3. Select the check box for the metric, for which you want to view the performance graph of the
selected components and click OK.
P9000 Performance Advisor plots appropriate performance graphs in the Chart Work Area. By
default, the data points are plotted for the last one hour of the management station's time. For
more information on using charts and chart options, see Plotting charts.
NOTE:
When you plot the average read or write response graph for an LDEV, P9000 Performance Advisor
also displays a table that provides the duration and the corresponding date when the load was high
on the LDEV.

Example troubleshooting scenarios
The following are the example use cases for understanding troubleshooting functionality:
Application has 3 LDEVs from XP mapped to it through two different ports (1A and 5A). There is one
CLPR (CLPR10) that hosts these LDEVs:
• LDEV 1: RG 1-1: RAID1 (2D+2D)
• LDEV 2: RG 1-2: RAID5 (3D+1D)
• LDEV 3: RG 2-1, 2-2: RAID5 (14D+2P)
Issue 1
High utilization of CHA MP on port 5A causing response time to increase for all LDEVs associated
with the application. The MP in question manages another port (7A) whose IOPS are high in number
causing the MP utilization to go up. Port 7A does not have any LDEVs mapped to the host in question.
Steps for troubleshooting:
1. Launch P9000 Performance Advisor.
2. Navigate to the troubleshooting screen.
