This section assumes the system creating the media has a DVD writer.

If your system does not have a DVD writer, you can create the ISO image and then copy it to another system equipped with a DVD writer to burn the media.

If your system is enabled with the HP Integrity Integrated Lights-Out Management Processor (iLO MP) virtual media (vMedia) feature, you can generate an ISO image that can be used with iLO vMedia virtual devices. For more information, see Appendix D and the HP Integrity iLO 2 MP Operations Guide available on www.docs.hp.com.

File and ISO Image Size Considerations

Prior to Ignite-UX version C.6.5.x for HP-UX 11i v2 and C.6.8.x for HP-UX 11i v1, the total size of the ISO image cannot be larger than 2 GB.

The ISO image must fit on the DVD media (4.7 GB).

The ISO9660 specification limits the maximum file size to 2 GB.

For more information, see the sections FILE SIZES and IMAGE SIZE at the start of the make_media_install script.

Using the make_media_install and the make_opticaldisc_recovery scripts

The make_media_install script greatly simplifies the creation of custom bootable DVD media. With one simple command line, a CD/DVD can be created that supports two-step media recovery. Additionally, make_media_install can write archives to a bootable DVD.

All HP-UX 11i v2 and 11i v3 bootable CD/DVDs created with make_media_install support both Itanium-based and PA-RISC boot.

The make_opticaldisc_recovery script can be used to create a recovery image and then write it to a DVD. The script creates the recovery image with make_net_recovery, and then calls make_media_install to write the recovery image to DVD. This script is to be run from the client system, and requires one argument — the hostname or IP address of the Ignite server. The script first creates a recovery image of the client and stores it on the Ignite server. Then, the recovery image is written to the Ignite server's DVD writer. The make_opticaldisc_recovery script was introduced in Ignite-UX version C.7.2.

You can find both scripts in the directory


Detailed usage information is available via

#make_media_install -?

and summary information is available via

#make_opticaldisc_recovery -?

Additional information is available at the start of the scripts.

Error messages

No DVD available

The make_media_install script will automatically write the .iso image (default file name is image.iso) to the DVD. If there is no writable DVD available, the script will halt with a message similar to

:-[ LOAD TRAY failed with SK=5h/ASC=24h/ACQ=00h]: I/O error

The .iso file will remain in the iso_directory specified with the -m option. Make sure you have enough disk space in the iso_directory to hold the .iso image.

No DVD special files

Prior to the first time you run make_media_install, you must create DVD special files. If the DVD special files are missing when you run make_media_install, you will receive an error message similar to

:-( unable to open(“/dev/rscsi/c0t0l0”.O_RDONLY): No such file or directory :-! consider 'mknod /dev/rscsi/c0t0l0 c 203 0x000002; chmod 0600 /dev/rscsi/cotol0' + Error 83 /opt/ignite/lbin/growisofs failed. /opt/ignite/data/scripts/examples/make_media_install: ERROR: /opt/ignite/lbin/growisofs failed.

To add DVD special files:

  • Run the command mkdir /dev/rscsi

  • Then run the suggested mknod and chmod commands.

NOTE: If the system with the DVD writer is running HP-UX 11i v3, you must use a legacy device special file to identify the DVD.
Missing -c argument on HP-UX 11i v2 USB DVD drive

On an HP-UX 11i v2 system with a USB DVD drive, you must use the -c argument to make_media_install and install the patch PHKL_37814. For more information, see “Create HP-UX 11i v2 bootable DVD media on USB drive for two-step media recovery”. If the -c option was not used, an error message similar to the following will be displayed:

:-( unable to open ("/dev/rdsk/c0t0d0",O_RDONLY: No such device

Boot CD/DVD Creation Examples

Two-step media recovery using a bootable CD/DVD is necessary to restore from tapes created with the Ignite-UX command make_tape_recovery on certain Itanium-based systems that do not support direct tape boot. See “Tape Recovery With No Tape Boot Support — Two-Step Media Recovery” for more information on two-step media recovery and the Ignite-UX Installation Booting white paper at http://docs.hp.com/en/IUX/infolib.html for information on configurations supporting HP Integrity native tape boot.

Two-step media recovery requires the version of Ignite-UX on the tape, on the bootable CD/DVD, and on the system creating the CD/DVD media to be identical. If you do not have a matching Operating Environment DVD, the make_media_install script can be used to easily create a bootable CD/DVD with the correct Ignite-UX version.

Create HP-UX 11i v3 bootable CD/DVD media for two-step media recovery

On a system with a CD/DVD writer and the same version of Ignite-UX as on your tape, execute the following command (iso_directory is the target directory for the .iso media file and the -r option specifies the release, such as B.11.23 or B.11.31):

#make_media_install -r B.11.31 -m iso_directory

Create HP-UX 11i v2 bootable DVD media on USB drive for two-step media recovery

In order to write to a USB DVD drive on an HP-UX 11i v2 system, you must install the patch PHKL_37814 and use the -c option with make_media_install. In the following example, the iso_directory is the target directory for the .iso media file, the -r option specifies the release, and the device_file is the DVD device file such as /dev/rdsk/c0t0d0.

#make_media_install -r B.11.23 -m iso_directory -c device_file

Installation DVD Creation Examples

Installation media can be built for PA-RISC systems, Itanium-based systems, or both since the bootable DVD created with make_media_install on HP-UX 11i v2 or 11i v3 will support boot for either architecture. The archive, however, can only be installed on a system matching the architecture type it was created from.

The make_media_install script will generate impact statements for you, using either the -l command line option or the default $ImpactLevelDefault. See the start of the script for more information.

NOTE: Building installation DVDs requires the mkisofs and growisofs commands. Beginning with Ignite-UX version C.6.2.x, these commands are delivered in the /opt/ignite/lbin/ directory.

Put an Itanium-based HP-UX 11i v3 golden archive on a DVD

The following examples will write golden archives created with the make_sys_image command to DVD.

On a system with a DVD writer, execute the following commands. (The iso_directory is the target directory for the .iso media file. The -r option specifies the release — valid values for Itanium-based systems are B.11.23 and B.11.31. The -o option specifies the hardware architecture — the only valid value for an Itanium-based system is IA.)

#mkdir /var/opt/ignite/media/pseudo_root/archive #cp goldenarchive.gz /var/opt/ignite/media/pseudo_root/archive #make_media_install -r B.11.31 -o IA -a goldenarchive.gz -m iso_directory

Put a PA-RISC HP-UX 11i v2 golden archive on a DVD

On a system with a DVD writer, execute the following commands. (The iso_directory is the target directory for the .iso media file. The -r option specifies the release, such as B.11.11, B.11.23, or B.11.31. The -o option specifies the hardware architecture — valid choices on a PA-RISC system are: 32, 64v, or 64w.)

#mkdir /var/opt/ignite/media/pseudo_root/archive #cp goldenarchive.gz /var/opt/ignite/media/pseudo_root/archive #make_media_install -r B.11.23 -o 64w -a goldenarchive.gz -m iso_directory

Put two HP-UX 11i v2 golden archives, one Itanium-based and one PA-RISC, on a DVD

The Itanium-based golden archive can only be installed on another Itanium-based system. Similarly, the PA-RISC golden archive can only be installed on another PA-RISC system. The DVD will be able to boot either type of architecture.

On a system with a DVD writer, execute the following commands. (The file suffixes .pa.gz and .ia.gz replace the make_media_install -o option. The iso_directory is the target directory for the .iso media file. The -r option specifies the release, such as B.11.23, or B.11.31.)

#mkdir /var/opt/ignite/media/pseudo_root/archive #cp PAgoldenarchive.pa.gz /var/opt/ignite/media/pseudo_root/archive #cp IAgoldenarchive.ia.gz /var/opt/ignite/media/pseudo_root/archive #make_media_install -r B.11.23 -a PAgoldenarchive.pa.gz \ -a IAgoldenarchive.ia.gz -m iso_directory

Create a recovery DVD

Create a recovery image of the current system on the named Ignite-UX server, and write that recovery image to the DVD writer on the server system by issuing the following command on the client system.

#make_opticaldisc_recovery Ignite_server_name

Create an HP-UX 11i v2 Itanium-based recovery DVD using an existing network recovery image

Run the following command from the Ignite-UX server on which the recovery image exists. (The -r option specifies the HP-UX release, and the -o option specifies the hardware architecture.)

#/opt/ignite/data/scripts/examples/make_media_install \ -r B.11.23 -o IA \ -f /var/opt/ignite/clients/client/recovery/archive/archive_cfg \ -f /var/opt/ignite/clients/client/recovery/archive/control_cfg \ -f /var/opt/ignite/clients/client/recovery/archive/system_cfg \ -a archive.gz \ -m /var/opt/ignite/recovery/archives/client
