How to setup your own file system layout for a Golden Images

Contents


Abstract

This document describes the required process to create a personalized file system layout for a golden image. The process can be followed when creating a network recovery archive or a recovery DVD.

General Process

1. Run a make_tape_recovery or use any previous one. The idea is to have a disk layout already created from the "Basic System", instead of create it manually from scratch (instl_adm(4)).

# make_tape_recovery –s <server> -p –v

2. Create Golden Image archive:

# make_sys_image -s <server> -d <destination_directory>

3. Create Golden Image configuration file. There are some example files located at /opt/ignite/data/examples that you will need to copy to a different location and modify. The modification of this file is out of the scope of this document.

# cp /opt/ignite/data/examples/B.11.31.golden_image.cfg /var/opt/ignite/data/Rel_B.11.31

4. Copy the system_cfg file for the client to a different location (The recommendation is to use the standard location):

# cp /var/opt/ignite/clients/delta/recovery/latest/system_cfg  /var/opt/ignite/data/Rel_B.11.31/disklayout

5. Remove all sections except the "Disk and Filesystems" section. Edit the file systems size as desired.

# cat disklayout

 #
 # Disk and Filesystems
 #
 _hp_disk_layout+={"HP-UX save_config layout"}
 (_hp_disk_layout=="HP-UX save_config layout") {

                } # end logical_volume
        } # end volume_group "vg00"
 } # end "HP-UX save_config layout"
}

6. When Ignite-UX is reading the configuration file, it needs to know if this configuration will be use for a PA-RISC or IA64 client. For this reason you will need to encapsulate the file system layout into a processor model section.

For PA-RISC clients use:

(is_hppa)

For IA64 clients use:

(is_ia64)

The resulting disklayout file should be similar to the following:

# cat disklayout

(is_hppa) {
 #
 # Disk and Filesystems
 #
 _hp_disk_layout+={"HP-UX save_config layout"}
 (_hp_disk_layout=="HP-UX save_config layout") {

 ...

        } # end volume_group "vg00"
 } # end "HP-UX save_config layout"
}

7. Modify /var/opt/ignite/INDEX file. Add a new section for the new archive:

# cat /var/opt/ignite/INDEX

# /var/opt/ignite/INDEX
# This file is used to define the Ignite-UX configurations
# and to define which config files are associated with each
# configuration.  See the ignite(5), instl_adm(4), and
# manage_index(1M) man pages for details.
#
# NOTE: The manage_index command is used to maintain this file.
#       Comments, logic expressions and formatting changes are not
#       preserved by manage_index.
#
# WARNING: User comments (lines beginning with '#' ), and any user
#          formatting in the body of this file are _not_ preserved
#          when the version of Ignite-UX is updated.
#
cfg "HP-UX B.11.11 Default" {
        description "This selection supplies the default system configuration that HP supplies for the B.11.11 release."
        "/opt/ignite/data/Rel_B.11.11/config"
        "/opt/ignite/data/Rel_B.11.11/hw_patches_cfg"
        "/var/opt/ignite/config.local"
}
cfg "HP-UX B.11.23 Default" {
        description "This selection supplies the default system configuration that HP supplies for the B.11.23 release."
        "/opt/ignite/data/Rel_B.11.23/config"
        "/opt/ignite/data/Rel_B.11.23/hw_patches_cfg"
        "/var/opt/ignite/config.local"
}
cfg "HP-UX B.11.31 Default" {
        description "This selection supplies the default system configuration that HP supplies for the B.11.31 release."
        "/opt/ignite/data/Rel_B.11.31/config"
        "/opt/ignite/data/Rel_B.11.31/hw_patches_cfg"
        "/var/opt/ignite/config.local"
}
cfg "HP-UX B.11.31 MyNewGoldenImage" {
        description "This selection supplies the default system configuration that HP supplies for the B.11.31 release."
        "/opt/ignite/data/Rel_B.11.31/config"
        "/var/opt/ignite/data/Rel_B.11.31/B.11.31.golden_image.cfg"
        "/var/opt/ignite/data/Rel_B.11.31/disklayout"
        "/opt/ignite/data/Rel_B.11.31/hw_patches_cfg"
        "/var/opt/ignite/config.local"
}

8. During the installation process, just select “HP-UX B.11.31 MyNewGoldenImage” to load the file system layout you specified. You will see the “HP-UX save_config layout” entry in the Basic Tab view. Also, you can check the File System Tab to review your file system size definitions.
