Configuring the Sun Blade 6048 Modular System Management Network

This chapter describes how to configure the chassis monitoring module (CMM) with an IP address using the Sun Integrated Lights Out Manager (ILOM). Specifically, it walks you through the steps of establishing a connection with a CMM using ILOM. It then describes how to configure the CMM with static or dynamic (DHCP) IP addresses.

Note - The instructions and illustrations in this chapter refer to installing modules into one of the four subassemblies in the Sun Blade 6048 chassis. The instructions for each shelf are identical.

Topics discussed in this chapter include:

What Is Integrated Lights Out Manager?

The Integrated Lights Out Manager (ILOM) is a built-in system management tool that enables you to monitor and manage the components installed in a Sun Blade 6048 shelf. The ILOM is accessed through the CMM service processor. For instance, in the CMM ILOM, you can configure network information, view and edit hardware configurations, monitor vital system information, and manage user accounts.

Note - The term CMM ILOM in this document refers to the ILOM that runs on the Sun Blade 6048 shelf CMM service processor. For information about server management systems specific to the server modules installed in the Sun Blade 6048 chassis, see the server module documentation. Some server modules that are installed in the Sun Blade 6048 shelf might use a different management software.

The CMM ILOM is accessible through command-line interfaces (CLI), the ILOM web interface, and IPMI.

Any user with a valid user account can access the CMM ILOM. The first time you access the CMM ILOM, you need to use the preconfigured ILOM administrator account.

For more information about the tasks that you can perform in the CMM ILOM, see the Sun Integrated Lights Out Manager 2.0 User’s Guide, 820-1188. For more information about the preconfigured ILOM administrator account, see About the Preconfigured CMM ILOM Administrator Account.

About the Preconfigured CMM ILOM Administrator Account

Each Sun Blade 6048 shelf includes one preconfigured CMM ILOM administrator account with the following log in:

User name: rootPassword: changeme

You cannot change the preconfigured administrator account (root) other than changing its default password. This account offers built-in administrative privileges (read and write access) to all CMM ILOM functions, features, and commands.

The first time you access ILOM at the CMM level or server module level you need to log in as root with the default password changeme. After you have logged in to the CMM ILOM and established network connectivity to the system, change the password associated with the ILOM root account to prevent your system from unauthorized access.

For more information about resetting the ILOM root account password, see Changing the CMM ILOM Root Account Default Password.

Establishing an Initial Connection to the CMM ILOM

To set up CMM and server modules with initial network configuration information, you must establish a connection through ILOM to the CMM.

Until the CMM has an IP address assigned to it, you must use a serial connection to communicate with the CMM. After establishing a serial connection to the CMM, you can choose to configure the CMM and server modules with static or DHCP IP addresses.

This section includes the following topics:

Assigning IP Addresses for the First Time

Communicating With the CMM ILOM Using the Management Network IP Addresses

Assigning IP Addresses for the First Time

This section includes the following topics:

To Use DHCP to Assign the CMM IP Addresses Initially

To Assign a Static IP Address to a CMM

Prerequisites

Before assigning IP addresses, ensure that you have completed the following installation tasks:

Unpacked and completed the hardware and cabling setup of the Sun Blade 6048 modular system. For details, see Chapter 1, Chapter 2, and Chapter 3.

Attached an Ethernet cable to the NET MGT port on the rear panel of the CMM of the Sun Blade 6048 shelf. For details, see To Attach CMM Network and Serial Console Cables.

Established console access to the CMM (or server module) through a serial connection. For details, see To Attach CMM Network and Serial Console Cables.

Configured serial settings:

8N1: eight data bits, no parity, one stop bit

9600 baud

Disable hardware flow control (CTS/RTS)

Disable software flow control (XON/XOFF)

Ensured that the main power was applied to the chassis and the server modules. For details, see Powering On the System Shelf for the First Time.

Note - If you intend to have DHCP IP addresses assigned, you need to have an established DHCP server on the same local network as the Sun Blade 6048 modular system. Setting up a DHCP server is out of the scope of this guide. See the documentation supplied with the DHCP server software.

To Use DHCP to Assign the CMM IP Addresses Initially

When you first apply power, the CMM ILOM broadcasts a DHCP request for an IP address. If a DHCP server receives this request, it will supply an address and other network information. If server modules are powered up at the same time, they also broadcast the DHCP request and receive individual IP addresses.

Note - Refer to the server module documentation for information about assigning a DHCP address to a server module SP.

Follow these instructions when using DHCP to assign IP addresses:

1. Make sure that your DHCP server is configured to accept new media access control (MAC) addresses. Refer to the documentation supplied with your DHCP server software.

2. Make sure that the Ethernet cable is plugged into the NET MGT port on the active CMM.

As long as the CMM ILOM was not configured previously with a static IP, the CMM ILOM automatically broadcasts a DHCPDISCOVER packet with the ID of its CMM MAC address and server module MAC addresses.

The DHCP server on your network returns the DHCPOFFER packet containing the IP address and other information. The CMM then manages its “lease” of IP addresses assigned by the DHCP server.

3. To obtain the DHCP IP addresses assigned to the CMM and server module SPs via the CMM serial connection:

a. Using a serial console attached to the rear panel of the CMM, log in to the CMM ILOM as the administrator.

The preconfigured administrator username is root and its default password changeme.

b. To set the working directory for the active CMM, type:
cd /CMM/network

c. To view the active CMM IP address, type:
show

Note - You can also view the IP addresses via the DHCP server logs. Refer to the DHCP server documentation for details.

To Assign a Static IP Address to a CMM

If you want to use static addresses instead of the dynamic addresses provided by your DHCP server, you can assign the static IP address at the following times:

Before attaching a LAN cable to the NET MGT port of the CMM.

After the modules have been assigned an DHCP IP address. You can change the DHCP assigned address to a static IP address.

Follow these instructions when assigning a static IP address to a CMM through a serial connection:

1. Verify that your serial connection to the active CMM is operational.

For information about attaching a serial console to a CMM, see To Attach CMM Network and Serial Console Cables.

2. Log in to the CMM ILOM as an administrator by entering an administrator user name (default: root) and password (default: changme), and then press Enter.

The default prompt appears (->), and the system is ready for you to run the CLI commands to establish network settings.

3. To set a static IP address on the CMM through ILOM using the CLI, type the following command to set the working directory:

cd /CMM/network

4. Use the following commands to specify the IP, netmask, and gateway addresses.

Command	Description and Example
`set pendingipaddress=`	Type this command followed by the static IP address that you want to assign to the CMM. Example: Typing `set pendingipaddress=129.144.82.26` tells ILOM to assign `129.144.82.26` as the CMM IP address.
`set pendingipnetmask=`	Type this command followed by the static netmask address that you want to assign to the CMM. Example: Typing `set pendingipnetmask=255.255.255.0` tells ILOM to assign `255.255.255.0` as the CMM netmask address.
`set pendingipgateway=`	Type this command followed by the static gateway address that you want to assign to the CMM. Example: Typing `set pendingipgateway=129.144.82.254` tells ILOM to assign `129.144.82.254` as the CMM gateway address.
`set pendingipdiscovery=`	Type the following command to tell ILOM whether you want to set a static IP address. `set pendingipdiscovery=static`
`set commitpending=true`	Type this command (`true)` to assign the network settings specified. Example: `set pendingipaddress=129.144.82.26` `set pendingipnetmask=255.255.255.0` `set pendingipgateway=129.144.82.254` `set commitpending=true`

Communicating With the CMM ILOM Using the Management Network IP Addresses

After the CMM has been assigned IP addresses, use these IP addresses to communicate with the CMM ILOM. Specifically, the management network IP address is the IP address assigned to the service processor of the CMM.

In addition to the management network IP addresses, you will also have IP addresses associated with the data network. The data network IP addresses are configured after you install the host operating system on a server module. It is important to distinguish the data network IP addresses from the management network IP addresses since they serve different purposes.

You need to specify the IP address of the CMM when you want to perform management operations at the chassis level. To perform management operations at a server module level, you need to specify the IP addresses of the server module service processor.

For further information about specifying IP addresses for the server modules, refer to the server module documentation. For more information about management tasks that you can perform at the chassis level, see the Sun Integrated Lights Out Manager 2.0 User’s Guide, 820-1188.

Changing the CMM ILOM Root Account Default Password

The following procedures describe how to change the default password for the ILOM using the CLI or the ILOM web interface.

For information about creating new user accounts and assigning a role (privileges) to a user account, see the Sun Integrated Lights Out Manager 2.0 User’s Guide,
820-1188, and the documentation for the server modules that you have installed.

To Change the Password Using the CLI

To change the changeme password:

1. Using a serial console attached to the rear panel of the CMM, log in to the CMM ILOM as the administrator at the login prompt.
