Overview
Cisco Integrated Management Controller
CIMC Firmware
CIMC is a separate management module built into the motherboard. A dedicated ARM-based processor, separate from the main server CPU, runs the CIMC firmware. The system ships with a running version of the CIMC firmware. You can update the CIMC firmware, but no initial installation is needed.
Server OS
The main server CPU runs an OS such as Windows or Linux. The server ships with a pre-installed OS, but you can install a different OS using the DVD drive or over the network. You can use CIMC to install the new OS using the KVM console and vMedia.
Note You can access the available OS installation documentation from the Cisco UCS C-Series Servers Documentation Roadmap at http://www.cisco.com/go/unifiedcomputing/c-series-doc.
Cisco Integrated Management Controller
The CIMC is the management service for the C-Series servers. CIMC runs within the server.
Note The CIMC management service is used only when the server is operating in Standalone Mode. If your C-Series server is integrated into a UCS system, you must manage it using UCS Manager. For information about using UCS Manager, see the configuration guides listed in the Cisco UCS B-Series Servers Documentation Roadmap at http://www.cisco.com/go/unifiedcomputing/b-series-doc.
Management Interfaces
You can use a web-based GUI or SSH-based CLI to access, configure, administer, and monitor the server. Almost all tasks can be performed in either interface, and the results of tasks performed in one interface are displayed in another. However, you cannot do the following:
•Use CIMC GUI to invoke CIMC CLI
•View a command that has been invoked through CIMC CLI in CIMC GUI
•Generate CIMC CLI output from CIMC GUI
Tasks You Can Perform in CIMC
You can use CIMC to perform the following server management tasks:
•Power on, power off, power cycle, reset and shut down the server
•Toggle the locator LED
•Configure the server boot order
•View server properties and sensors
•Manage remote presence
|

OL-28893-01 |
Overview
CIMC CLI
•Create and manage local user accounts, and enable remote user authentication through Active Directory
•Configure network-related settings, including NIC properties, IPv4, VLANs, and network security
•Configure communication services, including HTTP, SSH, and IPMI Over LAN
•Manage certificates
•Configure platform event filters
•Update CIMC firmware
•Monitor faults, alarms, and server status
No Operating System or Application Provisioning or Management
CIMC provisions servers, and as a result, exists below the operating system on a server. Therefore, you cannot use it to provision or manage operating systems or applications on servers. For example, you cannot do the following:
•Deploy an OS, such as Windows or Linux
•Deploy patches for software, such as an OS or an application
•Install base software components, such as anti-virus software, monitoring agents, or backup clients
•Install software applications, such as databases, application server software, or web servers
•Perform operator actions, including restarting an Oracle database, restarting printer queues, or handling non-CIMC user accounts
•Configure or manage external storage on the SAN or NAS storage
CIMC CLI
The CIMC CLI is a command-line management interface for Cisco UCS C-Series servers. You can launch the CIMC CLI and manage the server over the network by SSH or Telnet. By default, Telnet access is disabled.
A user of the CLI will be one of three roles: admin, user (can control, cannot configure), and read-only.
Note To recover from a lost admin password, see the Cisco UCS C-Series server installation and service guide for your platform.
Command Modes
The CLI is organized into a hierarchy of command modes, with the EXEC mode being the highest-level mode of the hierarchy. Higher-level modes branch into lower-level modes. You use the scope command to move from higher-level modes to modes in the next lower level , and the exit command to move up one level in the mode hierarchy. The top command returns to the EXEC mode.

Overview
Command Modes
Note Most command modes are associated with managed objects. The scope command does not create managed objects and can only access modes for which managed objects already exist.
Each mode contains a set of commands that can be entered in that mode. Most of the commands available in each mode pertain to the associated managed object. Depending on your assigned role, you may have access to only a subset of the commands available in a mode; commands to which you do not have access are hidden.
The CLI prompt for each mode shows the full path down the mode hierarchy to the current mode. This helps you to determine where you are in the command mode hierarchy and can be an invaluable tool when you need to navigate through the hierarchy.

Overview
Complete a Command
Complete a Command
You can use the Tab key in any mode to complete a command. Partially typing a command name and pressing Tab causes the command to be displayed in full or to the point where another keyword must be chosen or an argument value must be entered.
Command History
The CLI stores all commands used in the current session. You can step through the previously used commands by using the Up Arrow or Down Arrow keys. The Up Arrow key steps to the previous command in the history, and the Down Arrow key steps to the next command in the history. If you get to the end of the history, pressing the Down Arrow key does nothing.
All commands in the history can be entered again by simply stepping through the history to recall the desired command and pressing Enter. The command is entered as if you had manually typed it. You can also recall a command and change it before you press Enter.
Committing, Discarding, and Viewing Pending Commands
When you enter a configuration command in the CLI, the command is not applied until you enter the commit command. Until committed, a configuration command is pending and can be discarded by entering a discard command. When any command is pending, an asterisk (*) appears before the command prompt. The asterisk disappears when you enter the commit command, as shown in this example:
Server# scope chassis
Server /chassis # set locator-led off
Server /chassis *# commit
Server /chassis #
You can accumulate pending changes in multiple command modes and apply them together with a single commit command. You can view the pending commands by entering the show configuration pending command in any command mode.
Note Committing multiple commands together is not an atomic operation. If any command fails, the successful commands are applied despite the failure. Failed commands are reported in an error message.
Command Output Formats
Most CLI show commands accept an optional detail keyword that causes the output information to be displayed as a list rather than a table. You can configure either of two presentation formats for displaying the output information when the detail keyword is used. The format choices are as follows:
• Default—For easy viewing, the command output is presented in a compact list.
This example shows command output in the default format:
Server /chassis # set cli output default
Server /chassis # show hdd detail
Name HDD_01_STATUS:
Status : present
|

Overview
Online Help for the CLI
Name HDD_02_STATUS:
Status : present
Name HDD_03_STATUS:
Status : present
Name HDD_04_STATUS:
Status : present
Server /chassis #
•YAML—For easy parsing by scripts, the command output is presented in the YAML (YAML Ain't Markup Language) data serialization language, delimited by defined character strings.
This example shows command output in the YAML format:
Server /chassis # set cli output yaml
Server /chassis # show hdd detail
---
name: HDD_01_STATUS hdd-status: present
---
name: HDD_02_STATUS hdd-status: present
---
name: HDD_03_STATUS hdd-status: present
---
name: HDD_04_STATUS hdd-status: present
...
Server /chassis #
For detailed information about YAML, see http://www.yaml.org/about.html.
In most CLI command modes, you can enter set cli output default to configure the default format, or set cli output yaml to configure the YAML format.
Online Help for the CLI
At any time, you can type the ? character to display the options available at the current state of the command syntax.
If you have not typed anything at the prompt, typing ? lists all available commands for the mode you are in. If you have partially typed a command, typing ? lists all available keywords and arguments available at your current position in the command syntax.

Installing the Server OS
This chapter includes the following sections:
• OS Installation Methods, page 11
• KVM Console, page 11
• PXE Installation Servers, page 12
OS Installation Methods
C-Series servers support several operating systems. Regardless of the OS being installed, you can install it on your server using one of the following tools:
•KVM console
•PXE installation server
KVM Console
The KVM console is an interface accessible from CIMC that emulates a direct keyboard, video, and mouse (KVM) connection to the server. The KVM console allows you to connect to the server from a remote location.
Instead of using CD/DVD or floppy drives physically connected to the server, the KVM console uses virtual media, which are actual disk drives or disk image files that are mapped to virtual CD/DVD or floppy drives. You can map any of the following to a virtual drive:
•CD/DVD or floppy drive on your computer
•Disk image files (ISO or IMG files) on your computer
•USB flash drive on your computer
•CD/DVD or floppy drive on the network
•Disk image files (ISO or IMG files) on the network
•USB flash drive on the network

Installing the Server OS
PXE Installation Servers
You can use the KVM console to install an OS on the server.
PXE Installation Servers
A Preboot Execution Environment (PXE) installation server allows a client to boot and install an OS from a remote location. To use this method, a PXE environment must be configured and available on your VLAN, typically a dedicated provisioning VLAN. Additionally, the server must be set to boot from the network.
When the server boots, it sends a PXE request across the network. The PXE installation server acknowledges the request, and starts a sequence of events that installs the OS on the server.
PXE servers can use installation disks, disk images, or scripts to install an OS. Proprietary disk images can also be used to install an OS, additional components, or applications.
Note PXE installation is an efficient method for installing an OS on a large number of servers. However, considering that this method requires setting up a PXE environment, it might be easier to use another installation method.
Installing an OS Using a PXE Installation Server
Before You Begin
•Verify that the server can be reached over a VLAN.
•You must log in as a user with admin privileges to install an OS.
Procedure
Step 1 Set the boot order to PXE first.
Step 2 Reboot the server.
If a PXE install server is available on the VLAN, the installation process begins when the server reboots. PXE installations are typically automated and require no additional user input. Refer to the installation guide for the OS being installed to guide you through the rest of the installation process.
What to Do Next
After the OS installation is complete, reset the LAN boot order to its original setting.

Managing the Server Boot Order
Server Boot Order
Using CIMC, you can configure the order in which the server attempts to boot from available boot device types.
When you change the boot order configuration, CIMC sends the configured boot order to the BIOS the next time the server is rebooted. To implement the new boot order, reboot the server after making the configuration change. The new boot order will take effect on any subsequent reboot. The configured boot order is not sent again until the configuration is changed again.
