Chapter 3. System Operation

This chapter describes how to operate your SGI Origin 300 system with NUMAlink module. Specifically, it explains how to perform the following procedures:

Connecting a System Console to Your System

The system console enables you to perform the following activities:

  • Monitor your system by reading the status and error message information that the L1 and L2 controllers generate.

  • Enter L1 and L2 controller commands to monitor or change particular system functions. You can, for example, monitor the speed of fans for a particular module.

  • Power on or power off individual modules or all modules (except for the storage modules) in your system.

  • If you connect a console that contains SGIconsole software, you can perform the functions listed above and have boundary scan capabilities. Boundary scan capabilities enable an SGI system support engineer (SSE) to test the functionality of your system.

To attach a system console that runs the SGIconsole software to your system, connect the system console to the L2 controller Ethernet port connector as shown in Figure 3-1.

Figure 3-1. Connecting the System Console to the L2 Controller Ethernet Port

Connecting the System Console to the L2 Controller Ethernet Port

Connecting a Myrinet-2000 Switch to Your System (Clustered Systems Only)

SGI ships your system with all Myrinet hardware installed in the rack: the Myrinet PCI cards are installed in the Origin 300 base modules (refer to Figure 3-2), and the Myrinet-2000 switch is installed in rack 001 or 002, depending on your configuration. The system does not ship with the fiber cables attached to the hardware.

To attach the fiber cables, connect one end of a fiber cable to a Myrinet PCI card in an Origin 300 base module. Connect the other end of the fiber cable to a fiber port of one of the port line cards in the Myrinet-2000 switch. It does not matter which fiber port you use.

In addition to attaching the fiber cables, ensure that the Myrinet-2000 switch is connected to a power distribution unit (PDU) or power strip.

For software setup, refer to the release notes (relnotes) that are provided with the Myrinet software. After you install the software, use the relnotes and grelnotes (graphics viewer for online release notes) to configure and validate the Myrinet-2000 switch.

Powering Your System On and Off

The following sections describe how to power on and power off individual modules or your entire SGI Origin 300 system.

You can power on and power off individual modules and the entire system via the system console.


Note: The following information applies to the Origin 300 base modules, the NUMAlink module, and PCI expansion modules. You must manually power on a TP900 storage module by placing the power switch(es) in the 1 position. Refer to Figure 3-20.

Figure 3-20. TP900 Power Switch (1 Position)

TP900 Power Switch (1 Position)

Powering On

This section describes how to perform the following procedures:

  • Preparing to power on

  • Powering on at the system console

  • Powering on with power buttons

Preparing to Power On


Warning: The rackmount system operates on 200-240 Vac. Use extreme caution when you work near this voltage.

To prepare to power on the system, perform the following tasks:

  • Confirm that the power cables between the following components are secure:

    • Between the power distribution unit (PDU) and the external power receptacle.

    • Between the PDU and the following components: Origin 300 base module(s), AC-powered NUMAlink module, USB hub, TP900 storage module(s), power bay, power strip, L2 controller power supply, and Myrinet-2000 switch.

    • Between the power bay and the following modules: DC-powered NUMAlink module, PCI expansion module(s), and L2 controller module (refer to Figure 3-21).


      Note: When the system contains an AC-powered NUMAlink module, the L2 controller does not receive power from a power bay; instead, it receives power from a power supply. This power supply receives AC voltage from a PDU or power strip and converts the voltage to 48 Vdc, which is the input voltage that the L2 controller requires.


    Figure 3-21 shows the PDU and power bay connections to the components within a system that contains a DC-powered NUMAlink module.

  • Confirm that the cables between the L2 controller and the following components are secure:

    Figure 3-22 shows how the system components connect to the L2 controller.

  • Ensure that the power switch on each DC-powered NUMAlink and PCI expansion module that you want to power on is set to the On (1) position. The power switch is located in the upper-left corner of the module (refer to Figure 3-23). This switch enables the L1 controllers of the NUMAlink module and PCI expansion modules to power on after you turn on the circuit breaker of the PDU.


    Note: The Origin 300 base and AC-powered NUMAlink modules do not have a power switch; when the PDU circuit breaker is on, their L1 controllers are on.

Powering On at the System Console

Power on the system as follows:

  1. If the monitors and other peripherals are equipped with voltage select switches, verify that they are set for the appropriate AC voltage and plug them in. Note that they are normally plugged into sources outside the rack system.

  2. Turn on the circuit breaker switch of the PDU as shown in Figure 3-24.

    Figure 3-24. PDU Circuit Breaker Switch

    PDU Circuit Breaker Switch

  3. Verify that all of the L1 controllers display “L1 running.” If any L1 controllers are not running, contact your SGI system support engineer (SSE).

  4. At the system console, access the L2 controller by entering the following command:

    $> /stand/sysco/bin/12term
    

  5. From the L2 prompt, display the system configuration by entering the following command:

    L2> cfg 
    

    This command lists the modules that the L2 controller detects in the system and their system controller addresses. If a module that you want to power on does not appear in the list, it will not power on. Ensure that the module's L1 controller is running and that it is cabled properly.

  6. From the L2 prompt (L2>), power on an individual module by entering the following command. (If you want to power on the entire system, proceed to Step 7.)

    L2> r <rack#> s <slot#> pwr u 
    

    For example, to power on an Origin 300 base module in rack 1, slot 18, enter the following command:

    L2> r 1 s 18 pwr u 
    

    The slot number is the unit number of the module within the rack. For more information about unit numbers, refer to Chapter 1 of this document.

    If you want to power on several selected modules of a rack at the same time, you must enter the rack number followed by the slot numbers of the modules that you want to power on. For example, to power on the modules in slots 18, 20, and 22, enter the following command:

    L2> r 1 s 18,20,22 pwr u
    

  7. If you want to power on the entire system, enter the following command:

    L2> pwr u
    

    (The default setting for the pwr u command is all racks and slots.)

  8. When the L2 prompt appears, you will not see the output that is produced during the power-on procedure unless you redirect the keyboard input from the L2 controller to the normal console by typing control d.

    L2> ctrl d
    

  9. When the power-on procedure completes, the System Maintenance Menu appears on the system console. Select option 1 “Start System” to boot the IRIX operating system.

Powering On with Power Buttons

If your system does not have a system console, you can power on your system manually by using power buttons. Each module that has an L1 controller has a power button with an LED; this button is located on the front of the module (refer to Figure 3-25). The TP900 storage module power switch(es) are located at the rear of the module (refer again to Figure 3-20).

Figure 3-25. Front View of Origin 300 Base Module

Front View of Origin 300 Base Module

To power off your system using the system console, follow these steps:

  1. Shut down the IRIX operating system by entering the following command:

    # init 0
    

  2. To access the L2 prompt, direct the keyboard input to the L2 controller by entering control t.

    $> ctrl t
    

  3. From the L2 prompt (L2>), power off an individual module by entering the following command. (If you want to power off the entire system, proceed to Step 4.)

    L2> r <rack#> s <slot#> pwr d 
    

    For example, to power off an Origin 300 base module in rack 1, slot 18, enter the following command:

    L2> r 1 s 18 pwr d 
    

    The slot number is the unit number of the module within the rack. For more information about unit numbers, refer to Chapter 1 of this document.

    If you want to power off several selected modules from the rack at the same time, enter the rack number followed by the slot numbers of the modules that you want to power off. For example, to power off the modules in slots 18, 20, and 22, enter the following command:

    L2> r 1 s 18,20,22 pwr d
    

  4. If you want to power off all of the modules within the rack, enter the following command:

    L2> pwr d 
    (The default setting for the pwr d command is all racks and slots.)
    

    “Powered Down” appears on the L1 display when the module is powered off. The L1 controller is still powered on.

  5. To power down an L1 controller of a DC-powered NUMAlink or PCI expansion module, set the power switch to the Off position. The power switch of the NUMAlink or PCI expansion module is located in the upper-left corner of the rear of the module.


    Note: The Origin 300 base and AC-powered NUMAlink modules do not have a power switch. To power down their L1 controllers, unplug the modules from the PDU.


Powering Off with Power Buttons

To power off your system manually, follow these steps:

  1. Shut down the IRIX operating system by entering the following command:

    # init 0
    

  2. Press the power buttons that are located on the front of the modules that you want to power off. You may power off the modules in any order.

  3. To power off an L1 controller of a DC-powered NUMAlink or PCI expansion module, set the power switch to the Off position. The power switch of the NUMAlink or PCI expansion module is located in the upper-left corner at the rear of the module.


    Note: The Origin 300 base and AC-powered NUMAlink modules do not have a power switch. To power off their L1 controllers, unplug the modules from the PDU.


Monitoring Your System

You can monitor your SGI Origin 300 system from the following sources:

  • You can view individual module (base, NUMAlink, and PCI expansion) status and error messages via the module's L1 controller display. For example, you can determine whether the fans of a particular module are operating properly.

  • The system console enables you to view the status and error messages that are generated by both the L1 and L2 controllers. Refer to Appendix C, “System Controller Commands” for L1 and L2 commands.

  • You can monitor the status of the TP900 storage modules by viewing the LEDs on the front and the rear of the storage modules.

  • You can use the Embedded Support Partner (ESP) system, which is discussed in the next section.

Using Embedded Support Partner (ESP)

Embedded Support Partner (ESP) automatically detects system conditions that indicate potential future problems and then notifies the appropriate personnel. This enables you and SGI system support engineers (SSEs) to proactively support systems and resolve issues before they develop into actual failures.

ESP enables users to monitor one or more systems at a site from a local or remote connection. ESP can perform the following functions:

  • Monitor the system configuration, events, performance, and availability.

  • Notify SSEs when specific events occur.

  • Generate reports.

ESP also supports:

  • Remote support and on-site troubleshooting.

  • System group management, which enables you to manage an entire group of systems from a single system.

For more information about ESP, refer to Chapter 5, “Troubleshooting.” For information about configuring ESP, refer to the Embedded Support Partner User Guide.
