68 Configuring CMC to Use Command Line Consoles
(For an illustration of the placement of IOMs in the chassis, see Figure 11-1.)
When you reference the IOMs in the connect command, the IOMs are
mapped to switches as shown in Table 3-4.
NOTE: There can only be one IOM connection per chassis at a time.
NOTE: You cannot connect to pass-throughs from the serial console.
To connect to a managed server serial console, use the connect server-nx
command, where n is 1-8 and x is a, b, c, or d. You can also use the racadm
connect server-n command. When you connect to a server using the -b
option, binary communication is assumed and the escape character is
disabled. If the iDRAC is not available, you see a No route to host error
message.
The connect server-n command enables the user to access the server's serial
port. After this connection is established, the user can see the server's console
redirection through CMC's serial port that includes both the BIOS serial
console and the operating system serial console.
NOTE: To see the BIOS boot screens, serial redirection has to be enabled in the
servers’ BIOS Setup. Also, you must set the terminal emulator window to 80x25.
Otherwise, the screen is garbled.
NOTE: Not all keys work in the BIOS setup screens, so provide appropriate escape
sequences for CTRL+ALT+DEL, and other escape sequences. The initial redirection
screen displays the necessary escape sequences.
