Standards-Based Management; Accessing And Configuring Ilo; Methods To Access Ilo - HP AB500A - Integrated Lights-Out Advanced Technology Brief

available in the more information section at the end of this document. For example, administrators can
automatically power off servers, mount virtual CD images, and power on servers to deploy an OS to
multiple servers. Or administrators can use these tools to browse to an iLO processor and access the
iLO interface. This provides easy access to the iLO management features of HP ProLiant server
systems.

Standards-based management

Technologies for server management continue to evolve and multiple server management
specifications are contending for industry-standard status. To solve the customer's need for
standardization, HP has contributed to the development of several specifications, and is strategically
incorporating the industry-wide initiatives of Systems Management Architecture for Server Hardware
(SMASH) and WS-Management into its management tools, including iLO processors and HP SIM.
With the SMASH Server Management Command Line Protocol (SM CLP), administrators can
interrogate and control systems directly, such as reading the iLO system log to find server status or to
indicate server health. Administrators can also use scripting with command-line protocols to directly
manage a wide range of servers interactively.
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 management
processors.
HP delivered the first implementation of SMASH-based technology with the first-generation iLO v1.70.
As of this writing, administrators can use SM CLP to configure, update, and operate iLO features on
HP ProLiant ML/DL 300 and 500 series servers, ProLiant SL products, and ProLiant BL server blades.
HP is not planning WS-Management support for the first-generation iLO processor. WS-Management
is one of the leading industry initiatives and is supported by iLO 2.
The iLO 2 v1.00 processor supports the draft SM CLP specification, and iLO 2 v1.30 adds
WS-Management. This feature adds a new interface for accessing some of the information for the
iLO 2 processor and sensors described by the Intelligent Management Platform Interface (IPMI)
records. This allows HP SIM to access IPMI sensors through the WS-Management interface. The exact
type and number of sensors depends on the server. Future firmware revisions are expected to
broaden WS-Management support, thereby increasing iLO capabilities.

Accessing and configuring iLO

The iLO processor is designed to be flexible and reliable. Therefore, HP incorporated a variety of
tools, such as a web browser or scripting tools, that administrators can use to access the iLO
processor. Administrators also have multiple options for configuring the iLO and iLO 2 processors.

Methods to access iLO

Because each data center or remote site may have different access requirements, HP designed the iLO
processor with multiple options for accessibility: web-based or text-based. Administrators have web-
based access to the iLO management console through a standard browser such as Microsoft Internet
Explorer or Mozilla Firefox. 10 The iLO 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.
