9.2.3.1 Create FC Port Group
This function creates a new FC port group, and registers the port to be a member.
An FC port group is a group of FC-CA type ports that are connected to the specified host group. This function
configures the host affinity setting for each FC port group.
• The maximum number of port groups per storage system is 128, irrespective of the CA types.
• The maximum number of ports per port group is 8.
• A port can be a member of several port groups.
The procedure to create an FC port group is as follows:
Procedure
1 Click [Create FC Port Group] in [Action].
• Registration of the port is necessary to create a port group. A port group cannot be created if the port to
be a member has not been registered from GUI.
• Only ports with "CA" or "CA/RA" as the port mode can be added to a port group. Ports with "RA" as the port
mode cannot be added to a port group.
• A port with the affinity mode enabled ("ON") and a port with the affinity mode disabled ("OFF") cannot
exist together in a port group.
- The affinity mode ("ON" or "OFF") of a port group is decided when the host affinity setting has been
configured on the corresponding port group. All of the member ports in a port group have the same
affinity mode.
- The affinity mode ("ON" or "OFF") of a port group is not changed until the host affinity setting has
been released from the corresponding port group.
- When one port is registered in several port groups, and the host affinity setting has been configured
on one of the port groups including the corresponding port, the same affinity setting is configured on
all the port groups, which include the corresponding port, and also on the member ports.
- Ports without the host affinity setting can be members of a port group, regardless of whether the
affinity mode for the group is enabled ("ON") or disabled ("OFF").
