Connectivity (Basic Information)
A list of the host affinity groups is displayed.
Host affinity is a group that defines the association between a "Host Group", a "Port Group", and
a "LUN Group".
The host affinity function is used when connecting a specific host group (multiple servers) via
switches. By defining the association between a "Host Group", a "Port Group" and a "LUN
Group", security is improved since the volumes that the host recognizes can be limited. In addi-
tion, by configuring the groups of hosts (HBAs) and ports that access the same LUN group, GUI
operation can be simplified.
