Host Affinity Management

This section describes host affinity management.
Host Affinity management provides the following functions:

• Create Host Affinity

• Delete Host Affinity
• Modify Host Affinity
4.1.1 Create Host Affinity
This function creates a new host affinity.
When "Host Group - CA Port Group" is selected for "Target Connection", specify the existing "Host Group", "CA
Port Group", and "LUN Group" settings. When "Host - CA Port" is selected for "Target Connection", select the
existing "Host", "CA Port", "and "LUN Group" settings.
The host accesses a volume via a defined path. Configuring the host affinity can limit the volumes which the
host can recognize.
• The maximum number of connectable hosts (the number of HBAs) per CA port is 256 (32 for the ETERNUS
DX60 S3).
• If a host group has been specified in the "Host Group" field of host affinity, all the member ports of the
assigned "CA Port Group" have the affinity mode configured "ON".
• If "All (all hosts)" has been specified in the "Host Group" field of host affinity, all the member ports of the
assigned "CA Port Group" have the affinity mode configured "OFF".
• When one port is registered in several CA port groups, and the affinity setting has been configured on one
of the CA port groups including the corresponding port, the affinity setting is configured on all the CA port
groups, which include the corresponding port, and also on the member ports.
• CA port groups without a host affinity setting can be used for creating a host affinity regardless of
whether the affinity mode is enabled (ON) or disabled (OFF).
• CA ports without a host affinity setting can be used for creating a host affinity regardless of whether the
affinity mode is enabled (ON) or disabled (OFF).
• A host can be a member of several host groups. In addition, a CA port can be a member of several CA port
groups. However, only one LUN group can be allocated to host and port combinations when configuring
host affinity.
• To change the settings of the host affinities, refer to
• Host groups with the host interface "FCoE" can configure host affinity with CA port groups with CA types
"FC" or "FCoE".
