9.2.3.3
Create SAS Port Group
This function creates a new SAS port group, and registers the port to be a member.
A SAS port group is a group of SAS-CA type ports that are connected to the specified host
group. This function configures the host affinity setting for each SAS port group.
•
The maximum number of port groups per device 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.
An error screen appears in the following conditions:
•
When the port group name overlaps with an existing port group
name (port group names cannot overlap with any other port group
names, irrespective of the CA types.)
•
When the total number of ports has exceeded the maximum
number for the ETERNUS DX Disk storage system
•
When no ports are registered in a port group, or when nine or
more ports are registered in a port group
•
When the specified port does not exist in the ETERNUS DX Disk
storage system
•
When the port mode of the selected port is other than "iSCSI"
•
When the port mode of the selected port is other than "CA"
•
When there are ports of which affinity mode is enabled (On) and
disabled (Off) existing together
Click the [Done] button to return to the [Port Group] screen.
•
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.
•
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/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/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.
