You cannot set a specific time to start performance monitoring.
CAUTION: When Auto is set, all the V-VOL pages may not be completely migrated in one
cycle. In the next cycle, migration starts by updating information for the last processed V-VOL.
At that point, the collection of performance monitoring information is switched to the current
cycle.

15. From the Relocation Speed option, select the page relocation speed to use when performing
relocation.
You can set the speed to: 1(Slowest), 2(Slower), 3(Standard), 4(Faster), and 5(Fastest). The
default is 3(Standard). If you want to perform tier relocation at high speed, use the 5(Fastest)
setting. If the speed specified is slower than 3(Standard), the data drive load is low when tier
relocation is performed.
