HP Matrix Operating Environment 7.2 Getting Started Guide

4 Troubleshooting
This chapter describes some of the tools and procedures that can be used to troubleshoot problems
in Matrix Operating Environment. Additional troubleshooting information can be found in the user
guides listed in “Using Matrix OE and related environments” (page 45). For information about
known issues and workarounds in this release, see the HP Matrix Operating Environment Release
Notes.
Memory and other system requirements
Make sure that your CMS and managed systems meet the requirements specified in the HP Insight
Management Support Matrix. In particular, note the recommended and minimum supported memory
requirements. This document is available at http://www.hp.com/go/matrixoe/docs.
If error messages about exceeding heap space are displayed, you may need to increase the heap
size of the Systems Insight Manager Java Virtual Machine (JVM). On 64–bit systems, Systems
Insight Manager sets the heap size to 4096 MB (4 GB). You can specify a different heap size by
setting the JVMMAXHEAP value (in MB) in the globalsettings.props file. On HP-UX, this file
is at /etc/opt/mx/config/globalsettings.props. On Windows, it is at
installation-directory\config\globalsettings.props. The default installation
directory is C:\Program Files\HP\Virtual Server Environment, but this directory can
be changed at installation time.
Insight managed system setup wizard
Many configuration issues can be avoided by using the managed system setup wizard to configure
managed systems for use with Matrix OE. The wizard automates the installation of required licenses,
agent software, and other configuration settings to support the management capabilities intended
for use on the system.
To start the managed system setup wizard, select Configure→Managed System Setup Wizard...
from the top menu. Help is available in each step of the wizard.
Diagnose menu actions
There are three tasks available from the Diagnose→Troubleshoot Matrix Operating Environment
menu, described in the following sections. These tasks use the vseassist command to perform
configuration checks. For examples of the output from these checks, see vseassist(1M) (page 52).
Check CMS configuration
This task performs a number of configuration checks on the CMS. When troubleshooting your
configuration, perform this task first. Once you have resolved any CMS configuration issues, you
can diagnose issues with specific managed systems using the “Check CMS to managed node
communication” (page 40) and “Check managed node configuration” (page 41) tasks described
below.
Procedure 9 Check the configuration of your CMS
1. From the top menu bar, select Diagnose→Troubleshoot Matrix Operating Environment→Check
CMS Configuration....
2. To schedule this task to run periodically or at a set time, click Schedule. The Schedule Task
screen is displayed. Help on scheduling options is available from that screen. After the task
executes, you can view the results by selecting Tasks & Logs→View Task Results... from the
top menu bar.
To run this task immediately, click Run Now. This executes the vseassist command on the
CMS and displays the results in the Stdout tab.
