7. If you want to display a graph to find out how the I/O rate has been
changed, take the following steps:
a. In the list, select one or more LUNs.
b. Click Draw.
Note: If the graph does not display changes in the I/O rate (for example, if
the line in the graph runs vertically), it is recommended that you change
the value in the Chart Y Axis Rate list. For example, if the largest value in
the list is 200 and the value in Chart Y Axis Rate is 100, you should
select a value larger than 200 from Chart Y Axis Rate.

Detail check box at the lower right of the list. The graph contents change

the graph displays changes in workload statistics about the item.
•
LUN: Indicates LUNs (logical unit numbers).
•
LDEV: Indicates IDs of volumes, in the following format: LDKC:CU:LDEV.
An ID ending in # indicates the volume is an external volume. An ID
ending in V or X indicates the volume is a virtual volume.
•
Emulation: Indicates emulation types.
•
Paths: Indicates the number of LU paths (i.e., paths to volumes).
•
Current: Indicates the current I/O rate.
•
Ave.: Indicates the average I/O rate for the specified period.
•
Max.: Indicates the maximum I/O rate for the specified period.
