HP XC System Software Installation Guide Version 3.2

4. If the system is configured with an InfiniBand interconnect, upgrade the HCA cards on all
nodes now.
Proceed to “Task 2: Prepare the System State”.
8.3 Task 2: Prepare the System State
On the head node, follow this procedure to ensure that the system is in the appropriate state for
the upgrade:
1. Set all nodes to network boot so that all client nodes can be reimaged after the head node is
updated:
# setnode --resync --all
2. Stop all running jobs. See the HP XC System Software User's Guide for specific instructions.
3. Shut down all nodes except the head node:
# stopsys
8.4 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-lxc 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/LYHPC/Redhat/RPMS
5. Find the full name of the hptc_lxc-upgrade RPM:
# ls hptc_lxc-upgrade*
hptc_lxc-upgrade-0.1-1.noarch.rpm
6. Install the RPM:
# rpm -Uvh hptc_lxc-upgrade-0.1-1.noarch.rpm
7. Return to the home directory:
# cd
8. Prepare the system for the upgrade:
# preupgradesys-lxc
The preupgradesys-lxc utility performs all the necessary
pre-processing steps needed to upgrade your cluster. This script
must be run before you upgrade your system.
