HP XC System Software Administration Guide Version 3.2

Table 22-2 Modelmap Values (continued)
ValuesColumn
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 document, 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 document, you will change this value to a more definitive
value.
External
1
The entries in the platform_vars.ini file for the HP Integrity rx8620 model type must specify Ethernet devices,
not PCI bus IDs.
2 This value can be used reliably only when all nodes of that model type have zero or one NIC available after matching
up the explicitly specified PCI bus ids to their corresponding logical networks (Admin/Interconnect/External), that
is, when the choice of NIC for offboard is unambiguous.
Use the information from the previous section to update the platform_vars.ini configuration
file.
1. Log in to the head node as the superuser (root).
2. Change to the /opt/hptc/config directory.
3. Make a backup copy of the platform_vars.ini configuration file, for example:
# cp platform_vars.ini platform_vars.ini.BAK
4. Use the text editor of your choice to open the platform_vars.ini configuration file.
5. Locate the stanza for the node's model type in the file.
6. Determine which modelmap variable assignment line applies to your needs:
The lines that begin with the string Ethernet are provided for systems that use Gigabit
Ethernet for the Interconnect switch.
The lines that begin with the string !Ethernet are provided for systems that use an
interconnect other than Gigabit Ethernet.
Determine the line that corresponds to the final number of Ethernet devices for the node.
