C H A P T E R 2

Use the instructions in this chapter to install the server module into the chassis.

Handling the Server Module

Electronic equipment is susceptible to damage by static electricity. Use a grounded antistatic wriststrap, footstrap, or equivalent safety equipment to prevent electrostatic damage (ESD) when you install the server module.

Caution - To protect electronic components from electrostatic damage, which can permanently disable the system or require repair by Sun service technicians, place components on an antistatic surface, such as an antistatic discharge mat, an antistatic bag, or a disposable antistatic mat. Wear an antistatic grounding strap connected to a metal surface on the chassis when you work on system components.

Installing the Server Module into the Chassis

To Insert the Server Module

1. Ensure that you have the MAC address and serial number.

This information is on the customer information sheet attached to the shipping container. The serial number is also on the front of the server module.

2. Ensure that the modular system chassis is powered on.

Refer to You can also use a pointed object or stylus to press and release the recessed Power button on the server front panel. and to the documentation that came with your Sun Blade modular system.

3. Locate the desired slot in the chassis.

4. Remove the filler panel from the target slot, if applicable.

5. (Optional) Attach a serial cable from the terminal server to the virtual console connector on the dongle cable.

If you plan to use a dongle cable to connect directly to the server module, you must connect the terminal server to the dongle cable before you insert the server module so that you can see the boot messages for the ILOM firmware. Refer to the sections Managing the Server Module With ILOM and Connecting and Configuring the Server Module for more information.

a. Attach the dongle cable to the server module.

Refer to Attaching a Serial Console to the Server Module.

b. Attach a serial cable from the terminal server to the virtual console connector on the dongle cable.

Connecting to the Server Module

This section describes how to connect to the server module SP using one of the methods listed below and described in the corresponding sections:

Connect to the CMM SP Using Ethernet Port NET MGT 0. Use the CMM service processor proxy and the command line interface to navigate to the Sun Blade T6340 server module SP ILOM firmware. You can also use the CMM SP web interface to control the server module (Items 1 through 3 in FIGURE 2-2). This method is described in this getting started guide. See Connecting Through the Chassis CMM Ethernet Port.

Connect to the CMM serial connector (SER MGT). Use the CMM SP proxy to navigate to the server module SP ILOM firmware. This method supports CLI access only (Item 6 in FIGURE 2-2). See Connecting to the Server Module SP Through the Chassis CMM Serial Connector.

Use a dongle cable to connect directly to the server module SP with an RJ45 serial connection. This method supports CLI access only (Items 7 and 9 in FIGURE 2-2). Dongle cables are intended for setup, testing, or service purposes and should be removed when not in use. See Connecting to the Server Module SP Using a Dongle Cable.

Use a dongle cable to connect directly to the server module host with a local keyboard, video, and mouse (local KVM). (Items 8 and 9). See Connecting to the Server Module With a Local Graphics Monitor or Local KVMS.

Connect to the server module SP using the Ethernet (DHCP or static). This method supports a CLI, or a web interface. The web interface can also control the server module host using a remote keyboard, video and mouse (remote KVM). (Items 1 through 3 in FIGURE 2-2).

Connecting Through the Chassis CMM Ethernet Port

The Ethernet port on the modular system chassis provides the most robust method of connecting to the CMM and the server module SP. This connection supports both the CLI and the web interface.

You can connect to the CMM through the RJ-45 NET MGT 0 Ethernet port.

Before you can use the Ethernet connection, you must know the IP addresses for the CMM and server module SP to which you want to connect. To configure the IP address on the Sun Blade T6340 server module, refer to Configuring and Viewing the IP Address for a Server Module SP.

Configuring and Viewing the IP Address for a Server Module SP

You can configure and view the network IP address for the server module SP in two ways:

Connect to the CMM in the Sun Blade modular system chassis.

Refer to Configuring and Viewing the IP Address for a Server Module SP Through the CMM.

Connect directly to the server module SP through the UCP.

Refer to Configuring and Viewing the IP Address for a Server Module SP Through the UCP.

Configuring and Viewing the IP Address for a Server Module SP Through the CMM

You can attach to the CMM on the modular system chassis through a serial port or an Ethernet port:

CMM serial port - You can attach a terminal device. Refer to Connecting to the Server Module SP Through the Chassis CMM Serial Connector.

CMM Ethernet port - You can connect to your management network. Refer to Connecting Through the Chassis CMM Ethernet Port.

After attaching to the CMM by using one of these ports, you can log in to the CMM ILOM software to configure and view your server module IP address, whether the IP address is assigned by DHCP or a static IP address.

To View or Configure the IP Address for the Server Module SP When Assigned by DHCP -- Through the CMM

1. Verify that your DHCP server is configured to accept new media access control (MAC) addresses.

2. Attach to the CMM using the CMM serial or Ethernet port.

3. Find the IP address that DHCP has assigned to the server module SP.

A valid IP address may already have been assigned to the server module SP by your DHCP server. To view the IP address that has been assigned, type:

-> show /CH/BLn/SP/network ipaddress

Where n is an integer representing the slot where the target server module is installed. The CMM ILOM software displays the IP address currently assigned to the server module SP.

If the assigned IP address is not valid, you should provide the MAC address for the server module SP to your DHCP system administrator. In that case, proceed to Step 4.

4. Obtain the MAC address for the server module SP.

MAC addresses are 12-digit hexadecimal strings in the format xx:xx:xx:xx:xx:xx where x represents a single hexadecimal letter (0-9, A-F, a-f).

The Customer Information document shipped with your server module lists the MAC address, or you can find it using this procedure:

a. Log in to the CMM ILOM software and type:

-> show /CH/BLn/SP/network macaddress

Where n is an integer representing the slot where the target server module is installed. The CMM ILOM software displays the current MAC address.

b. Write down the MAC address and use it to configure your DHCP server.

5. View the IP address that DHCP has assigned to the server module SP.

After a valid IP address has been assigned to the server module, view the IP address, as described in Step 3.

To View or Configure the IP Address for the Server Module SP Using Static IP Addresses -- Through the CMM

1. Attach to the CMM using the CMM serial or Ethernet port.

2. (Optional) View the IP address.

To see all the IP address-related information, type:

-> show /CH/BLn/SP/network

To see only the IP address, type:

-> show /CH/BLn/SP/network ipaddress

3. Navigate to /CH/BLn/SP/network by typing the following command:

-> cd /CH/BLn/SP/network

4. Type one of the following commands:

To configure a static Ethernet configuration:

-> set pendingipdiscovery=static 
-> set pendingipaddress=xxx.xxx.xx.xx 
-> set pendingipnetmask=yyy.yyy.yyy.y 
-> set pendingipgateway=zzz.zzz.zz.zzz 
-> set commitpending=true

Where xxx.xxx.xx.xx, yyy.yyy.yyy.y and zzz.zzz.zz.zzz are the IP address, netmask, and gateway for your ILOM and network configuration. To determine these addresses, contact your system administrator.

To revert to a dynamic Ethernet configuration:

-> set pendingipdiscovery=dhcp 
-> set commitpending=true

The following display shows a typical session where the user looks at static settings, configures them to be dynamic, then looks at the new settings.

Configuring and Viewing the IP Address for a Server Module SP Through the UCP

You can connect to the server module SP by one of these methods:

Through the front-panel universal connector port (UCP) using a dongle cable.

Through the SP Ethernet port. You must already know the IP address to use this method, so it is not useful for configuration.

To View or Configure the IP Address for the Server Module SP When Assigned by DHCP -- Through the UCP

1. Verify that your DHCP server is configured to accept new media access control (MAC) addresses.

2. Connect to the server module SP through the front-panel UCP using a dongle cable.

Refer to Connecting to the Server Module SP Using a Dongle Cable.

3. Find the IP address that DHCP has assigned to the server module SP.

A valid IP address may already have been assigned to the server module SP by your DHCP server. To view the IP address that has been assigned, type:

-> show /SP/network ipaddress

The ILOM software displays the IP address currently assigned to the server module SP.

If the assigned IP address is not valid, you should provide the MAC address for the server module SP to your DHCP system administrator. In that case, proceed to Step 4.

4. Obtain the MAC address for the server module SP.

MAC addresses are 12-digit hexadecimal strings in the format xx:xx:xx:xx:xx:xx where x represents a single hexadecimal letter (0-9, A-F, a-f).

The Customer Information document shipped with your server module lists the MAC address, or you can find it using this procedure:

a. Type this command:

-> show /SP/network macaddress

The ILOM software displays the current MAC address.

b. Write down the MAC address and use it to configure your DHCP server.

5. View the IP address that DHCP has assigned to the server module SP.

3. Follow the instructions in To View or Configure the IP Address for the Server Module SP Using Static IP Addresses -- Through the CMM, starting with Step 3.

Connecting a Remote Console or Remote KVMS

These procedures are described in the Sun Integrated Lights Out Manager 2.0 Supplement for Sun Blade T6340 Server Modules, 820-3904 and chapter 12 of the Sun Integrated Lights out Manager 2.0 User’s Guide, 820-1188.

Note - You should first read the Sun Integrated Lights Out Manager 2.0 Supplement for Sun Blade T6340 Server Modules, 820-3904. That guide describes remote connection procedures specific to the Sun Blade T6340 server module.

Switching Between the ILOM Prompt and the System Console

The service processor has two management ports, serial and network (Ethernet). If the system console is directed to use the serial management and network management ports (the default configuration), these ports provide access to both the system console and the ILOM command-line interface (the ILOM service processor prompt), each on a separate channel (FIGURE 2-5).

FIGURE 2-5 Separate System Console and Service Processor Channels

This illustration is a conceptual diagram. [ D ]

You can switch between the ILOM service processor prompt and the system console at any time. However, you cannot access both at the same time from a single terminal window or shell tool.

The prompt displayed on the terminal or shell tool tells you which channel you are accessing:

The # or % prompt indicates that you are at the system console and that the Solaris OS is running.

The ok prompt indicates that you are at the system console and that the server is running under OpenBoot firmware control.

The -> prompt indicates that you are at the service processor.

Note - If no text or prompt appears, it might be because no console messages were recently generated by the system. Pressing the terminal’s Enter or Return key should produce a prompt.

To Switch Between the ILOM Prompt and the System Console

1. Establish an ILOM service processor session.

2. To connect to the system console, at the ILOM command prompt, type:

-> start /SP/console

The start /SP/console command switches you to the system console.

3. To switch back to the -> prompt, type the #. (Hash-Period) escape sequence.

ok #.

Connecting to the Server Module With a Local Graphics Monitor or Local KVMS

After initial system installation, you can install a local graphics monitor and configure it to access the system console. You cannot use a local graphics monitor to perform initial system installation, nor can you use a local graphics monitor to view power-on self-test (POST) messages.

To install a local graphics monitor, you must have the following items:

Monitor with appropriate resolution to support the frame buffer

Supported USB keyboard

Supported USB mouse

To view a list of supported screen resolutions type:

host% fbconfig -res \?

For more information about graphics support, see Appendix B of the Sun Blade T6340 Server Module Service Manual, 820-3902.

To Access the System Console Through a Local Graphics Monitor

1. Attach the monitor video cable to the HD-15 video connector on the cable dongle.

Tighten the thumbscrews to secure the connection.

2. Connect the monitor power cord to an AC outlet.

3. Connect the USB keyboard cable to one USB connector on the cable dongle.

4. Connect the USB mouse cable to the other USB connector.

5. Access the ok prompt.

For more information, see To Obtain the ok Prompt.

6. Set the OpenBoot configuration variables.

From the existing system console, type:

ok setenv input-device keyboard
ok setenv output-device screen

7. To cause the changes to take effect, type:

ok reset-all

The system stores the parameter changes, and boots automatically when the OpenBoot configuration variable auto-boot? is set to true (the default value).

Note - To cause the parameter changes to take effect, you can also power cycle the system using the front panel Power button.

You can now issue system commands and view system messages using your local graphics monitor. Continue with your installation or diagnostic procedure, as needed.

For more information about graphics configurations, see Appendix B of the Sun Blade T6340 Server Module Service Manual, 820-3902.

Changing the ILOM Password

1. At the initial login prompt on the server module SP, log in using the default administrator user name and password:

hostname login: root
Password: changeme

2. Use the ILOM password command to change the password.

-> set /SP/users/root password 
Enter new password: ******* 
Enter new password again: ******* 
->

After the root password has been set, on subsequent reboots, the ILOM CLI login prompt is displayed.

Powering On the Host

After the service processor boots, the ILOM CLI prompt (->) is displayed the first time the service processor is booted.

1. Type the start /SYS command.

You see an ILOM -> prompt on the system console. This indicates that the system has reset. Issue the start /SYS command:

-> start /SYS 
Are you sure you want to start /SYS (y/n)? y
Starting /SYS

2. Type the start /SP/console command.

-> start /SP/console 
Are you sure you want to start /SP/console (y/n)? y
Serial console started.  To stop, type #.
 
0:0:0>Scrub Memory....Done 
0:0:0>SPU CWQ Tests...Done
0:0:0>MAU Tests...Done

The system may take six to 15 minutes to run POST diagnostics and boot. After you type the start commands, the CPU and memory controllers initialize, and eventually the OpenBoot PROM (OBP) firmware initializes. If a boot device installed with the Solaris OS is accessible locally, that device will be booted. Otherwise, the system will use the boot net command to seek a boot device on the network.

To Power on the Server Module Manually

You can also use a pointed object or stylus to press and release the recessed Power button on the server front panel.

When main power is applied to the full server, the Power/OK LED above the Power button lights and remains lit.

To Shut Down Main Power Mode

To power off the server from main power mode, use one of the following two methods:

Graceful shutdown. Use a pointed object or other stylus to press and release the Power button on the front panel. This causes Advanced Configuration and Power Interface (ACPI) enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI-enabled operating systems will shut down to standby power mode immediately.

Emergency shutdown. Press and hold the Power button for four seconds to force main power off and enter standby power mode.

When main power is off, the Power/OK LED on the front panel will begin flashing, indicating that the server is in standby power mode.

Note - To power off the server completely, you must either remove the server module from the chassis or disconnect the AC power cords from the back panel of the chassis.

Installing the Solaris Operating System on a Hard Drive

The basic configuration of the Sun Blade T6340 server module ships with or without hard drives. If you ordered an optional hard drive with preinstalled software, refer to Preinstalled Software.

If you ordered an optional hard drive without preinstalled software and want to install the Solaris OS on the hard drive in slot 0, you must install the operating system from your network.

For instructions on how to install the operating system from the network, refer to the Solaris Installation Guide: Network-Based Installations. You can obtain this guide at:

http://docs.sun.com/

JumpStart Server Installation

You can use a JumpStart server to install the OS. A JumpStart server consists of several components:

Install client - The target system to be installed or upgraded.

Boot server - The network providing a failsafe operating system to the installing client.

The boot image is architecture independent, providing basic operating system services to all hardware supported by that operating system release. The Boot Server provides RARP, TFTP and bootparam services.

Configuration server - A system that helps client systems determine unique profile information.

Partition sizes, lists of software components to install, begin, and finish scripts are specified in a profile served by the configuration server.

Install server - The source of the software packages to be installed on the client.

Note - The boot server, configuration server, and install server can be one server.

JumpStart Server Configuration

Specific instructions on how to configure a JumpStart server are out of the scope of this document. However, configuring the JumpStart server consists of the following tasks:

1. Load the Solaris OS.

2. Create the configuration server.

3. Create the configuration files.

4. Verify the configuration file syntax.

5. Share the installation directory.

6. Start the NFS server.

7. Configure the client access.

The configuration and use of the JumpStart server depends on the configuration of your network. For a full explanation of these steps and instructions on how to configure the JumpStart server, refer to the following documents:
