What does it fix?

VVM-223 - When the cumulative I/O stats returned by Veritas Volume Manager commands became too large (more than 231), the related parameters failed and stopped collecting data. Thus, metrics for rate-based parameters such as ReadKBytesRate, WriteKBytesRate, IOKBytesRate were not properly reported for volumes, plexes, disks devices and subdisks. The product now stores the actual read, write or total I/O collected since the last collection cycle to avoid values reported by these parameters to grow cumulatively and to reach their limitation.
