Using DHCP to Establish an IP Address

Using a Static IP Address

Note: Both options require the use of the CMC's serial port, refer to Figure 1-6 on page 8.
For DHCP, you must determine the IP address that the CMC has been assigned; for a static IP,
you must also configure the CMC to use the desired static IP address.
To use the serial port connection, you must attach and properly configure a micro-USB cable to
the CMC's "CONSOLE" port. Configure the serial port as described in "Serial Console Hardware
Requirements" on page 9.
When the serial port session is established, the console will show a CMC login, and the user can
login to the CMC as user "root" with password "root".
To determine the IP address assigned to the CMC, you must first establish a connection to the
CMC serial port (as indicated in the section "Serial Console Hardware Requirements" on page 9),
and run the command "ifconfig eth0". This will report the IP address that the CMC is
configured to use.
Running the CMC with DHCP is not recommended as the preferred option for SGI UV 2000
systems. The nature of DHCP makes it difficult to determine the IP address of the CMC, and it
is possible for that IP address to change over time, depending on the DHCP configuration usage.
The exception would be a configuration where the system administrator is using DHCP to assign
a "permanent" IP address to the CMC.
To switch from a static IP back to DHCP, the configuration file
/etc/sysconfig/ifcfg-eth0 on the CMC must be modified (see additional instructions
in the "Using a Static IP Address" section). The file must contain the following line to enable use
of DHCP:
BOOTPROTO=dhcp
To configure the CMC to use a static IP address, the user/administrator must edit the configuration
file /etc/sysconfig/ifcfg-eth0 on the CMC. The user can use the "vi" command
(i.e. "vi /etc/sysconfig/ifcfg-eth0") to modify the file.
The configuration file should be modified to contain these lines:
