The extent that is already set as the copy target cannot be used as a copy source extent to create
a new Compatible FlashCopy relationship. You cannot create a cascaded Compatible FlashCopy

Copy modes
When you establish a relationship, Compatible FlashCopy allows you to select the mode to run
the copy operation between COPY mode and NOCOPY mode. (NOCOPY mode can be selected
in Compatible FlashCopy SE).
When you select COPY mode, Compatible FlashCopy copies all the data in the S-VOL to the T-VOL.
This process is called background copying. Compatible FlashCopy automatically withdraws the
pair when the background copying is complete. When you select NOCOPY mode, the background
copying operation will not be performed.
