CPO1284E System system name and sysplex sysplex name is not unique
Explanation
The ACTIVATE GROUPCAPACITY or DEACTIVATE GROUPCAPACITY command has been issued specifying the referenced values for the SYS and PLEX parameters. Multiple LPARs in the domain configuration run systems with the referenced name. This means the capacity group for the command cannot be uniquely identified. The command is ignored.
User response
Specify GROUP and CPC parameters with the command to uniquely identify the capacity group to be changed and retry the command.
