To cancel a background process that was started as the result of an administrative command or from a process (such as migration), complete the following field and then click Finish, or click Cancel to end the task.
Enter the number of the background process you want to cancel. You can obtain the number from the QUERY PROCESS command.
If the process to be cancelled is waiting for a sequential access volume to be mounted, the mount request is automatically cancelled.
Some processes, such as reclamation, will generate mount requests in order to complete processing. If a process has a pending mount request, the process may not respond to a CANCEL PROCESS command until the mount request has been answered or cancelled by using either the REPLY or CANCEL REQUEST command, or by timing out.
Use the QUERY REQUEST command to list open requests, or query the activity log to determine if a given process has a pending mount request.
Note: A mount request indicates that a volume is needed for the current process, but the volume is not available in the library. It may not be available if the administrator has issued the MOVE MEDIA or CHECKOUT LIBVOLUME command, or manually removed the volume from the library.
