To edit a slot name using the CMC Web interface: 1. In the left pane, go to Chassis Overview → Server Overview → Setup → Slot Names. 2. On the Slot Names page, edit the slot name, in the Slot Name field. 3. To use a server’s host name as slot name, select the Use Host Name for the Slot name option. This overrides the static slot names with the server’s Host Name (or system name), if available. This requires the OMSA agent to be installed on the server.
Setting Description selected, this password value is assigned to a server's iDRAC root user password when the server is inserted into a chassis. The password can have 1 to 20 printable (including white spaces) characters. Confirm iDRAC Root Password Allows you to retype the password provided in the Password field. Enable iDRAC LAN Enables or disables the iDRAC LAN channel. By default, this option is cleared. Enable iDRAC IPv4 Enables or disables IPv4 on iDRAC. By default, this option is selected.
3. Setting Description iDRAC IPv4 Gateway Specifies the QuickDeploy default gateway that is assigned to all the DRAC present in the chassis. Enable iDRAC IPv6 Enables IPv6 addressing for each iDRAC present in the chassis that is IPv6 capable. Enable iDRAC IPv6 Autoconfiguration Enables the iDRAC to obtain IPv6 settings (address and prefix length) from a DHCPv6 server and also enables stateless address auto configuration. By default, this option is enabled.
NOTE: You must select the Enable LAN option to specify the IPv4 or IPv6 settings. For information about the fields, see the Online Help. 3. To deploy the setting to iDRAC, click Apply iDRAC Network Settings. Any changes made to the QuickDeploy Settings are also saved.

A user may be able to launch iDRAC web interface without having to login a second time, as this feature utilizes single sign-on. Single sign-on policies are: • A CMC user who has server administrative privilege, is automatically logged into iDRAC using single sign-on. Once on the iDRAC site, this user is automatically granted Administrator privileges. This is true even if the same user does not have an account on iDRAC, or if the account does not have the Administrator’s privileges.
• The browser on host system allows pop-up windows (pop-up blocking is disabled). Remote Console can also be launched from the iDRAC Web interface. For more details, see the iDRAC User’s Guide available at dell.com/support/manuals. Launching Remote Console from Chassis Health Page To launch a remote console from the CMC Web interface: 1. In the left pane, click Chassis Overview, and then click Properties. 2. On the Chassis Health page, click the specified server in the chassis graphic. 3.
Configuring CMC To Send Alerts 8 You can set alerts and actions for certain events that occur on the chassis. An event is generated when a device or service’s status has changed or an error condition is detected. If an event matches an event filter and you have configured this filter to generate an alert message (email alert or SNMP trap), then an alert is sent to one or more configured destinations such as email address, IP address, or an external server. To configure CMC to send alerts: 1.
NOTE: To apply chassis events configuration changes, you must have the Alert Configuration privilege. 1. In the left pane, click Chassis Overview → Alerts. 2. On the Chassis Events page, under the Alerts Filter section, select one or more of the following categories: 3.
Choose a format that is consistent with the networking technology or infrastructure. The Test Trap functionality cannot detect incorrect choices based on the current network configuration (example, use of an IPv6 destination in an IPv4-only environment). • In the Community String field, enter a valid community name to which the destination management station belongs. This community string differs from the community string on the Chassis Overview → Network → Services page.
6. Specify the community name: racadm config -g cfgTraps -o cfgTrapsCommunityName -i where is the SNMP community to which the chassis belongs, and is the index value specified in steps 4 and 5. You can configure up to four destinations to receive traps alerts. To add more destinations, do the tasks in steps 2–6. NOTE: The commands in steps 2–6 overwrites any existing settings configured for the index specified (1–4).
Configuring EMail Alert Settings Using RACADM To send a test email to an email alert destination using RACADM: 1. Open a serial/Telnet/SSH text console to CMC and log in. 2. Enable alert generation: racadm config -g cfgAlerting -o cfgAlertingEnable 1 NOTE: Only one filter mask may be set by both SNMP and email alerting. If you have already set a filter mask, do not perform the task in step 3. 3.
9 Configuring User Accounts and Privileges You can set up 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 • • Provides services to the chassis, such as date and time, firmware update, and CMC reset. Is associated with the chassis, such as slot name and slot priority. Although these properties apply to the servers, they are strictly chassis properties relating to the slots rather than the servers themselves. For this reason, slot names and slot priorities can be added or changed whether or not servers are present in the slots.
Privilege Description password. If the user does not exist on the server, or if the password does not match, the user is denied the ability to perform the action. If the user exists on the target server and the password matches, the server responds with the privileges of which the user was granted on the server. Based on the privileges responding from the server, CMC firmware decides if the user has the right to perform the action.

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.
NOTE: For a list of valid bit mask values for specific user privileges, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. The default privilege value is 0, which indicates that the privileges of a user are not enabled.
Configuring Active Directory Users If your company uses the Microsoft Active Directory software, you can configure the software to provide access to CMC, allowing you to add and control CMC user privileges to your existing users in your directory service. This is a licensed feature. NOTE: On the following Operating Systems, you can recognize the users of CMC users by using Active Directory.

Using FlexAddress and FlexAdress Plus Cards 12 This section provides information about FlexAddress, FlexAddress Plus Cards, and configuring and using these the cards. NOTE: An Enterprise License must be installed on the CMC to use the Flexaddress feature. About FlexAddress The FlexAddress feature is an optional upgrade that allows server modules to replace the factoryassigned World Wide Name and Media Access Control (WWN/MAC) network IDs with WWN/MAC IDs provided by the chassis.
. NOTE: Lock the SD card prior to inserting in the USB Memory Card Reader to prevent accidently modifying any of the contents. You must unlock the SD card before inserting into CMC. About FlexAddress Plus The FlexAddress Plus is a new feature added to the feature card version 2.0. It is an upgrade from FlexAddress feature card version 1.0. FlexAddress Plus contains more MAC addresses than the FlexAddress feature.
NOTE: The SD card contains a FlexAddress feature. Data contained on the SD card is encrypted and may not be duplicated or altered in any manner, because it may inhibit system function and cause the system to not function properly. NOTE: The use of a SD card is limited to one chassis only. If you have multiple chassis, you must purchase additional SD cards. Activation of the FlexAddress feature is automatic on restart of CMC with the SD feature card installed.
Table 25. Status Messages Returned by the featurecard -s Command Status Message Actions No feature card inserted. Check CMC to verify that the SD card was properly inserted. In a redundant CMC configuration, ensure that the CMC with the SD feature card installed is the active CMC and not the standby CMC. The feature card inserted is valid and contains the following feature(s) FlexAddress: bound. No action required.
NOTE: The SD card must be physically installed in CMC, and the chassis must be turned off before running the deactivation command. If you run the deactivation command without installing an SD card, or with a card from a different chassis installed, the feature is deactivated and change is not made to the card.
• MAC addresses for all the slots in the chassis Fabric Configuration Fabric A displays the type of the Input/Output fabric installed. iDRAC displays the server management MAC address. NOTE: If Fabric A is enabled, unpopulated slots display chassis-assigned MAC addresses for Fabric A. WWN/MAC Addresses Displays FlexAddress configuration for each slot in the chassis. Information displayed includes: • Slot number and location. • FlexAddress is active or not active. • Fabric type.
You must purchase and install the FlexAddress upgrade to configure the FlexAddress. If the upgrade is not purchased and installed, the following text is displayed on the Web interface: Optional feature not installed. See the Dell Chassis Management Controller Users Guide for information on the chassis-based WWN and MAC address administration feature. To purchase this feature, please contact Dell at www.dell.com.

Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.
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.
Monitoring IOM Health For information about monitoring IOM health, see Viewing Information and Health Status of the IOM. 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.
You can set the user name, password, and SNMP string for the IOM using the RACADM deploy command: racadm deploy -m switch -u -p racadm deploy -m switch -u -p -v SNMPv2 ro racadm deploy -a [server|switch] -u -p Managing Power Control Operation for I/O Modules For information to set the power control operation for I/O Module(s), see Executing Power Control Operations on the IOM.
Managing and Monitoring Power 14 The Dell 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.
PSUs beyond those required for power and redundancy are still available and is added to the pool in the event of a failure. Unlike Grid redundancy, when power supply redundancy is selected, CMC does not require the PSU units to be present in any specific PSU slot positions. NOTE: Dynamic Power Supply Engagement (DPSE) allows PSUs to be placed in standby. The standby state indicates a physical state of PSUs that are not supplying power.
An increase in power demand in the Grid Redundancy configuration cause the engagement of PSUs from the Standby state. This maintains the mirrored configuration needed for dual-grid redundancy. NOTE: With DPSE in enabled state, if power demand increases in both the two Power Redundancy policy modes, the standby PSUs are brought Online to reclaim power.
CMC allocates power to the CMC infrastructure and the servers in the chassis. CMC infrastructure consists of components in the chassis, such as fans, I/O module, and storage adapters, PCIe cards, physical disk, main board. The chassis may have up to four servers that communicate to the chassis through an iDRAC. For more information, see the iDRAC7 User’s Guide at dell.com/support/manuals. iDRAC provides CMC with its power envelope requirements before powering up the server.
Additional servers can be powered up in the modular enclosure only if sufficient power is available. The System Input Power Cap can be increased any time up to a maximum value of 5000 Watt to allow the power up of additional servers.
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.

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.
the chassis that is below what would be required for full power allocation to the servers, or if insufficient power is available in case higher power requirements by all servers in the chassis. If enough power cannot be freed by reducing the allocated power of the low-priority servers, the new server is not allowed to turn on.
Power Supply and Redundancy Policy Changes in System Event Log Changes in the power supply state and power redundancy policy are recorded as events. Events related to the power supply that record entries in the system event log (SEL) are power supply insertion and removal, power supply input insertion and removal, and power supply output assertion and de-assertion. The following table lists the SEL entries that are related to power supply changes: Table 30.
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. If all or multiple slots in the chassis are configured with the same priority level, CMC decreases power to servers in the order of increasing slot number.
those power supplies connected to the other voltage level are turned off and indicated as not functioning. Remote Logging Power consumption can be reported to a remote syslog server. Total chassis power consumption, minimum, maximum, and average power consumption over a collection period can be logged.

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 remove an assigned PCIe slot from 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 currentlyassigned server (source) is turned on.
• Without a license, the maximum number of PCIe slots that maybe mapped to a half-height server is two. If a full-height server is installed you can map two PCIe slots to the upper server slot and two to the lower (extended) server slot, for a total of four PCIe slots per full-height server. • You can map the server slots to any of the 8 PCIe slots. • A full-height server has both upper and lower mezzanines populated.
All these processes require few seconds to complete which causes a delay in initialization of the PCIe cards. The PCIe Ride-through feature in CMC VRTX reduces this process cycle time. The PCIe Ridethrough feature enables the following: • The Server nodes are turned on quickly, thus turning on the PCIe cards quickly. • The powered state of PCIe cards is extended for a pre-defined time period in the following scenarios: – After the associated server is turned off. – After a CMC stops functioning.
3. In the Timeout field, enter the time for which the Ride-through feature to be enabled. Type either zero (0) or a value from 60–1800 seconds. Zero indicates an infinite timeout. 4. Click Apply.

racdump includes the following subsystems and aggregates the following RACADM commands. For more information about racdump, see the RACADM Command Line Reference Guide for CMC in PowerEdge VRTX.
– Resolution A: This configuration requires at least one power supply in side 1 (the left two slots) and one power supply in side 2 (the right two slots) to be present and functional in the modular enclosure. Additionally the capacity of each side must be enough to support the total power allocations for the chassis to maintain Grid redundancy. (For full Grid Redundancy operation, make sure that a full PSU configuration of four power supplies is available.
• Problem: The least priority servers lost power after a PSU failure. – Resolution: To avoid a future power supply failure causing servers to power off, make sure that the chassis has at least three power supplies and is configured for the Power Supply Redundancy policy to prevent PSU failure from impacting server operation. • Problem: Overall server performance decreases when the ambient temperature increases in the data center.

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 • IOM 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.
Managing and Recovering a Remote System Why are the remote RACADM and Web-based services unavailable after a property change? It may take a minute for the remote RACADM services and the web interface to become available after the CMC Web server resets. The CMC web server is reset after the following occurrences: • Changing the network configuration or network security properties using the CMC web user interface.
When accessing the CMC Web interface, a security warning stating that the host name of the SSL certificate does not match the host name of CMC is displayed. 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 if the default certificate does not match the host name of CMC (for example, the IP address).
Are there any restrictions on Domain Controller SSL configuration? Yes. All SSL certificates for Active Directory servers in the forest must be signed by the same root certificate authority-signed certificate, because CMC only allows upload of one trusted certificate authority-signed SSL certificate. The Web interface does not launch after a new RAC certificate is created and uploaded.
If the chassis service tag is reprogrammed, what happens if there is a feature card bound to that chassis? • If the original feature card is present in the active CMC on that or any other chassis, the Web interface displays the following error message: This feature card was activated with a different chassis. It must be removed before accessing the FlexAddress feature.
What happens to FlexAddress if I need to reset my chassis configuration using the RACADM command, racresetcfg? The FlexAddress feature will still be activated and ready to use. All fabrics and slots are selected as default. NOTE: It is highly recommended that you turn off your chassis before running the RACADM command racresetcfg.
