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, the 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 change 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.
When you upgrade from HDLM 03-00 or 03-01 to 05-00 or later:
When you upgrade to HDLM 05-00 or later from HDLM 03-00 or 03-01, and
the
-pchk
parameter was already set to
on
in the previous version, the
-afb
parameter will be set to
on
in the new version. The value of the
-intvl
parameter will be set to the same value as the previous checking interval of
the
-pchk
parameter.

Enables or disables intermittent error monitoring.

: Disabled
Intermittent error monitoring can be enabled only when automatic failback is set
to
on
.
When you use automatic failback, we recommend that you set intermittent error
monitoring to
on
to prevent an intermittent error from reducing I/O performance.
If
on
is specified, be sure to also specify the intermittent error monitoring interval
and the number of times that the error is to occur. The system assumes that an
intermittent error is occurring if the specified number of times that the error is to
