Specifies the interval, in minutes, that the command enters standby mode between iterations using an integer greater than 0.

If this option is not specified, statistics for ports are not displayed. -pdstat Specifies that statistics for all physical disks, rather than only those with high service times, are displayed. If this option is not specified, statistics for all disks are not displayed. -chstat Specifies that chunklet statistics are displayed. If not specified, chunklet statistics are not displayed. If this option is used with the -movech option, either on or force must be specified.

SPECIFIERS maxsvct |highest Specifies that either the maximum service time threshold () that is used to discover overutilized physical disks, or the physical disks that have the highest maximum service times (highest). If a threshold is specified, then any disk whose maximum service time exceeds the specified threshold is considered a candidate for load balancing. avgsvct |highest Specifies that either the average service time threshold () that is used to discover overutilized physical disks, or the physical disks that have the highest average service time (highest). If a threshold is specified, any disk whose average service time exceeds the specified threshold is considered a candidate for load balancing.
