Abstract
The following document example how to create your own bootable dvd using Ignite-UX 7.2.x and later.
Create the DVD
# lvcreate -L 8000 -n image /dev/vg00 # newfs -F vxfs -o largefiles -b 8192 /dev/vg00/rimage # mkdir /var/tmp/image # mount -F vxfs -o largefiles /dev/vg00/image /var/tmp/image # mkdir /var/tmp/image/archives # mkdir /var/tmp/image/iso
Create the required golden image
# /opt/ignite/data/scripts/make_sys_image \
-s local -d /var/tmp/image/archives \
-n B.11.11_archive.gz
* Preparing to create a system archive.
* Testing for necessary pax patch.
WARNING: CLEAN_LEVEL set to 2: (see -l option for make_sys_image(1M))
While this command is executing at clean level 2, the system
should be as quiet as possible. The host and/or networking
information on the system are temporarily set to newconfig
values. After the command is complete these files are
returned to their previous state.

Check archive size
# ll /var/tmp/image/archives/B.11.11_archive.gz -rw-r--r-- 1 root sys 1736255712 Feb 2 16:41 /var/tmp/image/archives/B.11.11_archive.gz
Create the bootable DVD ISO image
# /opt/ignite/data/scripts/examples/make_media_install \ -r B.11.11 -o 64w -p /var/tmp/image \ -a B.11.11_archive.gz -m /var/tmp/image/iso
Step 1: Make Ignite-UX config files for golden image archive(s)
+ /opt/ignite/lbin/make_arch_config -L /var/tmp/image/archives/. -n B.11.11_archive.gz -d B.11.11_archive.gz (B.11.11) -c /var/tmp/image/iso/cfgs/B.11.11_archive.gz.cfg.tmp -m t -C g -r pa -b 64 -i 1 -t 999 + (modify /var/tmp/image/iso/cfgs/B.11.11_archive.gz.cfg.tmp => /var/tmp/image/iso/cfgs/B.11.11_archive.gz.cfg)
Step 2: Copy SD depot(s) and make config files for them
Step 3: Make a boot-image (LIF volume)
+ /opt/ignite/bin/make_medialif -o 64w -r B.11.11 -f /opt/ignite/data/Rel_B.11.11/config -f /var/tmp/image/iso/cfgs/B.11.11_archive.gz.cfg -l /var/tmp/image/bootvol.lif + /opt/ignite/bin/instl_adm -b -F /var/tmp/image/bootvol.lif
Step 4: Make ISO media image
+ /opt/ignite/lbin/mkisofs -U -max-iso9660-filenames -R -eltorito-alt-boot -no-emul-boot -b bootvol.lif /var/tmp/image/iso/image.iso /var/tmp/image Warning: creating filesystem that does not conform to ISO-9660. Warning: ISO-9660 filenames longer than 31 may cause buffer overflows in the OS. Size of boot image is 135856 sectors -> No emulation 0.57% done, estimate finish Sat Feb 2 17:20:50 2008 1.13% done, estimate finish Sat Feb 2 17:20:50 2008 1.70% done, estimate finish Sat Feb 2 17:20:50 2008 ... 99.21% done, estimate finish Sat Feb 2 17:22:56 2008 99.78% done, estimate finish Sat Feb 2 17:22:56 2008 Total translation table size: 2048 Total rockridge attributes bytes: 1581 Total directory bytes: 10240 Path table size(bytes): 82 Max brk space used 13000 881930 extents written (1722 MB)
Step 5: Combine LIF volume and media image
+ /opt/ignite/lbin/instl_combine -C /var/tmp/image/iso/image.iso El Torito offset for LIF volume is: 0x10000 Adjusting LIF file: ISL (Old iplstart: 4096; New iplstart: 69632) Adjusting LIF file: AUTO Adjusting LIF file: INDEX Adjusting LIF file: CONFIG Adjusting LIF file: HPUX Adjusting LIF file: WINSTALL Adjusting LIF file: WINSTALLFS Adjusting LIF file: FWWKAR Adjusting LIF file: INSTCMDS Adjusting LIF file: SYSCMDS Adjusting LIF file: SCRIPTS Adjusting LIF file: PAD
Step 6: Write image file to tape/CD/DVD media
+ /opt/ignite/lbin/growisofs -Z /dev/rdsk/c0t0d0=/var/tmp/image/iso/image.iso
:-( 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/c0t0l0'
+ Error 83 /opt/ignite/lbin/growisofs failed.
/opt/ignite/data/scripts/examples/make_media_install: ERROR: /opt/ignite/lbin/growisofs failed.
The /var/tmp/image/iso/image.iso needs to be move to a system with DVD writable hardware.
- The final error message is normal, because the system will not burn the image directly. If you DVD burner is supported, you may run the recommended commands mknod /dev/rscsi/c#t#l# c 203 0x000002; chmod 0600 /dev/rscsi/c#t#l# using your DVD writer device special file. That will allow the image to be write directly on your server.
- Remember to remove the ISO image any time that your will reuse the process!!!
- On Integrity bases systems, the command to create the ISO image needs some modifications to create IA64 bootable media. For example, for HP-UX 11i v2 (11.23) media, you should use:
# /opt/ignite/data/scripts/examples/make_media_install \ -r B.11.23 -o IA -p /var/tmp/image \ -a B.11.23_archive.gz -m /var/tmp/image/iso

Unable to create 2 GB+ iso images on HP-UX 11.31
The Ignite-UX above C.6.5 offers support for archives larger that 2GB (up to around 4 GB). On Ignite-UX C.7.4.157 and below under HP-UX 11.31 there is a problem using archives larger that 2 Gigabytes. The problem is that the make_media_install script checks the existence of kernel patch PHKL_33110 and above of the CDFS filesystem. On HP-UX 11.31 this patch is not required neither exists, so the system failed to test the script. If upgrating to the latest version of Ignite-UX is not possible, as a workaround you may add the following lines to the make_media_install script to bypass the testing.
# diff make_media_install.orig make_media_install 1388a1389,1393 > # Disable testing on HP-UX 11.31 > OSRELEASE=`uname -r` > if [ $OSRELEASE = "B.11.31" ]; then > break > fi
Example:
function CheckLargeFile
{
typeset archive_at size
# To avoid shell math problems on a 32-bit system, get the file size in
# 1024-byte blocks, and look for >= 2^21 = 2097152 blocks:
((archive_at = 0)); while (((archive_at += 1) <= Archives))
do
size="$(du -sk ${Archive[$archive_at]} 2>/dev/null |
awk '{print $1}')"
[[ -z "$size" ]] && continue
((size < 2097152)) && continue
# Have a large file, so check each install kernel in $LIF_vol:
#
# Note: Use for-loop, not pipe to while-loop, to avoid trying to Error() from
# a subshell.
typeset file patch
for file in $(lifls -l "$LIF_vol" |
awk '($1 ~ /INSTALL$/) {print $1}')
do
# Disable testing on HP-UX 11.31
OSRELEASE=`uname -r`
if [ $OSRELEASE = "B.11.31" ]; then
break
fi
patch="$(lifcp "$LIF_vol:$file" - |
# gzcat | # turn on if install kernels are compressed.
sed -n '/cdfs_vnops.*PHKL_/s/.*PHKL_//p' |
cut -c1-5)"
if [[ -z "$patch" ]] || ((patch < 33110))
then

'is 2 Gb (2^31) bytes or larger, and it appears' \
"at least one install kernel (\"$file\") copied" \
