3. Sort the LDEV data based on one of the options displayed in the Sort By list. By default, the LDEV
data is sorted based on the average read response and displayed in a descending order in the
LDEV table. For more information on the attributes, see Table 13 on page 240.
Before clicking the Query button, you can also select the attribute from the Sort By list. The LDEV
data is automatically sorted based on the selected attribute and displayed in the LDEV table. The
sorting is uniform across all the records displayed in the LDEV table and not limited to the current
section of records that you are viewing in the LDEV table.

You can view data for various components in the LDEV table. The data displayed varies based on
whether you selected an XP or a P9000 disk array. By default, P9000 Performance Advisor displays
data for the following components based on the array you select. The data displayed is for the last
collection cycle or the selected date and time range.
The following table provides the components for which you can view the data in the LDEV table by
default. The Yes and No given under For XP disk arrays and For P9000 disk arrays columns indicate
whether that particular component is displayed for the XP or the P9000 disk array.
