Sun N1 System Manager 1.1 Administration Guide

Creating and Maintaining Server Groups

This section describes the following tasks:

Creating Groups and Adding Servers to Groups

After successful completion of the Discovery job, a server is identified by its management name. The server's management name is initially set to the server's management IP address. You can rename discovered servers at any time.

You can create groups of discovered, or provisionable, servers according to the make and model for aggregate installation of firmware updates. Then, you can create functional groups for the aggregate installation of operating systems, or OS profiles, and OS updates. Provisionable servers can belong to more than one server group, so you can create new server groups for aggregate maintenance tasks, as needed.

To create server groups, you use the create command with the group keyword. To add servers to a group, you use the add command with the group keyword and the server subcommand.

To create a group and add servers in a single operation, you use the create command with the group keyword and the server subcommand. This task can also be performed during the discovery process. To do so, you can add an option to the discover command to create a new group and add the servers to the new group. See To Discover New Servers for instructions.

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

To Create a Server Group

This task shows you how to create groups of discovered, or provisionable, servers. Provisionable servers can belong to more than one server group, so you can create new server groups for aggregate maintenance tasks, as needed.

Steps

N1-ok> create group group
The new group is created. See create group in Sun N1 System Manager 1.1 Command Line Reference Manual for details.

Example 2–3 Creating a Group and Adding Servers in a Single Operation

The following example shows how to create a group named dev and add servers named server1 and server2. Then, the show group command output provides the list of servers in the dev group.

N1-ok> create group dev server server1,server2
N1-ok> show group dev
Name		Hardware	Power		Health		OS Usage  	
server1   	V20z       On       	Good		   --			  
server2   	V20z       On       	Good         RH30
