Configuring CMC to Use Command Line Consoles 67
Connecting to Servers or I/O Modules With the
Connect Command
CMC can establish a connection to redirect the serial console of server or I/O
modules. For servers, serial console redirection can be accomplished in several
ways:
• Using the CMC command line and the connect , or racadm connect
command. For more information about
connect , see the racadm connect
command in the
RACADM Command Line Reference Guide for iDRAC6
and CMC
.
• Using the iDRAC Web interface serial console redirection feature.
• Using the iDRAC Serial Over LAN (SOL) functionality.
While in a serial/Telnet/SSH console, CMC supports the connect command
to establish a serial connection to server or IOM modules. The server serial
console contains both the BIOS boot and setup screens, as well as the
operating system serial console. For I/O modules, the switch serial console is
available.
CAUTION: When executed from the CMC serial console, the connect -b option
stays connected until the CMC resets. This connection is a potential security risk.
NOTE: The connect command provides the –b (binary) option. The –b option
passes raw binary data, and cfgSerialConsoleQuitKey is not used. Additionally,
when connecting to a server using the CMC serial console, transitions in the
DTR signal (for example, if the serial cable is removed to connect a debugger)
do not cause a logout.
NOTE: If an IOM does not support console redirection, the connect command
displays an empty console. In that case, to return to the CMC console,
type the Escape sequence. The default console escape sequence is <Ctrl>\.
There are up to six IOMs on the managed system. To connect to an IOM:
connect switch-n
where n is an IOM label A1, A2, B1, B2, C1, and C2.
