.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 and patches for Install Time Update (ITU). \fBitu\fR has three subcommands: \fBmakedu\fR, \fBupdatemedia\fR and \fBmakeiso\fR.

.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). 
.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 and patches 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 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.
.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.

.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 \fRPatching the Solaris Install Media
.sp
.LP
The following command patches the Solaris install media in \fB/export/s10u1\fR with patch \fB/opt/patches/123456-07\fR and driver package \fB/opt/pkgs/MYdriver\fR. The command also creates a bootable ISO image with ISO label "\fBMyS10U1\fR" in the file \fB/tmp/dvd.iso\fR.

.sp
.in +2
.nf
# \fB/usr/bin/itu updatemedia -R /export/s10u1 -o /tmp/dvd.iso -l MyS10U1 \e
       /opt/patches/123456-07 /opt/pkgs/MYdriver\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
