Integrated Lights-Out 3 technology

Standards-based management

Technologies for server management continue to evolve, and multiple server management specifications

are contending for industry-standard status. We have contributed to the development of several

specifications and have strategically incorporated them into our management tools.

iLO 3 supports the Systems Management Architecture for Server Hardware (SMASH) initiative. With the

SMASH Server Management Command Line Protocol (SM CLP), you can interrogate and control systems

directly. This lets you perform tasks like reading the iLO 3 system log to find server status or to monitor

server health. You can also use scripting with command-line protocols to manage a wide range of servers

interactively. You can use SM CLP to configure, update, and operate iLO 3 features on HP ProLiant ML/DL

300 and 500 series servers, ProLiant SL products, and ProLiant BL server blades.

iLO 3 also supports IPMI over LAN/DCMI to perform simple monitoring and control in scale-out

environments. We add an additional interface for accessing IPMI information from iLO 3 and IPMI

sensors. Our implementation allows HP SIM to access IPMI sensors through the WS-Management

interface. The exact type and number of sensors depends on the server. IPMI over LAN/DCMI performs

monitoring and control operations that let you determine whether a server is offline. It also provides the

ability to power on and power off servers remotely.

The future iLO 3 v1.15 firmware will support the Web Services (WS) Management initiative. WS-

Management will provide a common method for systems to access and exchange management

information across the IT infrastructure. The specification defines a Simple Object Access Protocol (SOAP)-

based protocol, supporting more than a get/set collection of simple variables. WS-Management also

defines a mapping of the Distributed Management Task Force (DMTF) Common Information Model (CIM).

WS-Management is emerging as the preferred programmatic interface for system management.

Programmatic protocols, such as WS-Management, are machine-oriented and enable applications to

manage the systems. For example, HP SIM uses WS-Management to interact with iLO 3 processors. Future

firmware revisions will continue to broaden WS-Management support.

Simple Network Time Protocol

Computers use the Simple Network Time Protocol (SNTP) to synchronize internal system clocks over data

networks. Internal system clocks will gain or lose time, relative to each other, over time, even when initially

synchronized. The problem becomes more substantial in a distributed system when the computers must

remain synchronized. iLO 3 can synchronize its clock with an SNTP server if configured to do so.

Accessing and configuring iLO 3

Methods to access iLO 3

Because each data center or remote site may have different access requirements, you can access iLO 3

using web-based or text-based tools. You have web-based access to the iLO 3 management console

through a standard browser such as Microsoft Internet Explorer or Mozilla Firefox. Refer to the user guide

at http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02250422/c02250422.pdf for

supported browser versions. The iLO 3 web interface groups similar tasks together and organizes them

under high-level tabs such as System Status, Remote Console, Virtual Media, Power Management, and

Administration.

You can access iLO 3 using SSH and the virtual serial port if you want to use text-based controls. See the

section “Text-based remote console (Virtual Serial Port).” The text-based interface lets you use SMASH SM

CLP to configure or update iLO 3 and execute iLO 3 processes.

Configuring iLO 3

You can configure individual iLO 3 processors in any of the following ways:
