2 Installing and Setting Up CMC This section provides information about how to install your CMC hardware, establish access to CMC, configure your management environment to use CMC, and guides you through the tasks for configuring a CMC: • • • • Set up initial access to CMC. Access CMC through a network. Add and configure CMC users. Update CMC firmware. For more information about installing and setting up redundant CMC environments, see Understanding Redundant CMC Environment.
6. Using the LCD panel, navigate to the IP Summary and click on the Check button to select. Use the IP address for the CMC in the management system browser (IE, Chrome, or Mozilla). To set up DHCP for CMC, use LCD panel to, click Main Menu > Settings > Network Settings. 7. Connect to the CMC IP address by using a web browser by typing the default username (root) and password (calvin). 8. Provide each iDRAC with an IP address in the CMC web interface, and enable the LAN and IPMI interface.
NOTE: When using the RACADM remote capability, you must have the 'write' permission on the folders where you are using the RACADM subcommands, involving the file operations. For example, racadm getconfig -f . Uninstalling RACADM From a Linux Management Station 1. Log in as root to the system where you want to uninstall the management station features. 2. Run the following rpm query command to determine which version of the DRAC tools is installed: rpm -qa | grep mgmtst-racadm 3.
Microsoft Phishing Filter If the Microsoft Phishing Filter is enabled in Internet Explorer on your management system, and your CMC does not have Internet access, accessing CMC may be delayed by a few seconds. This delay can happen if you are using the browser or another interface such as remote RACADM. To disable the phishing filter: 1. Start Internet Explorer. 2. Click Tools > Phishing Filter, and then click Phishing Filter Settings. 3. Select the Disable Phishing Filter option and click OK.
iDRAC communication delays. These delays may cause unpredictable chassis behavior, such as CMC displaying iDRAC as offline even when it is up and running, which in turn causes other unwanted behavior. If physically isolating the management network is impractical, the other option is to separate CMC and iDRAC traffic to a separate VLAN. CMC and individual iDRAC network interfaces can be configured to use a VLAN.
3. If you are asked to select an appropriate network speed, select a network speed (Auto (1Gb), 10Mb, or 100Mb) using appropriate buttons. For effective network throughput, the network speed setting must match your network configuration. Setting the network speed lower than the speed of your network configuration increases bandwidth consumption and slows down the network communication. Determine whether or not your network supports the above network speeds and set it accordingly.
Table 9. Network mode (continued) Network mode Description If you have selected the Static option, press the center button, and then do the following: a. The following message asks you whether or not you want to automatically increment by using the IP of Slot–1. IPs will auto-increment by slot number. Click the center button.

Table 10. CMC Interfaces Interface Description Web interface Provides remote access to CMC using a graphical user interface. The Web interface is built into the CMC firmware and is accessed through the NIC interface from a supported web browser on the management station. For a list of supported Web browsers, see the “Supported Browsers” section in the Dell System Software Support Matrix at dell.com/support/manuals.
Table 10. CMC Interfaces (continued) Interface Description WinRM tool sets a default response timeout of 60 seconds for all WSMan commands it sends out. WinRM does not allow varying this timeout interval. Using “winrm set winrm/config @{MaxTimeoutms ="80000"}” does not change the timeout due to a bug in the WinRM tool. Therefore, it is recommended that WinRM is not used for commands that may take more than one minute to complete execution.
Setting Chassis Physical Location and Chassis Name Using RACADM To set the chassis name, location, date, and time by using the command line interface, see the setsysinfo and setchassisname commands. For more information, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. Setting Date and Time on CMC You can manually set the date and time, or you can synchronize the date and time with a Network Time Protocol (NTP) server.
Configuring LED Blinking Using RACADM Open a serial/Telnet/SSH text console to CMC, log in, and type: racadm setled -m [-l ], where specifies the module whose LED you want to configure. Configuration options: • • • server-n where n = 1-4 switch-1 cmc-active and specifies whether or not the LED should blink.

CMC. When both CMCs are updated, you can use the cmcchangeover command to restore the CMCs to their previous roles. CMC firmware revision 2.x updates both the primary CMC and the redundant CMC without running the cmcchangeover command. During the final phases of the firmware update process in CMC, the browser session and connection with CMC is lost temporarily as the CMC is not connected to the network. CMC generates the chassis overall health as critical owing to the temporary network loss.
If the processes are not followed in order, system behavior becomes random and parts of the system may become unstable. The CMC logs IOV or RAID controller messages. Only shared storage VA mappings for PERC 1 and PERC 2 are visible in the older version of CMC. All external shared storage VA mappings do not exist in the previous version of the CMC. If an External Shared PERC 8 card is inserted after the rollback, the CMC treats it as a non-shared adapter.

On the System Setup Main Menu page, go to iDRAC Settings > Lifecycle Controller, click Enabled. Go to the System Setup Main Menu page and click Finish to save the settings.
• Sometimes, a BIOS firmware update image may be compatible across a number of server models. Such optimizations are ignored in case this compatibility is no longer true in the future. Automatic filtering is important for firmware updates of Network Interface Controllers (NIC) and RAID Controllers. These device categories have different types and models.
• • If the server is listed as Not Ready, it indicates that when the firmware inventory was retrieved, the iDRAC on the server was still initializing. Wait for the iDRAC to be fully operational, and then refresh the page to retrieve the firmware inventory again. If the inventory of components and devices does not reflect what is physically installed on the server, invoke the Lifecycle Controller when the server is in the boot process.
2. Click Save Inventory Report. The Inventory.xml file is saved on an external system. NOTE: The Dell Repository Manager Application uses the Inventory.xml file as an input to create a repository of updates for all the blades available in the chassis. This repository can be later exported to a network share. Update from Network Share mode of firmware update uses this network share to update the components of all the servers.
Only one type of operation can be performed at a time. Components and devices that are not supported may be listed as part of the inventory, but do not permit Lifecycle Controller operations. To perform the Lifecycle Controller operations, you must have: • • For CMC: Server Administrator privilege. For iDRAC: Configure iDRAC privilege and Log in to iDRAC privilege. A Lifecycle Controller operation scheduled on a server may take 10 to 15 minutes to complete.
Upgrading Server Component Firmware You can install the next version of the firmware image for selected components or devices across one or more servers. The firmware image is available within the Lifecycle Controller for a rollback operation. To use this feature, you must have an Enterprise License.

NOTE: If the backup files (.bak) of the earlier versions of CMC, are loaded on the latest version of CMC where FIPS is enabled, reconfigure all the 16 CMC local user passwords. However, the password of the first user is reset to "calvin". NOTE: When a chassis configuration profile is imported from a CMC, which does not support the FIPS feature, to a CMC where FIPS is enabled, the FIPS remains enabled in the CMC.
2. Click OK to delete the selected profile. Configuring Multiple CMCs Using RACADM Using RACADM, you can configure one or more CMCs with identical properties. When you query a specific CMC card using its group ID and object ID, RACADM creates the racadm.cfg configuration file from the retrieved information. By exporting the file to one or more CMCs, you can configure your controllers with identical properties in a minimal amount of time.
Follow these guidelines when you create a .cfg file: • If the parser encounters an indexed group, it is the value of the anchored object that differentiates the various indexes. • The parser reads in all of the indexes from the CMC for that group. Any objects within that group are modifications when the CMC is configured. If a modified object represents a new index, the index is created on the CMC during configuration. You cannot specify a desired index in a .cfg file. Indexes may be created and deleted.
NOTE: You may create an indexed group manually using the following command: racadm config -g • -o -i The line for an indexed group cannot be deleted from a .cfg file. If you do delete the line with a text editor, RACADM stops when it parses the configuration file and alert you of the error.
NOTE: Anchor is a reserved word and should not be used in the .cfg file.

Configure Local Users Using RACADM NOTE: You must be logged in as a root user to execute RACADM commands on a remote Linux system. You can configure up to 16 users in the CMC property database. Before you manually enable a CMC user, verify if any current users exist. If you are configuring a new CMC or if you have used the racadm racresetcfg command, the only current user is root with the password calvin. The racresetcfg subcommand resets all configuration parameters to the default values.
For more information about the RACADM commands, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide available at dell.com/support/manuals. Disabling CMC User When using RACADM, users must be disabled manually on an individual-basis. Users cannot be deleted using a configuration file.
In Active Directory, a standard group object is used as a role group. A user who has CMC access is a member of the role group. To give this user access to a specific CMC card, the role group name and its domain name need to be configured on the specific CMC card. The role and the privilege level is defined on each CMC card and not in the Active Directory. You can configure up to five role groups in each CMC. The following table shows the default role group privileges. Table 23.
• ○ User Domain from Login — to perform the DNS lookup with the domain name of the login user. ○ Specify a Domain — enter the domain name to use for the DNS lookup To enable CMC to use the specified Active Directory Domain Controller server addresses, select Specify Domain Controller Addresses . These server addresses are the addresses of the domain controllers where the user accounts and the role groups are located. 4. Click Apply to save the settings. NOTE: You must apply the settings before continuing.
At least one of the three addresses is required to be configured. CMC attempts to connect to each of the configured addresses one-by-one until it makes a successful connection. With Standard Schema, these are the addresses of the domain controllers where the user accounts and the role groups are located.

13 Managing Fabrics The chassis supports a fabric type, which is Fabric A. Fabric A is used by the single I/O Module, and is always connected to the on-board Ethernet adapters of the servers. The chassis has only one I/O module (IOM), where the IOM is a pass-through or switch module. The I/O Module is classified as group A. Chassis IOM uses a discrete data path called Fabric, and it is named A. The Fabric A supports only Ethernet.
Configuring Network Settings for IOM Using CMC Web Interface To configure the network settings for I/O Module: 1. In the left pane, click Chassis Overview, click I/O Module Overview, and then click Setup. Alternatively, to configure the network settings of the only available I/O module that is A, click A Gigabit Ethernet, and then click Setup.

14 Managing and Monitoring Power The PowerEdge VRTX chassis is the most power-efficient modular server enclosure. It is designed to include highly efficient power supplies and fans, has an optimized layout for the air to flow more easily through the system, and contains power-optimized components throughout the enclosure.
Redundancy Policies Redundancy policy is a configurable set of properties that determine how CMC manages power to the chassis. The following redundancy policies are configurable with or without dynamic PSU engagement: • • Grid redundancy Power supply redundancy Grid Redundancy Policy The purpose of the Grid redundancy policy is to enable a modular enclosure system to operate in a mode in which it can tolerate AC power failures.
To operate remaining PSUs at their maximum efficiency, use the following power redundancy modes: • • • PSU Redundancy mode with DPSE provides power efficiency. At least two supplies are online, with one PSU required to power the configuration, and one to provide redundancy in case of a PSU failure. PSU Redundancy mode offers protection against the failure of any one PSU, but offers no protection in the event of an AC grid loss.
Power Budgeting For Hardware Modules CMC offers a power budgeting service that allows you to configure power budget, redundancy, and dynamic power for the chassis. The power management service enables optimization of power consumption and reallocation of power to different modules on the basis of demand. CMC maintains a power budget for the enclosure that reserves the necessary wattage for all installed servers and components. CMC allocates power to the CMC infrastructure and the servers in the chassis.
According to the default server slot priority setting, power is equally apportioned to all slots. Changing the slot priorities allows administrators to prioritize the servers that are given preference for power allocations. If the more critical server modules are left at their default slot priority of 1, and the less critical server modules are changed to lower priority value of 2 or higher, the priority 1 server modules is powered on first.
Viewing Power Consumption Status Using CMC Web Interface In the left pane, click Chassis Overview > Power > Power Monitoring. The Power Monitoring page displays the power health, system power status, real-time power statistics, and real-time energy statistics. For more information, see the Online Help. NOTE: You can also view the power redundancy status under Power Supplies.
wait for eight-and-a-half minutes to determine if redundancy exists. Ensure that the redundancy state is healthy before initiating any failover owing to the health changes. NOTE: CMC does not perform a pre-check of these conditions when you change the redundancy policy to or from Grid redundancy. So, configuring the redundancy policy may immediately result in redundancy lost or a regained condition.
Table 39. Chassis Impact from PSU Failure or Removal PSU Configuration Dynamic PSU Engagement Firmware Response Grid Redundancy Disabled CMC alerts you about loss of Grid redundancy. Power Supply Redundancy Disabled CMC alerts you about loss of power supply redundancy. Grid Redundancy Enabled CMC alerts you about loss of Grid Redundancy. PSUs in standby mode (if any) are turned on to compensate for power budget lost from the PSU failure or removal.
• • • Remote Power Logging Interval Server Based Power Management Disable AC Power Recovery Power Conservation and Power Budget CMC conserves power when the user-configured maximum power limit is reached. When the demand for power exceeds the user configured System Input Power Cap, CMC reduces power to servers in reverse-priority order to free power for higher priority servers and other modules in the chassis.
External Power Management CMC power management is optionally controlled by the OpenManage Power Center (OMPC). For more information, see the OMPC User’s Guide.
To enable and set the redundancy policy: 1. Open a serial/Telnet/SSH text console to CMC and log in. 2. Set properties as needed: • To select a redundancy policy, type: racadm config -g cfgChassisPower -o cfgChassisRedundancyPolicy where is 1 (Grid Redundancy), and 2 (Power Supply Redundancy). The default value is 2.
• To determine the power remote logging interval, enter the following command: racadm getconfig -g cfgRemoteHosts -o cfgRhostsSyslogPowerLoggingInterval • The power remote logging feature is dependent on previously configured remote syslog hosts having been . Logging to one or more remote syslog hosts must be enabled, otherwise power consumption is logged. This can be done either through the web GUI or the RACADM CLI. For more information, see the remote syslog configuration instructions.
Executing Power Control Operations on the Chassis Using RACADM Open a serial/Telnet/SSH text console to CMC, log in, and type: racadm chassisaction -m chassis where is powerup, powerdown, powercycle, nongraceshutdown, or reset. Executing Power Control Operations on a Server You can remotely perform power management actions for multiple servers at a time or an individual server in the chassis. NOTE: The modular blade servers are in throttle state during CMC reboot or failover.
