Retrieve an initiator

Contributors

GET /protocols/san/igroups/{igroup.uuid}/initiators/{name}

Introduced In: 9.6

Retrieves an initiator of an initiator group.

This API only reports initiators owned directly by the initiator group. Initiators of nested initiator groups are not part of this collection.

Expensive properties

There is an added computational cost to retrieving values for these properties. They are not included by default in GET results and must be explicitly requested using the fields query parameter. See Requesting specific fields to learn more.

Response

Status: 200, Ok
Name Type Description

_links

connectivity_tracking

connectivity_tracking

Overview of the initiator's connections to ONTAP.

  • readOnly: 1

  • Introduced in: 9.11

igroup

igroup

The initiator group in which the initiator is found.

Note that this does not mean that the initiator cannot also be found in other initiator groups.

name

string

The FC WWPN, iSCSI IQN, or iSCSI EUI that identifies the host initiator. Valid in POST only and not allowed when the records property is used.

An FC WWPN consists of 16 hexadecimal digits grouped as 8 pairs separated by colons. The format for an iSCSI IQN is iqn.yyyy-mm.reverse_domain_name:any. The iSCSI EUI format consists of the eui. prefix followed by 16 hexadecimal characters.

proximity

proximity

Properties that define to what SVMs the initiator is proximal. This information is used to properly report active optimized and active non-optimized network paths via ALUA. If no configuration has been specified for an initiator, the sub-object will not be present in GET.

These properties can be set via initiator group POST and PATCH and apply to all instances of the initiator in all initiator groups in the SVM and its peers. The proximity sub-object for an initiator is set in POST and PATCH in its entirety and replaces any previously set proximity for the initiator within the SVM for the initiator within the SVM. The local_svm property must always be set to true or false when setting the proximity property. To clear any previously set proximity, POST or PATCH the proximity object to null.

records

array[records]

An array of initiators specified to add multiple initiators to an initiator group in a single API call. Not allowed when the name property is used.
