Sun N1 System Manager 1.1 Administration 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 in documentation. 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 command with the osprofile keyword and the os subcommand. OS profiles must specify a distribution group, partition configuration information, and a root password. To add required distribution groups to the OS profile, use the add command with the osprofile keyword and the distributiongroup subcommand. To add partitions to an OS profile, use the add command with the osprofile keyword and the partition subcommand. For example:


N1-ok> create osprofile osprofile os os


N1-ok> add osprofile osprofile partition partition


N1-ok> add osprofile osprofile distributiongroup distributiongroup

To modify existing OS profile attributes, use the set command with the osprofile keyword and an appropriate subcommand.

For syntax and parameter details, type help create osprofile, help add osprofile or help set osprofile at the N1–ok command line.

See Example 3–5 and Example 3–6 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.

If you want to use the default profile to provision servers other than V20z models, you need to modify the default profile. Instead, you could 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.

The following is a list of best practices for modifying default OS profiles:

Example 3–5 Creating a Solaris OS Profile Through the Command Line

The following example illustrates the commands that are used to create an OS profile for a Solaris OS distribution. The first command creates a Solaris 10 profile that is named S10profile and sets the root password to admin.


N1-ok> create osprofile S10profile rootpassword admin 
description "S10 for host123" os solaris10

The following example command shows how to configure a swap partition with a size of 2048 Mbytes:


N1-ok> add osprofile s10profile partition / size 2048 device c1t1d0s1 
type swap

The following example command shows how to configure a free ufs partition:


N1-ok> add osprofile s10profile partition / sizeoption free device c1t1ds0 
type ufs

The following example command shows how to add the default Solaris distribution group:


N1-ok> add osprofile s10profile distributiongroup "Entire Distribution plus OEM support"

OS profiles that install only the Core System Support distribution group cannot be monitored by using the OS monitoring feature.

ProcedureTo Clone an Existing OS Profile

The following procedure describes how to clone or copy an existing OS profile. You might want to clone an existing OS profile if you need to modify it, but cannot do so because it is deployed. A deployed OS profile is a profile that is currently being installed on a provisionable server.

Before You Begin

Move any file systems off the /mnt mount point.

Steps

  1. Log in to the N1 System Manager.

    See To Access the N1 System Manager Command Line for details.

  2. Type the following command:


    N1-ok> create osprofile osprofile clone oldprofile

    The new OS profile is created. See create osprofile in Sun N1 System Manager 1.1 Command Line Reference Manual

  3. Type the following command:


    N1-ok> show osprofile osprofile

    The new OS profile appears in the output.

ProcedureTo Modify an OS Profile

This procedure describes how to modify the scripts, partitions, updates, and distribution groups that are configured for an OS profile.

Note –

An OS profile that is currently being deployed cannot be modified.

Steps

  1. Log in to the N1 System Manager.

    See To Access the N1 System Manager Command Line for details.

  2. Modify an OS profile by performing one of the following actions:

  3. View the new OS profile details.


    N1-ok> show osprofile osprofile

    The modified OS profile information appears in the output.

Example 3–8 Modifying an OS Profile Through the Command Line

This example shows how to use a flash archive and a post-installation script by modifying the solaris_ver10 OS profile.

For this example, assume that you have created and made available to the management server's /etc/sysconfig/network-scripts directory, the following script to configure the provisionable server's bge1 data network interface. This sample script will configure the bge1 port at system boot time by using the data network DHCP server.


DEVICE=bge1
BOOTPROTO=dhcp
ONBOOT=yes

This example also assumes that you have created a flash archive file called archive1.flar and that you have completed the steps in To Copy a Flash Archive to the Management Server.

The following example shows how to add the script to the OS profile.


N1-ok> add osprofile solaris_ver10 script 
/etc/sysconfig/network-scripts/ifcfg-bge1 type post

The following example shows how to setup the OS profile to use the flash archive.


N1-ok> set osprofile solaris_ver10 flar /jumpstart/Flash/archive1.flar
