keyword specifies that if FlashCopy® is
used to perform
the CONSOLIDATE operation, a Peer-to-Peer Remote Copy
(PPRC) primary volume can 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:
For more information about IBM® Remote Pair FlashCopy, Metro Mirror, also known as synchronous Peer-to-Peer Remote Copy (PPRC), and other copy services functions, see z/OS DFSMS Advanced Copy Services. |
