I will post a script I used to create bunch of LDOMS on a T3-1 tomorrow.

The way I do it is I created a master system and created a snapshot. I then use zfs send / recv to duplicate the snapshot to another ldom. A few quick LDOM commands and you can have servers up in a few minutes.

First you need to create a snapshot of your master machine. I loaded the Solaris 10 8/11 ( buggy release but it's the lastest ) ISO into a folder on the local machine in /DVD/Solaris10/iso/

First create the zfs dataset that will hold your installation of LDOM1
zfs create logicalpool/ldoms
zfs create logicalpool/ldoms/ldom1
zfs set mountpoint=/ldom1 logipool/ldoms/ldom1

Create the image file that will hold our OS install:
mkfile -n 100g /ldom1/disk0.img ( 100gb may seem big but it leaves you plenty of room to live upgrade in the future for patches. We started out doing 25, then 50 and now the standard is 100gb. )

Note: I also suggest each machine have a physical lun attached. This way in the future you can make use of the ldm migrate feature.

Here is the script I use:

ldm add-domain ldom1
ldm set-vcpu 10 ldom1
ldm set-mau 0 ldom1
ldm set-mem 2g ldom1
ldm add-vnet vnet1 primary-vsw0 ldom1
ldm add-vdsdev /ldoms/ldom1/disk0.img vol200@primary-vds0
ldm add-vdisk vdisk200 vol200@primary-vds0 ohcinpuppettest01

Connect the Solaris 10 iso to the host:

ldm add-vdsdev /DVD/Solaris10/iso/sol10u10.iso s10u10iso@primary-vds0
ldm add-vdisk vdisk_iso s10u10iso@primary-vds0 ldom1

Misc final steps:
ldm set-variable autoboot\?=true ldom1
ldm bind ldom1
ldm start ldom1

At this point you should be able to run an ldm list command and see your local port that you can connect to.

Once you telnet to the ldom you will be at the {0} ok prompt. Type boot vdisk_iso and start the install process. You have a lot of options at this point. You can use a flar you have.. use a jumpstart server whatever you fancy. Note the T3/T4 are sun4v arch and a sun4u image will not work. I suggest creating a new image. Once you are complete you have patched and completed all your customizations you can then create a zfs snapshot and clone the machine. Run sys-unconfig and clear any naming IP from this master image before your snapshot.

zfs snapshot logipool/ldoms/ldom1@master

zfs send logipool/ldoms/ldom1@master | zfs recv logipool/ldoms/ldom2

Take the commands from above and create a new machine.

ldm add-domain ldom2
ldm set-vcpu 10 ldom2
ldm set-mau 0 ldom2
ldm set-mem 2g ldom2
ldm add-vnet vnet1 primary-vsw0 ldom1
ldm add-vdsdev /ldoms/ldom2/disk0.img vol201@primary-vds0
ldm add-vdisk vdisk201 vol201@primary-vds0 ldom2
ldm set-variable autoboot\?=true ldom2
ldm bind ldom2
ldm start ldom2

I script the whole thing and can be done with a new machine in less then 15 minutes.

Storage:

Create your pool of disks, depends on what type of devices you have.

zpool create ldomstor emcpower1c empower2c emcpower3c etc.
zfs create ldomstor/ldom1
zfs create -V 300g ldomstor/ldom1/ldom1-stor0
zfs create -V 300g ldomstor/ldom1/ldom1-stor1

ldm add-vdsdev /dev/zvol/dsk/ldomstor/ldom1/ldom1-stor0 ldom1stor0@primary-vds0
ldm add-vdsdev /dev/zvol/dsk/ldomstor/ldom1/ldom1-stor0 ldom1stor1@primary-vds0

ldm add-vdisk ldomstor0 ldom1stor0@primary-vds0 ldom1
ldm add-vdisk ldomstor1 ldom1stor1@primary-vds0 ldom1

Restart ldom1.

Once inside the domain you can see the new devices as disk using the format command. We create a second pool inside the domain for whatever the intended purpose may be.

apache2::build

Apache2::Build(3)					User Contributed Perl Documentation					 Apache2::Build(3)

NAME

       Apache2::Build - Methods for locating and parsing bits of Apache source code

SYNOPSIS

	use Apache2::Build ();
	my $build = Apache2::Build->new;

	# rebuild mod_perl with build opts from the previous build
	% cd modperl-2.0
	% perl -MApache2::Build -e rebuild

DESCRIPTION

       This module provides methods for locating and parsing bits of Apache source code.

       Since mod_perl remembers what build options were used to build it, you can use this knowledge to rebuild it using the same options. Simply
       chdir to the mod_perl source directory and run:

	 % cd modperl-2.0
	 % perl -MApache2::Build -e rebuild

       If you want to rebuild not yet installed, but already built mod_perl, run from its root directory:

	 % perl -Ilib -MApache2::Build -e rebuild

METHODS

       new Create an object blessed into the Apache2::Build class.

	    my $build = Apache2::Build->new;

       dir Top level directory where source files are located.

	    my $dir = $build->dir;
	    -d $dir or die "can't stat $dir $!
";

       find
	   Searches for apache source directories, return a list of those found.

	   Example:

	    for my $dir ($build->find) {
	       my $yn = prompt "Configure with $dir ?", "y";
	       ...
	    }

       inc Print include paths for MakeMaker's INC argument to "WriteMakefile".

	   Example:

	    use ExtUtils::MakeMaker;

	    use Apache2::Build ();

	    WriteMakefile(
		'NAME'	  => 'Apache2::Module',
		'VERSION' => '0.01',
		'INC'	  => Apache2::Build->new->inc,
	    );

       module_magic_number
	   Return the MODULE_MAGIC_NUMBER defined in the apache source.

	   Example:

	    my $mmn = $build->module_magic_number;

       httpd_version
	   Return the server version.

	   Example:

	    my $v = $build->httpd_version;

       otherldflags
	   Return other ld flags for MakeMaker's dynamic_lib argument to "WriteMakefile". This might be needed on systems like AIX that need
	   special flags to the linker to be able to reference mod_perl or httpd symbols.

	   Example:

	    use ExtUtils::MakeMaker;

	    use Apache2::Build ();

	    WriteMakefile(
		'NAME'	      => 'Apache2::Module',
		'VERSION'     => '0.01',
		'INC'	      => Apache2::Build->new->inc,
		'dynamic_lib' => {
		    'OTHERLDFLAGS' => Apache2::Build->new->otherldflags,
		},
	    );
