For SPARC servers, like the M series servers, you can use Oracle ILOM to identify the host-DCU assignments, as well as to determine the general health of logical DCU configurations. In addition, for SPARC servers, like the M7-16 servers, which support a DCU service processor proxy (SPP) configuration with redundant service processor modules (SPM), you can use Oracle ILOM to determine the SPM that is actively assigned to manage the DCU system activity. In cases where DCU management access is lost due to a faulty SPP or SPM, you can use Oracle ILOM to change the roles of the controlling SPM.
