Outside the duration of intermittent error monitoring, if you change the number of times
that the error is to occur in order for the system to determine that an intermittent error has
occurred, from the next time automatic failback finishes normally, the changed values takes
effect. Outside the duration of intermittent error monitoring, the number of errors that
determine an intermittent error is not counted and this value is not changed.
The number of times that the error is to occur specified in this parameter is stored even
though specifying -iem off disables intermittent error monitoring. Therefore, when you
re-enable intermittent error monitoring and the number of times is not specified, the error
monitoring will be executed using the stored number of times.
When the set -iem on operation is executed during error monitoring, even if you do not
change the conditions for intermittent error, the number of errors and the time that has
passed since the error monitoring starts are reset to 0. Then intermittent error monitoring
resumes with the changed settings.
If you set automatic failback to off while intermittent error monitoring is on, intermittent
error monitoring becomes disabled. Note, however, that if you use the view -sys
operation to display the HDLM functionality configuration, Intermittent Error Monitor
shows on. When automatic failback is returned to on, intermittent error monitoring
becomes enabled.
The executable operations for automatic failback and intermittent error monitoring depend
on the setting status for those functions.
Table 7.5 shows the relationship between the setting status for automatic failback and
intermittent error monitoring and the executable operations for those functions.
