7.7 Reconfigure the Network Access

This step is required only if your network access must be reconfigured. You can reconfigure 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:

7.7.1 Reconfigure the Network Access Using a Serial Connection

  1. Connect to the ILOM using a serial connection, as described in Connect to ILOM via a Serial Connection.
  2. Run the following commands at the ILOM command prompt:

    set pendingipdiscovery=static

    set pendingipaddress=<ip_address>

    set pendingipnetmask=<ip_netmask>

    set pendingipgateway=<ip_gateway>

    set pendingmanagementport=/SYS/MB/NET0

    set commitpending=true

7.7.2 Reconfigure the Network Access Using the Ethernet Connection

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

    Note:

    An Ethernet cable is pre-wired in the Exalogic machine for this purpose.

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

    set pendingipdiscovery=static

    set pendingipaddress=<ip_address>

    set pendingipnetmask=<ip_netmask>

    set pendingipgateway=<ip_gateway>

    set pendingmanagementport=/SYS/MB/NET0

    set commitpending=true

7.7.3 Use the 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 compute node and run appropriate ipmitool commands to reconfigure network settings, as in the following example:

/opt/ipmitool/bin/ipmitool sunoem cli 'set /SP/users/rootpassword=somepasswd' somepasswd

This example resets the ILOM root password.

Note:

For more information about ipmitool commands and options, navigate to the /opt/ipmitool/bin/ directory and run man ipmitool.

7.7.4 Configure ILOM IP Addresses Manually

If ILOM IP addresses get misconfigured due to Oracle Exalogic Configuration Utility failures, 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 Cisco 4948 switch is connected.

  2. Configure the IP address and sideband management 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, log in as the root user.

    4. From your present working directory, use the cd command to move to the /SP/network directory, as shown in Figure 7-2.

    5. Run the following commands at the command prompt:

      set pendingipdiscovery=static

      set pendingipaddress=<ip_address>

      set pendingipnetmask=<ip_netmask>

      set pendingipgateway=<ip_gateway>

      set pendingmanagementport=/SYS/MB/NET0

      set commitpending=true
