HP XP7 Performance Advisor v6.1 Software Troubleshooting and FAQs Guide

1. After the upgrade, download the host agents from the Support screen of HP XP7 Performance
Advisor and upgrade them on the respective hosts.
For a Linux host agent, remove the existing version of the host agent software from the Linux
hosts pointing to the management station before upgrading the management station version.
NOTE: Check the required version of RMLIB is installed.
2. Perform one round of configuration and then the performance data collections for the disk
arrays connected to these host agents.
3. Verify if the host agents are appearing in the Host Information table in HP XP7 Performance
Advisor. Ensure that software versions of HP XP7 Performance Advisor management station
and the host agent are the same.
Cause
An incorrect port number is specified for HP XP7 Performance Advisor and host agent
communication. In such a case, the installation process completes but the Connection refused
error message appears when the host agent tries to establish connection with HP XP7 Performance
Advisor.
Resolution
Verifying the HP XP7 Performance Advisor Tomcat service.
Manually verify if the HP XP7 Performance Advisor Tomcat service is active on the management
station. If the service has stopped, try to restart the service by following these steps:
1. Select Start ⇒ Run and type services.msc.
The Services dialog box appears.
2. Right-click HP XP7 Performance Advisor Tomcat service and select Start from the drop-down
list.
If you have configured the HP XP7 Performance Advisor Monitor service to automatically restart
the Tomcat service, it tries to restart the Tomcat service for the retry count you specified in the
PAMonitor_mail.properties file available in the <Install_drive>:\HPSS\paMonitor\
conf folder on your management station. Then, it sends an email notification that describes whether
the restart Tomcat service was a success or a failure. For more information on configuring the HP
XP7 Performance Advisor Monitor service to restart the Tomcat service, see the HP XP7 Performance
Advisor Software User Guide.
Specify the correct HTTP port number of the management station in the paxp_service.properties
file.
On the management station, manually replace the existing port number:
1. Look for the following tag in the server.xml and manually replace the existing port number
with the new port number:
<Connector port="Existing_port_num" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="443"/>
The server.xml is available in the <Installation_Drive>:\HPSS\pa\tomcat\conf
folder on your management station.
2. Restart the HP XP7 Performance Advisor Tomcat service.
On the host agent, manually update the new port number of the management station:
1. On a Windows host, open the paxp_service.properties file from the
<Installation_Drive>:\Program Files\Hewlett-Packard\xppa\hostagent\
config folder on your host system. If it is a custom install location, the file is available in the
<Installation_Drive>:\<Installation_Directory>\hostagent\config folder.
On a UNIX host, open the paxp_service.properties file from the
<Installation_Drive>:\opt\xppa\hostagent\config folder.
