See

Table 6-5 Relationship Between the Setting for the Automatic

Failback Function and Intermittent Error Monitoring and the Executable

Operations on page 6-27

for the relationship between automatic

failbacks and intermittent error monitoring.
When you specify on, specify the checking interval by specifying the

parameter immediately following on. If you do not specify a checking

interval, path statuses will be checked in the following way:

¢

When the checking interval has not been specified before:
Every 60 minute (default setting)

¢

When the checking interval has been specified before:
The previously used interval

The explanation for the following sub-parameter describes how to specify

the interval between path status checks.

-intvl checking-interval

Specify the interval between path status checks. Specify a value from

1 to 1440 minutes. The default is 60. Specify an interval appropriate

for your operating environment.
If intermittent error monitoring is on and the number of times that the

error is to occur is set to a value of 2 or more, the following condition

must be satisfied:

error-monitoring-interval >= checking-interval-for-automatic-

failback × number-of-times-error-is-to-occur-during-

intermittent-error-monitoring

If this condition is not satisfied, the KAPL01080-W message will be

output and an error will occur. If this happens, change any of the

following settings: the checking interval for automatic failbacks,

intermittent error-monitoring interval, or the number of times that the

error is to occur.
When you set the number of times that the error is to occur to 1, the

above condition does not need to be satisfied.
When you changed the error monitor interval while intermittent error

monitoring is running, the new settings will take effect immediately.

When the checking interval is shortened and the checking interval

time after the change has already elapsed during the current checking

interval, the path status check will start over.
This setting remains stored in the system, even if you disable the

function by changing the setting of automatic failbacks to off.

Therefore, if you re-enable automatic failbacks and do not change the

interval, path status checks will be executed at the interval already

stored in the system.

-iem { on [-intvl error-monitoring-interval] [-iemnum number-of-times-

error-is-to-occur] | off }

Enables or disables intermittent error monitoring.
on: Enabled
off: Disabled
