The FCTOPPRCPRIMARY 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:

PRESMIRREQ: specifies that if the target volume is a Metro Mirror primary device, the pair must not go into a duplex pending state as the result of a FlashCopy operations.
PRESMIRPREF: specifies that if the target volume is a Metro Mirror primary device, it would be preferable that the pair does not go into a duplex pending state as the result of a FlashCopy operation. However, if a Preserve Mirror operation cannot be accomplished, the FlashCopy operation is still to be performed.
PRESMIRNONE: specifies that Preserve Mirror operation is not to be done, even if all of the configuration requirements for a Preserve Mirror operation are met. If the target specified is a Metro Mirror primary device, the pair is to go into a duplex pending state while the secondary device is updated with the tracks to be copied. PRESMIRNONE is the default if you specify FCTOPPRCPrimary without a subkeyword.

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:

Using FCTOPPRCPRIMARY might require RACF® authorization.
When FlashCopy is not used to perform the CONSOLIDATE operation, the FCTOPPRCPRIMARY keyword is ignored.
If you do not specify FCTOPPRCPRIMARY, or your storage subsystem does not support this capability, a PPRC primary volume cannot become a FlashCopy target volume.
When you use FCTOPPRCPRIMARY, the FlashCopy operation causes a PPRC primary volume to become a FlashCopy target volume. The PPRC-SYNC volume pair currently in full duplex state changes to a duplex pending state when the FlashCopy relationship is established. When PPRC completes the copy operation, the PPRC-SYNC volume pair changes to full duplex state.
