Chapter 4 Configuring the Network Software 43
In the preceding example, the four SUNW,qfe instances are from a Sun Quad
FastEthernet 6U CompactPCI adapter. The path_to_inst file contains the full
device path names to the four SUNW,qfe instances, the instance numbers (shown in
bold type), and the driver names (qfe). Refer to the path_to_inst(4) man page for
more information about this file.
You will need to know the instance numbers when creating the
/etc/hostname.qfeinstance files in Step 3.
Note – Refer to your system’s service manual for more information on how the
adapter’s device path names correspond to the CompactPCI slot numbers in the
system. For example, the /pci@1f,0/pci@1/pci@1/pci@a/SUNW,qfe@x,1 path
names shown above correspond to I/O slot 7 of a Netra ct 800 server.
3. Create an /etc/hostname.qfeinstance file for each network interface you plan to
use.
For each file, replace instance with the instance number you found in Step 2. For
example, if you want to use all of the network interfaces from the example in Step 2,
you must create four files.
Follow these rules when creating /etc/hostname.qfeinstance files:
■ Do not create /etc/hostname.qfeinstance files for adapter network interfaces
you plan to leave unused.
■ The /etc/hostname.qfeinstance file must contain the host name for the
appropriate network interface.
■ The host name must be different from any other host name of any other interface.
For example: /etc/hostname.hme0 and /etc/hostname.qfe2 cannot have
the same host name.
■ The host name must have an IP address entered in the /etc/hosts file (see
Step 4).
