A host has a single iSCSI node name for alliSCSI ports. You need these identifiers when you are manually creating initiator groups(igroups) on the storage system.The storage system also has WWPNs and an iSCSI node name, but you do not need them toconfigure the host.Recording the WWPNRecord the worldwide port names of all Fibre Channel ports that connect to the storagesystem. Each HBA port has its own WWPN. For a dual-port HBA, you must record twovalues; for a quad-port HBA, record four values.Tip: The Windows Host Utilities installer checks for required Windows hotfixes.
