Figure 81. Removing a Child from a Mirror

In Figure 82, 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.
