Enables you to view statistics about trafﬁc at path between host bus adapters (HBAs) and ports

(see “Trafﬁc between HBAs and Storage System Ports” on page).

Two sliders are displayed on the upper right of the Auto LUN window. To the left and right of the two

sliders, dates and times are displayed. The term between these dates and times is the period in which

statistics are stored. If the date and time on the left is 2007/03/27 16:00 and the date and time on the

right is 2007/03/28 16:00, you can view usage statistics for the period of 2007/03/27 16:00 to

2007/03/28 16:00.

If you change the dates and times in the From and To boxes, you can specify the range of statistics that

should be displayed in the window. For example, if the window displays statistics for the last one month,

you can change the values in the From and To boxes to display the statistics for the last week only or to

display the statistics for the last three days only.

When monitoring ports, LU paths or host bus adapters in the Port-LUN tab or the WWN tab, you can

view the monitoring results in near-real time. To view the monitoring results in real time, select the Real

Time option which is included in the Monitoring Term area of the Auto LUN window. The information in

the window will be updated at the speciﬁed gathering interval (every 1 to 15 minutes). Note that you

cannot view the monitoring results displayed in the Physical tab and the LDEV tab in real time.
