Error description

  • When using the PROTECT STGPOOL command to protect extents from a
    server that is 7.1.7.0 or above (including 8.1.0.0) that are
    compressed by the server to a target server that is below
    7.1.5.0, the data extents can be sent to the target server
    without being uncompressed.  This can cause the extents to be
    marked as damaged on the target server because server side
    compression was introduced in the 7.1.5.0 level.
