Sun N1 System Manager 1.1 Administration Guide

Introduction to Server and Group Management

The N1 System Manager enables you to manage hundreds of heterogeneous servers by using one interface. The N1–ok shell provides a simple command set with which to identify, manage, provision, and reprovision servers.

You can use the discover command to initiate the management of provisionable servers. The server discovery process creates a Discovery job in the N1 System Manager. The Discovery job uses the management IP address and default security credentials to identify each physical server. You can view the job results to track the discovery process.

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.

The sections in this chapter describe the prerequisites and instructions for performing server and server group maintenance tasks. You will use the View Selector menu, the Actions menu, and server name links to perform the operations that are described in these sections.

The following graphic shows the View Selector menu, the Actions menu, and the server name links.
