HP XP Array Manager Software - Manual (Page 64)

NOTE:
• The list displays up to a maximum of 4,096 resources at a time. If the number of resources
exceeds 4,096, use Previous and Next to display the remaining resources.
• If you change the date and time in the From and To boxes and then click the Apply button,
Performance Monitor recalculates usage rates and updates information in the list. To change
the date and time in From and To boxes, use the arrow buttons and the sliders (for details,
see “
Auto LUN Window, Physical Tab ” on page 31).
• If an exclamation mark (!) is displayed before a usage rate, the reported volume usage rate
is likely to be inaccurate, because the configuration has changed (for example, volumes have
been moved by XP Auto LUN or XP Business Copy, or formatted by Virtual LVI or Open
Volume Management).
For more information on using XP Auto LUN, see the
HP StorageWorks XP24000/XP20000
Auto LUN Software User Guide.
• If a plus mark (+) is displayed before a usage rate 0, such as +0, the usage rate is not com-
pletely 0 but less than 1.
6. To display a graph that illustrates changes in usage rate for volumes, select the desired volumes
in the list and then click the Draw.
NOTE:
The range of monitoring and the gathering interval affects the time period represented by a
graduation on the horizontal axis.
