Promoting agent and its related targets to Management Service failed probably due to target type meta version present on the agent is not present on the OMS.Make sure that the plug-in version deployed on agents is the same as that of the version on the OMS. Also, the agent should be on the same bundle patch version as that of the OMS.For more details, check <AGENT_INST>/sysman/log/gcagent.log on agent and emoms_pbs.log on the OMS.
Fix the cause of the error and retry the operation (or) manually run the following commands on the remote host
/u01/app/oracle/agent/agent_inst/bin/emctl start agent
/u01/app/oracle/agent/agent_inst/bin/emctl config agent addinternaltargets
