Error description

  • **************************************************************
* USERS AFFECTED:
* Systems running the AIX 7100-05 Technology Level
* with devices.ethernet.shi.rte below the 7.1.5.30
* level.
  **************************************************************
* ERROR DESCRIPTION:
* Possible network outage can occur with adapters using the
* shientdd driver.  The outage may be temporary or may require
* rebooting the LPAR to recover.
*
* Find out if a system has any adapters using an affected
* driver with lsdev, for example:
*
* # lsdev -F "name ddins" | grep shientdd
* Note: on a VIOS, this must be run as root using
* 'oem_setup_env'.
*
* We have seen this occur when changes occur on the physical
* network, such as switches restarting or cables becoming
* disconnected.  When the driver is handling these events, it
* may incorrectly trigger a livedump of the adapter, causing
* the adapter to be reset and network traffic through the
* adapter to cease.  This may be temporary or may require
* rebooting the LPAR to recover the adapter.
  **************************************************************
* RECOMMENDATION:
* Install APAR IJ08480.
* Prior to fix availability, an interim fix is available from
* either
* ftp://aix.software.ibm.com/aix/ifixes/ij08480/
* https://aix.software.ibm.com/aix/ifixes/ij08480/
* Installation of the ifix requires a reboot.
  **************************************************************

Local fix

  • Disable the livedump feature:
#‌‌ dumpctrl ldmpoff -P
#‌‌ bosboot -a
#‌‌ shutdown -Fr

Problem summary

  • shientdd driver takes adapter livedumps and logs permanent
error SHIENT_SW_ERR in the errpt.

Problem conclusion

  • Modified the code which was wrongly triggering the livedump.

Temporary fix
