Copy modes

When you establish a Compatible FlashCopy relationship, you select the mode, COPY or NOCOPY,

for the copy operation.

• COPY: When you select COPY mode, all data in the S-VOL is copied to the T-VOL. This process

is called background copying. When the background copying is complete, the relationship

is automatically withdrawn.

• NOCOPY: When you select NOCOPY mode, the background copying operation is not

performed. Data is moved from the source to the target volume based on access to the S-VOL

or T-VOL as described in the next paragraph. A NOCOPY relationship can be converted to

a COPY relationship (for example, NOCOPY2COPY).
