Figure 7 Collection of monitoring data to tier relocation workflow in manual execution mode
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.
Figure 8 Second collection of monitoring information finishes before the first tier relocation is
complete
Case 2: When tier relocation is performed with the first collection of monitoring information, the
second collection of monitoring information can be performed. However, the third collection cannot
be started. Because only two fields are used store collected monitoring information, the third
collection cannot be overwritten.
