IBM's computer systems contain mechanisms designed to reduce the possibility of undetected data
corruption or loss. This risk, however, cannot be eliminated. Users who experience unplanned outages,
system failures, power fluctuations or outages, or component failures must verify the accuracy of
operations performed and data saved or transmitted by the system at or near the time of the outage or
failure. In addition, users must establish procedures to ensure that there is independent data verification
before relying on such data in sensitive or critical operations. Users should periodically check IBM's
support websites for updated information and fixes applicable to the system and related software.
