Change RPO and intervalThe required RPO can be changed as illustrated in Figure 6-17 and the GUI selects a newinterval for the schedule. For example, as shown in Figure 6-18, the RPO was changed to 1hour (01:00:00). The schedule selected is 15 min. This schedule can then be changed fromthe Properties panel. There is a selection list of available intervals, as shown in Figure 6-19on page 163.Figure 6-17 Change RPOFigure 6-18 New RPO value162 IBM XIV Storage System: Copy Services and Migration
