Many things are new in Solaris 11, Autoinstall is one of them. If, like me, you've known Jumpstart for the last 2 centuries or so, you'll have to start from scratch. Well, almost, as the concepts are similar, and it's not all that difficult. Just new.
I wanted to have an AI server that I could use for demo purposes, on the train if need be. That answers the question of hardware requirements: portable. But let's start at the beginning.
First, you need an OS image, of course. In the new world of Solaris 11, it is now called a repository. The original can be downloaded from the Solaris 11 page at Oracle. What you want is the "Oracle Solaris 11 11/11 Repository Image", which comes in two parts that can be combined using cat. MD5 checksums for these (and all other downloads from that page) are available closer to the top of the page.
With that, building the repository is quick and simple:
# zfs create -o mountpoint=/export/repo rpool/ai/repo
# zfs create rpool/ai/repo/s11
# mount -o ro -F hsfs /tmp/sol-11-1111-repo-full.iso /mnt
# rsync -aP /mnt/repo /export/repo/s11
# umount /mnt
# pkgrepo rebuild -s /export/repo/sol11/repo
# zfs snapshot rpool/ai/repo/sol11@fcs
# pkgrepo info -s /export/repo/sol11/repo
PUBLISHER PACKAGES STATUS UPDATED
solaris 4292 online 2012-03-12T20:47:15.378639Z
That's all there's to it. Let's make a snapshot, just to be on the safe side. You never know when one will come in handy. To use this repository, you could just add it as a file-based publisher:
# pkg set-publisher -g file:///export/repo/sol11/repo solaris
In case I'd want to access this repository through a (virtual) network, i'll now quickly activate the repository-service:
# svccfg -s application/pkg/server \
setprop pkg/inst_root=/export/repo/sol11/repo
# svccfg -s application/pkg/server setprop pkg/readonly=true
# svcadm refresh application/pkg/server
# svcadm enable application/pkg/server
That's all you need - now point your browser to http://localhost/ to view your beautiful repository-server. Step 1 is done. All of this, by the way, is nicely documented in the README file that's contained in the repository image.
Of course, we already have updates to the original release. You can find them in MOS in the Oracle Solaris 11 Support Repository Updates (SRU) Index. You can simply add these to your existing repository or create separate repositories for each SRU. The individual SRUs are self-sufficient and incremental - SRU4 includes all updates from SRU2 and SRU3. With ZFS, you can also get both: A full repository with all updates and at the same time incremental ones up to each of the updates:
# mount -o ro -F hsfs /tmp/sol-11-1111-sru4-05-incr-repo.iso /mnt
# pkgrecv -s /mnt/repo -d /export/repo/sol11/repo '*'
# umount /mnt
# pkgrepo rebuild -s /export/repo/sol11/repo
# zfs snapshot rpool/ai/repo/sol11@sru4
# zfs set snapdir=visible rpool/ai/repo/sol11
# svcadm restart svc:/application/pkg/server:default
The normal repository is now updated to SRU4. Thanks to the ZFS snapshots, there is also a valid repository of Solaris 11 11/11 without the update located at /export/repo/sol11/.zfs/snapshot/fcs . If you like, you can also create another repository service for each update, running on a separate port.
But now lets continue with the AI server. Just a little bit of reading in the dokumentation makes it clear that we will need to run a DHCP server for this. Since I already have one active (for my SunRay installation) and since it's a good idea to have these kinds of services separate anyway, I decided to create this in a Zone. So, let's create one first:
# zfs create -o mountpoint=/export/install rpool/ai/install
# zfs create -o mountpoint=/zones rpool/zones
# zonecfg -z ai-server
zonecfg:ai-server> create
create: Using system default template 'SYSdefault'
zonecfg:ai-server> set zonepath=/zones/ai-server
zonecfg:ai-server> add dataset
zonecfg:ai-server:dataset> set name=rpool/ai/install
zonecfg:ai-server:dataset> set alias=install
zonecfg:ai-server:dataset> end
zonecfg:ai-server> commit
zonecfg:ai-server> exit
# zoneadm -z ai-server install
# zoneadm -z ai-server boot ; zlogin -C ai-server
Give it a hostname and IP address at first boot, and there's the Zone. For a publisher for Solaris packages, it will be bound to the "System Publisher" from the Global Zone. The /export/install filesystem, of course, is intended to be used by the AI server. Let's configure it now:
#zlogin ai-server
root@ai-server:~# pkg install install/installadm
root@ai-server:~# installadm create-service -n x86-fcs -a i386 \
-s pkg://solaris/install-image/
[email protected],5.11-0.175.0.0.0.2.1482 \
-d /export/install/fcs -i 192.168.2.20 -c 3
With that, the core AI server is already done. What happened here? First, I installed the AI server software. IPS makes that nice and easy. If necessary, it'll also pull in the required DHCP-Server and anything else that might be missing. Watch out for that DHCP server software. In Solaris 11, there are two different versions. There's the one you might know from Solaris 10 and earlier, and then there's a new one from ISC. The latter is the one we need for AI. The SMF service names of both are very similar. The "old" one is "svc:/network/dhcp-server:default". The ISC-server comes with several SMF-services. We at least need "svc:/network/dhcp/server:ipv4".
The command "installadm create-service" creates the installation-service. It's called "x86-fcs", serves the "i386" architecture and gets its boot image from the repository of the system publisher, using version 5.11,5.11-0.175.0.0.0.2.1482, which is Solaris 11 11/11. (The option "-a i386" in this example is optional, since the installserver itself runs on a x86 machine.) The boot-environment for clients is created in /export/install/fcs and the DHCP-server is configured for 3 IP-addresses starting at 192.168.2.20. This
configuration is stored in a very human readable form in /etc/inet/dhcpd4.conf. An AI-service for SPARC systems could be created in the very same way, using "-a sparc" as the architecture option.
Now we would be ready to register and install the first client. It would be installed with the default "solaris-large-server" using the publisher "http://pkg.oracle.com/solaris/release" and would query it's
configuration interactively at first boot. This makes it very clear that an AI-server is really only a boot-server. The true source of packets to install can be different. Since I don't like these defaults for my demo setup, I did some extra config work for my clients.
The
configuration of a client is controlled by manifests and profiles. The manifest controls which packets are installed and how the filesystems are layed out. In that, it's very much like the old "rules.ok" file in Jumpstart. Profiles contain additional
configuration like root passwords, primary user account, IP addresses, keyboard layout etc. Hence, profiles are very similar to the old sysid.cfg file.
The easiest way to get your hands on a manifest is to ask the AI server we just created to give us it's default one. Then modify that to our liking and give it back to the installserver to use:
root@ai-server:~# mkdir -p /export/install/configs/manifests
root@ai-server:~# cd /export/install/configs/manifests
root@ai-server:~# installadm export -n x86-fcs -m orig_default \
-o orig_default.xml
root@ai-server:~# cp orig_default.xml s11-fcs.small.local.xml
root@ai-server:~# vi s11-fcs.small.local.xml
root@ai-server:~# more s11-fcs.small.local.xml

Manifest Status Criteria
-------- ------ --------
S11 Small fcs local Default None
orig_default Inactive None
The major points in this new manifest are:
Install "solaris-small-server"
Install a few locales less than the default. I'm not that fluid in French or Japanese...
Use my own package service as publisher, running on IP address 192.168.2.12
Install the initial release of Solaris 11: pkg:/
[email protected],5.11-0.175.0.0.0.2.0
Using a similar approach, I'll create a default profile interactively and use it as a template for a few customized building blocks, each defining a part of the overall system
configuration. The modular approach makes it easy to configure numerous clients later on:
root@ai-server:~# mkdir -p /export/install/configs/profiles
root@ai-server:~# cd /export/install/configs/profiles
root@ai-server:~# sysconfig create-profile -o default.xml
root@ai-server:~# cp default.xml general.xml; cp default.xml mars.xml
root@ai-server:~# cp default.xml user.xml
root@ai-server:~# vi general.xml mars.xml user.xml
root@ai-server:~# more general.xml mars.xml user.xml

Profile Criteria
------- --------
general.xml None
mars.xml ipv4 = 192.168.2.100
user.xml None
Here's the idea behind these files:
"general.xml" contains settings valid for all my clients. Stuff like DNS servers, for example, which in my case will always be the same.
"user.xml" only contains user definitions. That is, a root password and a primary user.Both of these profiles will be valid for all clients (for now).
"mars.xml" defines network settings for an individual client. This profile is associated with an IP-Address. For this to work, I'll have to tweak the DHCP-settings in the next step:
root@ai-server:~# installadm create-client -e 08:00:27:AA:3D:B1 -n x86-fcs
root@ai-server:~# vi /etc/inet/dhcpd4.conf
root@ai-server:~# tail -5 /etc/inet/dhcpd4.conf
host 080027AA3DB1 {
hardware ethernet 08:00:27:AA:3D:B1;
fixed-address 192.168.2.100;
filename "01080027AA3DB1";
}
This completes the client preparations. I manually added the IP-Address for mars to /etc/inet/dhcpd4.conf. This is needed for the "mars.xml" profile. Disabling arbitrary DHCP-replies will shut up this DHCP server, making my life in a shared environment a lot more peaceful ;-)Now, I of course want this installation to be completely hands-off. For this to work, I'll need to modify the grub boot menu for this client slightly. You can find it in /etc/netboot. "installadm create-client" will create a new boot menu for every client, identified by the client's MAC address. The template for this can be found in a subdirectory with the name of the install service, /etc/netboot/x86-fcs in our case. If you don't want to change this manually for every client, modify that template to your liking instead.

Now just boot the client off the network using PXE-boot. For my demo purposes, that's a client from VirtualBox, of course. That's all there's to it. And despite the fact that this blog entry is a little longer - that wasn't that hard now, was it?
