If you use IDCAMS REPRO to perform a DSS copy of a log stream offload data set to which the logger function has not fully written, you might receive errors from IDCAMS.

Logger offload data sets are allocated as VSAM linear data sets but are not fully formatted. A tool like IDCAMS REPRO expects data sets to be formatted up to the high used relative byte address (HURBA). Tools such as IDCAMS REPRO that perform logical or sequential data set reads using VSAM access methods fail the copying of log stream offload data sets that are not completely formatted.

If the data set copy fails use a tool such as DSS DUMP/RESTORE that performs a physical copy of the data set. For information on identifying the types of failures that can occur, see z/OS MVS Diagnosis: Reference.
