HiCommand Dynamic Link Manager User's Guide (for Windows(R))

2.8.4 When user operations change the intermittent error information

The following might be reset when the user changes the values set for an intermittent error or the path status: the number of errors that are counted during error monitoring, the time that has passed since error monitoring started, and the information about whether an intermittent error occurs (the path has been removed from those paths subject to automatic failback). Table 2-6 When user operations change the intermittent error information lists whether the above items are reset.

If you want to check whether intermittent error monitoring is being performed for the path, check the IEP item displayed when the dlnkmgr command's view -path operation is executed with the -iem parameter or the Intermittent Error Path item in the Path List view of the HDLM GUI. If a numerical value of 0 or greater is displayed in the Intermittent Error Path item, then intermittent error monitoring is being performed.

#1

When you change the intermittent error monitoring functionality to off, information about paths not subject to automatic failback will be reset. When you change the intermittent error monitoring functionality to off and you do not want to reset information about paths not subject to automatic failback, place the target paths Offline(C).

#2

The number of errors is reset to 0, and then monitoring restarts in accordance with the changed monitoring conditions.

#3

If the settings for a function other than intermittent error monitoring have been changed or the settings for intermittent error monitoring have not been changed, and then the Apply or OK button is clicked, the number of error occurrences and the time since monitoring started are reset. To leave the setting unchanged, close the Options window by clicking the Cancel button. If you want to change the settings for a function other than intermittent error monitoring but do not want to reset the intermittent error monitoring status, use an HDLM command.

#4

The number of errors is reset to 0, and then monitoring restarts.
