Why is the host agent record still displayed in the Host Information table (Monitoring+Array

remove the host agent record from the management station:
1. Click Monitoring+Array View in the left pane.

new configuration collection on the XP and P9000 disk arrays and also create, or configure the
following parameters again. For more information, see HP XP P9000 Performance Advisor Software

Why is UNIX host agent installing failing with JAVA not found error?
While installing a HP XP P9000 Performance Advisor UNIX host agent, the installation might fail
displaying the following error:
JAVA not found
The reason might be that the Path system variable on your host is not pointing to the location
where JRE is installed.
Complete the following steps to configure the Path system variable environment variable on your
host must point to the installed JRE location. To set the Java PATH, enter the following command
in the command prompt window:
export PATH=$PATH:/opt/java1.5/bin
You can verify whether the Path variable is updated by typing echo %path% in the command
prompt window. The output lists the paths that are set on your management station, and should
include %JAVA_HOME%\bin.
