HP XC System Software Installation Guide Version 3.2

5.4 Task 3: Install the Upgrade RPM and Prepare the System
Follow this procedure to install the upgrade Red Hat Package Manager (RPM), and run the
preupgradesys script, which performs the necessary preprocessing to prepare the system:
1. Insert the HP XC System Software Version 3.2 DVD into the DVD drive on the head node.
2. Create the following directory:
# mkdir /mnt/cdrom
3. Mount the DVD on /mnt/cdrom:
# mount /dev/cdrom /mnt/cdrom
4. Change to the following directory:
# cd /mnt/cdrom/HPC/RPMS
5. Find the name of the hptc-upgrade RPM:
# ls hptc-upgrade*
hptc-upgrade-1-n.noarch.rpm
In the previous example, n in the RPM name represents the RPM version number. The
version number varies from release to release.
6. Install the RPM:
# rpm -Uvh hptc-upgrade-1-n.noarch.rpm
7. Return to the home directory:
# cd
8. Prepare the system for the upgrade:
# preupgradesys
The preupgradesys utility performs all the necessary
pre-processing steps needed to upgrade your cluster. This script
must be run before you upgrade your system.

The command output looks different depending upon the head node hardware model and
the interconnect type.
CAUTION: Do not proceed to the next step in the upgrade process if the output from the
preupgradesys script indicates failures. If you cannot determine how to resolve these
errors, contact the HP XC Support team at the following e-mail address:

9. Save the current system configuration to a file to create a snapshot of the system configuration
before the upgrade:
# shownode config --admin > /var/log/preupgradesys/shownode_config.txt
Proceed to “Task 4: Upgrade Linux and HP XC RPMs.”
5.5 Task 4: Upgrade Linux and HP XC RPMs
The upgrade processes uses YUM to determine RPM dependencies. YUM updates, installs, and
removes RPMs from the system accordingly.
