Figure 5 The Physical Tab of the Auto LUN Window
When the Physical tab is active, the Auto LUN window contains the following items:
• When Monitoring Switch is Enable, Performance Monitor is monitoring the storage system (a
Disable setting indicates that the storage system is not being monitored).
• Gathering Interval indicates the interval of collecting statistics in short range monitoring. For
example, if the numbers of the CUs to be monitored are 64 or less, and 1 min. is displayed and
shortrange is selected as the storing period of statistics, the list and graph in the Physical tab
display the statistics obtained every one minute. In case 65 or more CUs are monitored, the
statistics are displayed every 5, 10 or 15 minutes.
Note: The gathering interval in long range monitoring is fixed to 15 minutes. If you select longrange
as the storing period of statistics, the list and graph display the statistics obtained every 15
minutes regardless of the value of Gathering Interval. For details on the storing period of statistics
(short range and long range), see “ Understanding Statistical Storage Ranges ” on page 15.
• In the drop-down list on the right of Monitoring Data, you can select the storing period of statistics
from shortrange and longrange (see Figure 6 on page 31).
Select which range of statistics you want to view in the window: statistics in long range or short
range.
