Analyze Why the Device Link Is Missing
If the ifconfig(1M) command cannot find a device, the following message is displayed in
cannot open igb0; link doesn't exist
- Check the OS.
If the OS is Oracle Solaris 10 8/11, skip to Step 2.
If the OS is Oracle Solaris 11, use the dladm(1M) command to plumb the driver.
- Check that the EM is seated properly in its slot, that the cables
are properly attached, and that the LEDs are functioning.
- Use the prtconf(1M) or scanpci(1M) command to ensure that the device is installed.
- If the device exists, check the /etc/driver_aliases file to ensure that the file
contains an igb entry that corresponds to the name for the device.
- If the entry exists, check the /etc/path_to_inst file to ensure that the file
contains an igb entry.
Removing a device and reseating it in another slot does not always clean
up the device tree. If this is the case, you must remove the
device tree and reboot the system. See Oracle Solaris Administration: Network Interfaces and Network Virtualization for more information.
