Dell 2 manual Accessing CMC Using Racadm, Logging in to CMC Using Public Key Authentication

After you configure your management station terminal emulator software and managed node BIOS, perform the following tasks to log in to CMC:

1.Connect to CMC using your management station terminal emulation software.

2.Type your CMC user name and password, and then press <Enter>. You are logged in to CMC.

Accessing CMC Using RACADM

RACADM provides a set of commands that allow you to configure 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 classified 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 firmware RACADM, you can the RACADM implementation that is part of the CMC firmware.

You can use remote RACADM commands in scripts to configure 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 configuring multiple CMCs, see Configuring 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
