Overview of the ILOM on the Sun Blade X6275 Server Module

The Integrated Lights Out Manager (ILOM) is system management firmware that allows you to manage your Sun server when the host system is powered down. This is possible because the ILOM runs on a separate Service Processor (SP) that is powered by the host system’s standby power.

The following interfaces provide network access to the ILOM: command-line interface (CLI), web interface, SNMP, and IPMI.

The ILOM also supports remote access to the host’s system console through a network remote keyboard video and mouse (RKVM). The host’s I/O to optical and floppy drives can be redirected to real and virtual drives on the network. This allows a remote user to perform most maintenance operations, including installing an operating system.

The server module’s ILOM can also be accessed through the chassis ILOM, which is called the Chassis Management Module (CMM). Refer to the Chassis ILOM documentation for more information.

ILOM Features Not Supported

Not all common ILOM features are supported on every platform. On the Sun Blade X6275 Server Module,the following features are not supported:

• Intrusion Detection - Intrusion detection is applicable for rack-mounted systems but not for blade server modules.

All other features are supported. However, some features have been enhanced, and others have been added. These are described in Platform-Specific ILOM Features.

Platform-Specific ILOM Features

The Sun Blade X6275 server module has some unique features, and the ILOM has been modified to support them.

The following sections and chapters describe the features that are modified or added to the ILOM for the Sun Blade X6275 server module:

• Features to support dual nodes - See Dual-Node Identification.
• Web interface - See Web Interface.
• Fault management - See Clearing Server Faults.
• Power management - See Power Management Metrics.
• Serial port sharing - See Switching Serial Port Output Between SP and Host Console.
• CMM policy for cooling door - See Enabling and Disabling the Sun Cooling Door.
• Preboot menu - See Chapter 2.
• Sensors and indicators -- See Chapter 4.

Dual-Node Identification

A single Sun Blade X6275 server module contains two complete systems, each referred to as a node. Each node has its own SP running its own ILOM.

To handle this, the CMM ILOM displays slot addresses as if there are two separate server modules.

• Node 0 is addressed by the actual slot number.
• Node 1 is addressed by the slot number plus 12. For example, for a server module in slot 6:
• Node 0 is addressed by the actual slot number, 6.
• Node 1 is addressed by slot 18 (the actual slot number plus 12).

This convention is reflected in the following CMM ILOM features:

• The /SYS/SLOTID target is different for the two blade ILOMs.
• The chassis’ CMM ILOM provides separate targets for each blade. For example, if the blade is in slot 6, then the CMM ILOM provides /CH/BL6 and /CH/BL18.
• The CMM ILOM web interface provides separate management displays for the two blade ILOMs, using the two slot IDs. For more information, see Chapter 2.

Web Interface

You can access the web interface for either ILOM by entering the Service Processor’s network address in a browser address bar. Alternately, you can use the CMM network address to access the CMM ILOM, which also provides access to individual blade ILOM web interfaces.

FIGURE 1-1 shows the web interface of a CMM ILOM provisioned with Sun Blade X6275 server modules.

• Slots 0 through 11 each show node 0 of their respective server modules.
• Slots 12 through 23 show node 1 of the server modules in slots 0 through 11.

To access the web interface for an individual server module ILOM, click on the server module name in the left-hand frame, or click on the graphic representing the server module in the right-hand frame. In the case of a Sun Blade X6275 server module, click on the upper half of the graphic to access node 0, and click on the lower half of the graphic to access node 1.

Clearing Server Faults

The Sun Blade X6275 server module handles faults slightly differently from the common ILOM. The details are provided in the Sun Blade X6275 Server Module Diagnostics Guide.

Power Management Metrics

This section describes the differences between power management metrics in the common ILOM and in the Sun Blade X6275 server module ILOM.

Power Management Metrics in the Common ILOM

The power management function in ILOM 2.0 enables you to monitor power consumption metrics from the command-line interface (CLI) or web interface. The following power management metrics are common to all Sun servers:

• Available power - The available power metric shown in ILOM for a server module represents the maximum amount of power guaranteed to be available to the server module by the system chassis.
• Actual power - The actual power metric shown in ILOM for a server module represents the amount of power consumed by the server.
• Permitted power - The permitted power metric shown in ILOM for a server module represents the maximum power the server guarantees it will consume at any instant.

For examples of these common power management metrics provided in ILOM 2.0, see the web interface example shown in FIGURE 1-2 Power Management Metrics - ILOM Web Interface or the command-line output shown in Step 2 of the To Monitor Advanced Power Metrics From the CLI.

For additional information about the common power management metrics provided for all Sun servers, see the Addendum to the Sun Integrated Lights Out Manager 2.0 User’s Guide or the Sun Integrated Lights Out Manager 2.0 User’s Guide.

Specific Power Consumption Metrics for the Sun Blade X6275 Server Module

In addition to the common power consumption metrics provided in ILOM 2.0 for all Sun servers, the power management function in ILOM 2.0 provides the following advanced power consumption metrics for the Sun Blade X6275 Server Module.

• Power budget - The power budget metric shown in ILOM identifies the maximum power value that the server guarantees it will consume at any instant.
• Power policy - The power policy metric shown in ILOM enables you to determine whether permission was granted by the system chassis to power on the server host. This decision is granted by the system chassis after comparing the amount of power available on the chassis to the amount of power currently being consumed by all components (server modules, NEMs, fans, and so forth) in the system chassis.

For information about how to view these advanced power consumption metrics in ILOM 2.0, see these topics:

• To Monitor Advanced Power Metrics From the Web Interface
• To Monitor Advanced Power Metrics From the CLI

1. Log in to the ILOM web interface.

2. Select System Monitoring --> Power Management.

The common power consumption metrics and advanced power consumption metrics for the Sun Blade X6275 Server Module appear.

FIGURE 1-2 Power Management Metrics - ILOM Web Interface

1. Log in to the ILOM CLI.

2. To display the actual power, permitted power, and available power, use the show command. For example:

-> show /SP/powermgmt
/SP/powermgmt
Targets:
advanced

Properties:
actual_power = 88.2
permitted power = 366
available power = 366
Commands:
cd
show

3. To display the advanced power metric properties for power budget and power policy use the show /SP/powermgmt/advanced/n command:

where:

n = 1 for power budget

n = 2 for power policy

For example:

-> show /SP/powermgmt/advanced/1
/SP/powermgmt/advanced/1
 Targets:
Properties:
name = Power Budget
unit = Watts
value = 361
Commands:
cd
show

-> show /SP/powermgmt/advanced/2
/SP/powermgmt/advanced/2
 Targets:
Properties:
name = Power policy permits power-on?
unit = Boolean Value (1 = Yes, 0 = NO)
value = 1
Commands:
cd
show

Switching Serial Port Output Between SP and Host Console

You can switch the serial port output of the server module between the SP console and the host console. By default, the SP console is connected to the system serial port. This feature allows you to view non-ASCII character traffic from the host console.

You can switch serial port output using either the web interface or the CLI. For instructions, see the following sections:

• To Switch Serial Port Output Using the Web Interface
• To Switch Serial Port Output Using the CLI

Caution - Set up the network on the SP before attempting to switch the serial port owner to the host server. If a network is not set up, and you switch the serial port owner to the host server, you will be unable to connect via the CLI interface or web interface to change the serial port owner back to the SP. To change the serial port owner back to the SP, you must perform the procedures in Restoring ILOM Access to the Serial Console.
