Cause. The channel tried to interrogate a requesting device controller during data
transfer, but the device controller responded with a command word that did not indicate
the direction of the data transfer. The device controller probably failed.
Effect. The requested operation is not performed.
Recovery. If the error continues to occur, see Recovery Action Requiring Vendor
Support on page 3-13.
111: ZGIO-EVT-IIOBUSPARITY
A parity error occurred during a data transfer between the channel and device
controller over the input/output bus.
