IJ19137: ADAPTER STATISTIC RESET MAY FAIL IN RARE CASES APPLIES TO AIX 7100-05

APAR status

• Closed as program error.

Error description

• When attempting to reset ethernet statistics for mlxentdd
  device (Device Type: 40GbE PCIe3 CX3 Network Adapter)
  using either:
  entstat -r entX
  or
  netstat -Zv
  
  The counters for "Receive Errors" may not reset to 0 for
  SEA/Etherchannel/Real adapter due to the counter for
  "Receive Frame Errors" under the "Extended
  Interface Statistics" not being reset to 0 when an
  interface is configured.
  

Local fix

• These counters should reset on reboot of the OS
  -or-
  It may be possible to reset the statistics by bringing
  down the interface of the adapter if configured:
  #ifconfig enX down detach
  #entstat -r entX
  #chdev -l enX -a state=up
  #mkdev -l inet0
  
  Where enX/entX corresponds to the adapter involved.
  Note: Be aware that this can result in an outage for
  the network serviced by that interface.
  

Problem summary

• The commands 'netstat -Zv as well as entstat -r entX'
  will not clear some statistics for the adapters
  using mlxentdd driver.
  

Problem conclusion

• Fixed the problem in the source code.
  

Temporary fix
