Hitachi Dynamic Link Manager Software Users Guide for Windows (7.6)

without specifying the number of times, the error monitoring will be
executed using the value stored in the system.
When the set -iem on operation is executed during error monitoring,
even if you do not change the conditions for intermittent error
monitoring, the number of errors and the time that has passed since the
error monitoring has started are reset to 0. Intermittent error monitoring
will then resume with the changed settings.
If you set the automatic failback function to off while intermittent error
monitoring is on, intermittent error monitoring will be disabled. Note,
however, that if you use the view -sys operation to display the HDLM
functionality configuration, Intermittent Error Monitor will be shown as
on. When the automatic failback function is returned to on, intermittent
error monitoring will once again be enabled.
The executable operations for the automatic failback function and
intermittent error monitoring depend on the settings for those functions.
The table below shows the relationship between the settings and available
operations for automatic failback and intermittent error monitoring.

Set AFB to on. The operations of AFB and IEM do not
change.
Change the AFB setting. AFB is performed under the new
settings.
#1
Set AFB to off. • AFB and IEM are disabled.
• The error count, elapsed monitoring
time, and information about paths
not subject to automatic failback are
cleared.
Set IEM to on. • When a path is being monitored
(during a period of conditional
intermittent error monitoring), the
value of the error count and the
elapsed monitoring time are reset to
0, and then intermittent error
monitoring will restart.
• When a path is not being monitored,
nothing changes.
Change the IEM settings. • While a path is being monitored, the
value of the error count and the
elapsed monitoring time are reset to
0, and then intermittent error
monitoring will restart.
