Connecting to Oracle ILOM

This section describes how to configure the IP address for the server using Oracle Integrated Lights Out Manager (ILOM). It contains the following topics:

• Network Defaults

• Log In to Oracle ILOM Using a Local Serial Connection

• Log In to Oracle ILOM Using a Remote Ethernet Connection

• Modify Network Settings From the Oracle ILOM CLI

• Modify Network Settings From the Oracle ILOM Web Interface

• Test IPv4 or IPv6 Network Configuration From the Oracle ILOM CLI

• Test IPv4 or IPv6 Network Configuration From the Oracle ILOM Web Interface

• Exit Oracle ILOM

Network Defaults

The Sun Server X2-4 supports dual-stack IPv4 and IPv6 settings, which enable Oracle 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 server. 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 enable you to test that the assigned settings are working correctly and to establish a connection to Oracle ILOM locally and remotely.

To log in locally, see Log In to Oracle ILOM Using a Local Serial Connection.

To log in remotely, use the IP address, hostname, or IPv6 local link name assigned to the server SP and follow the instructions in Log In to Oracle ILOM Using a Remote Ethernet Connection.

Log In to Oracle ILOM Using a Local Serial Connection

This procedure does not require that you know the IP address of the server SP. It does require that you have an Oracle ILOM Administrator account.

1. Verify that your serial console connection to the server is secure and operational.
2. Ensure that the following serial communication settings are configured:
   • 8N1: eight data bits, no parity, one stop bit
   • 9600 baud
   • Disable hardware flow control (CTS/RTS)
3. Press Enter to establish a connection between your serial console and Oracle ILOM.

   A login prompt to Oracle ILOM appears.

4. Log in to the Oracle ILOM command-line interface (CLI) using an Administrator account.

   Oracle ILOM displays a default command prompt (->), indicating that you have successfully logged in to Oracle ILOM.

Log In to Oracle ILOM Using a Remote Ethernet Connection

This procedure requires that you have an Oracle ILOM Administrator account and that you know the IP address or hostname of the server SP.

1. Establish a connection to Oracle ILOM.
   • Command-line interface (CLI): Using a secure shell session, specify your Administrator account user name and the IP address or hostname of the server. For example, type ssh username@host, where host is either the IP address or hostname of the server SP (when using DNS).

     The Oracle ILOM password prompt appears.

   • Web browser user interface (BUI): Type the IP address of the server in the address field of your web browser and press Enter.

     The Oracle ILOM web login page appears.

2. Follow the relevant step below to complete the login process.
   • CLI: At the Oracle ILOM password prompt, type your password and press Enter. For example:

     Password: changeme

     Oracle ILOM displays a default command prompt (->), indicating that you have successfully logged in to Oracle ILOM.

   • BUI: In the ILOM web login page, type your user name and password, and click Log In.

     The Summary page appears, indicating that you have successfully logged in to Oracle ILOM.

Modify Network Settings From the Oracle ILOM CLI

If you want to modify the network settings currently configured for the server from the Oracle ILOM CLI, use the following procedure.

1. Log in to the Oracle ILOM CLI using the relevant method in Log In to Oracle ILOM Using a Local Serial Connection or Log In to Oracle ILOM Using a Remote Ethernet Connection.

   ---

   Note - If you log in to Oracle ILOM using an Ethernet connection, after you modify the network settings, your connection will be terminated, and you will have to log back in using the new settings.

   ---

2. Perform the network configuration instructions that apply to your network environment, then test the network settings:
   • To view or configure IPv4 network settings, perform Step 3 through Step 4.
   • To view or configure IPv6 network settings, perform Step 5 through Step 8.
   • To test the IPv4 or IPv6 network settings, see Test IPv4 or IPv6 Network Configuration From the Oracle ILOM CLI.
3. For IPv4 network configurations, use the cd command to navigate to the /SP/network directory:

   -> cd /SP/network

4. Do one of the following:
   • If you have a DHCP server on the network, type the following command to view the settings assigned to the server by the DHCP server:

     -> show /SP/network

   • If there is no DHCP server, or if you want to assign settings, use the set command to assign values for the properties listed in the following table. For example:

     -> set /SP/network/ pendingipdiscovery=static

     -> set /SP/network/ pendingipaddress=10.8.183.106

     -> set /SP/network/ pendingipnetmask=255.255.255.0

     -> set /SP/network/ pendingipgateway=10.8.183.254

     -> set /SP/network/ commitpending=true

     
     

     Property Set Property Value Description state set state=enabled The network state is enabled by default. pendingipdiscovery set pendingipdiscovery=static To enable a static network configuration, set pendingipdiscovery to static. By default, pendingipdiscovery is set to dhcp. pendingipaddress pendingipnetmask pendingipgateway set pendingipaddress= <ip_address> pendingipnetmask=<netmask> pendingipgateway=<gateway> To assign multiple static network settings, type the set command followed by the pending command for 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 changes.

   ---

   Note - If you are logged in to Oracle ILOM using an Ethernet connection, when you set commitpending to true to commit the changes to the network settings, your Oracle ILOM connection will be terminated and you will have to log back in using the new settings.

   ---

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

   -> cd SP/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
   /SP/network/ipv6
   Targets:
    
   Properties:
    state = enabled
    autoconfig = stateless
    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:
   

   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 autoconfig value you want to set. Options include: stateless (default setting) Automatically assigns IP address learned from IPv6 network router. dhcpv6_stateless Automatically assigns DNS information learned from the DHCPv6 server.The dhcpv6_stateless property value is available in Oracle ILOM as of 3.0.14. dhcpv6_stateful Automatically assigns the IPv6 address learned from the DHCPv6 server.The dhcpv6_stateful property value is available in Oracle ILOM as of 3.0.14. 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 /network target.

   ---

   ---

   Note - You can enable the stateless auto-configuration option to run at the same time as when the option for dhcpv6_stateless is enabled or as when the option for dhcpv6_stateful is enabled. However, the auto-configuration options for dhcpv6_stateless and dhcpv6_stateful should not be enabled to run at the same time.

   ---

8. To set a static IPv6 address, complete these steps:
   1. Specify the following property types:
      

      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 =<ipv6_address>/<subnet mask length in bits> Type this command followed by the property value for the static IPv6 address and netmask that you want to assign to the device.IPv6 address example:fec0:a:8:b7:214:4f ff:feca:5f7e/64

   2. Commit the pending IPv6 static network parameters by typing the following command:

      -> set commitpending=true

   ---

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

   ---

9. Test the IPv4 or IPv6 network configuration from Oracle ILOM using the Network Test Tools (Ping and Ping6).

   For details, see Test IPv4 or IPv6 Network Configuration From the Oracle ILOM CLI.

Modify Network Settings From the Oracle ILOM Web Interface

If you want to modify the network settings currently configured for the server from the Oracle ILOM web interface, use the following procedure.

1. Log in to the Oracle ILOM web interface using the relevant steps in Log In to Oracle ILOM Using a Remote Ethernet Connection.
2. Select ILOM Administration > Connectivity from the navigation tree on the left.

   The Network Settings page appears. The settings configured on your device are displayed.

   
   
3. Perform the network configuration instructions that apply to your network environment:
   • IPv4: To allow the DHCP server on your network to assign network settings, ensure that the DHCP radio button is selected and click Save.
   • IPv4: To assign network settings, select the Static radio button and fill in the IP Address, Netmask, and Gateway fields. Then, click Save.
   • IPv6: To configure an auto-configuration option, ensure that the Enabled check box next to the State property is selected. Then, select an auto-configuration value and click Save.

     ---
