Viewing 10 busiest LDEVs and RAID groups
To view the 10 busiest LDEVs and RAID groups associated with an XP or a P9000 disk array's backend
activities, click BackEndIO in the component selection tree for the XP or the P9000 disk array. The
top 10 busiest LDEVs are displayed under the LDEV tab and the top 10 busiest RAID groups are
displayed under the RG (RAID Group) tab. This data is also displayed when you click the Backend
Total Avg group box under the Performance View tab.
If the number of busiest LDEVs or RAID groups are less than ten or if their utilization is zero, only the
busiest components are displayed. The 10 busiest LDEVs selected is based on the backend transfer
rate and the 10 busiest RAID groups selected is based on the Overall % RAID Group Utilization.
