A host that uses the Non-Volatile Memory express (NVMe) protocol can contain only NMVe Qualified Names (NQNs). A host that uses the SCSI protocol cannot contain NQNs.
For a host that uses the NVMe protocol, use the -nvmenqn parameter to supply a list of NQNs to add to the host. For a host that uses the SCSI protocol, use the -fcwwpn, -iscsiname, or -saswwpn parameter to supply a list of ports to add to the host.
