I installed two Intel® DCM: Energy Director versions in a cluster environment where all files and folders are shared with NFS system, but I cannot open the reference UI.

We do not recommend installing two Intel® DCM: Energy Director packages in a cluster environment, especially in the environment where the home folder is NFS shared by all managed servers. If you want to install Intel® DCM: Energy Director in such an environment, please ensure the home directory is not shared.

During Intel® DCM: Energy Director installation, I enabled TLS settings, and now, I cannot open the reference UI. What is the reason?

To enable TLS settings, please make sure you have set the correct TLS configuration, and saved the configuration using the right format as TLS requested. Then, you need to open the reference UI with the URL: https://localhost:8643/DataCenterManager, where D, C and M are capitalized.

I have installed the Intel® DCM: Energy Director package successfully on Linux* operating system, but when I try to open the Intel® DCM: Energy Director reference UI locally with the URL: http://localhost:8688/DataCenterManager, it always fails.

For this issue, please make sure the following steps are configured as follows:

  • The firewall has been turned off, or Intel® DCM: Energy Director has been added into firewall permission list.
  • The SELinux* has been disabled, or Intel® DCM: Energy Director has been added into SELinux permission list.
  • There is no proxy configuration in Firefox browser.
  • The computer name has been bundled with localhost in host’s config file.
  • The flash player plug-in has been installed successfully.
  • If the computer name is localhost, please make sure there is no other computer in the network named as the same name (localhost).

When I try to install Intel® DCM: Energy Director on operating system Cent 5.5* x64 Edition, during installation, there is an error reported: "error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory." And the installation failed.

Officially, Intel® DCM: Energy Director does not support installation on this operating system. As to the issue itself, the reason for this is that Cent operating system has no lib file: libxml2.so.2, which is one of Intel® DCM: Energy Director's dependencies. We suggest installing this file first, and then installing Intel® DCM: Energy Director.

I have installed the Intel® DCM: Energy Director package successfully on Windows* operating system, but when I try to open the Intel® DCM: Energy Director reference UI locally with the URL: http://localhost:8688/DataCenterManager, it always fails.

For this case, please make sure the following steps are configured as follows:

  • The firewall has been turned off, or Intel® DCM: Energy Director has been added into firewall permission list.
  • The flash player has been installed successfully.

How can I open Intel® DCM: Energy Director reference UI remotely?

By default, Intel® DCM: Energy Director uses the computer name to make the identification in the network. So if there is no DNS in network, to open Intel® DCM: Energy Director reference UI remotely we can use the Intel® DCM: Energy Director server IP address as the URL: http://DCMserverIPAddress:8688/DataCenterManager. Before opening the URL, we need to change the settings.xml file, which is located in the Intel® DCM: Energy Director installation folder, for example:

  • C:\Program Files\Intel\DataCenterManager\external\apache-tomcat\webapps\DataCenterManager\Settings.xml
  • Alternatively for Linux operating system: /opt/Intel/DataCenterManager/external/apache-tomcat/webapps/DataCenterManager/Settings.xml

In this file, we change the computer name to the relevant IP address. There are four places which need to be changed in this file. After modifying this file, and saving the changes, restart the Intel® DCM: Energy Director services>. Visit the Intel® DCM: Energy Director reference UI remotely by inputting the URL above.

I changed the computer name after I installed Intel® DCM: Energy Director successfully. Now, I cannot open the reference UI, even if I restart the Intel® DCM: Energy Director services.

This is because once Intel® DCM: Energy Director is installed, the computer name will be filed in one Intel® DCM: Energy Director database config file. Once the computer name changes, the config file will mismatch with the new computer name. The steps to solve this use case:

  1. Change the computer name to the original one
  2. Uninstall Intel® DCM: Energy Director package
  3. Change the computer name to the new one
  4. Reinstall Intel® DCM: Energy Director

When I add a managed server to the Intel® DCM: Energy Director hierarchy, an error pops up: "Managed server Discovery End with Error: Managed server is not reachable." What is the reason?

This error is mainly caused by an IPMI session which is not set up. Please make sure the BMC IP address is correct and can be reached by Intel® DCM: Energy Director server through the network; also, make sure the managed server BMC has been enabled for LAN access.

When I add a managed server to the Intel® DCM: Energy Director hierarchy, an error pops up: Managed server Discovery EndwWith Error: "Response failed with error code: (17) No Cipher Suite match with proposed security algorithms." What is the reason?

This error is mainly because of the BMC LAN channel cipher suite privilege setting, which does not comply with the Intel® DCM: Energy Director requirement as follows.

Intel® DCM: Energy Director requests that one of the first four BMC LAN channel cipher suites: cipher suite 0-3, must have ADMIN privilege. Try using IPMItool to change the BMC LAN channel cipher suite privilege settings, then try to add to Intel® DCM: Energy Director again.

When I add a managed server to the Intel® DCM: Energy Director hierarchy, an error pops up: "Managed server Discovery End with Error: "Response failed with error code: (13) Unauthorized name." What is the reason?

This error is mainly because you have input a nonexistent BMC user, or the BMC user input is not enabled. Please use IPMItool to check the BMC user information, and enable the correct user for Intel® DCM: Energy Director, then try to add to Intel® DCM: Energy Director again.

When I add a managed server to the Intel® DCM: Energy Director hierarchy, an error pops up: "Managed server Discovery End with Error: "Response failed with error: User-Password authentication check failed (RAKP 2 check) (17)." What is the reason?

This error is mainly because the authentication check cannot be passed. You may have input the wrong password. If you’ve forgotten the password, please use IPMItool to reset the password, then, try to add in Intel® DCM: Energy Director again.

When I add a managed server to the Intel® DCM: Energy Director hierarchy, an error pops up: "Managed server Discovery End with Error: "Response failed with error: Set session privilege level to level (4) failed: (0x81) Requested level exceeds Channel or User Privilege Limit." What is the reason?

This error is mainly because the BMC user input does not have ADMIN privileges. Intel® DCM: Energy Director requesting the BMC username used for communication has ADMIN privilege. Please use IPMItool to check the BMC user information, and change the relevant user to ADMIN privilege level, then try to add Intel® DCM: Energy Director again.

When I add a managed server to the Intel® DCM: Energy Director hierarchy, I think I have correctly configured the managed server BMC, including cipher suite, user privilege, and password setting, but I still cannot add this managed server to Intel® DCM: Energy Director.

  • Be sure you have chosen the right connector name when adding the managed server.
  • Be sure the BMC IP address can be reached by IPMI.
  • If you add a Node Manager managed server, be sure this server platform is a Node Manager-enabled platform, the ME function has been enabled in BIOS (for some platforms), the BMC SDR already contains the Node Manager OEM SDR list, and Node Manager can be reached through IPMI raw command.

I have added the managed server into the Intel® DCM: Energy Director hierarchy successfully, in order to verify Intel® DCM: Energy Director. I also want to use IPMI raw command to operate Node Manager directly. How do I locate the Node Manager slave address and channel number?

There are two ways to get the Node Manager slave address and channel number:

  • Using the IPMItool, dump the SDR file, find the Node Manager OEM SDR (57 01 00 0D), and get the Node Manager slave address and channel number from the Node Manager OEM SDR list
  • Open the Intel® DCM: Energy Director reference UI, change log level to trace <configuration Global option log level>, and add the managed server or rediscover the managed server. After successfully adding the managed server, open the Intel® DCM: Energy Director log file (in the Intel® DCM: Energy Director installation folder), find the string which contains ‟Found Intel Node Manager technology Discovery SDR. rsAddr=??, targetChannelNum=?." The rsAddr is the Node Manager I2C address and targetChannelNum is the target channel.

I have added the server node into the Intel® DCM: Energy Director hierarchy successfully, but power readings are not available for a long time.

  1. Make sure you have started the function to get a power reading (click the resuming monitoring button in the upper corner of the reference UI).
  2. Make sure you have waited 3 to 6 minutes after resuming the power monitoring.
  3. Make sure your local time has been synced up with Intel® DCM: Energy Director server time.
  4. Make sure the server node BMC is online and can be reached through the Intel® DCM: Energy Director server.

If the problem remains, please use IPMItool raw command to reach the Node Manager and check if this is working well.

I have one HP platform with an iLO 2 system. Can I use Intel® DCM: Energy Director to manage this managed server?

Intel® DCM: Energy Director can manage or monitor HP servers with an iLO2 or iLO3 system. To manage the platform with an iLO2 system:

  • Update the HP server firmware to the latest version.
  • Add the managed server to the Intel® DCM: Energy Director hierarchy with the connector name Data Center Manageability Interface.
  • If you want to do power capping on HP platform, you need to activate the HP iLO2 license. After the activation, the managed servers need to be power-cycled and rediscovered to work with Intel® DCM: Energy Director on power capping.

I have added the server node to the Intel® DCM: Energy Director hierarchy successfully, to verify Intel® DCM: Energy Director. I also want to use IPMI raw command to operate Node Manager directly. How do I know the Node Manager slave address and channel number?

There are two ways to get the Node Manager slave address and channel number:
Using IPMItool, dump the SDR file, find the Node Manager OEM SDR (57 01 00 0D), and get the Node Manager slave address and channel number from the Node Manager OEM SDR list. Open Intel® DCM: Energy Director reference UI, change log level to trace <configuration Global option log level>, and add the node or rediscover the node. After successfully adding the node, open the Intel® DCM: Energy Director log file (in the Intel® DCM: Energy Director installation folder), and find the string which contains ‟Found NM Discovery SDR. rsAddr=??, targetChannelNum=?”. The rsAddr is the Node Manager I2C address and targetChannelNum is the target channel

I have added a managed server to the Intel® DCM: Energy Director hierarchy, and can monitor the power reading successfully, but when I set the power policy, there seems to be no effect.

  • Make sure the enhanced Intel® SpeedStep technology feature has been enabled in BIOS
  • Ensure the managed server operating system supports ACPI3.0 (or later) and ACPI service in the managed server operating system has been started by default. Popular operating systems (Windows* 2003, Windows* 2008, RHEL5, SUSE10, SUSE11, etc.) already support ACPI 3.0. If you want get more information about ACPI, please visit http://www.acpi.info.
  • Make sure the server managed operating system supports ACPI3.1 (or later), and ACPI service in server managed operating system has been started.
  • If the managed server has no active workload and remains idle, the power reading may be accurate, but may not change until the managed server is active again.

In my Intel® DCM: Energy Director reference UI, there is always one error message that pops up: "Failed to subscribe predefined event ..." What does this mean?

This means that the Intel® DCM: Energy Director predefined event cannot be subscribed on the target managed server. Predefined events will not pop up when they are triggered, primarily because there are no available BMC SEL selectors for Intel® DCM: Energy Director to subscribe the predefined events. To solve this, make sure there are free SEL selectors in the managed server BMC.

I added one managed server to the Intel® DCM: Energy Director hierarchy. But, when I want to import the original Intel® DCM: Energy Director hierarchy into the current Intel® DCM: Energy Director version, the importation always fails.

If you want to import an Intel® DCM: Energy Director hierarchy, make sure there are no entities or managed server groups in the Intel® DCM: Energy Director UI. You’ll need to delete any existing entities before importing another Intel® DCM: Energy Director hierarchy. This, by design, will avoid the conflict.

I have imported the old Intel® DCM: Energy Director hierarchy into my current Intel® DCM: Energy Director reference UI, and resumed power monitoring, but I cannot get the power readings. If I manually add the managed servers, I can get the power readings. Why?

Due to security concerns, when exporting the hierarchy, the managed server BMC password has not been exported. This means that after importing, there is no BMC password, the authentication check will fail, and there will be no power readings. In this case, two methods can be considered:

  • Import the hierarchy into Intel® DCM: Energy Director reference UI, change the managed servers' property, add the BMC password manually, and run rediscovery.
  • Edit the hierarchy xml file, add the BMC_PASSWORD property field for the relevant managed servers, and import the new modified hierarchy xml file.
