HP XP P9000 Performance Advisor Software - Manual (Page 328)

•
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 HP XP 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.
To start troubleshooting performance issues of components that are associated with an application:
1.
Click Troubleshooting+Host Based in the left pane.
The list of the XP and the P9000 disk arrays monitored by HP XP P9000 Performance Advisor
are displayed in the component selection tree under Host Based.
2. Select the XP or the P9000 disk array for which you want to associate an application.
3. Click Configure Application.
The Configure Application dialog box appears.
4. Click Add.
5. Do one of the following:
•
Click the Host Groups option and choose the host group from the list. The host groups
for hosts communicating with the selected disk array are listed.
•
Click the WWN option and choose the WWN from the list. The WWNs for hosts
communicating with the selected disk array are listed.
6. Click New under Application and provide the application name. If you want to associate an
existing application with the selected host group or WWN, click Existing under Application
Name and choose the application from the list. There may be instances where the LDEVs
associated with an application are made available through two hosts that belong to different
WWNs or host groups. In such cases, you may want to associate the application with both
the hosts. There may be cases where the same set of LDEVs are made available through one
host to two different applications. In such cases, you may want to associate the host with both
the applications.
Initially, when HP XP P9000 Performance Advisor is first installed, the Existing list does not
display any application entries, as the association is not yet configured.
