• When a host and the ETERNUS DX400/DX8000 series are connected
via FC-CA or iSCSI-CA, there are two ways for a host to recognize
Logical Volumes in the ETERNUS DX400/DX8000 series. One is [Set
LUN Mapping], and the other is the Host-Affinity function, which relies
on [Set Host World Wide Name(s)]/[Set iSCSI Host], [Set Affinity Group]
and [Allocate Host-Affinity Group]. [Affinity Mode] in [Set CA
Parameters] for each FC-CA Port or iSCSI-CA Port determines which
function to use. If [Affinity Mode] is [ON (Enabled)], the Host-Affinity
function is enabled, whereas [Set LUN Mapping] is enabled if [Affinity
Mode] is [OFF (Disabled)].
• The Host-Affinity function is a device security function for open system
servers which is supported by Fibre Channel CAs (FC-CA) and iSCSI-
CAs. To use the Host-Affinity function, [Set Host World Wide Name(s)]/
[Set Host iSCSI], [Set Affinity Group], and [Allocate Host-Affinity Group]
are required.
• "FC8G" indicates FC with a maximum transfer speed of 8Gbps.
