Recover From a Port Hang (Oracle Solaris)

  1. Take one of these actions.
    • If the interface encounters a soft hang, replumb the device.

      Use the ipadm command.

    • If the interface encounters a hard hang, reboot the server.

    • If the interface encounters another hard hang, try to capture the trace information by using the dtrace command. For example:

      # detrace -F -m 'i40e{trace(timestamp)}'
      >/tmp/dtrace.out
    • If the server is panicked, retrieve the crash dump in /var/crash.

    • If the interface encountered a hard hang or a panic, file a CR at My Oracle Support.

      Attach the last page of the dtrace command output or the crash dump file to the CR.

  2. Check for the driver statistics.
    # kstat i40e:* :statistics
  3. Use the following parameters for performance tuning in i40e.conf:
