DFSMShsm was about to perform the indicated function on the volume with volume serial number volser. However, the volume was already being processed. If one character appears for the procid, the volume is being processed by another processing unit. If HOST=THIS HOST appears, another function is being performed on the volume within the same processing unit. For automatic processes, this message is issued after all attempts to retry the process on this volume fail.
The requested processing on the volume is not performed. DFSMShsm processing continues. For automatic functions, this volume is not processed for this cycle day.
After the current function being performed on the volume ends, reissue the command that caused processing to be attempted on the volume. If you suspect the record should not be serialized (the information in the processing unit identifier field of the record is no longer valid), you can use the FIXCDS command to reset the processing unit identifier field. This field is not valid if a processing unit fails while the task running under that processing unit serializes the record. The LIST command with the HOST parameter can be used to list the DFSMShsm control data set records serialized by a specified processing unit.
