Sun Microsystems 6U manual Follow these rules when creating /etc/hostname.qfeinstance files

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.

	Instance	Adapter Ethernet
File Name	Number	Network Interface
/etc/hostname.qfe0	0	0
/etc/hostname.qfe1	1	1
/etc/hostname.qfe2	2	2
/etc/hostname.qfe3	3	3

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).
