NAME
itu - convert packages to Driver Update format and patch Solaris install media for Install Time Update
SYNOPSIS
itu makedu -r solaris_release [-v] [-f] [-d output_dir] [-o iso_file]
[-l iso_label] package [package...]
itu patchmedia -R media_root [-v] [-f] [-o iso_file]
[-l iso_label] pkg_or_patch [pkg_or_patch...]
itu makeiso -o iso_file [-v] [-l iso_label] media_root
DESCRIPTION
The itu utility converts driver packages to Driver Update (DU) format and patches a Solaris install media with driver packages and patches
for Install Time Update (ITU). itu has three subcommands: makedu, patchmedia and makeiso.
OPTIONS
The following options are supported:
-d output_dir
Directory where the Driver Update directory is to be created.
-f
If output_dir/DU or iso_file already exists, remove it without asking first.
-l iso_label
Label/volume name of the ISO image (if -o option is specified).
-o iso_file
Path of the ISO image file to be created. For subcommands patchmedia and makeiso, it will be a bootable ISO image. This option must be
specified for subcommand makeiso.
-R media_root
Top-level directory of on-disk image of Solaris installation media. This option must be specified for subcommand patchmedia.
-r solaris_release
Solaris release number for which the Driver Update is intended. It takes the form of the output of uname -r, for example, 5.10. This
option must be specified for subcommand makedu.
-v
Verbose. Multiple -v options increase verbosity.
SUB-COMMANDS
The itu subcommands are described as follows.
makedu
The makedu subcommand takes one or more driver packages as input and converts them to DU format. At the beginning of an interactive Solaris
installation session, these driver updates can be applied to the running kernel, which will then also automatically apply them to the newly
installed Solaris at the end of the installation process.
The -r option is required to specify the Solaris release number for which the driver updates apply. The solaris_release option argument
takes the form uname -r output, for example, 5.10 or 5.11.
If the -d option is specified, the resulting DU directory tree is placed in the directory output_dir.
If the -o option is specified, a (non-bootable) ISO image of the DU directory tree is written in the file iso_file. This ISO image can be
burned onto a CD/DVD using cdrw(1) or cdrecord(1) (not a SunOS man page). See the "Examples" section below for an example of creating a DU
on a floppy.
At least one of -d and -o option must be specified. If both are specified, then both an ISO image and a directory tree are generated.
patchmedia
The patchmedia subcommand takes a list of driver packages and patches as input and applies them to the miniroot of a Solaris install media.
It also places them in a subdirectory called ITUs under the Solaris install media's top-level directory:
media_root/ITUs
When booting a system from the updated media, the patches and packages will be part of the booted Solaris image. They will also be applied
to the target system being installed at the end of the installation process.
The -R option must be entered on the command line to specify the Solaris install media. Note that the install media must be on a location
that is writable by itu.
If the -o option is specified, a bootable ISO image of the patched install media is also created in the file iso_file. The ISO image can
then be burned onto a CD or DVD.
makeiso
The makeiso subcommand runs mkisofs(8) to create a bootable Solaris ISO image of the Solaris install media media_root and writes it to the
file iso_file. The ISO image file can then be burned onto a CD or DVD with utilities such as cdrw(1) or cdrecord(1). (Note that mkisofs(8)
and cdrecord(1) are not SunOS man pages.)
Caution -
The Solaris install media media-root must contain the file boot/grub/stage2_eltorito, which will be written to the media boot sectors.
This file will be modified with some boot information, thus it has to be writable. If necessary, first save a copy, prior to running this
subcommand.
OPERANDS
The following operands are supported:
package [package...]
One or more driver packages.
pkg_or_patch [pkg_or_patch...]
One or more patches or packages.
media_root
The top-level directory of a Solaris install media.
EXAMPLES
Example 1 Creating a DU CD/DVD
The following commands create a Driver Update CD/DVD containing the packages SAMPLEpkg1 and SAMPLEpkg2.
# itu makedu -r 5.10 -o my.iso SAMPLEpkg1 SAMPLEpkg2
# cdrw -i my.iso
Example 2 Creating a DU Floppy
The following commands create a Driver Update floppy containing the driver package MYdriver.
# rmformat -F quick /dev/rdiskette
# mkfs -F pcfs /dev/rdiskette
# mount -F pcfs /dev/diskette /mnt
# /usr/bin/itu makedu -r 5.10 -d /mnt /export/MYdriver
# umount /mnt
# dd if=/dev/rdiskette of=floppy.dd
The itu command above creates the DU directly onto the floppy mounted on /mnt. The dd invocation stores an image of the floppy in the file
floppy.dd. This is useful for distributing a DU floppy in file form. From the file, the floppy can then be recreated as follows:
# dd if=floppy.dd of=/dev/rdiskette
Example 3 Patching the Solaris Install Media
The following command patches the Solaris install media in /export/s10u1 with patch /opt/patches/123456-07 and driver package
/opt/pkgs/MYdriver. The command also creates a bootable ISO image with ISO label "MyS10U1" in the file /tmp/dvd.iso.
# /usr/bin/itu patchmedia -R /export/s10u1 -o /tmp/dvd.iso -l MyS10U1
/opt/patches/123456-07 /opt/pkgs/MYdriver
Example 4 Creating a Bootable ISO Image
The following commands create the bootable ISO image mydvd.iso of the Solaris install image /export/solaris-10u1 with ISO label "Special-
S10".
# /usr/bin/itu makeiso -o mydvd.iso -l "Special-S10"
/export/solaris-10u1
# cdrw -i mydvd.iso
