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 “Array View LDEV table
- Sort By options” (page 216).
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.
Configuring column settings
You can view data for various components in the LDEV table. The data displayed varies based
on whether you selected an XP or an XP7 disk array. By default, HP XP7 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 P9500/XP7 disk arrays columns
indicate whether that particular component is displayed for the XP/P9500/XP7 disk array.
