Error description
************************************************************** * USERS AFFECTED: * Systems running the AIX 7200-02 Technology Level * with * devices.ethernet.lnc2.rte below the 7.2.2.17 level * or * devices.ethernet.lnc.rte below the 7.2.2.17 level. ************************************************************** * ERROR DESCRIPTION: * Network adapters using the 'lncentdd' and 'lnc2entdd' * drivers may experience issues due to unintended flash writes * during the adapter port open/close operations. * Affected network adapters currently include the following * Feature Codes: * EN15, EN16, EN17, EN18, EN0H, EN0J, EN0M, EN0N, EN0K, EN0L. * * These issues have been primarily seen when the adapter has * some unused ports with no IP address configured on them, * and performance/health monitoring tools repeatedly open and * close those unused ports. * * We have seen the following issues occur: * - HW_TMP_ERR for the affected adapters seen in the errlog * - adapter ports get into a dead state, and remain unusable * until partition reboot * - adapter permanently failing to configure, requiring * adapter replacement * * Find out if a system has any adapters using an affected * driver with lsdev, for example: * * # lsdev -F "name ddins" | grep -e lncentdd -e lnc2entdd * * Note: on a VIOS, this must be run as root using * 'oem_setup_env'. * * As a workaround before applying the fix, a 'dummy' IP * address can be configured on the unused ports. This will * prevent the frequent open/closes of the adapter ports * monitoring tools. ************************************************************** * RECOMMENDATION: * Install APAR IJ10371. * Prior to fix availability, an interim fix is available from * either * ftp://aix.software.ibm.com/aix/ifixes/ij10371/ * https://aix.software.ibm.com/aix/ifixes/ij10371/ * Installation of the ifix requires a reboot. **************************************************************
