Sun N1 System Manager 1.3 Operating System Provisioning Guide

Managing OS Profiles

This section describes the following tasks:

Creating, Listing, and Modifying OS Profiles

OS profiles specify the following information:

After you have copied an OS distribution, the N1 System Manager automatically creates an OS profile of the same name on the management server. This OS profile is also called a default OS profile. See Default OS Profiles for parameter settings and best practices for customizing OS profiles.

To view details of a default OS profile, use the show command with the osprofile keyword.

To create a new OS profile, use the create osprofile, add osprofile, and set osprofile commands. See Example 2–6 and Example 2–7 for command-line examples.

Default OS Profiles

When you copy an OS distribution, a default OS profile is automatically created for the OS distribution. The default profile is created for a typical Sun Fire V20z server, and it is mainly provided as an example. Settings for the default OS profiles are described in the following table.

Best Practices for Modifying Default OS Profiles

To provision servers other than Sun Fire V20z servers, you need to modify the default profile, create a new OS profile, or clone an existing OS profile and customize the parameter settings. Each server at your site with different hardware and provisioning requirements requires the creation of a customized OS profile.

The browser interface provides a wizard for creating new OS profiles to limit the complexity of this operation. See To Create an OS Profile for instructions.

Some best practices for modifying default OS profiles are:
