Task 2: Install the Upgrade RPM and Prepare Your System
Perform the following procedure to install the upgrade Red Hat Package Manager (RPM®), and run the
preupgradesys script, which performs the necessary preprocessing to prepare your system:
1. Insert the HP XC System Software Version 3.0 DVD into the DVD drive on the head node.
2. Mount the DVD at the following location:
# mount /dev/cdrom /mnt/cdrom
3. Change to the following directory
# cd /mnt/cdrom/HPC/RPMS
4. 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. This number will vary
from release to release.
5. Install the RPM:
# rpm -Uvh hptc-upgrade-1-n.noarch.rpm
6. Go back to the home directory:
# cd
7. Run the following script to 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.
