HP XC System Software Installation Guide Version 4.0

E.3.1 Enable Static Disk Configuration
Dynamic disk configuration method is the default behavior for the HP XC imaging environment.
Before you can use the static disk configuration method to customize the client disk configuration
you must enable it. You cannot use a combination of the two methods simultaneously.
Follow this procedure to enable static disk configuration:
1. Use the text editor of your choice to open the following file:
/etc/systemimager/systemimager.conf
2. Search for the following variable at the bottom of the file:
DYNAMIC_DISK_PROCESSING
3. Set the value to FALSE:
DYNAMIC_DISK_PROCESSING = FALSE
4. Save the changes to the file and exit the text editor.
The static disk configuration method is now persistently enabled. Each time the cluster_config
utility is run, one (or more) master autoinstallation scripts are created with static disk configuration
information from the appropriate .conf files.
E.3.2 Customize Client Disk Configuration
Customizing a client's disk configuration involves either editing an existing .conf file or creating
a new one. The format of the .conf file is explained in detail in autoinstallscript.conf(5) .
If you must create a new .conf file, HP recommends that you copy an existing *.conf file with
the proper disk architecture (/dev/sd, /dev/hd, /dev/cciss) as a starting point, and make
the necessary modifications to the copied file.
E.3.2.1 Example 1: Changing an Existing .conf File
As described in the previous section, predefined .conf files exist for each supported server
model. If a particular server model is part of an HP XC system, the associated .conf file is used
as input to a server-specific master autoinstallation script that is created during initialization of
the image replication environment, which is initiated as part of the cluster_config utility
processing.
The following procedure describes how to modify an existing server type .conf file:
1. Begin this procedure as the root user on the head node.
2. Save a copy of the existing .conf file before opening it for editing. The .conf files are
located in the /opt/hptc/systemimager/etc directory.
3. Use the text editor of your choice to make the disk configuration modifications to the .conf
file. See autoinstallscript.conf(5) for formatting guidelines.
4. Save the changes to the file and exit the text editor.
5. Run the cluster_config utility to create new master autoinstallation scripts
(/var/lib/systemimager/scripts/name.master.0) and generate an updated version
of the golden image:
# /opt/hptc/config/sbin/cluster_config
6. After the cluster_config utility completes its processing, the client nodes are ready to
be installed from the golden image. Do one of the following:
• If the client nodes were not previously installed with the HP XC System Software, see
“Running the startsys Utility to Start the System and Propagate the Golden Image”
(page 117) to continue the initial installation procedure.
• If the client nodes were previously installed, issue the following sequence of commands
to set the nodes to network boot and reboot the client nodes:
