Manual execution mode
You can start and stop performance monitoring and tier relocation at any time. You should
keep the duration of performance monitoring to less than 7 days (168 hours). If performance
monitoring exceeds 7 days, then monitoring stops automatically.
Manual execution mode starts and ends monitoring and relocation at the time the command
is issued from Remote Web Console or RAID Manager. You can use scripts, which provide
flexibility to control monitoring and relocation tasks based on a schedule for each day of the
week.
In manual execution mode, the next monitoring cycle can be started with the collection of
monitoring data and tier relocation operations performed in parallel. Data from these parallel
processes are stored in two separate fields.
◦ Data while monitoring is in progress in the next cycle.
◦ Fixed monitoring information used in tier reliocation.

Case 1: If the second collection of the monitoring information is finished during the first tier
relocation, the latest monitoring information is the second collection. In that case, the first
collection of monitoring information is referenced only after the first tier relocation has
completed.
