Specifies that either the maximum service time threshold (<msec>) that is used to discover
overutilized physical disks, or the physical disks that have the highest maximum service
times (

exceeds the specified threshold is considered a candidate for load balancing.

Specifies that either the average service time threshold (<msec>) that is used to discover
overutilized physical disks, or the physical disks that have the highest average service time

RESTRICTIONS
Use of this command requires a Dynamic Optimization license. Contact your local 3PAR
representative for information.
The system does not allow multiple tunepd processes with the -chstat on or –chstat
force
options to run concurrently.
If one or more chunklet statistics collection processes are running, the tunepd command
exits to prevent possible tunepd –chstat on processes running simultaneously.
Use the –chstat force option only when you have verified that no other tunepd
processes are running.
