4Q27I SHDNOT
Cause: A QTAM line I/O interrupt has occurred with CSW status or sense data invalid for the
hardware involved. QTAM checks for error-free status and for all valid error conditions; if the
actual ending conditions do not match any of these, this error message is written. This is
probably a hardware error.
System Action: Normal QTAM operation continues.
Programmer Action: none.
Operator Action: If the_ problem persists, have the
· system log showing this error message
· PDAIDS I/O trace to record the sequence of interrupts preceding the problem
· ROD command output
· EREP output (see DOS/VS SADP)
available for problem determination.
