specifies that if FlashCopy® is
used to perform the copy operation,
a Peer-toPeer Remote Copy (PPRC) primary volume is allowed to become
a FlashCopy target volume. Use
the following sub-keywords to specify whether
the device pair is allowed to go to duplex pending state if the target
volume of the FlashCopy operation
is a metro mirror primary device:
Attention: When you specify FCTOPPRCPrimary or FCTOPPRCPrimary(PRESMIRNONE), the FlashCopy operation causes a PPRC primary volume to become a FlashCopy target volume. A Metro Mirror or Global Copy pair currently in full duplex state, goes into a duplex pending state when the FlashCopy relationship is established. When Metro Mirror or Global Copy completes the copy operation, the Metro Mirror or Global Copy pair goes to full duplex state. To prevent Metro Mirror or Global Copy pairs from going to duplex pending state during FlashCopy operation, you must specify FCTOPPRCPrimary(PRESMIRREQ). Note:
