When An Intermittent Error Does Not Occur - Hitachi XP P9500 User Manual

Figure 2-10 Action What Will Happen When an Intermittent Error Occurs on a
Path on page 2-23 shows what will happen when an intermittent error
occurs. For this example, the path is determined to have an intermittent error
when the error occurs 3 or more times within 30 minutes. The events that
occur are described by using the time arrows.

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.
Figure 2-11 What Will Happen When an Intermittent Error Does Not Occur on
a Path on page 2-24 shows what will happen when an intermittent error
does not occur. 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.
