In a command, the specified target system was not a member of the sysplex, or the specified target system name was too long.
If the specified system name is correct and the JES3 release installed is prior to JES3 5.2.1, the error might have been caused by the presence of JES3 modules and an absence of the NOJES3 parameter in the IEASYSxx parmlib member.
The system does not process the command.
Reenter the command, using the correct target system name.
