Incorporating External NICs HowTo

used to determine the values for the Administration port, the Interconnect port, and the
External port or ports, which are assigned to the modelmap variable.
• Interconnect type.
That is, does the system use Gigabit Ethernet for the Interconnect switch or not?
• Ethernet device count.
That is, how many Ethernet devices are detected?
Table 3 Modelmap Values
ValuesColumn
This column contains one of two values:
Ethernet
Indicating a system that uses Gigabit Ethernet for the system
interconnect switch.
!Ethernet
Indicating a system that uses a system interconnect switch other
than Gigabit Ethernet, such as Quadrics QSnet
II
and Myrinet.
One of these values matches the Interconnect type for the system. That match helps
determine which line is used for the modelmap variable.
interconnect
The entry in this column is an expression that describes the number of physical
Ethernet ports (the Ethernet device count).
The first expression that matches the Ethernet device count detected by the system
helps determine which line is used for the modelmap variable.
#of eths
The port specified in this column is used to connect the node to the administration
network of the HP XC system.
Valid values for this column are:
Bus_ID
1
Indicates the hardware PCI bus ID, for example, 20:02.0; this is the
most reliable method for designating a physical Ethernet port.
ethn
Indicates an Ethernet device, starting with eth0.
AdminPort
The port specified in this column is used for the system interconnect.
Valid values for this column are:
Bus_ID
1
Indicates the hardware PCI bus ID, for example, 20:02.1; this is the
most reliable method for designating a physical Ethernet port.
ethn
Indicates an Ethernet device, starting with eth0.
undef
Indicates this value is undefined for interconnect port in this
configuration. This is the case when an interconnect other than Gigabit
Ethernet is used.
offboard
2
Is a placeholder indicating the system chooses from an available
added NIC.
In this HowTo, you will change this value to a more definitive value.
Interconnect
The port specified in this column is used to connect to an external network.
Valid values for this column are:
Bus_ID
1
Indicates the hardware PCI bus ID, for example, 00:03.0; this is
the most reliable method for designating a physical Ethernet port.
ethn
Indicates an Ethernet device, starting with eth0.
undef
Indicates this value is undefined for external port in this
configuration.
offboard
2
Is a placeholder indicating that the system chooses from an available
added NIC.
In this HowTo, you will change this value to a more definitive value.
