DFS0455I I/O ERROR ON xxx DURING mmm OPERATION

Explanation

The Log Recovery utility, DFSULTR0, encountered an I/O error on data set xxx while processing in mode mmm. The value of mmm is CLS, DUP, or REP. xxx consists of a descriptive name of the data set plus the ddname.

The values for xxx are:
  • INPUT OLDS ddname
  • INPUT SLDS ddname
  • OUTPUT LOG ddname
  • NEXT OLDS ddname

System action

If the I/O error occurs on a dual data set, processing continues using the alternate data set. Otherwise, the Log Recovery utility terminates processing.

Programmer response

If the Log Recovery utility fails (that is, return code = 8), do one of the following:
  • If the error occurred on the interim log data set either during REP mode, input OLDS, or next OLDS, run DUP mode to close or recover the data sets.
  • If the error occurs on the interim log data set during DUP mode or during an output log, rerun the job and specify another drive or volume.
