Server management through IPMI version 2.0 compliant applications
Server management through the IPMI is a standardized method for controlling and monitoring the
server. iLO 2 provides server management based on the IPMI version 2.0 specification.
The IPMI specification defines a standardized interface for platform management. The IPMI
specification defines the following types of platform management:
•
Monitoring of system information, such as fans, temperatures, and power supplies
•
Recovery capabilities, such as system resets and power on/off operations
•
Logging capabilities, for abnormal events such as over temperature readings or fan failures
•
Inventory capabilities, such as identifying failed hardware components
IPMI communications are dependent on the BMC and the SMS. The BMC manages the interface
between the SMS and the platform management hardware. iLO 2 emulates the BMC functionality
and the SMS functionality can be provided by various industry-standard tools. For additional
information, see the IPMI specification on the Intel website at
.
The iLO 2 firmware 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 include:
•
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 at
.
•
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 at
.
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 uses 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 might detrimentally
affect 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.
