(3) When the Conditions for an Intermittent Error Are Changed During Error
Monitoring
When the conditions for an intermittent error are changed during error monitoring, the
number of errors and the amount of time that has passed since the error monitoring
started are both reset to 0. As such, the error monitoring will not finish, and it will start
over by using the new conditions.
If the conditions are changed while error monitoring is not being performed, error
monitoring will start up again and use the updated conditions after any given path is
recovered from an error by performing an automatic failback.
Figure 2-12: What Will Happen When Conditions Are Changed During Error
Monitoring shows what will happen when the conditions for an intermittent error are
changed during error monitoring. For this example, the conditions have been changed
from 3 or more errors in 30 minutes, to 3 or more errors in 40 minutes. The events that
occur are described by using the time arrows.

2.9.4 When a User Changes the Intermittent Error Information
The following might be reset when a user changes any of the values set for the
intermittent error or the path status: the number of errors that have already been
counted during error monitoring, the amount of time that has passed since error
monitoring has started, and the information about whether an intermittent error has
occurred. Table 2-5: When Effects of a User Changing the Intermittent Error
Information lists whether the above items are reset.
