Zaromil, Are you using the BCM (Business Continuity Manager) Host software, or the archaic PPRC commands?
PPRC commands are designed for PPRC, but there are a few features we have managed to kludge into it. Most of the enhancements to TrueCopy and Shadowimage over the last three years are enabled through BCM.
