HP XC System Software Installation Guide Version 3.2.1

9. Read the HP Scalable Visualization Array, V2.1.1 Release Notes before beginning the upgrade
procedure. Upgrade and reinstall procedures for SVA are part of Section 5.7 (page 128)
Proceed to “Task 2: Prepare the System State”.
5.3 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. If the system is configured with improved availability of services, stop the availability tool:
# transfer_from_avail
4. If you are using Serviceguard as the availability tool, identify and remove the Serviceguard
RPMs:
a. Identify the RPM names of the following Serviceguard RPMs that are installed on the
system:
# rpm -qa | grep pidentd
# rpm -qa | grep qs
# rpm -qa | grp serviceguard
b. Remove the RPM names obtained in the previous step:
# rpm -e pidentd-{version}
# rpm -e qs-A.{version}.rhel{version}
# rpm -e serviceguard-{version}.rhel{version}
5. Shut down all nodes except the head node:
# stopsys
6. If the /hptc_cluster file system is mounted over an HP StorageWorks Scalable File Share
server, perform the following ; otherwise, proceed to step 7.
a. Determine the processes that are using /hptc_cluster:
# fuser -vm /hptc_cluster
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 HP SFS is in use, stop the SFS service:
# service sfs stop
Proceed to “Task 3: Install the Upgrade RPM and Prepare the System.”
5.4 Task 3: Install the Upgrade RPM and Prepare the System
Follow this procedure to install the upgrade RPM, and run the preupgradesys script, which
performs the necessary preprocessing to prepare the system:
1. Insert the HP XC System Software Version 3.2.1 DVD into the DVD drive on the head node.
2. Create the following directory:
