CHASSISD_FRU_IO_ERROR

May 21, 2016 by Marques Brownlee

The chassis process (chassisd) could not perform the indicated I/O operation on the indicated component (field-replaceable unit, or FRU). This message, when seen, is usually in connection with the craft interface on an M320 or TX device.

When a CHASSISD_FRU_IO_ERROR event occurs, a message similar to the following is reported:

chassisd[1059]: CHASSISD_FRU_IO_ERROR: handle_fpm_write_err: craft interface write error: error setting craft PS LEDs (Unknown error: -1)
chassisd[3195]: CHASSISD_FRU_IO_ERROR: handle_fpm_write_err: craft interface write error: error setting craft LED (Unknown error: -1)
chassisd[25950]: %DAEMON-3-CHASSISD_FRU_IO_ERROR: handle_fpm_write_err: craft interface write error: error setting craft FPC LEDs (Unknown error: -1)

The cause may be either do to a faulty connection to the reported FRU, or the FRU is in a state that is not allowing it to function properly.

Examine the following output to help determine the cause of this message:

show log messages
show log chassisd

Look for any related events that occurred at or just before the CHASSISD_FRU_IO_ERROR message.

  1. During a maintenance window, as it may impact transit traffic, try reseating and/or resetting the connection to the affected FRU device.
  2. If the log messages continue, open a case with your technical support representative to investigate the issue further.
