subtask name of unavailable subtask
The mainframe task is not able to process a command because the necessary subtask is not running.
The command is discarded.
Use the SHOW TASK console command (see Appendix A) to check the status of the VP390 subtasks. If subtask is in the list of subtasks but does not have an "UP" status, use the INIT command to restart the subtask. If subtask is not in the list of subtasks, then add it to the SYSIN deck and restart the VP390 job.
