A PPRC Establish request was issued with the INCRESYNC(START) keyword. The change recording mechanism is already active for the specified source device. This might be because the specified primary is a FlashCopy® source, established with the INCREMENTAL(YES) keyword.
The command is rejected.
If the incremental resync change recording mechanism is required for the PPRC pair and the device is a FlashCopy source, issue a FlashCopy Withdraw command for the incremental relationship and reissue the Establish Pair command. If the incremental resync change recording mechanism is not required for the PPRC pair, reissue the request without INCRESYNC(START).
Peer-To-Peer Remote Copy (PPRC).
