igroup-create | [top]

> Creates a new initiator group. In Data ONTAP 7.3 and later, the ALUA (Asymmetiric Logical Unit Access) attribute will be enabled by default if initiator-group-type is "fcp" and os-type is "aix", "hpux", or "linux. In Data ONTAP Cluster-Mode 8.1 and later, the ALUA attribute is enabled by default on all initiator groups.

> Input Name | Range | Type | Description
> bind-portset |  | string optional | Name of a current portset to bind to the newly created igroup.
> initiator-group-name |  | string | Name of initiator group.
> initiator-group-type |  | string | Type of the initiator group. Possible values: "fcp", "iscsi", "mixed". "mixed" is available in Data ONTAP Cluster-Mode 8.1 or later only.
> os-type |  | initiator-group-os-type optional | OS type of the initiators within the group. The default value if not specified is "default". The os type applies to all initiators within the group and governs the finer details of SCSI protocol interaction with these initiators. It is strongly recommended for the caller of this API to specify an OS type that is not "default". Some host OSes require this type field be set correctly in order to function properly.

> Yes

igroup-destroy | [top]

> Destroys an existing initiator group. By default a group cannot be destroyed if there are existing lun maps defined for that group. This behaviour can be overridden with the use of force option set to "true" which will destroy the initiator group and any associated lun maps.

> Input Name | Range | Type | Description
> force |  | boolean optional | Forcibly destroy the initiator group, even if there are existing lun maps. Best practice is to attempt to unmap all the luns associated with a group before destroying it.
> initiator-group-name |  | string | Name of initiator group.

> Errno | Description
> EVDISK_ERROR_NO_SUCH_INITGROUP |  |
> EVDISK_ERROR_INITGROUP_MAPS_EXIST |  |

> Input Name | Range | Type | Description

igroup-set-attribute | [top]

> Sets an attribute for an initiator group.

> attribute |  | string | Name of the attribute to change. Possible values: "alua", "os-type", "throttle_borrow", "throttle_reserve", "report_scsi_name". "alua" is available in Data ONTAP 7.2 or later. "report_scsi_name" is available in Data ONTAP 8.1.0 or later. "throttle_reserve","throttle_borrow" and "report_scsi_name" are not available in Data ONTAP Cluster-Mode.
> force |  | boolean optional | If the requested attribute is "os-type", forcibly set the attribute, disabling conflict checks with the high-availability partner where and when applicable. If not specified all conflict checks are performed. This field is ignored in Data ONTAP Cluster-Mode or if the requested attribute is not "os-type".
> initiator-group-name |  | string | Name of initiator group.
> value |  | string | Value for the attribute. The valid values for "os-type" are the supported os-types listed in the igroup-create API. In Data ONTAP 7-Mode, setting the "os-type" attribute will perform checks with the high-availability partner if this filer is running in the 'single_image' fcp cfmode and this igroup is an FCP igroup. The optional force argument can be used to override these checks if the high-availability partner can not be reached. It is also strongly recommended the "default" os-type not be used. Using "default" may cause problems with LUN access. API to always require the proper OS type information The valid values for "throttle_reserve" are 0-99 The valid values for "throttle_borrow" are true or false The valid values for "alua" are true or false The valid values for "report_scsi_name" are true or false
