When A User Changes The Intermittent Error Information - Hitachi XP P9500 User Manual

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 on page 2-19 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.

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 2-20 lists whether the
above items are reset.
If you want to check whether intermittent error monitoring is being
performed for the path, check the IEP item displayed when the dlnkmgr
command's view -path operation is executed with the -iem parameter. If a
numerical value of 0 or greater is displayed in the above items, then
intermittent error monitoring is being performed.
