HP StorageWorks XP Performance Advisor Software v4.6 Install Guide (T1789-96096, July 2010)

On a UNIX host, look for the host agent version displayed in the PerformanceAdvisor.log
file. This file is located in the /opt/xppa/hostagent/log folder.
If you have logged into XP Performance Advisor, the host agent version is also displayed in the
Host Information table under HA Version. For more information, see “Requesting host up-
date” on page 97.
If the host agent version is different, you can upgrade the existing host agent version to be in sync
with the version of XP Performance Advisor installed on your management station. For more inform-
ation, see “Upgrading to the latest versions of host agents” on page 95.
After the issue is resolved and you are able to view the host agent records, refresh the Host Information
table on the Array View screen. For more information, see “Using XP Performance Advisor” on page 97.
You can also see the chapter on communicating with hosts in the HP StorageWorks XP Performance
Advisor Software User Guide. For document download location, see “Related
documentation” on page 126.
XP Performance Advisor is not collecting data after install or upgrade
XP Performance Advisor might not collect configuration or performance data for XP disk arrays though
the installation, or upgrade completed without any errors.
Following are the typical causes:
• The Command device is not created or presented to your host (probability of occurrence is higher
with installations)
• The Windows firewall is configured
• The Java heap size is not set or set with incorrect values
• The available disk space on your management station is low
• The upgrade log file, xpslperf_UpgradeScript.log is created (with errors), or has not been
created (occurrence is only with upgrades)
• The Std*out.log file increases in size
• The JRE versions installed on the management station and host are the same
• Check that the GUID is created properly, if it is on a Windows host (probability of occurrence is
higher with installations)
• User level understanding on how to collect configuration and performance data
