The config subcommand loads the information into other CMCs. The Server Administrator uses the config command to synchronize the user and password database. Creating a CMC Configuration File The CMC configuration file, .cfg, is used with the racadm config -f .cfg command to create a simple text file. The command allows you to build a configuration file (similar to a .ini file) and configure the CMC from this file. You may use any file name, and the file does not require a .
• If you type racadm getconfig -f .cfg, the command builds a .cfg file for the current CMC configuration. This configuration file can be used as an example and as a starting point for your unique .cfg file. Parsing Rules • Lines that start with a hash character (#) are treated as comments. A comment line must start in column one. A "#" character in any other column is treated as a # character. Some modem parameters may include # characters in their strings. An escape character is not required.
NOTE: A NULL string (identified by two " characters) directs the CMC to delete the index for the specified group. To view the contents of an indexed group, run the following command: racadm getconfig -g -i • For indexed groups the object anchor must be the first object after the [ ] pair.

Launching iDRAC using Single Sign-On CMC provides limited management of individual chassis components, such as servers. For complete management of these individual components, CMC provides a launch point for the server’s management controller (iDRAC) web-based interface. A user may be able to launch iDRAC web interface without having to login a second time, as this feature utilizes single sign-on.
• The chassis power is on. • Servers that support iDRAC7 and iDRAC8. • The LAN interface on the server is enabled. • The host system is installed with JRE (Java Runtime Environment) 6 Update 16 or later. • 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.
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.
3. • System Health • Storage • Configuration • Audit • Updates Select one or more of the following severity levels: • Critical • Warning • Informational The Monitored Alerts section displays the results based on the selected category and severity.

To determine whether an index has previously-configured values, type: racadm getconfig -g cfgTraps -i . If the index is configured, values appear for the cfgTrapsAlertDestIPAddr and cfgTrapsCommunityName objects. 7. To test an event trap for an alert destination, type: racadm testtrap -i where is a value between 1–4 representing the alert destination you want to test.
where is a hexadecimal value between 0x0 and 0xffffffff and must be expressed with the leading 0x characters. The Event Traps Filter Masks table provides filter masks for each event type. For instructions about calculating the hex value for the filter mask you want to enable, see step 3 in the Configuring SNMP Trap Alert Destinations Using RACADM. 4. Enable email alert generation: racadm config -g cfgEmailAlert -o cfgEmailAlertEnable 1 -i where is a value between 1–4.
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 • • • Is assigned specifically to the chassis, such as IP mode (static or DHCP), static IP address, static gateway, and static subnet mask. 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.
Privilege Description When a CMC user who does not have Server Administrator privilege issues an action to be performed on a server, CMC sends a command to the targeted server with the user’s login name and 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.

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.

For more information about the sshpkauth, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. Generating Public Keys for Systems Running Windows Before adding an account, a public key is required from the system that accesses the CMC over SSH. There are two ways to generate the public/private key pair: using PuTTY Key Generator application for clients running Windows or ssh-keygen CLI for clients running Linux.
• For the –i option, the parameter must be svcacct. All other parameters for -i fail in CMC. The svcacct is a special account for public key authentication over SSH in CMC. • To log in to the CMC, the user must be service. Users of the other categories do have access to the public keys entered using the sshpkauth command. Viewing Public Keys To view the public keys that you have added to the CMC, type: racadm sshpkauth –i svcacct –k all –v To view one key at a time, replace all with a number from 1 – 6.

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 If a server is replaced, the FlexAddress for the slot remains the same for the given server slot.
card contains an XML tag mac_start that is the first starting hex MAC address that is used for this unique MAC address range. The mac_count tag is the total number of MAC addresses that the SD card allocates. The total MAC range allocated can be determined by: + - 1 = For example: (starting_mac)00188BFFDCFA + (mac_count)0xCF - 1 = (ending_mac)00188BFFDDC8 .
Table 26. 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.
Deactivating FlexAddress The FlexAddress feature can be deactivated and the SD card returned to a preinstallation state by using a RACADM command. There is no deactivation function within the Web interface. Deactivation returns the SD card to its original state where it can be installed and activated in another chassis. The term FlexAddress, in this context, implies both FlexAddress and FlexAddressPlus.
NOTE: FlexAddress does not take effect on a server module until the next reboot. When the FlexAddress feature is deployed for the first time on a given server module, it requires a powerdown and power-up sequence for FlexAddress to take effect. FlexAddress on Ethernet devices is programmed by the server module BIOS. For the server module BIOS to program the address, it needs to be operational which requires the server module to be powered up.
For more information about the setflexaddr command, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide. NOTE: If you purchase the FlexAddress or FlexAddressPlus feature with your Dell PowerEdge VRTX, it is preinstalled and enabled for all slots and fabrics. To purchase this feature, contact Dell at dell.com. NOTE: By using the racresetcfg subcommand, you can reset the Flex Address of a CMC to its factory-default setting, which is “disabled”.

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.
NOTE: For Ethernet switches, the in-band (VLAN1) and out-of-band management IP addresses cannot be the same, or cannot be on the same network. This results in the out-of-band IP address in being not set. See the IOM documentation for the default in-band management IP address. NOTE: Do not configure I/O module network settings for Ethernet pass-through and Infiniband switches. Configuring Network Settings for IOM Using CMC Web Interface To configure the network settings for I/O Module: 1.
Managing and Monitoring Power 14 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.
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 iDRAC 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. 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.
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 31.
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. For more information about enabling this feature and configuring the collection or logging interval, see Managing and Monitoring Power.

failover process since the redundant components(controllers) are not used during normal operating conditions. High Availability with fault-tolerance provides the following benefits: • Provides uptime for all storage applications even when a controller stops functioning. • Provides access to critical functions of the chassis at all times. • Enables server to handle situations when controller stops functioning are becomes faulty.
To import or clear the foreign configuration: 1. In the left pane, click Chassis Overview → Storage → Controllers → Setup. 2. On the Controller Setup page, in the Foreign Configuration section, for the respective controller, click: • Clear Foreign Configuration to clear the existing configuration of the disk. • Import/Recover to import the disk with the foreign configuration.
Shared PERC Controllers For VRTX systems shipped with two PERC controllers, the second PERCs may have been disabled. In this mode the chassis does not operate in Fault Tolerant mode. The system then operates as a single Shared PERC system with only one active controller operating in Performance mode. From the RACADM Command Line Interface, run theracadm raid get controllers command to list the number of Shared PERC controllers on your system. If the command lists only RAID.ChassisIntegrated.
You can disable a peer controller only if: • All the servers in the chassis are turned off. • The Integrated 1 PERC is currently the active controller. NOTE: If the Integrated 1 PERC is not currently the active controller, then perform a chassis power cycle to make this the active controller. • Both CMCs have the same firmware version that supports this feature. NOTE: After disabling Integrated 2 PERC , to replace a CMC card, it is recommended to update the CMC card with firmware version 1.
NOTE: For fault-tolerant mode, the following attributes are also displayed: • Active controller — Shared PERC8 (Integrated 1) • Redundant/Failover controller — Shared PERC8 (Integrated 2) You can also use the following filters to view specific physical disk drive's properties: • Under the Basic Physical Disks Filter option , from the Group By drop-down menu, select Virtual Disk, Controller, or Enclosure, and then click Apply.

On the Manage Virtual Disks page, from the Virtual Disk Actions drop-down menu, select one of the following actions, and then click Apply. • Rename • Delete 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.
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.

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.
