To manage your initiator groups (igroups), you can perform a range of tasks, including creating igroups, destroying them, and renaming them.
What igroups are
Initiator groups (igroups) are tables of FC protocol host WWPNs or iSCSI host node names. You can define igroups and map them to LUNs to control which initiators have access to LUNs.
Initiator groups, or igroups, are tables of host identifiers such as Fibre Channel WWPNs and iSCSI node names. You can use igroups to control which hosts can access specific LUNs.
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.
When deleting igroups, you can use a single command to simultaneously remove the LUN mapping and delete the igroup. You can also use two separate commands to unmap the LUNs and delete the igroup.
