The values specified from the last time are used.
The following shows the sub-parameters that should be specified: the
error monitoring interval and the number of times that the error is to
occur:
-intvl error-monitoring-interval
Specify the monitoring interval for an intermittent error. Use a value
from 1 to 1440 minutes. The default is 30.
During intermittent error monitoring, if changes are made to the
intermittent error monitoring interval setting or the setting for the
number of times that an error is to occur, the error count and the
elapsed time measured since monitoring has started are reset to 0.
When intermittent error monitoring is not being performed, if changes
are made in the settings of the intermittent error monitoring interval
or the number of times that an error is to occur, the new settings will
take effect after the next time an automatic failback is successful.
Because the errors and elapsed time are not counted or measured
while intermittent errors are not being monitored, the values will not
change.
The monitoring interval specified in this parameter is stored even
though specifying -iem off disables intermittent error monitoring.
Therefore, when you re-enable intermittent error monitoring and a
monitoring interval is not specified, error monitoring will be performed
by using the stored monitoring interval.
-iemnum number-of-times-error-is-to-occur
Specify the number of times the error is to occur. Valid values are
from 1 to 99. The default is 3.
During 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, the number of errors and the
time that has passed since intermittent error monitoring has started
are reset to 0. The changed setting will take effect immediately and
intermittent error monitoring will restart. When intermittent error
monitoring is not being performed, 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, the new value will take effect after
the next automatic failback successfully completes. When intermittent
error monitoring is not being performed, the number of errors that
determine that an intermittent error has occurred is not counted and
this value is not changed.
The number of times that the error is to occur is stored in the system,
even when -iem off is specified and intermittent error monitoring is
disabled. Therefore, when you re-enable intermittent error monitoring
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 though you do not change the conditions for intermittent error
monitoring,the number of errors and the time that has passed since the
