Sun N1 System Manager 1.3 Operating System Provisioning Guide

Introduction to Managing OS Updates

After you have installed an OS on a managed server, the N1 System Manager enables you to install OS updates. These OS updates consist of Solaris packages and patches and Linux RPMs.

Note –

The N1 System Manager does not enable you to install updates or patches for the Windows operating system. You must update the Windows operating system on a managed server outside of the Sun N1 System Manager environment.

Installing OS updates on servers for the first time involves the following four-step process when you use the N1 System Manager:

  1. Downloading the OS update.

  2. Copying the OS update to the N1 System Manager.

    The N1 System Manager must have system access to the OS update before the update can be installed on the managed servers.

    By using the create update command, you can copy an OS update from a web site or an accessible file system on the management server. After an OS update is copied, you can display the update in the browser interface's Task Shortcuts pane, or you can use the show update command.

  3. Verifying that the OS update was copied by displaying the Shortcut in the browser interface or by using the show update command.

  4. Installing the OS update on the appropriate managed servers by using the browser interface or the load server or load group commands. The managed servers must have the base management feature supported.

OS update installations behave differently for every operating system because the native package installation mechanisms are used. For example, if a Solaris package is already installed on the target server, the installation might succeed without reporting an error. However, this same scenario for a Linux RPM results in an error message indicating that the package is already installed.

See OS Updates in Sun N1 System Manager 1.3 Troubleshooting Guide for troubleshooting information.

The following graphic describes the order in which these tasks should be completed.

This graphic illustrates the steps to update an OS.

Installing Custom OS Updates

The N1 System Manager also enables you to install OS updates that don't use the standard patch, package, or RPM update commands, such as .tgz, .tar, .Z, or .zip files. Examples of files you can install include:

The overall process to copy and install standard OS updates using N1 System Manager is the same for custom OS updates, with the following exceptions:

Installation Script Overview

When copying an OS update using the create update command, you can specify an installation script with the installscript attribute. Installation scripts are used to install an OS update and are available for the following scenarios:

The following information provides instructions on how to create a successful installation script for either standard or custom OS update installations:

Installing Multiple Solaris Packages

When you install a standard OS update that contains multiple Solaris packages in a tar file, follow these guidelines:

When you install a custom OS update that contains multiple Solaris packages in a tar file, follow these guidelines:
