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.
The figure below shows the action taken when the conditions for an
intermittent error are changed during intermittent 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.
Figure 2-15 What Will Happen When Conditions Are Changed During Error
Monitoring
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 2-6 When Effects of a User
Changing the Intermittent Error Information on page 2-30 lists whether the
above items are reset.
If you want to check whether intermittent error monitoring is being used for a
path, check the IEP item displayed when the dlnkmgr command's view -path
operation is executed with the -iem parameter specified, or the Intermittent
Error Path item specified in the Path List view of the HDLM GUI. If 0 or
greater is displayed in the Intermittent Error Path item, then intermittent
error monitoring is being performed.
