/SM590000Suspended
The mapping started, but it did not complete. Access to the metadata is lost, which causes 
both the source and target volume to go offline. When access to the metadata is restored, 
the mapping returns to the copying or stopping state and the source and target volumes 
return online. The background copy process resumes. If the data was not flushed and was 
written to the source or target volume before the suspension, it is in the cache until the 
mapping leaves the suspended state. 
Summary of FlashCopy mapping states
Table 11-2 lists the various FlashCopy mapping states, and the corresponding states of the 
source and target volumes.
Table 11-2   FlashCopy mapping state summary
11.1.11  Multiple target FlashCopy
A volume can be the source of multiple target volumes. A target volume can also be the 
source of another target volume. But, a target volume can only have one source volume. A 
source volume can have multiple target volumes, in one or multiple consistency groups. A 
consistency group can contain multiple FlashCopy mappings (source-target relations). A 
source volume can belong to multiple consistency groups. Figure 11-12 on page 453 shows 
these different possibilities.
Every source-target relation is a FlashCopy mapping and is maintained with its own bitmap 
table. There is no consistency group bitmap table.
