Cause. A protocol error occurred between the channel and device controller. The
controller sends a special handshake on the last byte transferred only during
anticipated odd-byte read transfers. A controller might have failed.
Effect. The data transfer in progress is aborted.
Recovery. If the error continues to occur, see Recovery Action Requiring Vendor
Support on page 3-13.
125: ZGIO-EVT-IIOPROTECTVIOLATION
A read data-transfer was made when the IO control (IOC) table indicated that only a
write data-transfer was allowed.
