igroups can be configured for various settings such as ALUA and report_scsi_name. You can also configure throttles for your igroups to limit and control other parameters of the igroup.
You can enable ALUA for your igroups, as long as the host supports the ALUA standard.
You can enable report_scsi_name for your igroups to control reporting or hiding the new inquiry descriptor to the initiators.

Data ONTAP implements a mechanism called igroup throttles, which you can use to ensure that critical initiators are guaranteed access to the queue resources and that less-critical initiators are not flooding the queue resources.
