Error description
************************************************************** * USERS AFFECTED: * Systems running the AIX 7200-02 Technology Level * with devices.common.IBM.ethernet.rte at 7.2.2.0. ************************************************************** * ERROR DESCRIPTION: * On AIX 7.2 TL2, with an EtherChannel device configured in * Network Interface Backup (NIB) mode, if there is an issue * with the primary adapter which causes the etherchannel * to failover to the backup adapter, network communication may * fail even over the backup adapter, causing a total loss of * network communication on the LPAR. * * This happens because after failover to the backup adapter, * the EtherChannel may use the MAC address of the backup * adapter rather than continuing to use the MAC address of the * primary adapter. * * To avoid this problem, the fix can be applied, or as a * workaround, configure the EtherChannel attribute alt_addr * and modify use_alt_addr to "yes". ************************************************************** * RECOMMENDATION: * Install APAR IJ01263. * Prior to fix availability, an interim fix is available from * either * ftp://aix.software.ibm.com/aix/ifixes/ij01263/ * https://aix.software.ibm.com/aix/ifixes/ij01263/ * The ifix can be installed using Live Update (LU). * If LU is not used, installation of the ifix requires a * reboot. **************************************************************
Local fix
Problem summary
Network outage after failover occurs, that is backup adapter is active.
Problem conclusion
Make primary adapter's mac address be Etherchannel's mac address
