6. Command Reference
422
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 error monitoring has
