration related, it can be corrected on the referenced igroup. The replication is retried using exponential backoff up to a maximum of one retry every 5 minutes. Every operation on the same stream triggers an immediate retry and restarts the exponential backoff starting with a 1 second delay. If the error is system related, the retries should correct the error when the system enters a healthy state.
