Intermittent Error Monitoring Actions
Intermittent error monitoring is performed on each path, and it automatically
starts as soon as a path is recovered from an error by using the automatic
failback function.
This subsection describes the following intermittent error monitoring actions:
•
When an intermittent error occurs
•
When an intermittent error does not occur
•
When the conditions for an intermittent error to occur are changed during
error monitoring
When an Intermittent Error Occurs
When an error occurs on a path a specified number of times within a specified
interval, the error monitoring will finish and the path is determined to have
an intermittent error, upon which the path is removed from those subject to
automatic failbacks. The path that is removed will remain in the error status
until the online operation is performed.

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.
