.SH DESCRIPTION
.sp
.LP
The \fBitu\fR utility converts driver packages to Driver Update (DU) format and
patches a Solaris install media with driver packages for Install Time Update
(ITU). \fBitu\fR has three subcommands: \fBmakedu\fR, \fBupdatemedia\fR and
\fBmakeiso\fR.

.RE

.SH SUB-COMMANDS
.sp
.LP
The \fBitu\fR subcommands are described as follows.
.SS "\fBmakedu\fR"
.sp
.LP
The \fBmakedu\fR 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.
.sp
.LP
The \fB-r\fR option is required to specify the Solaris release number for which
the driver updates apply. The \fIsolaris_release\fR option argument takes the
form \fBuname\fR \fB-r\fR output, for example, \fB5.10\fR or \fB5.11\fR.
.sp
.LP
If the \fB-d\fR option is specified, the resulting DU directory tree is placed
in the directory \fIoutput_dir\fR.
.sp
.LP
If the \fB-o\fR option is specified, a (non-bootable) ISO image of the DU
directory tree is written in the file \fIiso_file\fR. This ISO image can be
burned onto a CD/DVD using \fBcdrw\fR(1) or \fBcdrecord(1)\fR (not a SunOS man
page). See the "Examples" section below for an example of creating a DU on a
floppy.
.sp
.LP
At least one of \fB-d\fR and \fB-o\fR option must be specified. If both are
specified, then both an ISO image and a directory tree are generated.
.SS "\fBupdatemedia\fR"
.sp
.LP
The \fBupdatemedia\fR subcommand takes a list of driver packages as input and
applies them to the miniroot of a Solaris install media. It also places them in
a subdirectory called \fBITUs\fR under the Solaris install media's top-level
directory:
.sp
.in +2
.nf
\fImedia_root\fR/ITUs
.fi
.in -2
.sp

.sp
.LP
When booting a system from the updated media, the  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.
.sp
.LP
The \fB-R\fR 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 \fBitu\fR.
.sp
.LP
If the \fB-o\fR option is specified, a bootable ISO image of the patched
install media is also created in the file \fIiso_file\fR. The ISO image can
then be burned onto a CD or DVD.
.SS "\fBmakeiso\fR"
.sp
.LP
The \fBmakeiso\fR subcommand runs \fBmkisofs(8)\fR to create a bootable Solaris
ISO image of the Solaris install media \fImedia_root\fR and writes it to the
file \fIiso_file\fR. The ISO image file can then be burned onto a CD or DVD
with utilities such as \fBcdrw\fR(1) or \fBcdrecord(1)\fR. (Note that
\fBmkisofs(8)\fR and \fBcdrecord(1)\fR are not SunOS man pages.)
.LP
Caution -
.sp
.RS 2
The Solaris install media \fImedia-root\fR must contain the file
\fBboot/grub/stage2_eltorito\fR, 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.
.RE

.sp

.SH EXAMPLES
.LP
\fBExample 1 \fRCreating a DU CD/DVD
.sp
.LP
The following commands create a Driver Update CD/DVD containing the packages
\fBSAMPLEpkg1\fR and \fBSAMPLEpkg2\fR.

.sp
.in +2
.nf
# \fBitu makedu -r 5.10 -o my.iso SAMPLEpkg1 SAMPLEpkg2\fR
# \fBcdrw -i my.iso\fR
.fi
.in -2
.sp

.LP
\fBExample 2 \fRCreating a DU Floppy
.sp
.LP
The following commands create a Driver Update floppy containing the driver
package \fBMYdriver\fR.

.sp
.in +2
.nf
# \fBrmformat -F quick /dev/rdiskette\fR
# \fBmkfs -F pcfs /dev/rdiskette\fR
# \fBmount -F pcfs /dev/diskette /mnt\fR
# \fB/usr/bin/itu makedu -r 5.10 -d /mnt /export/MYdriver\fR
# \fBumount /mnt\fR
# \fBdd if=/dev/rdiskette of=floppy.dd\fR
.fi
.in -2
.sp

.sp
.LP
The \fBitu\fR command above creates the DU directly onto the floppy mounted on
\fB/mnt\fR. The \fBdd\fR invocation stores an image of the floppy in the file
\fBfloppy.dd\fR. This is useful for distributing a DU floppy in file form. From
the file, the floppy can then be recreated as follows:

.sp
.in +2
.nf
# \fBdd if=floppy.dd of=/dev/rdiskette\fR
.fi
.in -2
.sp

.LP
\fBExample 3 \fRCreating a Bootable ISO Image
.sp
.LP
The following commands create the bootable ISO image \fBmydvd.iso\fR of the
Solaris install image \fB/export/solaris-10u1\fR with ISO label
"\fBSpecial-S10\fR".

.sp
.in +2
.nf
# \fB/usr/bin/itu makeiso -o mydvd.iso -l "Special-S10" \e
     /export/solaris-10u1\fR
# \fBcdrw -i mydvd.iso\fR
