Jumpstart Solaris

How To clone our Solaris Sun boxes:

Create flash-archive

 flarcreate -n "s01 flash" -c -R / -x /atlashome /atlashome/carsten/s01.flar

Our configuration

Currently s05 is our testing Jumstart-Server. Edit Template-file /root/bin/jet_template and edit e.g. flash_archive_locations (cf. JET). Use the script

 /root/bin/set_boot.sh jumpstart s11 

to activate jumpstart for s11 (node must be in dhcpd.conf of our dhcp-server). Reboot s11 and set bios-boot-devices first to net-boot. After 15 minutes s11 should be installed.

TODO: Boot from 10G-card? Create final flash-image? Updates via flash differential-archives?

Jumpstart-Enterprise-Toolkit (JET)

A good tutorial can be found here: http://wiki.c0t0d0s0.org/index.php?title=JumpstartTutorial

• Download an install JET: /opt/SUNWjet/ contains all the tools you need
• Copy install media via /opt/SUNWjet/copy_solaris_media cdrompath... to /export/home/install and share this directory
• Create template ./make_template sXY custom sds flash
• Edit /opt/SUNWjet/Templates/sXY:

• Make: "./make_client -f sXY"
• The important Jumpstart-files are stored in /opt/SUNWjet/Clients/sXY, like "sysidcfg" and "profile".
• Enable TFTP in /etc/inetd.conf and restart inetd with svcadm
• Edit /tftpboot/boot/grub/menu.lst which should look like

default=0
timeout=30
title Solaris_10 Jumpstart
        kernel /I86PC.Solaris_10-1/multiboot kernel/unix - install -B install_config=10.20.20.5:/opt/SUNWjet,sysid_config=10.20.20.5:/opt/SUNWjet/Clients/s11,install_media=10.20.20.5:/export/home/install/media/Solaris_10,install_boot=10.20.20.5:/export/home/install/media/Solaris_10/boot
        module /I86PC.Solaris_10-1/x86.miniroot

• Take care to add the - install between "kernel/unix" and "-B ...". This argument enables "Custom Jumpstart" - otherwise system will per default boot into an interactive menu (options "text" or "nowin"). This may be a bug in Jumpstart...
• Add the following lines to dhcpd.conf on your dhcp-server for your Jumpstart-Clients:

  next-server 10.20.20.5;
  filename "pxegrub.I86PC.Solaris_10-1";

• Reboot client and choose netboot during start...

Ideas:

• Wrong entries in sysidcfg will cause the start of an interactive installation. E.g. the "root_password"-entry must not be too long.
• Instead of /tftpboot/boot/grub/menu.lst pxegrub first looks for /tftpboot/menu.lst.01. Here we can place a custom boot-menu
• Use custom_scripts_f to execute a script afer jumpstart-installation (e.g. for disabeling the installation boot-menu)

Jumpstart

If you dont want to use JET you can easily do such things by hand:

Create and export the Jumpstart/Installation-directory e.g. "/jumpstart" and make sure that nfs-options are set to "ro,anon=0". Then copy the installation-media-files to your harddisk:

 # e.g. mount the image
 lofiadm -a /tmp/sol-nv-b79b-x86-dvd.iso /dev/lofi/1
 mount -F hsfs -o ro /dev/lofi/1 /mnt
 # and copy files via
 /mnt/Solaris_11/Tools/setup_install_server /jumpstart/solaris_installation

In fact this may be not necessary for we just want to do flash installation.

Then youve got to create Jumpstart-configuration files:

/jumpstart/rules

 hostname s11   test_begin   test_profile  -
 # or
 any -   test_begin   test_profile  -

/jumpstart/test_profile

 # profile keywords      profile values
 # ----------------      -------------------
 install_type            flash_install
 archive_location        nfs 10.20.20.3:/rz2pool/flash/archive1s09_.flar
 partitioning            explicit
 filesys                 c5t0d0s0 20652 /
 filesys                 c5t0d0s1 2000 swap

What about creating pre and post-install-scripts: /jumpstart/test_begin

Then execute ./check and rules.ok is createt if syntax is ok.

/jumpstart/sysidcfg

 system_locale=en_US
 timezone=MET
 timeserver=localhost
 network_interface=primary {netmask=255.255.255.0 protocol_ipv6=no}
 terminal=vt100
 nfs4_domain=dynamic
 security_policy=NONE
 name_service=NONE
 service_profile=limited_net
 root_password=changeme

Execute:

 cd /jumpstart/solaris11/Solaris_11/Tools/
 ./add_install_client -i 10.20.20.11 -p 10.20.20.3:/jumpstart/ -c 10.20.20.3:/jumpstart/ s11 i86pc

Enable TFTP and make sure that /tftpboot/boot/grub/menu.lst

default=0
timeout=30
title Solaris_11 Jumpstart
        kernel /I86PC.Solaris_11-1/platform/i86pc/kernel/unix -B install_config=10.20.20.3:/jumpstart/,sysid_config=10.20.20.3:/jumpstart/,install_media=10.20.20.3:/jumpstart/solaris11
        module /I86PC.Solaris_11-1/x86.miniroot

Then reboot and choose netboot during start...
