5.2.3.11.3 SVTRMR Usage Considerations

Mount time and the mount request type are key statistics to
 track in this file.  Monitoring mount time trends and mount
 characteristics can provide the Storage Administrator with
 information useful in making performance and tuning
 recommendations.
 
 Trending the eight RTD mount time distribution buckets
 supports identification of possible performance issues.  If a
 significant number of mounts are falling into the higher
 distribution bucket elements, meaning they are excessively
 long, a detailed analysis should be performed to determine
 the reason for the excessive mount time.  It may be due to
 tape drive contention, robot contention, library maintenance
 conflicting with production batch, and so on.
