Connecting to Servers or I/O Module Using Connect Command
CMC can establish a connection to redirect the serial console of a server or I/O module.
For servers, serial console redirection can be accomplished using:
• CMC command line interface (CLI) or the RACADM connect command. For more information about running the
RACADM commands, see the
Chassis Management Controller for PowerEdge VRTX RACADM Command Line
Reference Guide
.
• iDRAC Web interface serial console redirection feature.
• iDRAC Serial Over LAN (SOL) functionality.
In a serial, Telnet, SSH console, CMC supports the connect command to establish a serial connection to a server or
I/O module. The server serial console contains both the BIOS boot and setup screens, and the operating system serial
console. For the I/O module, the switch serial console is available. There is a single IOM on the chassis.
CAUTION: When run 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) will not
result in you exiting the application.
NOTE: If the 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><\>.
To connect to an IOM:
connect switch-n
where n is an IOM label A1.
When you reference the IOM in the connect command, the IOM is mapped to switch as shown in the following table.
Table 24. Mapping IO Module to Switches
IO Module Label Switch
A1 switch-a1 or switch- 1
NOTE
: At a time, there can be only one IOM connection per chassis.
NOTE: You cannot connect to pass-throughs from the serial console.
To connect to a managed-server serial console, run the command connect server-n, where n is 1–4. You can also
use the
racadm connect server-n command. When you connect to a server using the -b option, binary
