To start one or multiple FlashCopy mappings that do not belong to a consistency group,  complete the following steps: 1. Open the FlashCopy Consistency Groups, or FlashCopy Mappings window. 2. Right-click the FlashCopy mappings that you want to start and select  Start , as shown in  Figure 11-59. You can check the FlashCopy state and the progress of the mappings in the Status and  Progress columns of the table, as shown in Figure 11-60.  FlashCopy Snapshots are dependent on the source volume and should be in a “copying”  state if the mapping is started. FlashCopy clones and the first occurrence of FlashCopy backup can take a long time to  complete, depending on the size of the source volume and on the copyrate value. The next  occurrences of FlashCopy backups are faster because only the changes that were made  during two occurrences are copied. For more information about FlashCopy starting operations and states, see 11.1.10, “Starting  FlashCopy mappings and Consistency Groups” on page 450. Figure 11-60 FlashCopy mappings status and progress examples Figure 11-59 Starting FlashCopy mappings 11.2.17 Stopping FlashCopy mappings Important:  Only FlashCopy mappings that do not belong to a consistency group can be  stopped individually. If FlashCopy mappings are part of a consistency group. They can only  be stopped together by using the consistency group  stop  command. The only reason to stop a FlashCopy mapping is for incremental FlashCopy. When the first  occurrence of an incremental FlashCopy is started, a full copy of the source volume is made.  When 100% of the source volume is copied, the FlashCopy mapping does not stop  automatically and a manual stop can be performed. The target volume is available for read  and write operations, during the copy, and after the mapping is stopped. Chapter 11. Advanced Copy Services  495
