It takes a certain amount of time for the synchronization between the split mirror and the storage device that is the source of the split mirror. This refers to the technology to reduce this time. The fast mirror resynchronization technique requires a table of changes to the original data set after separation has started, because most of the data has not changed. When the separated mirror is added to the original volume concentration area again, only the data items listed in the change table will be copied (from the original location to the separated mirror), instead of copying the entire device content.
