If you did not check the Use another database server option during installation, the uninstall program removes the Power Center database and configurations. If you checked the Use another database server option and used another database during the installation, the uninstall program does not uninstall the database. Launching Power Center In Windows Open a Web browser. You may need to configure your Web browser to launch Power Center.
Installing, Uninstalling, and Launching Power Center In Linux This section explains how to install, uninstall, and launch Power Center on Linux platforms. Installing Power Center On A Linux Server To install Dell OpenManage Power Center, you must have Administrator privileges. Before installing Power Center, verify that your system meets the minimum system requirements. NOTE: Use –prefix=
to save the installation binary file to a location other than the default path. 1.NOTE: The password must be a minimum of 8 characters in length with characters from at least three of the following categories: uppercase, lowercase, numeric, non-alphanumeric. The password can include spaces. – PostgreSQL Port—The default value is 6443. If another database is already using the default port, enter a different port. – PostgreSQL Data Directory—The location of PostgreSQL data. Press to continue.
To start, stop, or restart Power Center service, use the following command: #service ompcdaemons start|stop|restart|status Uninstalling Power Center In Linux NOTE: Make sure to remove all devices from the Power Center management console before uninstalling Power Center. Otherwise, the existing power cap value set in the policies (including EPR) will remain effective on the devices.
Command Line Interface 4 All of the commands supported by the command line interface (CLI) have the following format: ompc_cli [COMMAND] [GENERIC_OPTIONS] [COMMAND_OPTIONS] [COMMAND_TARGET] The operation must start with a valid [COMMAND]. Options can be entered anywhere after [COMMAND]. For each option that has a value, the value must be supplied immediately after the option. NOTE: If a duplicate or incorrect option value is supplied with a command, the CLI will exit with an error.
Command Line Interface Commands NOTE: In the following commands, [ ] represents optional attributes and < > represents variables. All command line text is case insensitive. help Usage: ompc_cli help [] [] The help command prints the help content for a command or a command option (including the generic option). Authentication is not required for the help command.
• wsman_password • wsman_validate_cert (its value must be true or false) update_profile Usage: ompc_cli update_profile [-description ] [] [] The update_profile command updates an existing discovery profile identified by profile_name in OMPC. The semantics of the command options are the same as those in add_profile. The protocol property set that can be updated depends on the protocol supported by this profile.
After rediscovery, the Time of Discovery is updated to the time of rediscovery. For the Chassis Management Controller (CMC), if you are rediscovering it before adding it to the rack (in other words, the blades inside it are not enumerated), it will not trigger enumerating blades inside it. If rediscovering a CMC after it is added to rack (the blades inside it are enumerated), OMPC will enumerate blade changes inside it to reflect any changes. You cannot use -service_tag and device_name at the same time.
If the [-preview] option is given, a summary of the groups, devices, and policies impacted will display. No deletion occurs. • The summary includes the number of impacted devices, number of impacted groups, and number of impacted policies. • All subgroups under the specified group path are counted in the summary whether they will be deleted from OMPC or not.
adding a server or chassis to rack, -slot is allowed (when not provided, the system will choose a slot automatically). If adding a server or chassis to other groups, -slot is not allowed (an error will display). Slots start from 1 (0 is an invalid slot number). PDU and UPS can only be added to a rack. For PDU and UPS in other types of groups in a previous OMPC release, if the you upgrade the data, you must remove PDU and UPS from those groups after upgrading.
You cannot use the attributes -service_tag and device_name at the same time. If the move operation fails, the device stays in the original group. There are exceptions for critical situations such as power failures, crashes, network failures for the remote database, and local network failures. move_group Usage: ompc_cli move_group FROM_GROUP_PATH TO_GROUP_PATH The move_group command moves a group from FROM_GROUP_PATH to TO_GROUP_PATH. You cannot use the same group path as FROM_GROUP_PATH to TO_GROUP_PATH.
list_device_props Usage: ompc_cli list_device_props [-service_tag ] [] The list_device_props command lists all properties for the device identified by servtag or device_name. Properties include service_tag, protocol, protocol properties, device name, address (IP or host name), model, and device type (device name is the first column). Secret data (password/key) is not listed as a protocol property.
find_device Usage: ompc_cli find_device [-service_tag ] The find_device command is used to list all of the fully-qualified group names of the groups to which the device that is identified by servtag or device_name belongs. You cannot use service_tag and device_name at the same time. Command Line Interface Error Codes An error code appears when one of the following two conditions occurs: • The CLI identified an error, such as a command or command option validation error.
• Infrastructure — 0x16 • Unknown — 0xFF

Power Monitoring 10 Power Center enables the monitoring of current or historical power-related metrics (for example, power consumption or cost). This can help you understand the power status in the data center and plan for additional power infrastructure, cooling, and facility needs. You can monitor power at different device and/or group levels. You can configure power monitoring settings to meet your monitoring needs, and you can print the power status graph.
When the average power exceeds this setting, the critical-level event “Average Power” is sent. – Warning Threshold (BTU/hr) for Custom Max Power Group When the maximum power exceeds this setting, the warning-level event “Max Power” is sent. – Warning Threshold (BTU/hr) for Custom Average Power Group When the average power exceeds this setting, the warning-level event “Average Power” is sent. 6. Click Apply.
Power Details for a Different Time Window Click the arrows < > to view the details for the previous/next sampling time, or click the double arrows << >> to view the details for the previous/next page of results for the current time window. You can click Average, Maximum, or Minimum to display the selected value. • Average: The average value from the previous time point to the current time point. • Maximum: The maximum value from the previous time point to the current time point.
• Energy Consumed (Total) — The combined energy consumption and costs for the IT equipment and cooling energy. The formula is: Cost = (IT Equipment Energy T1*Cooling Multiplier) *Flat Rate T1+(IT Equipment Energy T2*Cooling Multiplier) *Flat Rate T2+°¦+(IT Equipment Energy Tn*Cooling Multiplier) *Flat Rate Tn NOTE: T1/T2/.../Tn is the time period (in hours) at a certain flat rate. NOTE: By default, the Cost column displays 0. You must configure the cost rate to see the cost.
For groups: – The left box shows the aggregated power value of the latest sampling interval for the devices with Monitor power capability in the group. – The right box displays the level of the aggregated power value compared with the power thresholds you set in the Thresholds tab. NOTE: Aggregated power value is the power value calculated by the power data aggregation. The calculation formula is case-by-case, and depends on whether the data aggregation is based on time periods or groups.
Temperature Monitoring 11 Power Center enables monitoring of the current or historical temperature of the data centers in Power Center. This can help you understand the temperature status and identify hot spots in the data center. You can monitor the temperature status at different device/group levels. You can configure the temperature monitoring settings to meet your monitoring needs, and you can print the temperature status graph.
6. – Warning thresholds for average inlet temperature - Greater — When the temperature is greater than the setting, the warning-level event "Average Inlet Temperature" is sent. – Warning thresholds for average inlet temperature - Less — When the temperature is less than the setting, the warning-level event "Average Inlet Temperature" is sent. Click Apply. After you have configured the thresholds, you will see four lines with different colors indicating the thresholds in the Temperature Details tab.
• Minimum: The minimum value from the previous time point to the current time point. For example, you view temperature details in the 1H (1 hour) window and the maximum value at 15:00 shows 40°C and the time interval is 6 minutes. This value would represent that the maximum temperature from 14:54 to 15:00 is 40°C. Chassis Details The Chassis Details table appears when you access the Temperature Details page on a chassis.
– The right box displays the level of the aggregated temperature value compared with the temperature thresholds you set in the Thresholds tab. NOTE: Aggregated temperature value is the temperature value calculated by the temperature data aggregation. The calculation formula is case-by-case, and depends on whether the data aggregation is based on time periods or groups.
Policies 12 A power policy is a set of configurations used to manage the power cap for a device or group. A policy is useful for power management in different situations. For example, you can set up a policy to: • Make sure power consumption does not exceed the capacity of the circuit. • Schedule power usage according to the workload of the device/group. For example, you can set an aggressive cap when the workload is low, enabling a reduction of power use for your data center.
Dynamic Power Caps The following terms are helpful for understanding how a dynamic power cap works: • Consumption: The amount of power a device is using. • Power Cap: The maximum amount of power that a device is allowed to consume (may not be equal to its demand). • Headroom: The difference between power cap and power consumption of a device or a group of devices under a power policy. • Demand: Amount of power a device requests to accommodate its workload.
• The Policies tab of the devices is set to disabled in the Groups page. • The power capability status of the devices is set to "None" in the Devices page. • You cannot edit the policy of this device from the Policies page; you can only delete it. Scenario 2 — You try to import a license on a device without a license imported In this case, the following happens: • If a policy exists on the devices, you will receive a "Server Capabilities Changed" event.
* Dynamic policy—Set the priority (High, Medium, and Low) for individual devices in the group. Power Center reserves more of the budgeted power for the devices/groups with a higher priority when the power budget is not completely utilized. * Static policy—Enter values for the Power Cap or Percentage of Capability, if desired. By default, Power Center uses the same percentage of the Upper Bound value as the power cap for every device.
• Medium (Default) • High Priority lists are policy-specific; however, a device/group may have different priority levels in different policies. A higherpriority value of a device/group in a policy overrides the lower-priority value of the same node in another policy. For example, you created Policy1 for device and Policy2 for device , and you configured different priorities or power caps for the policy with the same time slot.
Editing A Power Policy You can edit one power management policy at a time. 1. Do one of the following: – Click Policies in the left pane. – Click Groups in the left pane, select a group, and then click the Policies tab. 2. Click Edit next to the policy you want to change. 3. In the Edit Policy wizard, make changes to the Set Power Cap and/or Choose Schedule pages. 4. Click Apply to immediately apply changes. Deleting a Power Policy 1. Do one of the following: – Click Policies in the left pane.
4. In the Emergency Power Reduction window, read the message, and click Continue. All of the devices with the Monitor & Capping power capability within this group are set to the minimal power consumption state. The Emergency Power Reduction button appears in the upper-right corner of all pages. The devices impacted by emergency power reduction are marked with In EPR in the Groups pages. Canceling EPR 1. In the upper-right corner of any page, click Emergency Power Reduction.
Comparing 13 NOTE: If you are using Internet Explorer 8, you must install Adobe Flash Player in order for the compare function to work properly. Power Center enables you to add a device or a group to compare the device’s or group’s power and temperature status and energy consumption in the selected time period.
To change a device/group for comparison, remove the device/group first, then add a different device/group. Printing the Comparison Result To print the comparison result, click Print on the Compare page. You must set the Web browser to enable the "Print Background" option and other printing settings, otherwise the results are printed either without a background or with incorrect page alignment.
