JET/Jumpstart x86 pxe notes

This is just a quick note, probably most useful for myself that I've gathered while setting up a pile of X4100s.

• Download and install JumpStart Enterprise Toolkit 4.3.2. You don't need to install all of it, but is is small enough that I did. I'll assume it goes to /opt/SUNWjet
• # export PATH=$PATH:/opt/SUNWjet/bin
• I'll assume the following:
• • Solaris 10 update 2
  • You've got the dvd iso sol-10-u2-ga-x86-dvd.iso in /export
  • You're putting your files in /export/install
• # copy_solaris_media -d /export/install/s10u2 -n s10u2 -i /export sol-10-u2-ga-x86-dvd.iso

• Created loopback device /dev/lofi/1 for /export/sol-10-u2-ga-x86-dvd.iso
  mounted /export/sol-10-u2-ga-x86-dvd.iso at /export/install/1389/slices/s0 (of type hsfs)
  Copying Solaris image....
  Verifying target directory...
  Calculating the required disk space for the Solaris_10 product
  Calculating space required for the installation boot image
  Copying the CD image to disk...
  Copying Install Boot Image hierarchy...
  Copying /boot x86 netboot hierarchy...
  Install Server setup complete
   
  Added Solaris image s10u2 at the following location:
          Media:          /export/install/s10u2
   
  Unmounting /export/install/1389/slices/s0
  removing device /dev/lofi/1
  removing directory /export/install/1389
  

• Install a dhcp server:
• # pkgadd -d /export/install/s10u2/Solaris_10/Product SUNWdhcsr SUNWdhcsu SUNWdhcm SUNWdhcsb
• # dhcpconfig -D -r SUNWfiles -p /var/dhcp

• Created DHCP configuration file.
  Created dhcptab.
  Added "Locale" macro to dhcptab.
  Added server macro to dhcptab - n1master.
  DHCP server started.
  

• Set up dhcp - assuming:
• • NETWORK: 192.168.1.0
  • NETMASK: 255.255.255.0
  • ROUTER: 192.168.1.1
• # dhcpconfig -N 192.168.1.0 -m 255.255.255.0 -t 192.168.1.1
• # make_template x4100

• Adding product configuration information for 
          + base_config
          + custom
          + sds
          + vts
          + explo
          + flash
          + san
          + jass
          + zones
  Updating base_config template specifics
  Client template created in /opt/SUNWjet/Templates
  

• At this point JET automatically adds nfs shares - I had to tweak mine so that I have:
• # share -F nfs -o ro,anon=0 -d "JET Framework" /opt/SUNWjet
• # share -F nfs -o ro,anon=0 /export/install/
• # cd /opt/SUNWjet/Templates
• Edit the template to fit your needs - at the bare minimum, you need to set:
• • base_config_ClientArch=
  • base_config_ClientOS=
  • base_config_client_allocation=
  • base_config_ClientEther=
  • base_config_sysidcfg_network_interface=
  • base_config_sysidcfg_netmask=
  • base_config_sysidcfg_default_route
  • base_config_sysidcfg_ip_address
• This could look something like:

• base_config_ClientArch=i86pc
  base_config_ClientEther=00:14:4F:2A:XX:XX
  base_config_ClientOS=s10u2
  base_config_client_allocation="grub"
  base_config_sysidcfg_network_interface=e1000g0
  base_config_sysidcfg_ip_address=192.168.1.3
  base_config_sysidcfg_netmask=255.255.255.0
  base_config_sysidcfg_default_route=192.168.1.1
  

• Other common things to change would be the root passwd (see comment in the profile), disk layout and what cluster to use.An example diff for the interesting bits of the disk layout could look like this:

• I usually choose either the full or the restricted net install:

• base_config_profile_cluster=SUNWCXall
  base_config_profile_cluster=SUNWCreq
  

• make_client -f x4100

• And that's all there is to it - for the X4100, you'll have to press F12 during startup to force a network install. On a local net, the install time for SUNWCreq is about 15 minutes on an X4100

Next installments could be to use flash install, setting up JASS and zones, adding patches and extra packages.
