HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

2. Based on your requirement, select an application or choose the host or the WWN associated
with an application:
If your selection is at the application level, the data displayed for the LDEVs and the associated
components is through all the hosts and the WWNs associated with the application. Hence, the
data is a superset of the data that you view at the host or the WWN level.
• To select a host, click the + sign for an application and select the host from the list of hosts.
If your selection is at the host level, the data displayed for the LDEVs and the associated
components is through all the WWNs that belong to the selected host.
• To select a WWN, click the + sign for an application, select the host, and choose the WWN
from the list of WWNs.
If your selection is at the WWN level, the data displayed for the LDEVs and the associated
components is only through the selected WWN.
The Troubleshooting screen displays the associated LDEVs, ports, RAID groups (including pool
ID), and the CLPRs performance data in the respective tables. The levels at which the information
is retrieved is also displayed at the top of the screen. For example, if you are viewing details for
an application through a specific host, the following path is displayed for your reference:
<Array_ID> > Application <name> > Host <name>.
If you have set the duration for which P9000 Performance Advisor must analyze and show the
variation in the average read and write response of LDEVs, the following message appears on
the Troubleshooting screen: P9000 Performance Advisor is analyzing the Average
Read/Write Response time for the LDEVs. This may take some time. Please
wait...
The time taken to analyze and display the average read and write response values for the LDEVs
on the Troubleshooting screen is directly proportional to the duration that you set. For more
information on setting the duration, see “Setting the duration to predict the LDEV response
time” on page 100.
“Troubleshooting screen” on page 357 shows the troubleshooting screen displayed for 53036,
which belongs to the P9500 Disk Array type.
