To start one or multiple FlashCopy mappings that do not belong to a consistency group, 
complete the following steps:
1. Open the FlashCopy Consistency Gr oups, or FlashCopy Mappings window.
2. Right-click the FlashCopy mappings that you want to start and select Start, as shown in 
Figure 11-59.
Figure 11-59   Starting FlashCopy mappings
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.
11.2.17  Stopping FlashCopy mappings
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.
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.
