The program has read forward all the specified volumes of the standard tape label data set or DASD data set, starting from the volume that was selected during OPEN processing. None of the processed volumes end with EOF (end of file) labels. EOF labels would indicate the end of the last volume for the data set.
The system calls the label anomaly installation exit routine. The installation exit provided by IBM takes no action, and therefore the system ignores the condition. The label anomaly exit of your installation might cause the system to issue ABEND 413 rc 5C and message IEC145I.
This is either an error, an intentional action by the user, or the tapes are from another operating system. If you have a system automation product that can distinguish between a user error and the other causes, you may be able to configure that product to correct the error or to cancel or stop the job. DFSMSrmm can correct the volume list.
Possible error. Check whether the volumes on the DD statement or the dynamic allocation are complete.
