3.5 Host Interface Management
This section explains the commands related to the management of the host interface.
The functions to manage the host interface are as follows:
• Host identifiers (Host Alias)
• Affinity group
• Mapping (associating an affinity group with a host identifier)
• Mapping (associating volumes with LUNs)
• Host response
• Host sense
• Resetting group
• iSCSI Ping
• Port Groups
• Host Groups
• Host LU QoS

Host interface type
There are four host interface types; Fibre Channel (FC), Serial Attached SCSI (SAS) and Internet Small
Computer System Interface (iSCSI), and Fibre Channel over Ethernet (FCoE).
The speed for each type of host interface is as follows:
Fibre Channel (FC)
Fibre Channel over Ethernet (FCoE)
Serial Attached SCSI (SAS)
Internet Small Computer System Interface (iSCSI)
■ Host Affinity Mode
There are two mapping methods to associate volumes with host LUNs. They should be separated and used
depending on whether Host Affinity Mode is enabled. Host Affinity Mode can be set to each host interface port
respectively. When Host Affinity Mode is enabled, it can associate an affinity group (the definition to associate
volumes with host LUNs) with the host HBA. When Host Affinity Mode is disabled, it does not require an
affinity group, and can associate volumes with the host LUNs from all the hosts. This mode can be set with the
"set fc-parameters" command.
■ Affinity group
If only Host Affinity Mode is enabled, affinity groups can be created. The affinity group is a definition to
associate volumes with host LUNs.
