Analyze Why the Device Link Is Missing (Oracle Solaris x86)

When you use the ifconfig or ipadm commands and you see an error message similar to the one below, perform these steps.

...
cannot open bnxt0; link doesn't exist
...

1. Check the OS.

   To plumb the driver, refer to the Oracle Solaris ipadm(1M) man page. For information on the network interface parameters, refer to the Oracle Solaris ifconfig(1M) man page.

2. Check that the adapter is seated properly in its slot, that the cables are properly attached, and that the LEDs are functioning.
3. Ensure that the device is installed.

   Use the prtconf or the scanpci command to verify that the device is installed. For more information, refer to the Oracle Solaris prtconf(1M) man page or the scanpci(1) man page.

4. If the device exists, check the /etc/driver_aliases file to ensure that the file contains a bnxt entry that corresponds to the name for the device.
5. If the entry exists, check the /etc/path_to_inst file to ensure that the file contains a bnxt entry.

   Removing a device and reseating it in another slot does not always clean up the device tree. If this occurs, you must remove the device tree and reboot the server. For more information, refer to Managing Network Virtualization and Network Resources in Oracle Solaris 11.3.
