Fixed In Version: s390utils-1.23.0-24.el7_2.1
Doc Type: Bug Fix
Doc Text:
Previously, due to a bug in the cpuplugd daemon initialization script, the Cooperative Memory Management (CMM) kernel module was not automatically loaded when necessary. As a consequence, hot-plugging memory could be performed only after manually loading CMM. This has been fixed, and now it is possible to hot-plug memory without manually loading CMM.
