Task 8: Configure the System and Propagate the Golden Image

Back up the existing configuration and management database and migrate existing data to the new release format:

# upgradesys-lxc

Command output is similar to the following:

The upgradesys-lxc utility performs all the necessary steps
to upgrade your cluster.  This script should be run immediately 
after you have upgraded the head node with the latest XC software 
and any third party vendor rpms.

	IMPORTANT: Do not proceed to the next step in the upgrade process if the output from the upgradesys-lxc script indicates failures. If you cannot determine how to resolve these errors, contact the HP XC Support team at the following e-mail address: <xc_support@hp.com>

Review the /opt/hptc/systemimager/etc/base_exclude_file to determine if you want to exclude files from the golden image beyond what is already excluded. The base_exclude file file is the file that is read when the golden image is re-created as part of the upgrade process. The HP XC System Software Administration Guide describes how to add exclusions to this file.

Use the information in Table 5-6 to decide on the cluster_config option to use to configure the upgraded system.

Change directory to the configuration directory:

# cd /opt/hptc/config/sbin

Specify one of the following cluster_config options:

View the role assignments when the cluster_config utility displays the command-line options menu:

[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: l

When are satisfied with the role assignments, enter the letter p to proceed with the system configuration process:

[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: p

Do you want to apply your changes to the cluster configuration? [y/n]  y
[S]ervices Config, [P]roceed, [Q]uit: p

Do you want to apply your changes to the service configuration? [y/n] y

The cluster_config utility prompts you to supply system configuration information. As services are being configured, provide the answers listed in Table 5-7.

Follow along on the screen while the cluster_config utility configures the system.

	NOTE: To avoid duplicating command output here, cluster_config output is shown in “Task 10: Respond to Configuration Questions”.

Continue to the next step in this procedure when the cluster_config processing is complete.

Look at the backup copy of the slurm.conf file, which is located in the /hptc_cluster/slurm/etc/slurm.conf.bak file. If you previously customized this file, you must merge those customizations into the new version of the /hptc_cluster/slurm/etc/slurm.conf file. Otherwise, omit this step.
