Intel MPCBL0001 Executing the Script referencecfg, Bios and OS Configuration, Default Behavior

Serial Over Lan (SOL)

HostIP = IP address of the ethernet interface on the IPMC (MPCBL0001 blade) that has been configured for SOL access.

UserName = User name of an authorized SOL client user. The configuration helper “reference_cfg” creates such a client with UserName = solusername.

Password = Password assigned for ‘UserName’. The configuration helper “reference_cfg” assigns Password = soluserpassword for UserName = solusername.

Note: Using the “-C 0” parameter can be helpful when testing or investigating SOL connectivity issues. This forces the use of CipherSuite 0, which means that all text, including exchange of the session password, will be in clear text. If this is not specified, ipmitool and the IPMC will negotiate to use the highest security compatible cipher suite.

For more information on the ipmitool, see http://ipmitool.sourceforge.net

11.6.3BIOS and OS Configuration

If a user requires access to BIOS setup menus via SOL, the BIOS must be configured manually for SOL.

In the BIOS configuration menu, “Redirection After BIOS POST” shall be set to “ALWAYS”. The terminal type should be “ANSI” and the “Send Carriage Return” and “VT-UTF8 Combo Key Support” options should both be disabled. The serial channel must be set to hardware flow control, and a bit rate of 9.6 kbps.

Note: The BIOS bit rate must match the rate configured by the reference script.

All BIOS settings listed above must be set manually. The SOL configuration script does not alter BIOS settings, only IPMC settings.

If a user requires access to the operating system (OS) via SOL, the OS must be configured for SOL. OS configuration for SOL is outside of the scope of this document. Areas of configuration required for operating systems include the boot loader, kernel, serial port (bit rate, start/stop/data bits, flow control, interrupts), a login monitoring process (for example, getty), and serial-aware utilities. See http://www.faqs.org/docs/Linux-HOWTO/Remote-Serial-Console-HOWTO.htmlfor more information.

11.7.1Default Behavior

To configure a blade for SOL communications, many configurations are required (for example, user information, channel parameters, LAN parameters, and SOL parameters). Most of the values used for configuration appear as hard-coded default values.
