Validating a system/lpar under the System Registry tab fails, the MSMSPNPM was is defined on the SPNPARMS DD but CCIDSCSV is not spawned and in the MSMTC jobs these messages can be found:
+MSMD2100I SEARCH ON=sysname
+MSMD2103I NO MATCHING SYSTEM NAME
The system name defined under the System Registry tab must be defined in SYS1.PARMLIB(IEASYSnn). Verify that the system name under the System registry tab matches the system name specified on the SYSNAME parm in IEASYSnn.
