Remote Access Management
Dell OpenManage™ IT Assistant User's Guide
The Dell OpenManage Remote Assistant Card II (DRAC II), Dell Remote Access
Card III (DRAC III), Dell Remote Access Card III/XT (DRAC III/XT), Embedded Remote Access (ERA),
Embedded Remote Access
Option (ERA/O), and Embedded Remote Access/MC (ERA/MC) are systems management hardware and software solutions designed
to provide remote management capabilities for server systems.
Collectively, these solutions are known as remote access controllers (RACs).
RACs are always installed in a host server system, or in the case of ERA/MC, in
a host modular system.
During normal system operation, a RAC provides management capability for its
host. A RAC communicates with the host's Embedded
Server Management (ESM)
system, which monitors critical server components. The RAC can send notifications to
preset destinations on receipt of alerts generated by ESM. ESM generates alerts when
component conditions on the host exceed threshold values. However, you cannot set alert thresholds for
component conditions through the RAC; you must set the thresholds through IT
Assistant.
If the host becomes inoperable, a RAC provides remote access, which is a communications path to the host
using resources on the RAC (network interface controller [NIC], modem, serial
port) rather than the host system's NIC.
 |
NOTE: Not all RACs have all three remote access
resources (ports) described above (NIC, modem, serial port). See your RAC
documentation for the remote access ports available on your RAC. |
Remote access allows you to get the
system up and running as quickly as possible. While the system is down, a RAC provides alert notification
and allows you to remotely restart the system. In addition, some RACs log the
probable cause of system crashes and enable you to view the most recent crash
screen.
IT Assistant discovers, monitors, and allows you to configure RACs installed in
host servers. IT Assistant also enables you to connect to a RAC's remote access
port(s) and run the RAC's remote access interface, which is the program
you use to access the RAC's server management
capabilities.
For DRAC II, the remote access interface is the Dell OpenManage Remote
Assistant program or the DRAC II Web Console program. For DRAC III, DRAC III/XT,
ERA, ERA/O,
and ERA/MC, the remote access interface program
is embedded in the RAC's firmware along with a Web server. This arrangement enables you to use
IT Assistant or just a Web browser from any system on the network to connect to the RAC and
run the remote access interface.
 |
NOTE: RACs communicate using Simple Network Management Protocol
(SNMP) only. |
To add connection information for a RAC to the remote access address
book, perform the following
steps:
- On the IT Assistant
navigation tree, expand the Management branch and click Remote Access
Address Book.
- In the remote access address book window, click Add.
- In the Add Entry dialog box, enter the required connection information in the
fields provided.
See "Add Entry/Edit Entry" for information
on valid values for each field.
- Click Save.
The new entry appears in the system list.
To edit connection information for remote access hardware, perform the following
steps:
- On the IT Assistant
navigation tree, expand the Management branch and click Remote Access
Address Book.
- In the remote access address book window, click
a system in the system list.
- Click Edit.
- In the Edit Entry dialog box, change the information in the connection
information fields as necessary.
See "Add Entry/Edit Entry" for information
on valid values for each field.
- Click Save.
To import connection information for remote access hardware, perform the following
steps:
- On the IT Assistant
navigation tree, expand the Management branch and click Remote Access
Address Book.
- Click Import DRAC II Address Book.
IT Assistant imports all the entries in the DRAC II address book server (installed on
the management station) into its remote access address book. IT
Assistant considers the data in the DRAC II address book more up-to-date and overwrites
any existing information in its remote access address book. If
there is no DRAC II address book server running on the management station, then no
entries are imported.
 |
NOTE: Communication with DRAC II,
ERA, and
ERA/O is supported through SNMP only. |
 |
NOTE: You can connect to only one RAC at a time. |
The following are the prerequisites for connecting to RACs using IT Assistant:
- For DRAC III modem connections, the Remote Access Service (RAS) must be installed on the management station, and the management station must have a working modem. See
your Dell Remote Access Controller (RAC) Installation and Setup Guide for information on installing RAS and configuring
the modem.
You must also install the DRAC III management station components on the management station. These components comprise the DellRasDll libraries
required for IT Assistant to launch the remote access interfaces using a modem
connection. You can install Dell RAC management station components from the Dell
OpenManage Systems Management CD.
- For a DRAC II, the DRAC II address book server must be installed on the management station.
- For the managed system, a DRAC II or DRAC III must be installed.
The following subsections describe three methods that you can use to connect to a
RAC through IT Assistant.
Using the Remote Access Hardware Command
 |
NOTE: This method only
works if you are connecting to a DRAC II or DRAC III. |
- On the IT Assistant
navigation tree, expand the Configuration branch and click Remote Access Hardware.
- In the remote access hardware window, click a
system in the system list.
- Click Remote Connect.
A new window opens and loads the management interface for the RAC installed on the currently selected system. If the
RAC is a DRAC II, you
must have Dell OpenManage Remote Assistant installed at the location specified in the Remote Access application definition.
Using the Status Tab
- In the IT Assistant navigation tree,
expand the Views branch and click Systems.
- In the systems window, click a system in the system tree, and then click the Status tab.
- In the status tree, click the remote access
hardware entry.
If the currently selected system is equipped with RAC, DRAC II, DRAC
III, or ERA appears in the status tree. If none of these entries appear, the currently
selected system is not equipped with a RAC to
which IT Assistant can connect.
- Click Remote Connect.
A new window opens and loads the remote access interface for the RAC installed on the currently selected system. If the
RAC is a DRAC II, you
must have Dell OpenManage Remote Assistant installed at the location specified in the Remote Access application definition.
Using the Remote Access Address Book.
- In the IT Assistant
navigation tree, expand the Management branch and click Remote Access Address Book.
- In the remote
access address book window, click a system in the system list.
- Click Connect.
A new window opens and loads the remote access interface for the RAC installed on the currently selected system. If the
RAC is a DRAC II, you
must have Dell OpenManage Remote Assistant installed at the location specified in the Remote Access application definition.
- Clicking the "X" on the upper right corner of the window created
by a DRAC III interface launch using the modem connection does not
close the session or log the DRAC III user out. IT Assistant caches the current
session. To clear the cache, log out of the DRAC III browser-based interface
by clicking File® Log Out.
- When you create a DRAC II user in IT Assistant, ensure that the user name
and password are lowercase. You cannot log in to the DRAC II Web console if the
user name or password contain uppercase letters.
