2.5 Upgrading HP Insight CMU
Complete the steps in this section if you are upgrading an existing HP Insight CMU system from a
previous HP Insight CMU version.
2.5.1 Dependencies
2.5.1.1 64-bit versions on management node
As of V7.0, HP Insight CMU is an x86 64-bit kit only and can no longer run on x86 32-bit hardware.
Previous releases required libX11, libxdmcp, and libXau on the management node only. These
requirements are still valid, but only 64-bit versions must be used. That is, at upgrade time HP
Insight CMU V7.0 and later might require libX* packages again, in their 64-bit versions (x86_64
in the rpm names).
2.5.1.2 tftp client
As of V7.0, HP Insight CMU depends on /usr/bin/tftp on the management node because of
sanity check improvements.
2.5.1.3 Java version dependency
HP Insight CMU v7.1 depends on Oracle Java version 1.6 update 26 or later. HP strongly
recommends upgrading the Java JVMs on both the management node and the endstations running
the GUI to version 1.6u26 or later to avoid security problems with the remote file browser (used
by the cmu_pdcp and autoinstall GUI dialogs).
2.5.1.4 Monitoring clients
Upgrading the management node to HP Insight CMU v7.1 also requires upgrading the monitoring
clients to v7.1 on the compute nodes. Monitoring will fail with an HP Insight CMU v7.1 management
node and v7.0 or previous compute node clients.
2.5.2 Stopping the HP Insight CMU service
To stop the HP Insight CMU service on the management node:
# /etc/init.d/cmu stop
2.5.3 Upgrading Java Runtime Environment
If you are upgrading from HP Insight CMU v5.x or v7.0, Java Runtime Environment V1.6u26 or
later is required for HP Insight CMU v7.1. For more information about downloading the Java
Runtime Environment, see
“Java installation” (page 132) . For more information about setting the
Java PATH, see “Setting the Java PATH” (page 133) .
2.5.4 Removing the previous HP Insight CMU package
To remove the previous HP Insight CMU package:
# rpm –e cmu
The following message appears:
configuration saved into /opt/cmu/etc/savedConfig/cmuconf##.sav
Save this information. After installation, use this information to restore the previous configuration.
# /opt/cmu/tools/restoreConfig /opt/cmu/etc/savedConfig/cmuconf##.sav
