■ CA port group
A CA port group is a group of ports that have the same port settings. Ports that access the same LUN group,
such as the ports that use multipath connections to servers and the ports that connect servers that configure a
cluster, are set to a single port group. The single port group can be allocated to multiple host groups. Once the
CA port group is created, the settings of all the ports that belong to the port group can be changed by simply
changing the settings of the port group.
■ LUN group
A LUN group is a group of LUNs that are accessed from the same host group and CA port group.
■ Mapping method
The following is an example when Host Affinity Mode is enabled:
CLI> set fc-parameters -port 000 -host-affinity enable
CLI> create raid-group -name r1 -level 1 -disks 006,007
CLI> create volume -name v -count 3 -rg-name r1 -type open -size 256mb
CLI> create lun-group -name a1 -volume-name v0,v1,v2 -lun 0-2
CLI> create host-wwn-name -name h1 -wwn a00000e0d0100000
CLI> set host-affinity -host-name h1 -lg-name a1 -port 000
Procedure
1
Enable Host Affinity Mode of host interface port 000. (FC)
2
Create a RAID group named "r1".
3
Create volumes named "v0", "v1" and "v2" in the RAID group named "r1".
4
Create a LUN group named "a1", the mapping relation of volume named v0/v1/v2 and LUN
0/1/2.
5
Register a host WWN named "h1" (FC).
6
Use mapping (host affinity mode) to set the relationship between host interface port 000,
the LUN group named "a1", and the host identifier named "h1".
