3.
View the performance data of the disk array components.
If you application is using XP disk array components, view the performance data of LDEVs, ports,
CLPRs, RAID groups, and the usage data of CHAs and DKAs.
If your application is using P9000 disk array components, you can view the usage data of the
MP blades in addition to viewing the performance data of LDEVs, ports, CLPRs, and RAID groups.
The data can be viewed at the application level and host group or WWN level. For more
information, see “
Viewing performance or usage data for components
4.
Plot graphs to analyze the performance or the usage of individual components that are associated
with the application. For more information, see “
Associating applications with hosts
You can associate an application with a host using the host group or WWN of the host.
Prerequisites
Ensure that the following prerequisites are met before associating an application with the hosts:
•
Know the application for which you want to troubleshoot the associated LDEVs performance.
•
Know the XP and the P9000 disk arrays that have LDEVs associated with your application.
•
Know the host where your application resides.
•
Know the WWNs for the hosts.
Run the XPInfo command at the command prompt of the host where your application resides.
The HBA Port WWN in the P9000Info output provides the WWN number. If your host does not
have P9000Info, download the executable from the Support screen in P9000 Performance Advisor
(click Support on the Dashboard screen) and install on the host.
•
Ensure that the configuration data collection is complete and the performance data collection is
in progress for the XP and the P9000 disk arrays.
IMPORTANT:
•
Your application can be associated with LDEVs that are made available through different hosts
and WWNs.
•
There is no limit on the number of applications that you can associate with hosts and WWNs.
•
An application cannot be associated with a WWN communicating with an XP or P9000 disk array
for which configuration data is collected using the Outband mode.
