-iemnum number-of-times-error-is-to-occur
When the set -iem on operation is executed during error monitoring,
even though you do not change the conditions for intermittent error, the
number of errors and the time elapsed since the error monitoring starts
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
function 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.
Table 6-5 Relationship Between the Setting for the Automatic Failback
Function and Intermittent Error Monitoring and the Executable Operations

During intermittent error monitoring, if changes are made in the
settings of the intermittent error monitoring interval, the error count
and the elapsed time measured since monitoring starts are set to 0,
and monitoring starts by using the new settings.
Outside the duration of intermittent error monitoring, if changes are
made in the settings of the intermittent error monitoring interval, the
new settings take effect after the next time automatic failback
succeeds. 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 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.
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, the error count and the elapsed time
measured since monitoring starts are reset to 0, and monitoring starts
by using the new settings.
Outside the duration of intermittent error monitoring, if you change
the number of times that the error is to occur, the new settings take
effect after the next time automatic failback succeeds. 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.
