Solaris JumpStart

The Solaris 10 Operating System offers an automatic installation process, Solaris JumpStart software. The Solaris JumpStart procedure enables you to install the Solaris OS automatically and configure it differently, depending on the characteristics of client systems. These identifying characteristics are used to select the correct configuration for each client system.
The following tasks are required to configure a single JumpStart server to provide basic software installation services using the JumpStart procedures:
Spool the operating system image.
Edit the sysidcfg file.
Edit the profile and rules.
Run the check script.
Run the add_install_client script.
Boot the client.
Step #1
To spool the Solaris 10 boot and installation images to a local disk, complete the following steps: Create a directory with at least 800 Mbytes of space available to hold the Solaris OS image. Usually the /export/install directory is used.
mkdir /export/install
Insert the Solaris 10 Software 1 of 2 CD-ROM in the CD-ROM drive or the Solaris 10 DVD in the DVD drive. Change the directory to the location of the setup_install_server script.
cd /cdrom/cdrom0/s0/Solaris_10/Tools
Run the setup_install_server script to copy the Solaris 10 OS installation images to the local disk.
./setup_install_server /export/install
When the setup_install_server script finishes, change the directory to root (/), and eject the CD-ROM or DVD.
cd /
eject cdrom
If you use CD-ROM media, insert the Solaris 10 Software 2 of 2 CD-ROM in the CD-ROM drive. Change the directory to the location of the add_to_install_server script.
cd /cdrom/cdrom0/Solaris_10/Tools
Run the add_to_install_server script to copy the remainder of the installation image to the local disk.
./add_to_install_server /export/install
When add_to_install_server finishes, change the directory to root (/), and eject the CD-ROM.
cd /
eject cdrom
Step #2
The sysidcfg file keeps the various types of system information such as locale, time_zone, and so on, and supplies the information to the client at the booting time. Create a directory to hold the sysidcfg file. Typically the /export/config directory holds the sysidcfg file.
mkdir /export/config
Change the directory to /export/config, and create a file called sysidcfg using a text editor.
cd /export/config
vi sysidcfg
In the sysidcfg file, add the following lines. Substitute values that are appropriate for your systems, location, and network.
network_interface=primary {protocol-ipv6=no
netmask=255.255.255.0}

security_policy=none
name_service=none
time_zone=US/Mountain
system_locale=en_us
Save the sysidcfg file, and exit your edit session.
Step #3
Rules
Create a directory to hold the rules file if this directory does not already exist. Usually, the /export/config directory holds the rules file.
mkdir /export/config
Change the directory to /export/config, and create a file called rules using a text editor.
cd /export/config
vi rules
In the rules file, add the following line:
hostname client_name - profile1 -
For client_name, substitute the name of your JumpStart client. For example:
hostname sun1 - profile -
Save the rules file, and exit your edit session.
Profiles
Usually, the /export/config directory holds the profile file.
Change the directory to /export/config, and create a file called profile using a text editor.
cd /export/config
vi profile1
Add the following lines to the profile1 file:
install_type initial_install
system_type standalone
partitioning explicit
filesys c0t0d0s0 free /
filesys c0t0d0s1 128 swap
cluster SUNWCXall
Save the profile1 file, and exit your edit session.
Step #4
Before a JumpStart client can use a configuration provided by a JumpStart server, you must run the check script to produce a file called rules.ok. The check script validates the syntax of the rules file and the profile files. If the validation completes successfully, the check script creates the rules.ok file. Change the directory to the location of the check script.
cd /export/install/Solaris_10/Misc/JumpStart_sample
Copy the check script to the /export/config directory.
cp check /export/config
Change the directory to /export/config, and run the check script.
cd /export/config
./check
Validating rules...
Validating profile profile1...
The custom JumpStart configuration is ok.
Step #5
Add a host entry
Edit the /etc/ethers file, and add an entry for the JumpStart client.
vi /etc/ethers
00-C0-26-84-34-A1 sun1
Save and exit from the ethers file.
Edit the /etc/inet/hosts file, and add an entry for the JumpStart client.
vi /etc/inet/hosts
192.168.1.1 sun1
Save and exit from the hosts file.
Add a client
Change the directory to the location of the add_install_client script on the server.
cd /export/install/Solaris_10/Tools
Run the add_install_client script, and specify server and client information as follows. (Note: The following line of code should all be entered on one line.)
./add_install_client -c server_name:/export/config \
-p server_name:/export/config client_name platform_group
For example:
./add-install-client -c sun:/export/config -p sun:/export/config sun1 sun4u
Edit the /etc/dfs/dfstab file to add the following line:
vi /etc/dfs/dfstab
share -F nfs -o ro, anon=0 /export/install
share -F nfs -o ro, anon=0 /export/config
Save and exit from the dfstab file.
Run the shareall command to share the /export/config and /export/install directories.
shareall
Verify that the /export/config and /export/install directories are currently shared.
share
Step #6
Booting the JumpStart Client
After the JumpStart server has been configured to provide all of the required services, you can initiate the installation process on the JumpStart client. To boot the JumpStart client, perform the
Bring the JumpStart client to run state 0
init 0
Boot the client to initiate the software installation using the JumpStart procedure
ok boot net - install
Configure Jumpstart server
Jump Start Server on Solaris 10 Sparc
First of all insert Solaris 10 DVD into Jumpstart server
Jumpstart server details:
Hostname : vcssun108 IP : 10.212.107.18

Make a directory where we can dump DVD image
mkdir –p /export/install/sparc_10
Change directory to
cd /cdrom/cdrom0/s0/Solaris_10/Tools/
./setup_install_server /export/install/sparc_10
touch /etc/bootparams
Above command will dump Solaris 10 image into /export/install/sparc_10 directory
