NOTE: Some configuration files contain unique CMC information (such as the static IP address) that must be modified before you export the file to other CMCs. 1. Use RACADM to query the target CMC that contains the desired configuration. NOTE: The generated configuration file is myfile.cfg. You can rename the file. The .cfg file does not contain user passwords. When the .cfg file is uploaded to the new CMC, you must re-add all passwords. 2.
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. Over time, the group may become fragmented with used and unused indexes. If an index is present, it is modified. If an index is not present, the first available index is used.
Any character to the right of the = (for example, a second =, a #, [, ], and so on) is taken as-is. These characters are valid modem chat script characters. [cfgLanNetworking] -{group name} cfgNicIpAddress=143.154.133.121 {object value} • The .cfg parser ignores an index object entry. You cannot specify which index is used. If the index already exists, it is either used or the new entry is created in the first available index for that group. The racadm getconfig -f .
This file is updated as follows: # # Object Group "cfgLanNetworking" # [cfgLanNetworking] cfgNicIpAddress=10.35.9.143 # comment, the rest of this line is ignored cfgNicGateway=10.35.9.1 The command racadm config -f .cfg parses the file and identifies any errors by line number. A correct file updates the proper entries. Additionally, you can use the same getconfig command from the previous example to confirm the update.
Configuring Servers 7 You can configure the following settings of a server: • Slot Names • iDRAC Network Settings • DRAC VLAN Tag Settings • First Boot Device • Server FlexAddress • Remote File Share • BIOS Settings Using Server Clone Configuring Slot Names Slot names are used to identify individual servers.

If you are not sure about the index number, run the following command: racadm getconfig -g cfgTraps -i Configuring E-Mail Alert Settings When CMC detects a chassis event, such as an environmental warning or a component failure, it can be configured to send an e-mail alert to one or more e-mail addresses.
where is a value between 1–4. CMC uses the index number to distinguish up to four destination email addresses that can be configured. 5. Specify a destination email address to receive the email alerts: racadm config -g cfgEmailAlert -o cfgEmailAlertAddress -i where is a valid email address, and is the index value you specified in step 4. 6.
Configuring User Accounts and Privileges 9 You can setup user accounts with specific privileges (role-based authority) to manage your system with CMC and maintain system security. By default, CMC is configured with a local administrator account. The default user name is rootand the password is calvin. As an administrator, you can set up user accounts to allow other users to access the CMC.
Privilege Description themselves. For this reason, slot names and slot priorities can be added or changed whether or not servers are present in the slots. When a server is moved to a different chassis, it inherits the slot name and priority assigned to the slot it occupies in the new chassis. The previous slot name and priority remain with the previous chassis. NOTE: CMC users with the Chassis Configuration Administrator privilege can configure power settings.
Privilege Description chassis user does not have the Server Administrative privilege on the chassis. Server Configuration Administrator: • • • • Set IP address Set gateway Set subnet mask Set first boot device Configure Users: • • Set iDRAC root password iDRAC reset Server Control Administrator: • • • • • Power on Power off Power cycle Graceful shutdown Server Reboot Test Alert User User can send test alert messages. Debug Command Administrator User can execute system diagnostic commands.

Modifying Root User Administrator Account Settings For added security, it is strongly recommended that you change the default password of the root (User 1) account. The root account is the default administrative account that is shipped with CMC. To change the default password for the root account: 1. In the left pane, click Chassis Overview, and then click User Authentication. 2. On the Users page, in the User ID column, click 1.
To verify if a user exists, open a Telnet/SSH text console to the CMC, log in, and then type the following command once for each index of 1–16: racadm getconfig -g cfgUserAdmin -i NOTE: You can also type racadm getconfig -f and view or edit the myfile.cfg file, which includes all the CMC configuration parameters. Several parameters and object IDs are displayed with their current values.
Disabling CMC User When using RACADM, users must be disabled manually on an individual-basis. Users cannot be deleted using a configuration file. To delete a CMC user, the command syntax is: racadm config -g cfgUserAdmin -o cfgUserAdminUserName -i "" racadm config -g cfgUserAdmin -i 2 -o cfgUserAdminPrivilege 0x0 A null string of double quotation marks ("") instructs CMC to remove the user configuration at the specified index, and then reset the user configuration to the factory default values.
Standard Schema Active Directory Overview As shown in the following figure, using standard schema for Active Directory integration requires configuration on both Active Directory and CMC. 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.
Configuring Standard Schema Active Directory To configure CMC for an Active Directory login access: 1. On an Active Directory server (domain controller), open Active Directory Users and Computers Snap-in. 2. Using the CMC Web interface or RACADM: a) Create a group or select an existing group. b) Configure the role privileges. 3. Add the Active Directory user as a member of the Active Directory group to access CMC.
Configuring Active Directory With Standard Schema Using RACADM At the RACADM command prompt, run the following commands: – Using config command: racadm config -g cfgActiveDirectory -o cfgADEnable 1 racadm config -g cfgActiveDirectory -o cfgADType 2 racadm config -g cfgStandardSchema -i -o cfgSSADRoleGroupName racadm config -g cfgStandardSchema -i -o cfgSSADRoleGroupDomain racadm config -g cfgStandardSchema -i -o cfgSSADRo
NOTE: If certificate validation is enabled, specify the Domain Controller Server addresses and the Global Catalog FQDN. Make sure that DNS is correctly configured. Extended Schema Active Directory Overview Using the extended schema solution requires the Active Directory schema extension. Active Directory Schema Extensions The Active Directory data is a distributed database of attributes and classes.
Additionally, you can configure Active Directory objects in a single domain or in multiple domains. For example, you have two CMCs (RAC1 and RAC2) and three existing Active Directory users (user1, user2, and user3). You want to give user1 and user2 an administrator privilege to both CMCs and give user3 a login privilege to the RAC2 card. When adding Universal Groups from separate domains, create an Association Object with Universal Scope.

Configuring CMC For Single Sign-On Or Smart Card Login 10 This section provides information to configure CMC for Smart Card login and Single Sign-On (SSO) login for Active Directory users. SSO uses Kerberos as an authentication method allowing users, who have signed in as an automatic- or single sign-on to subsequent applications such as Exchange.
CMC • Each CMC must have an Active Directory account. • CMC must be a part of the Active Directory domain and Kerberos Realm. Prerequisites For Single Sign-On Or Smart Card Login The pre-requisites to configure SSO or Smart Card logins are: • Setup the kerberos realm and Key Distribution Center (KDC) for Active Directory (ksetup). • A robust NTP and DNS infrastructure to avoid issues with clock drift and reverse lookup.
For information about configuring CMC for Extended Schema Active Directory, see Extended Schema Active Directory Overview. Configuring Browser For SSO Login Single Sign-On (SSO) is supported on Internet Explorer versions 6.0 and later, and Firefox versions 3.0 and later. NOTE: The following instructions are applicable only if CMC uses Single Sign-On with Kerberos authentication. Internet Explorer To configure Internet Explorer for Single Sign-On: 1.
NOTE: For information about the options, see the Online Help. 1. While configuring Active Directory to setup a user account, perform the following additional steps: – Upload the keytab file. – To enable SSO, select the Enable Single Sign-On option. – To enable smart card login, select the Enable Smart-Card Login option. NOTE: If these two options are selected, all command line out-of-band interfaces, including secure shell (SSH), Telnet, Serial, and remote RACADM remain unchanged . 2. Click Apply.
11 Configuring CMC to Use Command Line Consoles This section provides information about the CMC command line console (or serial/Telnet/Secure Shell console) features, and explains how to set up the system so that you can perform systems management actions through the console. For information about using the RACADM commands in CMC through the command line console, see Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide.

Using FlexAddress and FlexAdress Plus Cards 12 This section provides information about FlexAddress, FlexAddress Plus Cards, and configuring and using these the cards. NOTE: The FlexAddress feature is licensed, and you must an Enterprise License to use this. About FlexAddress The FlexAddress feature is an optional upgrade that allows server modules to replace the factory-assigned World Wide Name and Media Access Control (WWN/MAC) network IDs with WWN/MAC IDs provided by the chassis.
chassis to assign World Wide Name/Media Access Control (WWN/MAC) addresses to Fibre Channel and Ethernet devices. Chassis assigned WWN/MAC addresses are globally unique and specific to a server slot. Activating FlexAddress FlexAddress is delivered on a Secure Digital (SD) card that must be inserted into CMC to activate the feature. To activate a FlexAddress feature, software updates may be required. If you are not activating FlexAddress, these updates are not required.
about making a redundant CMC active, see the Chassis Management Controller (CMC) Secure Digital (SD) Card Technical Specification document. When CMC restarts, verify the activation process. For more information about activating FlexAddress, see Verifying Flexddress Activation. Activating FlexAddress Plus FlexAddress Plus is delivered on the FlexAddress Plus Secure Digital (SD) card along with the FlexAddress feature.
The command returns the following status message: Feature = FlexAddress Date Activated = 8 April 2008 - 10:39:40 Feature installed from SD-card SN = 01122334455 If there are no active features on the chassis, the command returns a message: racadm feature -s No features active on the chassis Dell Feature Cards may contain more than one feature.
Viewing FlexAddress Information For Chassis FlexAddress status information can be displayed for the entire chassis. The status information includes whether the feature is active and an overview of the FlexAddress status for each server. To view the chassis FlexAddress status using the CMC web interface, click Chassis Overview → Setup . The General Chassis Settings page is displayed. The FlexAddress has a value Active or Not Active.
Viewing FlexAddress Information for Individual Servers To view FlexAddress information for a particular server using the CMC Web interface: 1. In the left pane, expand Server Overview. All the servers inserted in the chassis are listed. 2. Click the server you want to view. The Server Status page is displayed. 3. Click the Setup tab, and then click FlexAddress. The FlexAddress page is displayed that provides the WWN configuration and MAC addresses for the selected server.
Configuring FlexAddress for Chassis-Level Fabric and Slots At the chassis level, you can enable or disable the FlexAddress feature for fabrics and slots. FlexAddress is enabled on a per-fabric–basis and then slots are selected for participation in the feature. Both fabrics and slots must be enabled to successfully configure FlexAddress.
Viewing World Wide Name/Media Access Control (WWN/MAC) IDs The WWN/MAC Summary page allows you to view the WWN configuration and MAC address of a slot in the chassis. Fabric Configuration The Fabric Configuration section displays the type of Input/Output fabric that is installed for Fabric A. A green check mark indicates that the fabric is enabled for FlexAddress.

Dell warrants that the Software disks is free from defects in materials and workmanship under normal use for ninety (90) days from the date you receive them. This warranty is limited to you and is not transferable. Any implied warranties are limited to ninety (90) days from the date you receive the Software. Some jurisdictions do not allow limits on the duration of an implied warranty, so this limitation may not apply to you.
Managing Fabrics 13 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 You can specify the network settings for the interface used to manage the IOM. For Ethernet switches, the out-of-band management port (IP address) is configured. The in-band management port (that is, VLAN1) is not configured using this interface. Before configuring the network settings for the IOM, make sure the IOM is turned on. To configure the network setting of IOM in Group A, you must have the Fabric A Administrator privileges.
Managing and Monitoring Power 14 The Dell PowerEdge VRTX chassis is the most power-efficient modular server enclosure. It is designed to include highlyefficient 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.
AC Redundancy Policy The purpose of the AC redundancy policy is to enable a modular enclosure system to operate in a mode in which it can tolerate AC power failures. These failures may originate in the AC power grid, the cabling and delivery, or a PSU itself. When you configure a system for AC redundancy, the PSUs are divided into grids: PSUs in slots 1 and 2 are in the first grid while PSUs in slots 3 and 4 are in the second grid.
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.
CAUTION: In AC redundancy mode, you must have balanced sets of PSUs (at least one PSU in each grid). If this condition is not met, AC redundancy is not possible. Power Supply Redundancy When power supply redundancy is enabled, a PSU in the chassis is kept as a spare, ensuring that the failure of any one PSU does not cause the servers or chassis to turn off. Power supply redundancy mode requires minimum two PSUs.
priority servers may get less power than priority-one servers based on System Input Max Power Capacity, and the userconfigured setting of System Input Power Cap. Configuration changes, such as an additional server, shared HDDs, or PCIe cards in the chassis, may require the System Input Power Cap to be increased. Power needs in a modular enclosure also increase when thermal conditions change and the fans are required to run at higher speed, which causes them to consume additional power.
Assigning Priority Levels To Servers Using CMC Web Interface To assign priority levels: 1. In the left pane, click Server Overview → Power → Priority . The Server Priority page lists all the servers in the chassis. 2. From the Priority drop-down menu, select a priority level (1–9, where 1 is the highest priority) for one, multiple, or all servers. The default value is 1. You can assign the same priority level to multiple servers. 3. Click Apply to save your changes.
Viewing Power Budget Status Using RACADM Open a serial/Telnet/SSH text console to CMC, log in, and type: racadm getpbinfo For more information about getpbinfo, including output details, see the getpbinfo command section in the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. Redundancy Status and Overall Power Health The redundancy status is a factor in determining the overall power health.
This occurs if the administrator had configured power limit for the chassis lower than the full power allocation to the servers or if insufficient power is available to servers requiring high power. The following table provides the actions taken by CMC, when a new server is powered on in the scenario described earlier. Table 29.
AC input received The power input for power supply is lost. AC input lost The power input for power supply has been restored. DC output produced Power supply is operating normally. DC output lost Power supply failed. Events related to changes in the power redundancy status that record entries in the SEL are redundancy loss and redundancy regain for the modular enclosure that is configured for either an AC Redundancy power policy or Power Supply Redundancy power policy.
Maximum Power Conservation Mode This is enabled only when AC redundancy is selected. CMC performs maximum power conservation when: • Maximum conservation mode is enabled • An automated command line script, issued by a UPS device, enables maximum conservation mode. In maximum power conservation mode, all servers start functioning at their minimum power levels, and all subsequent server power allocation requests are denied. In this mode, the performance of powered on servers may be degraded.
• Redundancy policy • Remote power logging • Server performance over power redundancy • Dynamic power supply engagement • Server power of 11th generation and earlier servers OPMC then manages prioritization and power of 12th generation server nodes in the chassis from the budget available after allocation of power to chassis infrastructure and prior generation server nodes. Remote power logging is unaffected by external power management.
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 0 (AC Redundancy), and 1 (Power Supply Redundancy). The default value is 0.
– To enable remote power management by Open Manage Power Center (OPMC), type: racadm config -g cfgChassisPower -o cfgChassisServerBasedPowerMgmtMode 1 – To restore CMC power management, type: racadm config -g cfgChassisPower -o cfgChassisServerBasedPowerMgmtMode 0 For information about RACADM commands for chassis power, see the config, getconfig, getpbinfo, and cfgChassisPower sections in the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide.
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: To perform power management actions, you must have the Chassis Configuration Administrator privilege. Executing Power Control Operations for Multiple Servers Using CMC Web Interface To execute power control operation for multiple servers using the Web interface: 1. In the left pane, click Server Overview → Power.
Executing Power Control Operations on the IOM Using RACADM To execute power control operations on the IOM using RACADM, open a serial/Telnet/SSH text console to CMC, log in, and type: racadm chassisaction -m switch where indicates the operation you want to execute: power cycle.
Managing Chassis Storage 15 On the Dell PowerEdge VRTX, you can perform the following operations: • View the status of physical disks drives and storage controllers. • View the properties of controllers, physical disk drives, virtual disks, and enclosures. • Set up controllers, physical disk drives, and virtual disks. • Assign virtual adapters. • Troubleshoot controller, physical disk drives, and virtual disks. • Update storage components.
• Virtual disks are created and they are assigned as Virtual Adapter 1, Virtual Adapter 2, Virtual Adapter 3, or Virtual Adapter 4. For more information, see Applying Virtual Adapter Access Policy to Virtual Disks. NOTE: You can map only one virtual adapter to one server at a time. Without an appropriate license, you can map the VA to the default server, or unmap a VA–server assignment. The default mapping is VA1–Server Slot 1, VA2– Server Slot 2, VA3–Server Slot 3, and VA4–Server Slot 4.
– Under the Basic Physical Disks Filter option , from the Group By drop-down menu, select Virtual Disk, Controller, or Enclosure, and then click Apply. – Click Advanced Filter, select the values for various attributes, and then click Apply.
Viewing Virtual Disk Properties Using RACADM To view virtual disk properties using RACADM, run the command racadm raid get vdisks -o For more information, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. Creating Virtual Disk Using CMC Web Interface Make sure that the physical disk is installed in the chassis. NOTE: Deleting a virtual disk removes the virtual disk from the controller's configuration. To create a virtual disk: 1.
NOTE: If you select Delete, the following message is shown indicating that deleting a virtual disk will permanently delete data available in that virtual disk. Deleting the virtual disk removes the virtual disk from the controller's configuration. Initializing the virtual disk permanently erases data from the virtual disk.
Managing PCIe Slots 16 By default, all slots are unmapped. You can do the following: • View the status of all PCIe Slots in the chassis. • Assign or unassign a PCIe slot to the servers. Consider the following before assigning a PCIe slot to a server: • An empty PCIe slot cannot be assigned to a server that is turned on. • A PCIe slot with an adapter assigned to a server cannot be assigned to another server if the currently-assigned server (source) is turned on.
Managing PCIe Slots Using RACADM You can assign or unassign a PCIe slot to a server by using the RACADM commands. Some of the commands are given here. 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.

chassis to maintain AC redundancy. (For full AC Redundancy operation, make sure that a full PSU configuration of four power supplies is available.) – • • • • Problem: The PSU state is displayed as Failed (No AC), even when an AC cord is connected and the power distribution unit is producing good AC output. – Resolution A: Check and replace the AC cord. Check and confirm that the power distribution unit providing power to the power supply is operating as expected.
• Problem: Overall server performance decreases when the ambient temperature increases in the data center. – Resolution: This can occur if the System Input Power Cap has been configured to a value that results in an increased power need by fans having to be made up by reduction in the power allocation to the servers. User can increase the System Input Power Cap to a higher value that allow for additional power allocation to the fans without an impact on server performance.
NOTE: CMC creates a new log entry indicating that the log was cleared. NOTE: To clear the hardware log, you must have the Clear Logs Administrator privilege. Viewing Hardware Logs Using RACADM To view the hardware log using RACADM, open a serial/Telnet/SSH text console to CMC, log in, and type: racadm getsel To clear the hardware log, type: racadm clrsel Viewing Chassis Log CMC generates a log of the chassis-related events.
Resetting Components You can reset the active CMC, or to virtually reset servers making them to behave as if they were removed and reinserted. If the chassis has a standby CMC, resetting the active CMC causes a failover and the standby CMC becomes active. NOTE: To reset components, you must have Debug Command Administrator privilege. To reset the components using the CMC Web interface, 1. In the left pane, click Chassis Overview → Troubleshooting → Reset Components. The Reset Components page is displayed.
You can also check the ntpd status by typing the following racadm command: racadm getractime –n If the ‘*’ is not displayed for one of the configured servers, the settings may not be configured correctly. The output of this command contains detailed NTP statistics that may be useful in debugging the problem. If you attempt to configure a Windows-based NTP server, it may help to increase the MaxDist parameter for ntpd.

Frequently Asked Questions 19 This section lists the frequently asked questions about the following: • RACADM • Managing and Recovering a Remote System • Active Directory • FlexAddress and FlexAddressPlus • iKVM RACADM After performing a CMC reset (using the RACADM racreset subcommand), when a command is entered, the following message is displayed: racadm Transport: ERROR: (RC=-1) What does this message mean? Another command must be issued only after CMC completes the reset.
CMC includes a default CMC server certificate to ensure network security for the web interface and remote RACADM features. When this certificate is used, the web browser displays a security warning because the default certificate is issued to CMC default certificate which does not match the host name of CMC (for example, the IP address). To address this security concern, upload a CMC server certificate issued to the IP address of CMC.
Active Directory Does Active Directory support CMC login across multiple trees? Yes. The CMC’s Active Directory querying algorithm supports multiple trees in a single forest. Does the login to CMC using Active Directory work in mixed mode (that is, the domain controllers in the forest run different operating systems, such as Microsoft Windows 2000 or Windows Server 2003)? Yes.
No activation or modifications to the card should occur. The card is ignored by CMC.
If the CMC subsequently becomes active, with the FlexAddressPlus feature card still in the card slot, the FlexAddressPlus feature gets reactivated, and slot or fabric flexaddress configuration changes can resume. IOM After a configuration change, sometimes CMC displays the IP address as 0.0.0.0. Click the Refresh icon to see if the IP address is set correctly on the switch. If an error is made in setting the IP/mask/ gateway, the switch does not set the IP address and returns a 0.0.0.0 in all fields.
