LDEV Activity report

You can view the maximum and least busiest LDEVs in an XP or an XP7 disk array through the LDEV
Activity report. The LDEV data can be for one of the following metric types:
• FontEndIO
• BackEndIO
• MB
• Utilization
• Read Response Time
• Write Response Time
The maximum and least busiest LDEVs are collated based on the maximum and minimum threshold
levels you specify, and also the metric type that you select. For the metric type and duration that you
specify, the average of the total performance of each LDEV is considered. Further, the average value is
verified with the set threshold levels to see if that particular LDEV's performance is above or below the
threshold limit. Based on their average values, the LDEVs are grouped in the top 100 busiest or the least
100 busiest LDEVs, and displayed in the CSV file. It implies that only those LDEVs that are above the
maximum and below the minimum set threshold limits are considered.
