Figure 2-11 Action What Will Happen When an Intermittent Error Occurs
on a Path
When an Intermittent Error Does Not Occur
If an error does not occur in the path the specified number of times within
the specified interval, the system determines that the path does not have an
intermittent error. In such a case, the error monitoring will finish when the
specified error-monitoring interval finishes, upon which the number of errors
is reset to 0. If an error occurs on the path again at a later time, error
monitoring will resume when the path is recovered from the error via an
automatic failback.
If it takes a long time for an error to occur, an intermittent error can be more
easily detected by increasing the error-monitoring interval or by decreasing
the number of times that the error needs to occur.
The figure below shows the action taken when an intermittent error is
assumed not to have occurred on the path. For this example, the path is
determined to have an intermittent error if the error occurs three or more
times in 30 minutes. The events that occur are described by using the time
arrows.
