The host that accesses a logical volume using NVMe-oF is identified by a host NQN defined on the host instead of by a host bus adapter (HBA) WWN. Therefore, managing the HBA WWN is not required for verifying the security of host access to the logical volume.
Create a host group under the following conditions:
- If you want to control the host (HBA WWN) that permits the port to log in using the LUN security function of the port.
Use the zoning function of the fabric switch to manage the access restrictions between the storage target port and the HBA with the fabric connection. When the FC switch zoning is used for NVMe-oF, setting the host WWN is not required for the access restrictions.
- If you must set a host mode option to support a connected host and an HBA configuration.
