b. Stop the processes that are using /hptc_cluster. Typically, the processes using
/hptc_cluster correlate to the cmfd, nagios, lsf, slurm, and syslog-ng services.
Use the following syntax to stop those services:
# service service_name stop
c. Run the fuser command again to make sure no processes are using /hptc_cluster:
# fuser -vm /hptc_cluster
d. Proceed to step 7 when you have verified that no processes are using /hptc_cluster.
7. If SFS is in use, stop the SFS service:
# service sfs stop
# chkconfig sfs off
Proceed to Section 9.4 (page 142).
9.4 Installing the Upgrade RPM and Preparing the System
Follow this procedure to install the upgrade RPM, and run the preupgradesys script, which
performs the necessary preprocessing to prepare the head node:
1. Insert the HP XC System Software Version 4.0 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-3-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-3-n.noarch.rpm
7. Remove the SFS RPM files.
8. This step is required only if the head node is an HP Integrity system. Otherwise, skip this
step.
The /etc/fstab file on the head node must include two zeroes in the last two columns
for the /hptc_cluster entry. The entry should be similar to the following:
/dev/sda5 /hptc_cluster csys hostaddress=172.20.0.8,_netdev 0 0
If two zeroes (0) are not present in the last two columns, use a text editor to add them.
9. Return to the home directory:
# cd
10. Save the current system configuration to a file to create a snapshot of the system configuration
before the upgrade:
# shownode config --admin > /var/log/shownode_config.txt
11. Prepare the system for the upgrade:
