For the step of the job, open processing is trying to position a tape volume serial number on a device to a specific file in order to open that file. Open processing has retried positioning the tape to the correct file (at least once), but cannot find the file because the file is not known. Open processing issued this message to ask if it should retry positioning the tape to the correct file again.
If you wish open processing to retry positioning the tape to the correct file, enter REPLY xx, ‘R’. Otherwise, to continue with the ABEND already in progress, enter REPLY xx, ‘U’. xx is the message reply identification for this message.
