Error description
*************************************************************** * USERS AFFECTED: * Customers with a logical partition managed by an HMC may * experience the rmcd core dump. * The core dump will lead to a node failure on nodes running * PowerHA SystemMirror v7 with RSCT 3.1.4.0 or higher, or * Tivoli System Automation for Multi-Platform (TSAMP) at any * RSCT level, if holding critical resources. *************************************************************** * PROBLEM DESCRIPTION: * It is possible for an IBM.ServiceEvent message to be generated * from an HMC which the RMC subsystem on an LPAR will core dump * when attempting to handle. * The bad message is not predictable or deliberately * reproducable, and is usually a rare occurrence. * The reason behind the bad message on the HMC is not yet * understood, so the scope of this fix will simply be for RMC * to ignore the message and not fail as a result. *************************************************************** * RECOMMENDATION: * Interim fixes for PowerHA 7 customers at the latest SP levels * of 6.1.9, 7.1.3, 7.1.4, and 7.2.0 are available from: * https://ibm.biz/PowerHAFixes * (Ifixes for older levels, or for other cluster types, can be * requested from IBM service on an as-needed basis.) ***************************************************************

Problem conclusion
The reason for the bad registration is not yet understood, so the scope of this fix will simply be to ignore the message and not fail. If more information is uncovered in the future about how the message is generated, that will be addressed as a separate issue (and likely not involving an APAR, if it is limited to an HMC change).
