Introduction

Overview

Server Administrator provides a comprehensive, one-to-one systems management solution in two ways: from an integrated, Web browser-based graphical user interface (GUI) and from a command line interface (CLI) through the operating system. Server Administrator is designed for system administrators to manage systems locally and remotely on a network. Server Administrator allows system administrators to focus on managing their entire network by providing comprehensive one-to-one systems management.

NOTE: For the purposes of Server Administrator, a system can be a stand-alone

system, a system with attached network storage units in separate chassis, or a modular system consisting of one or more server modules in a modular enclosure.

Server Administrator provides information about:

• Systems that are operating properly and systems that have problems

• Systems that require remote recovery operations

NOTE: For remote recovery, a Dell™ Remote Access Controller must be installed.

Integrated Features

Server Administrator provides easy-to-use management and administration of local and remote systems through a comprehensive set of integrated management services. Server Administrator is the sole installation on the system being managed and is accessible both locally and remotely from the Server Administrator home page. Remotely monitored systems may be accessed by dial-in, LAN, or wireless connections. Server Administrator ensures the security of its management connections through role-based access control (RBAC), authentication, and industry-standard secure socket layer (SSL) encryption.

Introduction 11

Installation

You can install Server Administrator using several methods. The Dell™ Systems Management Tools and Documentation DVD provides a setup

program to install, upgrade, and uninstall Server Administrator and other managed system software components on your managed system. This DVD also provides a setup program to install, upgrade and uninstall management station software components on your management station. Additionally, you can install Server Administrator on multiple systems through an unattended installation across a network.

NOTE: If you have a modular system, you must install Server Administrator on each

server module that is installed in the chassis.

NOTE: For more information on unattended Server Administrator

installation/uninstallation see the Dell OpenManage™ Installation and Security User's Guide.

To update individual system components, use component-specific Dell Update Packages. Use the Dell Server Updates DVD to view the complete version report and to update an entire system. The Server Update Utility is a DVD-ROM–based application for identifying and applying updates to your server. The Server Update Utility can be downloaded from support.dell.com.

See the Server Update Utility User's Guide for more information about obtaining and using the Server Update Utility (SUU) to update your Dell Systems or to view the updates available for any systems listed in the Repository.

Server Administrator Home Page

The Server Administrator home page provides easy-to-set up and easy-to-use Web browser-based system management tasks from the managed system or from a remote host through a LAN, dial-up service, or wireless network. When the Dell Systems Management Server Administrator Connection Service (DSM SA Connection Service) is installed and configured on the managed system, you can perform remote management functions from any system that has a supported Web browser and connection. Additionally, the Server Administrator home page provides extensive, context-sensitive online help.

12 Introduction

Instrumentation Service

The Instrumentation Service provides rapid access to detailed fault and performance information gathered by industry-standard systems management agents and allows remote administration of monitored systems, including shutdown, startup, and security.

Remote Access Controller

NOTE: The Remote Access Controller is not available on modular systems. You

must directly connect to the Dell Embedded Remote Access/Modular Chassis Controller (ERA/MC) on a modular system. See the Dell Embedded Remote Access/MC User's Guide for more information.

The Remote Access Controller provides a complete, remote system management solution for systems equipped with a Dell Remote Access Controller (DRAC) solution. The Remote Access Controller provides remote access to an inoperable system, allowing you to get the system up and running as quickly as possible. The Remote Access Controller also provides alert notification when a system is down and allows you to remotely restart a system. Additionally, the Remote Access Controller logs the probable cause of system crashes and saves the most recent crash screen.

Storage Management Service

The Storage Management Service provides storage management information in an integrated graphical view.

The Storage Management Service of Server Administrator:

• Enables you to view the status of local and remote storage attached to a monitored system

• Supports SCSI, SATA, ATA, and SAS. Does not support Fibre Channel

• Allows you to perform controller and enclosure functions for all supported RAID and non-RAID controllers and enclosures from a single graphical or command line interface without the use of the controller BIOS utilities

• Protects your data by configuring data redundancy, assigning hot spares, or rebuilding failed drives

• Provides features for configuring storage

Introduction 13

On supported Microsoft® Windows® operating systems, Storage Management is installed using the Typical Setup.

On systems running supported Red Hat

Enterprise Linux® and SUSE® Linux Enterprise Server operating systems, you can either install the Storage Management Service through the Red Hat Package Manager (RPM) or use the srvadmin-install.sh script—a menu driven script that installs the appropriate RPMs based on the options you choose.

For more information on the Storage Management Service, see the Storage Management online help and the Dell OpenManage Server Administrator Storage Management User's Guide. For information on how to launch the online help, see "Displaying Online Help".

NOTICE: Dell OpenManage Array Manager is no longer supported. If you are

upgrading a system (installed with Dell OpenManage version 4.3 or later) with Array Manager installed, Array Manager will be removed during the upgrade process. You can use Storage Management instead.

NOTE: Installing Storage Management replaces any previous installation of the

Array Manager managed system (server software) and console (client software) on the system. If only the Array Manager console is installed on the system, then installing the Storage Management does not replace the Array Manager console.

NOTE: Dell OpenManage Array Manager Console (for Management Station) is

available under Windows, only if previous Dell OpenManage Management Station software (with Array Manager Console installed) is detected. It is only available for upgrade.

Logs

Server Administrator displays logs of commands issued to or by the system, monitored hardware events, and system alerts. You can view logs on the home page, print or save them as reports, and send them by e-mail to a designated service contact.

20 What’s New for Version 5.5

Setup and Administration

Security Management

Server Administrator provides security through role-based access control (RBAC), authentication, and encryption for both the Web-based and command line interfaces.

Role-Based Access Control

RBAC manages security by determining the operations that can be executed by persons in particular roles. Each user is assigned one or more roles, and each role is assigned one or more user privileges that are permitted to users in that role. With RBAC, security administration corresponds closely to an organization's structure.

User Privileges

Server Administrator grants different access rights based on the user's assigned group privileges. The three user levels are: User, Power User, and Administrator.

•

Users

can view most information.

Power Users

• actions are to be taken when a warning or failure event occurs.

•

Administrators

22 Setup and Administration

Authentication

The Server Administrator authentication scheme ensures that the correct access types are assigned to the correct user privileges. Additionally, when the command line interface (CLI) is invoked, the Server Administrator authentication scheme validates the context within which the current process is running. This authentication scheme ensures that all Server Administrator functions, whether accessed through the Server Administrator home page or CLI, are properly authenticated.

Microsoft Windows Authentication

For supported Microsoft® Windows® operating systems, Server Administrator authentication uses Integrated Windows Authentication (formerly called NTLM) to authenticate. This authentication system allows Server Administrator security to be incorporated in an overall security scheme for your network.

Red Hat Enterprise Linux and SUSE Linux Enterprise Server Authentication

For supported Red Hat® Enterprise Linux® and SUSE® Linux Enterprise Server operating systems, Server Administrator uses various authentication methods based on the Pluggable Authentication Modules (PAM) library. Users can log in to Server Administrator either locally or remotely using different account management protocols, such as LDAP, NIS, Kerberos, and Winbind.

NOTE: Server Administrator authentication using Winbind and Kerberos on SUSE

Linux Enterprise Server (Version 9 Service Pack 3) is not supported because the 32-bit compatible libraries for Winbind and Kerberos are not present in the operating system.

Encryption

Server Administrator is accessed over a secure HTTPS connection using secure socket layer (SSL) technology to ensure and protect the identity of the system being managed. Java Secure Socket Extension (JSSE) is used by supported Microsoft Windows, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server operating systems to protect the user credentials and other sensitive data that is transmitted over the socket connection when a user accesses the Server Administrator home page.

Setup and Administration 23

Assigning User Privileges

To ensure critical system component security, assign user privileges to all

™

OpenManage™ software users before installing Dell OpenManage

Dell software. New users can log into Dell OpenManage software using their operating system user privileges.

NOTICE: To protect access to your critical system components, assign a password

to every user account that can access Dell OpenManage software. Users without an assigned password cannot log into Dell OpenManage software on a system running Windows Server 2003 due to the operating system design.

NOTICE: Disable guest accounts for supported Windows operating systems to

protect access to your critical system components. Consider renaming the accounts so that remote scripts cannot enable the accounts using the name.

NOTE: For instructions on assigning user privileges for each supported operating

system, see your operating system documentation.

NOTE: Add new users to the operating system if you want to add users to

OpenManage software. You do not have to create new users from within the OpenManage software.

Adding Users to a Domain on Windows Operating Systems

NOTE: You must have Microsoft Active Directory® installed on your system to

perform the following procedures. See "Microsoft Active Directory" for more information about using Active Directory.

Configuring the SNMP Agent

Server Administrator supports the Simple Network Management Protocol (SNMP)—a systems management standard—on all supported operating systems. The SNMP support may or may not be installed depending on your operating system and how the operating system was installed. In most cases, SNMP is installed as part of your operating system installation. An installed supported systems management protocol standard, such as SNMP, is required before installing Server Administrator. See "Installation Requirements" for more information.

28 Setup and Administration

You can configure the SNMP agent to change the community name, enable Set operations, and send traps to a management station. To configure your SNMP agent for proper interaction with management applications such as the Dell OpenManage™ IT Assistant, perform the procedures described in the following sections.

NOTE: The default SNMP agent configuration usually includes a SNMP community

name such as public. For security reasons, change the SNMP community names from their default values. For information about changing SNMP community names, see the appropriate section below. For additional guidelines, see the Securing an SNMP Environment article, dated May 2003, in the Dell Power Solutions magazine. This magazine is also available at www.dell.com/powersolutions.

NOTE: SNMP Set operations are disabled by default in Server Administrator

version 5.2 or later. Server Administrator provides support to enable or disable SNMP Set operations in Server Administrator. You can use the Server Administrator SNMP Configuration page under Preferences or the Server Administrator command line interface (CLI) to enable or disable SNMP Set operations in Server Administrator. For more information about the Server Administrator CLI, see the Dell OpenManage Server Administrator Command Line Interface User's Guide.

NOTE: For IT Assistant to retrieve management information from a system running

Server Administrator, the community name used by IT Assistant must match a community name on the system running Server Administrator. For IT Assistant to modify information or perform actions on a system running Server Administrator, the community name used by IT Assistant must match a community name that allows Set operations on the system running Server Administrator. For IT Assistant to receive traps (asynchronous event notifications) from a system running Server Administrator, the system running Server Administrator must be configured to send traps to the system running IT Assistant.

The following procedures provide step-by-step instructions for configuring the SNMP agent for each supported operating system:

• "Configuring the SNMP Agent for Systems Running Supported Windows Operating Systems"

• "Configuring the SNMP Agent on Systems Running Supported Red Hat Enterprise Linux"

• "Configuring the SNMP Agent on Systems Running Supported SUSE Linux Enterprise Server Operating Systems"

Configuring the SNMP Agent for Systems Running Supported Windows Operating Systems

Server Administrator uses the SNMP services provided by the Windows SNMP agent. You can configure the SNMP agent to change the community name, enable Set operations, and send traps to a management station. To configure your SNMP agent for proper interaction with management applications such as IT Assistant, perform the procedures described in the following sections.

NOTE: See your operating system documentation for additional details on SNMP

configuration.

Enabling SNMP Access By Remote Hosts

Windows Server 2003, by default, does not accept SNMP packets from remote hosts. For systems running Windows Server 2003, you must configure the SNMP service to accept SNMP packets from remote hosts if you plan to manage the system by using SNMP management applications from remote hosts.

To enable a system running the Windows Server 2003 operating system to receive SNMP packets from a remote host, perform the following steps:
