Universal Replicator for z/OS® Software Error Codes

Storage Navigator computers display an error message when an error occurs during URz operations. The error message describes the error and displays an error code consisting of four digits. The error message may also include a USP V SVP error code. If you need to call the Hitachi Data Systems Support Center for assistance, please report the URz and SVP error code(s). Please refer to Storage Navigator Messages for a list of error codes displayed on the Storage Navigator computers.
