the center of the chart.

LDEV IO report

The LDEV IO report provides data on the busiest frontend and the backend LDEVs and RAID Groups on
an XP or an XP7 disk array. It is based on the frontend I/Os and the backend transfers. You can view the
report for 8 - 128 busiest frontend and backend LDEVs, and 8 - 32 busiest frontend and backend RAID
Groups. The selection is in multiples of eight.
If you do not select any value from the respective drop-down lists, by default, the LDEV IO report is
generated for the eight busiest frontend and eight backend LDEVs, and eight frontend and eight backend
RAID Groups. Further, the report displays the graphs for only those LDEVs that have the associated I/Os
and those RAID Groups on which the I/Os transactions have occurred.
Consider the following example: A report is created to view 32 busiest frontend LDEVs and 16 busiest
frontend RAID Groups, and only eight of the selected 32 LDEVs and four of the selected 16 RAID Groups
are busy. PA generates the LDEV IO report where you can view the graphs for only the eight LDEVs and
four RAID Groups on which the maximum I/O transactions have occurred. The graphs are not shown for
the remaining LDEVs or the RAID Groups. The LDEV IO report also provides a link to the additional
LDEV IO mapping information. The busiest LDEVs are displayed at different ranks in a tabular format.
