Introduction 1 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 enables system administrators to manage systems locally and remotely on a network. It enables system administrators to focus on managing their entire network by providing comprehensive one-to-one systems management.

Setup And Administration 2 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 privileges that are permitted to users in that role.

as setting up users, groups, permissions, and roles, configuring user attributes, adding your own certificates, and determining whether you want to use SSL. NOTE: On systems running VMware ESXi Server 5.0 operating system, to login to Server Administrator, all users require Administrator privileges. For information on assigning roles, see the VMware documentation.
Creating Server Administrator Users For Supported Red Hat Enterprise Linux and SUSE Linux Enterprise Server Operating Systems Administrator access privileges are assigned to the user logged in as root. To create users with User and Power User privileges, perform the following steps. NOTE: You must be logged in as root or an equivalent user to perform the following procedures. NOTE: You must have the useradd utility installed on your system to perform the following procedures.
Editing Server Administrator User Privileges On Linux Operating Systems NOTE: You must be logged in as root or an equivalent user to perform the following procedures. 1. 2. Open the omarolemap file located at /opt/dell/srvadmin/etc/omarolemap. Add the following in the file: [Tab][Tab] The following table lists the legend for adding the role definition to the omarolemap file Table 4.
– there are duplicate entries of user names or user groups along with same • You can also use Space as a delimiter for columns instead of [Tab]. Creating Server Administrator Users For VMware ESX 4.X, ESXi 4.X, And ESXi 5.X To add a user to the Users table: 1. Log in to the host using the vSphere Client. 2. Click the Users & Groups tab and click Users . 3. Right-click anywhere in the Users table and click Add to open the Add New User dialog box. 4.
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 • Configuring the SNMP Agent On Systems Running Supported VMware ESX 4.
5. Click the Security tab to add or edit a community name. To add a community name: a) Click Add under the Accepted Community Names list. The SNMP Service Configuration window appears. b) Type the community name of a system that is able to manage your system (the default is public) in the Community Name box and click Add. The SNMP Service Properties window appears. To edit a community name: a) Select a community name in the Accepted Community Names list and click Edit.
(identified by the 1.3.6.1.2.1.1 OID) of the MIB tree. This configuration does not allow management applications to retrieve or change Server Administrator or other systems management information outside of the MIB-II system branch. Server Administrator SNMP Agent Install Actions If Server Administrator detects the default SNMP configuration during installation, it attempts to modify the SNMP agent configuration to give read-only access to the entire MIB tree for the public community.
To configure your system running Server Administrator to send traps to a management station, edit the SNMP agent configuration file, /etc/snmp/snmpd.conf, and perform the following steps: 1. Add the following line to the file: trapsink IP_address community_name, where IP_address is the IP address of the management station and community_name is the SNMP community name. 2. To enable SNMP configuration changes, restart the SNMP agent by typing: service snmpd restart.
6. To enable SNMP configuration changes, restart the SNMP agent by typing: /etc/init.d/snmpd restart. Changing The SNMP Community Name Configuring the SNMP community name determines which management stations are able to manage your system through SNMP. The SNMP community name used by management applications must match the SNMP community name configured on the system running Server Administrator,, so the management applications can retrieve the management information from Server Administrator.
To configure the SNMP agent: 1. Edit the VMware SNMP configuration file, /etc/vmware/snmp.xml, either manually or run the following vicfg-snmp commands to modify the SNMP configuration settings. This includes the SNMP listening port, community string, and the trap target ipaddress/port, and trap community name and then enable the VMware SNMP service. a) vicfg-snmp.
8. Run the following command to ensure that the SNMP ports are open before sending traps to the management station: esxcfg-firewall -e snmpd. Configuring The SNMP Agent On Systems Running Supported VMware ESXi 4.X And ESXi 5.X Operating Systems Server Administrator supports SNMP traps on VMware ESXi 4.X and ESXi 5.X. If a stand-alone license is only present, SNMP configuration fails on VMware ESXi operating systems. Server Administrator does not support SNMP Get and Set operations on VMWare ESXi 4.
To open the SNMP port on Red Hat Enterprise Linux using one of the previously described methods: 1. At the Red Hat Enterprise Linux command prompt, type setup and press to start the Text Mode Setup Utility.

Server Administrator Logs 6 Server Administrator allows you to view and manage hardware, alert, and command logs. All users can access logs and print reports from either the Server Administrator home page or from its command line interface. Users must be logged in with Administrator privileges to clear logs or must be logged in with Administrator or Power User privileges to e-mail logs to their designated service contact.
• • • Hardware Log Alert Log Command Log Hardware Log On Dell PowerEdge 9G and 11G systems, use the hardware log to look for potential problems with your system's hardware components. the hardware log status indicator changes to critical status ( ) when the log file reaches 100 percent capacity. There are two available hardware logs, depending on your system: the Embedded System Management (ESM) log and the System Event Log (SEL).
the severity and cause of the event and provide other relevant information such as the location of the event and the monitored component's previous state. To access the Alert log, click System, click the Logs tab, and click Alert.
Setting Alert Actions 7 Setting Alert Actions For Systems Running Supported Red Hat Enterprise Linux And SUSE Linux Enterprise Server Operating Systems When you set alert actions for an event, you can specify the action to display an alert on the server. To perform this action, Server Administrator sends a message to /dev/console. If the Server Administrator system is running an X Window System, the messsage is not displayed.
Setting Alert Actions In Microsoft Windows Server 2003 And Windows Server 2008 When specifying alert actions, Visual Basic scripts are not automatically interpreted by the Execute Application feature, although you can run a .cmd, .com, .bat, or .exe file by only specifying the file as the alert action. To resolve this issue, first call the command processor cmd.exe to start your script. For example, the alert action value to execute an application can be set as follows: c:\winnt\system32\cmd.exe /c d:\examp
When the DSM SA Data Manager service is restarted with this change, the Service Control Manager logs the following message to the System log: The DSM SA Data Manager service is marked as an interactive service. Enabling the Interactive Services Detection service allows the DSM SA Data Manager service to execute interactive applications properly for an Alert Action.
