Operational overview 12
iLO 2 provides the KCS interface, or open interface, for SMS communications. The KCS interface provides
a set of I/O mapped communications registers. The default system base address for the I/O mapped
SMS Interface is 0xCA2 and is byte aligned at this system address.
The KCS interface is accessible to SMS software that is running on the local system. Examples of
compatible SMS software applications are as follows:
•
IPMI version 2.0 Command Test Tool is a low-level MS-DOS command line tool that enables hex-
formatted IPMI commands to be sent to an IPMI BMC that implements the KCS interface. You can
locate this tool on the Intel® website (
http://www.intel.com/design/servers/ipmi/tools.htm
).
•
IPMItool is a utility for managing and configuring devices that support the IPMI version 1.5 and
version 2.0 specifications and can be used in a Linux environment. You can locate this tool on the
IPMItool website (
http://ipmitool.sourceforge.net/index.html
).
IPMI functionality provided by iLO 2
When emulating a BMC for the IPMI interface, iLO 2 supports all mandatory commands listed in the IPMI
version 2.0 specification. See the IPMI version 2.0 specification for a listing of these commands. Also, the
SMS should use the methods described in the specification for determining which IPMI features are
enabled or disabled in the BMC (for example, using the Get Device ID command).
If the server operating system is running and the health driver is enabled, any IPMI traffic through the KCS
interface can affect the performance of the health driver and overall health performance of the system. Do
not issue any IPMI commands through the KCS interface that could have a detrimental affect on the
monitoring performed by the health driver. These commands include any commands that sets or changes
IPMI parameters, such as
Set Watchdog Timer
and
Set BMC Global Enabled
. Any IPMI
command that simply returns data is safe to use, such as
Get Device ID
and
Get Sensor Reading
.
WS-Management compatibility overview
The iLO 2 firmware implementation of WS-Management is in accordance with the specification, DTMF
Web Services for Management
1.0.0a.
Authentication
•
iLO 2 uses basic authentication over SSL, compliant with profile:
wsman:secprofile/https/basic
•
Authenticated users are authorized to execute WS-Management commands in accordance with
designated privileges in their local or directory accounts.
•
To enable basic authentication on Microsoft® Windows Vista™, at the command prompt, enter
gpedit.msc
to launch the Group Policy Object Editor. Select
Computer Configuration>
Administrative Templates> Windows Components> Windows Remote Management (WinRM)>
WinRM Client.
Set Allow Basic authentication to
Enabled.
Compatibility
•
WS-Management in iLO 2 are compatible with the Windows Vista™ WinRM utility, Microsoft®
Operations Manager 3, and the Management Pack provided by HP.
•
The full set of WS-Management commands is available on iLO 2 servers that support embedded
system health. A greatly reduced subset of these commands is available on servers without
embedded systems health support.
Commands are available for remote invocation of the following devices:
•
Server power
