Jumpstart

Jumpstart server in Solaris enables installation of OS over network to multiple range of servers differing in architecture ,softwares, packages, disk capacity etc .The process consists of setting up of a boot server/install server with OS media image and jumpstart client configurations and connecting clients through network .

Three specific types of services are required for a successful JumpStart installation. These services, which can be provided from one or multiple servers, are boot, profile, and install.

JumpStart Boot Server
The JumpStart boot server provides the services most critical to a successful JumpStart installation and supplies the following information:

  1. IP address of the client
  2. IP address(es) of both the JumpStart profile and install servers

A JumpStart boot server does not have to be a separate server from the profile and install servers. However, it may have to be a separate server when using RARP to provide the IP address to a JumpStart client. The RARP protocol is not a routed protocol, so RARP requests are not forwarded by routers between subnets.

JumpStart Profile Server
One of the major benefits of JumpStart technology is the ability to automate system installations so the installation occurs without any human intervention.

This configuration information can be provided through several different mechanisms. The minimum amount of information required, to automate a JumpStart installation, is the following:

  • System locale
  • Time zone
  • Netmask
  • IPv6
  • Terminal type
  • Security policy
  • Name service
  • Timeserver

If any of this information is not provided through either the configuration files on the profile server (for example, a sysidcfg file), or through a name service, the JumpStart installation defaults to an interactive installation.

A JumpStart profile server provides the configuration information needed by a JumpStart client so that the JumpStart installation can continue without any requests for additional information. With the add_install_client command, specify the profile server to be used and a fully qualified path to the sysidcfg file. This command runs on the JumpStart boot server.
