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, and nonalphanumeric. The password can include spaces 10.
Uninstalling Power Center in Linux NOTE: Ensure to remove all devices from the OpenManage Power Center console before uninstalling Power Center. Otherwise, the existing power cap value set in the policies (including EPR) will remain effective on the devices. Ensure to check your data center power capacity before removing the devices to avoid tripping the breaker, because the policies are also removed at the same time.
Using OpenManage Power Center through Command Line Interface 4 All 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.
Command Line Interface error handling On Microsoft Windows and Linux operating systems, an exit code is displayed indicating the successful execution of a command. An error code is displayed, if a command is not executed successfully. On Microsoft Windows operating system, when the command is successful, the CLI exit code is 0. Refer Command Line Interface Error Codes to know about specific error codes. On Linux operating system, when a command is successful, the CLI exit code is 0.
The protocol_name should be For IPMI, the properties are: • ipmi_user • ipmi_password • ipmi_key For SNMPv1v2c, the property is snmp_community_string. (Required).
add_device Usage: ompc_cli add_device [-device_name ] [-description ] [size ] [-estimated_max_power ] –device_type [-model ] [–profile ] [protocol ] [] [host_name or ip] The add_device command adds a device to OMPC by using the profile name-identified profile or by using related protocol information directly supplied through the comm
remove_profile Usage: ompc_cli remove_profile The remove_profile command removes a discovery profile. delete_device Usage: ompc_cli delete_device [-service_tag ] [] The delete_device command deletes a device. You cannot use –service_tag and device_name at the same time. If the device is a chassis, it is deleted like a group (if the blades in it are already enumerated). The chassis itself is also deleted from OMPC, and is no longer visible on the Devices page.
• 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 irrespective of whether they are deleted from OMPC or not deleted. It is possible that a subgroup could be removed from the specified group path, but can not be deleted from OMPC due to a reference from another parent group.
add_device_to_group Usage: ompc_cli add_device_to_group [] GROUP_PATH [-slot ] [-service_tag ] The add_device_to_group command adds a device to a group. If a device is added to a rack, the slot_num option is used to specify into which slot the device is added. If the value of the slot is -1, the system chooses a slot automatically. When adding PDU/UPS, if you do not provide a slot option, the PDU/UPS is attached to the rack.
The move_device command moves a device from FROM_GROUP_PATH to TO_GROUP_PATH. After successfully moving the device, the device no longer belongs to FROM_GROUP_PATH; it belongs to TO_GROUP_PATH. The slot option is applicable only when moving a device (including a chassis) to a rack. It specifies which slot the device should be moved into. If it is not provided when moving a device to a rack, the CLI identifies a slot.
add_group_to_group Usage: ompc_cli add_group_to_group GROUP_PATH TO_ _GROUP_PATH The add_group_to_group command adds a group identified by GROUP_PATH to TO_GROUP_PATH. If the source group path also belongs to another parent group, after successfully adding the group, the source group belongs to both the old group and the new parent group. The exception is that a chassis can only belong to one rack (not multiple racks).
If “/” is provided as GROUP_PATH, the CLI lists the devices at the root level. list_group_props Usage: ompc_cli list_group_props GROUP_PATH The list_group_props command lists all properties for a group identified by GROUP_PATH. Properties include group_type (DC, room, rack, aisle, etc.), description, and additional properties unique to that group type. For example, for rack, the additional properties include capacity and total power capacity. This command does not apply to “/”.
The list_reports command is used to list user defined reports. REPORT_GROUP is the name of a report group. If no REPORT_GROUP is supplied, all reports are listed. Else, only those belonging to the specified REPORT_GROUP are listed. Each report is output in one row containing these fields: report_name, description, format, report_group_name, created_by and status (running or not).
After a discovery is complete, the discovered devices are added to OpenManage Power Center automatically and the count is displayed in the console. If the device discovery fails, an error message is displayed. backup_database Usage: ompc_cli backup_database -path -encrypt_password [quiet] The backup_database command is used to initiate the OMPC database backup. The -path and -encrypt_password options must be supplied.

Policies 10 A power policy is a set of configurations to manage the power cap for a device or group. A policy is useful for power management in different situations. For example, you can create a policy to: • Power Cap — Make sure that power consumption does not exceed the capacity of the circuit. • Control Power Usage — Schedule power usage according to the workload of the device or group.
• Headroom — The difference between rack power capacity (specified by the user when the rack is added to the Dell OpenManage Power Center system) and rack power consumption (determined by the actual power consumption by PDUs added or associated with the rack). • Demand — Amount of power a device requests to accommodate its workload. • Estimated maximum power (Estimated max power) — The maximum power consumption allocation estimated for a device.
• 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, a "Server Capabilities Changed" event is generated.
NOTE: This step is applicable only to racks and chassis. NOTE: The following steps are applicable if you select STATIC or DYNAMIC power policy. 7. From the Power monitoring values are for a fixed time period drop-down list, select the power cap values. The possible options are: 8. 9. • Previous hour • Previous day • Previous week • Previous month • Previous quarter Enter a value in the Power Cap Value text box.
Policy Priority Levels When you create or update a policy, you can select different priority levels for each device/group. For example, you can set priority levels based on the service level agreements associated with workloads running on a device/group. Power Center tends to reserve more power to the devices/groups with higher priority when the power cap for devices/groups is not fully utilized.
3. In the task menu, click Enable or Disable. NOTE: The Enable and/or Disable menu options are available only when you select a policy. Viewing policies in the power details graph 1. In the left pane, click Devices → All Devices or Devices → Managed Groups. 2. Select the check box next to a device or device group.

– Import a certificate for your CA. – Import the Certificate Reply from the CA. • Scenario 3 – Import a new Trust Certificate. Some devices (for example, chassis and the exposed management interface through WS-MAN) or web service providers may provide a certificate for Power Center validation when establishing communication. If you validate the certificate and Power Center fails to verify it by building a trust path from the trust certificate in the keystore file, then communication fails.
Configuring settings 15 You configure the OpenManage Power Center settings in the Settings screen. The Settings screen comprises the following tabs: • General — Configure the timeout for console and device communication. • Monitoring — Configure the power/thermal units and energy consumption parameters. • Alerts — Configure alerts for SNMP traps, enable or disable sending alerts through emails, configure email recipients, and event severity-level.
By default, the General settings screen is displayed. 2. In the Protocols Timeout section, enter the time in seconds for the specified communication protocol (IPMI, SNMP, WS-MAN, HTTPS, or SSH). OpenManage Power Center considers the device not reachable if it cannot get any response from the device within the timeout period. 3. Click Save to apply your settings, Reset to revert to the previously saved settings. The new settings take effect the next time when Power Center communicates with the device.

Troubleshooting 17 This chapter lists some of the known issues you may encounter when working with Power Center. Why am I being required to log in more than once by Power Center? Possible Cause: This occurs when one of the following elements of Kerberos SSO is not correctly configured: the Power Center server, the web browser, or the AD domain controller configuration. Resolution: Correctly configure your Power Center server and web browser for Kerberos SSO.
Why did my connection to Dell iDRAC6 devices (Dell PowerEdge Servers) fail, when the network connection status is Connected? Possible Cause: Dell iDRAC6 devices are limited to three concurrent connection sessions, and you have reached the limit. There are various reasons that may cause the session to be occupied for a while until it is relinquished—for example, you used incorrect credential information to connect with Dell iDRAC6 devices for three times or more within a short period.
– If the device number is large, perform the following steps. Power Center removes the policies first, and then remove the devices. 1. Install Power Center. 2. Add all the devices to the Power Center management console. 3. Create a logical group that contains all of the devices, and then create a power policy for this group. 4. Remove all of these devices from the Power Center management console.
Why I encounter an error, “An internal error occurred. Contact Dell support for help: subordinate error code: 0x8f0c1301”, the Home page when OpenManage Power Center server is installed on SUSE Linux Enterprise Server 11 SP2? Possible Cause: SUSE Linux Enterprise Server 11 SP2 has a known time zone issue which cause power center fail to get the right time zone of server. For more information, visit www.suse.com/support/ update/announcement/2012/suse-ru-20121258-1.html.
Why is the “policy return to normal” event not displayed when the only device in the Chassis Management Controller (CMC) is deleted? Possible Cause: When the last blade in the chassis is deleted, the power value returns to “–1” as there is no device in the chassis. The comparison between the power value and the policy capping fails and the “policy return to normal” event is not triggered. Resolution: You can add a blade to the chassis if the power value does not exceed the power capping value.
A Upgrade failure recovery on Microsoft Windows operating system Check OMPC status If the installer process is stopped or server is switched off during upgrade, the upgrade fails. Follow the steps to troubleshoot the upgrade failure scenario: 1. Run wmic product where name='Dell OpenManage Power Center' get version command on the windows command line interface to get the current version OMPC. 2. If the OMPC old version is displayed, for example 3.1.0.
NOTE: In some case (Power off or killed OMPC installer program), there is still a corrupt OMPC in the Windows OS. It may not be able to uninstall by the above command and will block any new OMPC installed. In this case, you need to remove OMPC manually. 2. a. Open register table using the regedit command and search all key or value include {79427712-CD0A-4114-A571-6BCA07F2EE0A}. Remove all key or value found. b. Stop all OMPC services if they exist. c.
2. Execute below SQL to clean old database: DROP DATABASE IF EXISTS dcm_tmp and DROP DATABASE IF EXISTS dcmapp_tmp. 3. Recover other disk files. Follow the process specified in Rollback to previous OMPC version.
B Upgrade failure recovery on Linux operating system Use install.sh command in the new OMPC version package to do upgrade or install OMPC. The install.sh command detects the version of OMPC. if there is an old version installed, upgrade process is initialized. If not, then a new version is installed. NOTE: If you use rpm -U during the Dell OpenManage Power Center installation or upgrade, many warning messages will get displayed.
1. Run [InstDir]/tools/ompc-pgsql-daemon start command to start the database daemon. NOTE: If the OMPC database daemon cannot be started, it means that the OMPC upgrade has failed, see Rollback to previous OMPC version. 2. Check the database version: a. [PGSQLDRV]= postgresql-9.3-1102.jdbc4.jar if target version is above or equals to 3.1; b. [PGSQLDRV]= postgresql-8.3-603.jdbc4.jar if target version below 3.1; You can get the current database version by the DB_VERSION item in [InstDir]/dbinfor.tmp.
