Error description
************************************************************** * USERS AFFECTED: * Systems running the AIX 7200-00 Technology Level * with devices.ethernet.shi.rte at the 7.2.0.6 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: * An interim fix is available from either * ftp://aix.software.ibm.com/aix/ifixes/ij08785/ * https://aix.software.ibm.com/aix/ifixes/ij08785/ * Installation of the ifix requires a reboot. **************************************************************
Local fix
Disable the livedump feature: #‌‌ dumpctrl ldmpoff -P #‌‌ bosboot -a #‌‌ shutdown -Fr
