About The Oracle Integrated Lights-Out Manager

The following topics are covered in this section:

- ILOM Overview

- Preconfigured CMM ILOM Administrator Account

- ILOM Documentation

### ILOM Overview

The Integrated Lights Out Manager (ILOM) is a built-in system management tool that enables you to monitor and manage the components installed in the Sun Blade 6000 chassis. The ILOM is accessed through the CMM service processor. For instance, in 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 is used in this document to refer to the ILOM that runs on the Sun Blade 6000 modular system CMM service processor. For information on server management systems specific to the server modules installed in the Sun Blade 6000 chassis, see the server module documentation.

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

Some server modules that are installed in the Sun Blade 6000 chassis might use a different management software. See your server module documentation for information on server module management. Storage modules do not have a service processor and do not run ILOM. See your storage module documentation for more information on storage module management.

For more information about the tasks you can perform in the CMM ILOM, see the ILOM documentation listed at ILOM Documentation.

### Preconfigured CMM ILOM Administrator Account

The Sun Blade 6000 modular system ships with one preconfigured CMM ILOM administrator account:

User name: `root`

Password: `changeme`

The preconfigured administrator account, known as `root`, cannot be deleted or changed, 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 into 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 Password with CLI.

### Accepting Network Defaults

As of ILOM 3.0.12, the Sun Blade 6000 modular system supports dual-stack IPv4 and IPv6 settings, which enable ILOM to fully operate in an IPv4 and IPv6 network environment. For IPv4 configurations, DHCP is enabled by default, allowing a DHCP server on the network to automatically assign network settings to the CMM. For IPv6 configurations, IPv6 stateless auto-configuration is enabled by default, allowing an IPv6 router on the network to assign the network settings.

In a typical configuration, you will accept these settings assigned by the DHCP server or IPv6 router. The procedures in this section allow you to log in to ILOM to test that the assigned settings are working correctly, and also to change the settings if necessary.

### ILOM Documentation

TABLE 4-1 lists the ILOM documentation available for the Sun Blade 6000 modular system for ILOM 3.x or later. Refer to this documentation for further details on using ILOM with the Sun Blade 6000 modular system.

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 initially 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:

- Prerequisites

- Assigning an IP Address to the CMM

### Prerequisites

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

- Unpacked and completed the hardware and cabling setup of the Sun Blade 6000 modular system. For details, see Chapter 1, Chapter 2, and Chapter 3.

- Attached an Ethernet cable to the NET MGT port on rear panel of the CMM. For details, see How to Cable the CMM.

- Established console access to the CMM (or server module) through a serial connection. For details, see How to Cable the CMM.

- 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 Chassis 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 6000 modular system. Setting up a DHCP server is out of the scope of this guide. See the documentation supplied with the DHCP server software.

### Assigning an IP Address to the CMM

Before you can access the CMM ILOM through the Ethernet NET MGT port, you will need to determine the IP address assigned to the CMM. This section covers the following topics:

- How to Use DHCP to Assign All IP Addresses

- How to Assign a Static IP Address to the CMM

How to Use DHCP to Assign All IP Addresses

The CMM is set to acquire IP addresses through DHCP by default. Follow these instructions when using DHCP to assign IP addresses.

1. Verify 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. Verify that the Ethernet cable is plugged into the NET MGT port on the active CMM.

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

- 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, use one of the following methods:

- ILOM-CMM via serial connection

a. Using a serial console attached to the rear panel of the CMM, log into CMM ILOM as the administrator. At the login prompt, type the ILOM administrator username and password.

The default user name is `root` and the default password is `changeme`. `changeme`.

b. Press Enter.

c. To view the network information for the CMM, type the following command:

`->``show /CMM/network`

d. To drill view the IP addresses of each server module, type the following command:
`->``show` `/CH/BL` x`/SP/network`

BLx represents the server module installed in slot BL-0. To specify the target server module, you must specify the slot number of where the module is installed. Server module slots range from 0 to 9.

Note - Storage modules do not have a service processor. If you view storage blade information using /CH/BLx, the SP target is not shown.

- DHCP server logs.

Refer to the DHCP server documentation for details.

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

How to Assign a Static IP Address to the CMM

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 How to Cable the CMM.

2. Log into CMM ILOM as an administrator by entering an administrator user name and password, and then press Enter.

The default user name is `root` and the default password is `changeme`.

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

3. 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` would tell 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` would tell 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` would tell 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 CMM ILOM Using the Management Network IP Addresses.

The following procedures are covered in this section:

- How to Log Into the CMM Through the SER MGT Port

- How to Log Into the CMM Through the NET MGT Port

- How to Change Network Settings

- How to Test the IPv4 or IPv6 Network Configuration

### How to Log Into the CMM Through the SER MGT Port

You can only run ILOM CLI commands through the SER MGT port. You cannot run the ILOM web interface through the SER MGT port.

1. Ensure that you have cabled a terminal device to the CMM SER MGT port.

See Cabling the Chassis Monitoring Module (CMM).

2. From your terminal device, log into the CMM ILOM with a valid ILOM user account and password.

The default login account is `root` and default password is `changeme`.

Once you are logged in, you communicate with the CMM using the CMM ILOM command line interface. For CLI details, refer to the Sun Integrated Lights Out Manager (ILOM) 3.0 CLI Procedures Guide.

### How to Log Into the CMM Through the NET MGT Port

Perform this task when you want to access the CMM ILOM through your network. You can perform ILOM CLI or ILOM web interface commands.

1. Ensure that the following conditions are met:

- The CMM NET MGT is connected to your network.

- An IP address is assigned to the CMM and you know the address.

- You know a valid CMM ILOM account and password.

The default login account is `root` and default password is `changeme`.

2. Do one of the following:

- To log into the ILOM CLI, type the following oommand:

`$` `ssh root`@CMM_IP_address

`Password:` CMM_root_password

The ILOM -> prompt is displayed.

- To log into the ILOM web interface:

i. Open a browser and type in the CMM ILOM IP address in the following format:

http://CMM_IP_address

ii. At the login page, enter your login and password.

The main ILOM page is displayed.

Once you are logged into the CLI or web interface, you can perform a variety of ILOM commands to administer the modular components. Refer to the ILOM documentation for more information. See ILOM Documentation.

### How to Change Network Settings

If you want to change the network settings currently configured for the server module, use the following procedure.

1. Log in to ILOM using one of the methods in How to Log Into the CMM Through the SER MGT Port or How to Log Into the CMM Through the NET MGT Port.

2. Perform the network configuration instructions that apply to your network environment:

- To view or configure IPv4 network settings, perform Step 3 to Step 4 in this procedure.

- To view or configure IPv6 network settings, perform Step 5 to Step 8 in this procedure.

3. For IPv4 network configurations, use the `cd` command to navigate to the `/network` directory:

->`cd /CMM/network`

4. Do one of the following:

- If you have a DHCP sever on the network, type the `show` command to view the IPv4 network settings assigned to the server module by the DHCP server.

- If there is no DHCP server, or if you want to assign static IPv4 network settings, use the `set` command to assign values for the properties listed in TABLE 4-1. For example:

    -> set pendingipdiscovery=static
    -> set pendingipaddress=10.8.183.106
    -> set pendingipnetmask=255.255.255.0
    -> set pendingipgateway=10.8.183.254
    -> set commitpending=true

TABLE 4-1 Set IPv4 static property values
Property | Set Property Value | Description
--- | --- | ---
`state` | `set state=enabled` | The network `state` is `enabled` by default for IPv4. Note - To enable the static IPv4 network option the `state` must be `set` to `enabled`.
`pendingipdiscovery` | `set pendingipdiscovery=static` | To enable a static IPv4 network configuration, you need to set the `pendingipdiscovery` property value to `static`. Note - The property value for `ipdiscovery` is set to `dhcp` by default for IPv4.
`pendingipaddress` pendingipnetmask pendingipgateway | `set pendingipaddress=<ip_address> pendingipnetmask=<netmask> pendingipgateway=<gateway>` | To assign multiple static network settings, type `set` command followed by pending command for the each property value (IP address, netmask, and gateway), then type the static value that you want to assign.
commitpending= | `set commitpending=true` | Type `set commitpending=true` to commit the changes made to the `state` and `ipdiscovery` property values.

5. For IPv6 network configurations, use the `cd` command to navigate to the `/CMM/network/ipv6` directory:

`->``cd /CMM/network/ipv6`

6. Type the `show` command to view the IPv6 network settings configured on the device.

For example, see the following `sample` output values for the IPv6 properties on a server SP device.

    -> show

     /CMM/network/ipv6
        Targets:

        Properties:
            state = enabled
            autoconfig = stateless_only
            dhcpv6_server_duid = (none)
            link_local_ipaddress = fe80::214:4fff:feca:5f7e/64
            static_ipaddress = ::/128
            ipgateway = fe80::211:5dff:febe:5000/128
            pending_static_ipaddress = ::/128
            dynamic_ipaddress_1 = fec0:a:8:b7:214:4fff:feca:5f7e/64

        Commands:
            cd
            show

7. To configure an IPv6 auto-configuration option, use the `set` command to specify the following auto-configuration property values:

TABLE 4-2 Set IPv6 auto-configuration property values
Property | Set Property Value | Description
--- | --- | ---
`state` | `set state=enabled` | The IPv6 network state is `enabled` by default. To enable an IPv6 auto-configuration option this state must be `set` to `enabled`.
`autoconfig` | `set autoconfig=`<value> | Specify this command followed by the autoconf value you want to set. Options include: stateless_only (default setting) Automatically assigns IP address learned from IPv6 network router. disable Disables all auto-configuration property values and sets the read-only property value for link local address.

Note - The IPv6 configuration options take affect after they are set. You do not need to commit these changes under the `/CMM/network` target.

8. Perform the following steps to set a static IPv6 address:

a. To set a static IPv6 address, specify the following property values:

TABLE 4-3 Set property values for IPv6 static address
Property | Set Property Value | Description
--- | --- | ---
`state` | set state=enabled | The IPv6 network state is `enabled` by default. To enable a static IP address this state must be set to `enabled`.
`pendingipaddress` | set pending_static_ipaddress=<ip6_address>/<subnet mask length in bits> | Type this command followed by the property value for the static IPv6 address and net mask that you want to assign to the device. IPv6 address example: `fec0:a:8:b7:214:4fff:feca:5f7e/64`

b. To commit the pending IPv6 static network parameters, perform the steps in the following table:

TABLE 4-4 Steps to commit pending static IPv6 address
Step | Description
--- | ---
1 | Use the `cd` command to change the directory to the device `network` target: `cd /CMM/network`
2 | Type the following command to commit the changed property values for IPv6. `set commitpending=true`

Note - Network settings are considered pending until you commit them. Assigning a new static IP address to the CMM ends all active ILOM sessions to the device. To log back in to ILOM, you will need to create a new session using the newly assigned IP address.

9. To test the IPv4 or IPv6 network configuration from ILOM use the Network Test Tools (Ping and Ping6). For details, see How to Test the IPv4 or IPv6 Network Configuration.

### How to Test the IPv4 or IPv6 Network Configuration

1. At the CLI prompt, type the `show` command to view the network `test` targets and properties.

For example, see the following output the shows the test target properties on a CMM device.

    -> show

    /CMM/network/test
       Targets:

       Properties:
           ping = (Cannot show property)
           ping6 = (Cannot show property)

       Commands:
           cd
           set
           show

2. Use the `set` `ping` or `set` `ping6` command to send a network test from the device to a specified network destination.:

Property | Set Property Value | Description
--- | --- | ---
`ping` | `set ping=<`IPv4_address`>` | Type the `set` `ping=` command at the command prompt followed by the IPv4 test destination address. For example: -> `set ping=10.8.183.106` `Ping of 10.8.183.106 succeeded`
`ping6` | `set ping6=<`IPv6_address`>` | Type the `set` `ping6=` command followed by the IPv6 test destination address. For example: -> `set ping6=fe80::211:5dff:febe:5000` `Ping of fe80::211:5dff:febe:5000 succeeded`

##

Changing the CMM ILOM Root Account Password with CLI

To change the `changeme` password, follow these steps:

1. Log into the CMM ILOM using the SER MGT or NET MGT ports. See Communicating With CMM ILOM Using the Management Network IP Addresses..

2. Change the password for the CMM by typing the following command:

`->``set /CMM/users/root password=`password

Where password is the new password that you want to assign.

For information about creating new user accounts and assigning a role (privilege) to a user account, see the ILOM documentation listed in ILOM Documentation.
