Host Affinity Creation

Host Affinity Creation
This function creates a new host affinity by specifying already registered "Host Group", "CA Port Group", and "LUN
Group".
The host accesses the volumes via the defined paths. When host affinity is configured, the volumes that are
referenced by hosts can be restricted.
The maximum number of connectable hosts (the maximum number of Host Bus Adapters [HBAs]) per port is
256 (32 for the ETERNUS DX60 S5).
Caution
A host can be a member of multiple host groups. In addition, a CA port can be a member of multiple CA
port groups. However, only one LUN group can be allocated to a combination of host and port when
configuring host affinity.
The procedure to create a host affinity when the target connection is "Host Group - CA Port Group" is as follows:

Click [Create Host Affinity] in [Action].
