Cevice not operational.
(I/O operation requested on a tape drive not attached to I/O
channel)
1 0702 Hardware malfunction.
1 Tape I/O operation resulted in interface control check or
1 channel data check. The checks are caused by a channel or
1 control unit malfunction, which shculd not occur during normal
I operation. An interface control check can occur at the time
1 an XIO instruction is executed or at interruFt time. A chan-
I nel data check can occur only during the execution of an XIO
1 instruction. In both cases, the xro instruction may have been
I issued as a result of a request for 1/0 either in the problem
I program or within the error recovery routine in the Basic
I Monitor.
.. -------+-
0703 Channel programming error.
The physical tape I/O and error routines attempted to execute
an invalid command or command chain. The cOIresponding XIe
instruction may have been issued as a result of a request for
I/G either in the problem program or in the error recovery
routine.
The halt is caused by one of the following conditions:
a) The device address in the specified physical unit block is
zero;
b) the command code in the CCW has four low-order zero bits;
c) the length count of a read, read-backward, write, or sense
command is zero;
d) the ccw contains an invalid data address (protected area
or outside available storage), or the data address becomes
invalid at a point during the execution of a read, read-
backward, write, or sense command (i.e., while data is
being transferred);;
e) the command chain begins with a transfer-in-channel com-
mand
or has tvo successive transfer-in-channel commands.
