Figure 8-10. Removing a Child from a Mirror
In Figure 8-11 a child is removed from a mirrored volume with two children.
This breaks the mirror. If the mirrored volume is exposed or attached to a
LUN, the source volume retains the LUN. There is no need to reassign a LUN
to the remaining source volume. All read-write operations will be executed
without a break in service.
