Thanks, Richard Coleman coleman@math.gatech.edu ------- Forwarded Message HOW TO CONFIGURE Solaris 2.x to jumpstart SunOS_4.1.4 ===================================================== WRITTEN 02/24/95 Robert Kohler (robert.kohler@uprc.com) UPDATED 06/20/95 Robert Kohler (robert.kohler@uprc.com) Purpose: I have searched for a way to install SunOS_4.1.4 with minimal to no intervention. I pondered various scenarios, and finally succeeded. 1: I first tried to make a boot floppy, which would boot into an OS, then run my preconfigured scripts which would install the SunOS_4.1.4 over the network onto the internal disk. After trying this myself and from various responses from the sun-managers mailing list, I concluded that SunOS_4.1.4 will not fit in 1.44MB of floppy disk space. If you want the details, please send a request to robert.kohler@uprc.com. 2: Second try involved Configuring Solaris 2.x JumpStart to install SunOS_4.1.4 for me. This would eliminate the need for a floppy disk. After several trial and error scenarios, I feel I have created one of the best ways to install SunOS_4.1.4 over the net. NOTE: Current delimna is the fact that each machine we install must be on the same subnet. This is because we filter broadcasts on our routers. This can be remedied, will discuss later. Details: 1. Install Solaris 2.x JumpStart onto an install server. NOTE: Mount Solaris 2.x CD, and run "add_install_server". We are using a SparcLX currently. (named "grunt"), and installed it into the following directory.. /usr/export/data2/install_images NOTE: Don't need Solaris 2.x CD anymore. 2. Now you must install from CD your first SunOS_4.1.4 system. Install it exactly as you want using suninstall. Perform all configurations so that it will work on your network. We need this image to "dump" to our install server (grunt). We configured the following on our 207MB internal drives. Packages include: root usr Kvm Install Networking System_V Sys Text OpenWindows_Users OpenWindows_Fonts Security Disk layout is as follows: Current partition table (original sd0): partition a - starting cyl 0, # blocks 20736 (64/0/0) partition b - starting cyl 64, # blocks 65772 (203/0/0) partition c - starting cyl 0, # blocks 406296 (1254/0/0) partition d - starting cyl 0, # blocks 0 (0/0/0) partition e - starting cyl 0, # blocks 0 (0/0/0) partition f - starting cyl 0, # blocks 0 (0/0/0) partition g - starting cyl 267, # blocks 319788 (987/0/0) partition h - starting cyl 0, # blocks 0 (0/0/0) NOTE: partition a is / 10MB partition b is swap 32MB partition g is /usr REMAINING 3. Back on install server (grunt), make a sub-directory tree for images. We set up the following... grunt:/usr/export/data2/os_images/SunOS_4.1.4/sun4c/GENERIC I made a link for /os to point to /usr/export/data2/os_images so our scenario now looks like the following. grunt:/os/${OS_VERSION}/${ARCHITECTURE}/${KERNEL} Inside each kernel directory will be 2 files root and usr (dump images of the original SunOS_4.1.4 configured). NOTE: I chose dump/restore for it's flexibility of partition sizes and disk sizes. 4. Now it is time to dump the SunOS_4.1.4 install image of the preconfigured machine to the install server. Using NFS, we can "cd /data/grunt2/os/SunOS_4.1.4/sun4c/GENERIC which is actually "grunts" disk. From here we run the following command. "dump 0dsf 54000 13000 root /dev/rsd0a" "dump 0dsf 54000 13000 usr /dev/rsd0g" This will make 2 files on the install server (root and usr) which sould be the same size as the preconfigured machine. 5. Now you need to configure your install server's tftpboot and bootparams area so as to respond to the broadcast from the machine you are installing. Since we use NIS, I had to update our master yp server's ethers database and host database. (ie. the ethers will map Ethernet address of machine to install to hostname, and the hosts database will map hostname to IP address.) Note: you could just edit the local /etc/hosts and /etc/ethers files. Say we want to upgrade machine name "cronkite" which is a sun4c architecture. On install server, cd /usr/export/data2/install_images, you will find a script called "add_install_client". Run "./add_install_client sun4c cronkite" which sets up the following files... /etc/bootparams" and "/tftpboot/*". Here is our /etc/bootparams file. * install_config=grunt:/usr/export/data2/install_images/configs cronkite root=grunt:/usr/export/data2/install_images/export/exec/kvm/sparc.sun4 c.Solaris_2.4 install=grunt:/usr/export/data2/install_images Here is our /tftpboot directory # ls -al /tftpboot total 348 drwxrwxr-x 2 root other 512 Feb 24 16:53 . drwxr-xr-x 29 root root 1024 Feb 24 16:53 .. lrwxrwxrwx 1 root other 26 Feb 24 16:53 905E30C8 -> inetboot.sun4c.Solaris_2.4 lrwxrwxrwx 1 root other 26 Feb 24 16:53 905E30C8.SUN4C -> inetboot.sun4c.Solaris_2.4 - -rwxr-xr-x 1 root other 162932 Feb 24 16:53 inetboot.sun4c.Solaris_2.4 - -rw-r--r-- 1 root other 316 Feb 24 16:53 rm.144.94.48.200 lrwxrwxrwx 1 root other 1 Feb 24 16:53 tftpboot -> . The files of interest are the 905E30C8 which is the IP address translated into HEX, and the inetboot.sun4c.Solaris_2.4 which is the boot program for Solaris_2.4. Also, the "add_install_client" will start a daemon called "bootparamd" which will respond to boot net broadcasts. 6. Now make a configuration directory. We made the following grunt:/usr/export/data2/install_images/configs This holds the info on how JumpStart reacts to the boot. (ie. what to install where). Copy the auto_install_sample directory into the configs area. Edit the file "rules", at the bottom add an entry like the following... hostname cronkite && karch sun4c pre_install_4.x 207MB.SunOS_4 post_install_4.x This means if the machine booting is named "cronkite" and the "arch -k" returns "sun4c" then run the "pre_install" script, then the 207MB.SunOS_4 configuration, then the "post_install" script. Upon completion, the system automatically reboots. Create the following files: # more pre_install_4.x 207MB.SunOS_4 post_install_4.x | cat :::::::::::::: pre_install_4.x :::::::::::::: #!/bin/sh #==================================================================== # Name: pre_install_4.x Date: 2/24/95 = # Programmer: Robert Kohler E-Mail: robert.kohler@uprc.com = # Language: Bourne Shell = #-------------------------------------------------------------------= # Purpose: This script will run prior to system installation and = # pre-configure the defaultrouter interface.

Now check to ensure your files were made correctly. Run "./check", this should parse the "rules" file, "pre_install_4.x, post_install_4.x, and 207MB.SunOS_4" Upon completion, this makes a "rules.ok" file. 8. Now you are ready to try to install your new system. Plug new system into ethernet connection, and at the ok prompt type 'boot net - install' NOTE: If the system is live, and running (say SunOS_4.1.x) and you want to upgrade to SunOS_4.1.4, then log into that system and run 'reboot "net - install"' as root. 9. System should take 35 minutes for install. It installs core Solaris 2.4 into system, but then I remove it and overwrite with SunOS_4.1.4. Delay of 10 minutes. I have not found a way to install nothing from Solaris_2.4 inside JumpStart. 10. Upon completion remove the machine from the tftp boot area. On install server: (grunt), cd /usr/export/data2/install_images "run rm_install_client cronkite"... 11. Upon first reboot, the inetd wrapper is executed, thus installs all latest patches, rdists pertinent files, and updates motd (message of the day), etc... It removes itself then reboot automatically. Tada, complete... Now for every other system you want to install, 1. Add to hosts database, or (/etc/hosts). 2. Add to ethers database, or (/etc/ethers). 3. Run "add_install_client " 4. Boot using "boot net - install" from prom. If system already on up...run # reboot "net - install" 5. Run "rm_install_client ". ============================================================================= Now to get around the single subnet issue... 1. Go to a new install server on a different subnet. NFS mount the disk from the install server. cd /data/grunt2/install_images run add_install_server script. Put on a machine which is on the other subnet and has 16MB + disk space for each architecture you want loaded. 2. Now run add_install_client via NFS and let it add the clients. If it fails, remember you just need the files listed below... # cat /etc/bootparams * install_config=grunt:/usr/export/data2/install_images/configs cronkite root=grunt:/usr/export/data2/install_images/export/exec/kvm/sparc.sun4 c.Solaris_2.4 install=grunt:/usr/export/data2/install_images # ls -al /tftpboot total 348 drwxrwxr-x 2 root other 512 Feb 24 16:53 . drwxr-xr-x 29 root root 1024 Feb 24 16:53 .. lrwxrwxrwx 1 root other 26 Feb 24 16:53 905E30C8 -> inetboot.sun4c.Solaris_2.4 lrwxrwxrwx 1 root other 26 Feb 24 16:53 905E30C8.SUN4C -> inetboot.sun4c.Solaris_2.4 - -rwxr-xr-x 1 root other 162932 Feb 24 16:53 inetboot.sun4c.Solaris_2.4 - -rw-r--r-- 1 root other 316 Feb 24 16:53 rm.144.94.48.200 lrwxrwxrwx 1 root other 1 Feb 24 16:53 tftpboot -> . 3. Make sure bootparamd is running on the second boot server. 4. Boot the systems on that net as "boot net - install". ============================================================================= NOTE: Additions to be made and suggestions for improvement.... Copy some machine specific files out prior to upgrade/install so that the system can keep its same configuration. (ie. /var/spool/mail/*, /var/spool/calendar/*, /etc/fstab, etc...) Find better work around for subnet restriction. Put everything in pre_install script. This way you wouldn't have to load any of SunOS_5.x to install 4.1.4. This means you would have to partition your disks in the scripts also. Newfs them, etc. I like having the system do it, and the extra 10 minutes is not an issue to us. Maybe future workarounds will bypass this bug, namely putting a "-" as the configuration package doesn't work. ============================================================================= Enjoy!!!
