(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 2-14: 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.

occurred. Table 2-7: When Effects of a User Changing the Intermittent Error

Information lists whether the above items are reset.
