6.5 Configuring Network Access

You must configure network access after connecting to the ILOM using a serial connection or an Ethernet connection.

Note:

Oracle recommends that you use an Ethernet connection if reconfiguration of network access becomes necessary.

This section contains the following topics:

• Using a Serial Connection
  
• Using the Ethernet Connection
  
• Using ipmitool Commands When SP Network Information Is Lost
  
• Configuring ILOM IP Addresses Manually
  

6.5.1 Using a Serial Connection

1. Connect to the ILOM using a serial connection, as described in Connecting to ILOM via a Serial Connection.

2. Run the following commands at the ILOM command prompt:

   cd /SP/network

   set pendingipdiscovery=static

   set pendingipaddress=<ip_address>

   set pendingipnetmask=<ip_netmask>

   set pendingipgateway=<ip_gateway>

   set commitpending=true

6.5.2 Using the Ethernet Connection

1. Connect to the ILOM using the Ethernet connection, as described in Connecting to ILOM via the Network.

2. Run the following commands at the ILOM command prompt:

   cd /SP/network

   set pendingipdiscovery=static

   set pendingipaddress=<ip_address>

   set pendingipnetmask=<ip_netmask>

   set pendingipgateway=<ip_gateway>

   set commitpending=true

6.5.3 Using ipmitool Commands When SP Network Information Is Lost

If the service processor (SP) network information gets lost, you can use an SSH shell to connect to the ETH0 interface of the operating system on the Exalytics host and run the appropriate ipmitool commands to reconfigure network settings, as in the following example:

/usr/sbin/ipmitool sunoem cli 'set /SP/users/root password=somepasswd' somepasswd

This example resets the ILOM root password.

Note:

• On Exalytics images 1.x.x.x, the ipmitool command path is /usr/bin/ipmitool sunoem CLI set /SP/users/root password=somepasswd. This example sets the ILOM root password to somepasswd.

• For more information about ipmitool commands and options, see the ipmitool man page at the following URL: http://sourceforge.net/p/ipmitool/wiki/coding_standards/

6.5.4 Configuring ILOM IP Addresses Manually

If ILOM IP addresses get misconfigured, you can configure ILOM IP addresses manually. Under normal circumstances, you do not need to configure ILOM IP addresses manually.

To configure IP addresses manually, complete the following steps:

1. Obtain a free static IP address from the network to which the Exalytics machine is connected.

2. Configure the IP address by using a serial port connection as follows:

   1. Establish a serial connection to the SP of a compute node by inserting a serial cable into the SER MGT port on the rear of the compute node.

   2. In the terminal window, configure the following settings:

      8N1: Eight data bit, no parity, one stop bit

      9600 Baud

      Disable hardware control

      Disable software control

   3. At the login prompt, enter root as the user name, and welcome1 as the password.

   4. From your present working directory, use the cd command to move to the /SP/network directory, as shown in Figure 6-1.

   5. Run the following commands at the command prompt:

      cd /SP/network

      set pendingipdiscovery=static

      set pendingipaddress=<ip_address>

      set pendingipnetmask=<ip_netmask>

      set pendingipgateway=<ip_gateway>

      set commitpending=true
