Accessing CMC Using RACADM
RACADM provides a set of commands that allow you to congure and manage CMC through a text-based interface. RACADM can be
accessed using a Telnet/SSH or serial connection, using the Dell CMC console on the KVM, or remotely using the RACADM command line
interface installed on a management station.
The RACADM interface is classied as:
• Remote RACADM — Allows you to run RACADM commands on a management station with the -r option and the DNS name or IP
address of the CMC.
NOTE: Remote RACADM is included on the Dell Systems Management Tools and Documentation DVD and is installed on a
management station.
• Firmware RACADM — Allows you to log in to the CMC using Telnet, SSH, or a serial connection. With rmware RACADM, you can the
RACADM implementation that is part of the CMC rmware.
You can use remote RACADM commands in scripts to congure multiple CMCs. You cannot run the scripts directly on the CMC web
interface, because CMC does not support it.
For more information about RACADM, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference
Guide.
For more information about conguring multiple CMCs, see Conguring Multiple CMCs Using RACADM.
Logging in to CMC Using Public Key Authentication
You can log in to the CMC over SSH without typing a password. You can also send a single RACADM command as a command line
argument to the SSH application. The command line options behave similar to the remote RACADM, because the session ends after the
command is completed.
Before logging in to CMC over SSH, make sure that the public keys are uploaded. To use this feature, you must have an Enterprise License.
For example:
• Logging in: ssh service@<domain> or ssh service@<IP_address>, where IP_address is the CMC IP address.
• Sending RACADM commands: ssh service@<domain> racadm getversion and ssh service@<domain> racadm
getsel
When you log in using the service account, if a passphrase was set up when creating the public or private key pair, you may be prompted to
enter that passphrase again. If the passphrase is used with the keys, client systems running Windows and Linux provide methods to
automates the method. On client systems running Windows, you can use the Pageant application. It runs in the background and makes
entering the passphrase transparent. For client systems running Linux, you can use the ssh agent. For setting up and using either of these
applications, see their product documentation.
