Error description
SMAPI does not detect the situation in which a VM system is trying to join an ensemble with an ensemble mac prefix that matches one already in use. That is, it is not detected when a VM system attempting to join an ensemble is a clone of another VM system already in the cluster.

Problem summary
**************************************************************** * USERS AFFECTED: z/VM 6.2 Users of Unified Resource Manager * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** Cloning a VM System in an Ensemble causes communication failures within the Ensemble. zManager is being changed to send a command to SMAPI to leave the ensemble if the VM system is trying to join the ensemble with an ensemble mac prefix that matches one already in use. This would indicate the VM system attempting to join is a clone of another VM system already in the cluster.
Problem conclusion
SMAPI has been changed to perform the following steps when the VM system is identified as a clone of another VM system already in the Ensemble. 1. Execute ensemble termination for that z/VM System. 2. Send a message to the VM System Operator that this VM system has been identified as a Clone, and must be re-ipled to join the ensemble. 3. Update the SMAPI LOG file to indicate that the VM System was identified by zManager as a Clone. . NOTE: Installations using the Unified Resource Manager for integrated systems management of z/VM must apply bundle #25 for driver D15 (zEC12 / zBC12). Bundle details, when available, can be found in the 2827DEVICE or 2828DEVICE hardware PSP bucket and also at the z/VM Unified Resource Manager web page: http://www.vm.ibm.com/service/vmrequrm.html
