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
11.6.3
BIOS 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.html
information.

Default 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.
