4.3 CA Port Group Management
• The maximum number of CA port groups per storage system is 128 (with a maximum number of 384 for
the ETERNUS DX8700 S3/DX8900 S3), irrespective of the CA types.
• The maximum number of ports per CA port group is 8.
• A port can be a member of several CA port groups.
• Registration of the port is necessary to create a CA port group. Not all of the ports can be deleted from a
CA port group.
• Only ports with "CA" or "CA/RA" as the port mode can be added to a CA port group. The ports, of which port
mode is "RA", cannot be added to the CA port group.
• Ports that are used for the Storage Cluster function cannot be added to the port group.
• A port with the affinity mode enabled ("On") and a port with the affinity mode disabled ("Off") cannot
exist together in a CA port group.
- The affinity mode ("On" or "Off") of a CA port group is decided when the host affinity setting has been
configured on the corresponding CA port group. All of the member ports in a CA port group have the
same affinity mode.
- The affinity mode ("On" or "Off") of a CA port group is not changed until the host affinity setting has
been released from the corresponding CA port group.
- When one port is registered in several CA port groups, and the host affinity setting has been
configured on one of the CA port groups including the corresponding port, the same affinity setting is
configured on all the CA port groups, which include the corresponding port, and also on the member
ports.
- Ports without the host affinity setting can be members of a CA port group, regardless of whether the
affinity mode for the host group is enabled ("On") or disabled ("Off").
• When a port was added to a CA port group, of which the host affinity setting has been configured, paths
between all the hosts with the host affinity setting and the added port will be configured. To modify the
path between a host and a port, refer to
• When a port in the CA port group for which the host affinity settings are already configured is deleted, the
path from the host to the port is also deleted.
• When creating a new CA port group and registering a port in the CA port group, refer to the following sec-
tions depending on the CA port type.
- "4.3.1 Create FC Port Group" (page 429)
- "4.3.2 Create iSCSI Port Group" (page 432)
- "4.3.3 Create SAS Port Group" (page 433)
- "4.3.4 Create FCoE Port Group" (page 436)
