A PPRC CESTPAIR command was issued to devices in a PPRC pair state that does not support a conversion to the requested state. This can occur when a PPRC pair is in an active synchronous state and the CESTPAIR request changes the PPRC pair to an asynchronous state. To make this conversion, the active PPRC pair must first be suspended.
The command is rejected.
Verify the PPRC devices are in the correct state by using the CQUERY command. Suspend the pair, if necessary, make any required changes to the CESTPAIR specification, and reissue the CESTPAIR command.
