Log in with Single Sign-on (SSO)
SSO uses centralized authentication servers that other applications and
systems utilize for authentication purposes, and combines this with
techniques to ensure that users do not actively have to enter their credentials
more than once.
Kerberos SSO requires specific domain environment settings for the
Windows Active Directory (AD) domain controller, Power Center server, and
Web browser.
Single Domain Environment
The following illustration shows how to set up a single domain environment
with the following components:
•
Domain Controller — dns.dcm.dell.com is the Windows AD server that
supports domain dcm.dell.com (Father and Child).
•
Power Center Server — server1.dcm.dell.com is the server with Power
Center installed.
•
Power Center Client — server2.dcm.dell.com is the client server that
connects to the Power Center server.
To set up the Kerberos SSO single domain environment, perform the
following steps:
Step 1. Install Power Center
When installing Power Center:
1 Set up a Realm Name. You must enter a Fully Qualified Domain Name
(FQDN) of the Realm. For example, dcm.dell.com.
Access Control
35
OpenManagePowerCenter_User_Guide.book
Page 36 Friday, March 2, 2012
10:33 AM
2 Set up AD domain controller addresses. Separate multiple addresses with a
comma. For example, 192.168.0.250.
3 Specify a domain user for dcm.dell.com as Power Center server’s domain
account for Kerberos SSO. This user account must be an existing and valid
domain user account. For example, "Tom" and Tom’s password.
Step 2. Set up Service Principle Name (SPN) for Power Center service in
AD Domain Controller
1 Log into the AD domain controller as an Administrator.
2 Open a command console.
3 Add two SPNs for Power Center, use server FQDN in one SPN and server
NetBIOS name for the other SPN. The user account associated with
service SPN must be the Power Center server’s domain account for
Kerberos SSO configured during Power Center installation or in the
Settings page. For example:
setspn -a HTTP/server1.dcm.dell.com Tom
setspn -a HTTP/server1 Tom
Step 3. Configure Web browser
You must configure your Web browser to support SSO. For more information
on how to configure this, see your Web browser Help. For a list of supported
Web browsers, see "System Requirements" in the "Overview" chapter.
NOTE: To correctly set up Kerberos SSO: 1) The date and time on all involved
computers must be consistent. 2) DNS configuration must be correct.
To support SSO in Firefox, you must send Kerberos credentials to the
appropriate KDC.
To support SSO in Internet Explorer, you must add the Power Center server
as a local Intranet site.
The following is an example of configuration steps in Microsoft Internet
Explorer 8:
1 Go to Internet Explorer 8 → Internet Options → Security → Local
Intranet, and click Sites. The Local Intranet window opens.
2 Click Advanced, add your Power Center site into Local Intranet. For
example, server1.dcm.dell.com.

Multiple Domain Environment
The following illustration shows how to set up a multiple domain
environment with the following components:
•
Domain Controller — There are several Windows AD domain controllers
in the illustration, including the parent domain dcm.dell.com and the
child domans east.dcm.dell.com and west.dcm.dell.com.
•
Power Center Server — server1.east.dcm.dell.com is the server with Power
Center installed. It is an AD domain controller, the domain name is
east.dcm.dell.com。
•
Power Center Client — test.west.dcm.dell.com is the client server that
connects to the network of the Power Center server.
To set up the Kerberos SSO multiple domain environment, perform the
following steps:
Step 1. Install Power Center
When installing Power Center, do the following:
1 Set up the Default Realm Name of the domain in which Power Center is
installed. You must enter FQDN. For example, east.dcm.dell.com.
2 Set up the AD Domain Controller addresses. Separate multiple addresses
with a comma. For example, 192.168.0.2, 192.168.0.3.
3 Specify a domain user for east.dcm.dell.com as Power Center server’s
domain account for Kerberos SSO. For example, "Jerry" and Jerry’s
password.
Step 2. Set up SPN for Power Center service
Access Control
37
OpenManagePowerCenter_User_Guide.book
Page 38 Friday, March 2, 2012
10:33 AM
Set up SPN for Power Center service in all involved AD domain controllers. In
the example, three domains are involved: dcm.dell.com, east.dcm.dell.com
and west.dcm.dell.com. Repeat the following steps on each domain.
1 Log into the AD domain controller as an Administrator.
2 Open a command console.
3 Add two SPNs for Power Center:
•
If it is on the Default Realm (configured in Step 1), the user account
associated with the service SPN must be the Power Center server’s
domain account for Kerberos SSO configured in Step 1. For example,
setspn -a HTTP/server1.east.dcm.dell.com Jerry
setspn -a HTTP/server1 Jerry
•
If it is not on the Default Realm, for example, it is on dcm.dell.com,
the user account associated with the service SPN must be a domain
user account in the current domain. For example, Jack is a domain
user in dcm.dell.com. Use the following commands to create service
SPN on the dcm.dell.com domain controller.
setspn -a HTTP/server1.east.dcm.dell.com Jack
setspn -a HTTP/server1 Jack
Step 3. Configure Web browser
You must configure your Web browser to support SSO. For more information
on the configuration, see step 3 of "Single Domain Environment" in this
chapter.
Windows NT LAN Manager (NTLM) Authentication Limitation
Power Center supports Kerberos SSO for Windows domain user
authentication. To enable this feature, Power Center is configured to support
the Windows integrated authentication option which includes two
authentication mechanisms: Kerberos and NTLM .
NTLM is not supported in Power Center. If the client’s Web browser uses
NTLM to authenticate domain users for Power Center, there are some
limitations.
Access Control
38
OpenManagePowerCenter_User_Guide.book
Page 39 Friday, March 2, 2012
10:33 AM
What's the limitation?
The Web browser displays a message box requiring a Windows user name and
password:
•
If you press OK after entering a user name and password, whether the
information is correct or not, the Power Center login page appears and
requires you to authenticate through the login page.
•
If you press Cancel, there is an HTTP Status 401 failure and you cannot
log into Power Center.
When does this occur?
When one of the following elements of Kerberos SSO is not correctly
configured: Power Center server, Web browser or AD domain controller
configuration.
How to solve?
Correctly configure your Power Center server, AD controller and Web browser
for Kerberos SSO. For more information on how to configure, see the section
above and your Web browser Help.
Multiple User Login
Power Center supports up to ten concurrent user login instances. When
multiple users log into Power Center, if one user implements a change in Power
Center, for example, deleting a device or moving a device, this may cause
unexpected behavior for other logged in users. For example:

Device Discovery
To manage devices in Power Center, you must add the devices to the Power
Center management console first. You can add devices by discovering devices
from the network, or adding devices manually.
This chapter explains how to discover devices from the network and add
devices manually in the Power Center management console.
Power Center device discovery includes both the automatic detection of all
devices on your data center and the collection of basic information about
each device, such as the device name, connection status, device type, device
model, its IP address and hostname, and the protocol it uses for
communication. This enables you to track the device status and your data
center information. You can also manage these discovered devices in Power
Center. If there is a new or changed device in your data center, you can use
the device discovery function to rediscover the devices.
You must have the "Manage Device/Group" and "Discover Device" privileges
to add a device to Power Center.
There are two scenarios for adding devices:
•
Add a device from the network — You can discover a device from the
network. The discovered devices will be automatically added to the Device
List.
•
Add a device manually — You can use the Power Center management
console to specify device properties and add a device to the Device List.
NOTE: If you use a network security policy, the discovery function may not work
properly.
Supported Devices and Unsupported Devices
You can add or discover supported devices, and create a group structure to
build out the data center. Power Center cannot discover or manage all device
types, and unsupported devices must be added manually to make the data
center group structure complete.
For supported devices:
Device Discovery
51
OpenManagePowerCenter_User_Guide.book
Page 52 Friday, March 2, 2012
10:33 AM
•
Device types include server, UPS, PDU and chassis.
•
Set the connection protocol and credential information so that the device
can communicate with Power Center.
•
Add or discover a supported device to the Device List. Perform
management functions including discovery, adding to the group
structure, monitoring power and temperature, applying power
management policies, and sending events.
For unsupported devices:
•
Power Center does not communicate with unsupported devices, therefore
connection protocol and credential information is not necessary.
•
Unsupported devices cannot be discovered, only added manually to the
Device List.
•
Power Center adds the unsupported device to the group structure, but
cannot manage it using the available management functions.
You may need to enter the following power values when adding supported or
unsupported devices:
•
Faceplate Power: The maximum amount of power that a group/device
can draw; this value should be listed on the power supply specifications.
The faceplate power rating is typically much higher than the actual
power used by the device.
•
De-rated Power: The default maximum power value; if a power
measurement cannot be completed, this value is used.
NOTE: Faceplate power value is always greater than the de-rated power
value.
Adding a Device from the Network
This section explains how to use the Power Center management console to
discover a device from the network.
Before adding a device from the network, make sure the DNS server is set up
correctly. Specifically, make sure that:
•
There is a DNS server running on the Power Center’s network.
•
The specified DNS server has a reverse DNS zone for the network on
which you are trying to discover the devices.
Device Discovery
52
OpenManagePowerCenter_User_Guide.book
Page 53 Friday, March 2, 2012
10:33 AM
NOTE: Power Center server tries to get device names from the DNS server
specified in the network configuration of the operating system. This may cause the
device name to be different from the actual one if the DNS server resolves the
device IP address to a different device name.
To discover devices from the network, complete the following steps:
Step 1. Enter IP Range
1 Go to the Discovery page.
2 Enter the IP address range, or select one in the list. If the correct range is
not displayed, add it using the following steps:
3 Click Add IP Range, and enter information in the following fields:
•
Beginning — The beginning IP address. For example, 192.168.1.1.
•
End — The end IP address. For example, 192.168.1.255.
•
Network Mask — The network mask. For example, 255.255.255.0.
4 Click Apply. The new IP range is added to the list of IP ranges and
displayed at top of the page.
5 Select at least one IP Range, and click Next.
NOTE: The IP Ranges section lists not only the IP ranges that you have added, but
also the IP ranges of the recent three discovery tasks.
Step 2. Select Protocol
You can either create a new protocol profile or use an existing protocol profile.
To create a new protocol profile:
1 Click Add Protocol.
Enter information in the following fields:
•
Profile Name — Enter the profile name. The profile name must be
less than 16 characters.
•
Description — Enter the description for this profile.

Group Management
You can configure several devices as a group so that you can manage them.
Power Center enables you to create and organize your devices into two
distinct types of groups:
•
Physical Group
A physical group is a group of groups/devices with a structure mapping that
represents the actual physical layout.
For more information on how to create and manage physical groups, see
the "Physical Groups" chapter.
•
Logical Group
A logical group is a collection of groups and devices with a logical relation.
A logical group does not need to map with the actual physical layout.
For more information on how to create and manage logical groups, see the
"Logical Groups" chapter.
Mapping Group Structure Information
Power Center supports group stucture mapping for Dell PowerEdge rack
servers and tower servers. For more information on the specific models, see

Physical Groups
A physical group is a group of groups/devices with a structure mapping that
represents the actual physical layout.
As an IT/facility administrator, you may need to organize devices and groups
according to their physical layout in the data center. Power Center enables
you to monitor power/temperature information, manage policies/events at
individual device, chassis, rack, aisle, room or data center levels.
Data Center Physical Group
Power Center manages physical groups with the following group structure:
Data Center → Room → Aisle → Rack → Chassis. You must create physical
groups in this order.
PDU, UPS and unsupported devices can be attached at any level of the
physical group structure. You can find the PDU and UPS devices information
at the bottom of the group’s page.
You can manually create physical groups, then add devices into the groups
through the management console.
Creating Physical Group
To create a physical group:
1 Go to Group Management → Physical Groups, and click Select a
Physical Group.
2 Click Add New.
3 Enter a Name and Description for the data center.
4 You can create multiple groups at once if you click Add New <Entity
Name> in the Tasks section. Click Duplicate Group and enter the
Number of the groups to create. Power Center automatically names the
groups by adding a number (starting from 1) to it. For example, if you
enter the name GroupA and number 10, Power Center creates ten groups
named GroupA1, GroupA2 ...GroupA10.

NOTE: Power Center can read the power consumption of a device when it is at S0
(On) state. For devices in S4/S5 state, Power Center uses a fixed value (30W) to
calculate the power consumption.
•
Cooling Energy — The estimated energy consumption and cost needed to
cool the selected device/group.
Cooling Energy = IT Equipment Energy * Cooling Multiplier
You can configure the cooling multiplier in the Settings → Energy
Consumption page.
•
Energy Consumed (Total) — The combined energy consumption and
costs for the IT equipment and cooling energy. The calculation 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. The rate is a global setting, and can be set on the Settings → Energy
Consumption page.
NOTE: The Energy Consumption section displays information based on the values
configured in the Settings page. This information should be used as an estimate
only.
NOTE: When a device or group is newly added or created in Power Center, the
power and energy consumption data displayed in the "1W" and "1M" time windows
are different if the monitored time is less than 1 week, and the data displayed in the
"1H" and "1D" time windows are different if the monitored time is less than 1 day. This
occurs because Power Center uses different sampling intervals for different time
windows. For example, a device is added into Power Center at 2011-10-15 09:00, and
the current time is 2011-10-17 11:10. For the 1M time window (sampling interval is 1
day), the power and energy consumption is calculated from 2011-09-17 00:00 to
2011-10-17 00:00. For the 1W time window (sampling time is 1 hour), the power and
energy consumption is calculated from 2011-10-10 11:00 to 2011-10-17 11:00. There
is a 11 hour gap therefore the data displayed in the two time windows are not the
same.

Temperature Monitoring
Power Center enables monitoring of the current or historical temperature of
the data centers in Power Center. It 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.
Temperature Monitoring Level
Power Center provides temperature monitoring at the following levels:
•
Device level:
You can monitor temperature-related metrics for devices.
•
Physical group level:
You can monitor temperature-related metrics at the physical group level
(data center, room, aisle, chassis modular)
•
Logical group level:
You can monitor temperature-related metrics at the logical group level.
Temperature Monitoring Configuration
You can configure temperature monitoring settings in Power Center,
including:
•
Thresholds (Inlet temperature range for events)
•
Device and group range (Monitor all or not)
•
Sampling interval (1, 3, or 6 minutes)
•

Power Policies
A power policy is a set of configurations used to manage the power cap for
devices or groups. A policy is useful for defining power management in
different situations, for example:
•
You can set up a policy to make sure that the power consumption does not
exceed the capacity of the circuit.
•
You can set up a policy with a scheduled time 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.
•
You can set up a policy to increase the rack density. For example, you
currently have ten devices in rack A_01 that is monitored by Power Center.
By monitoring the power consumption from the Power Details page, you
can estimate how many devices you can add to rack A_01. You can set up a
policy to cap the total power consumption of rack A_01 after you added
the devices.
Power Center supports two policy types:
•
Static power policy — The power cap for each device is defined by you,
and will not be changed unless you redefine it. A static power policy
enables you to set a power cap for each device in the group. You can create
a static power policy for a rack, chassis or device.
•
Dynamic power policy — The power cap for each device is dynamically
allocated by Power Center when necessary, based on the power
consumption information and other power information on each device.
Power Center evaluates power consumption for each device in every
monitoring cycle to decide the necessity of changing the power cap for
each device. A dynamic power policy enables you to allocate the power
dynamically for each device in the group while maintaining the power cap
for the group. A dynamic power policy has less performance impact to a
device/group compared with a static power policy. You can create a
dynamic power policy for a logical group, data center, room, aisle, rack, or
chassis.
Power Policies
95
OpenManagePowerCenter_User_Guide.book
Page 96 Friday, March 2, 2012
10:33 AM
How Does a Dynamic Power Policy Work?
To understand how a dynamic policy works, you need to understand the
following terms first:
•
Consumption — The 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 top priority of the dynamic power policy is to maintain the power cap of
the group. Maintaining this cap means that all devices can execute their
workloads without needing more power than the cap. The priority of the
device may not be taken into account when allocating power cap to a group of
devices if most, or the entire power cap is allocated towards maintaining the
power cap on each of the devices in the policy; if lower priority devices require
more power to maintain their cap, they may actually receive more power than
a higher-priority device. If the power cap is too restrictive and the group
power consumption exceeds the power cap, an event is sent for the power
policy. You need to reconsider the power allocation or adjust workloads when
a power policy is consistently violated by one or more devices exceeding their
power cap.
If fluctuations in device power requirements happen once the power cap is
successfully established for all devices in a power policy, a device requiring
more power may not get it as the power cap of another device in the policy
could become violated as it is lowered. If you wish to force one or more
devices in a policy to a lower cap, you can create a static power policy for the
device at a lower level. In this case, the most restrictive power cap of the
overlapping policies is applied to the device.
If there is excess available power from the power cap (known as headroom)
after the power capping requirements is met for all devices in the policy, then
this excess power can be allocated dynamically according to the priority and
demand of the device in the power policy.
Power Policies
96
OpenManagePowerCenter_User_Guide.book
Page 97 Friday, March 2, 2012
10:33 AM
If the average power consumption of a device becomes lower than the power
cap established for the device, its power cap is evaluated and adjusted in each
monitoring cycle, and the excess power is deemed as headroom for other
devices to consume.
Power Policy Capabilities
Power Center defines the following statuses of power policy capabilities for
the devices:
•
Unknown — Shown for unsupported devices or devices that were never
connected to Power Center.
•
None — No power policy capability. You cannot set any policy on the
device.
•
Monitor — With power monitoring capability only.
•
Monitor & Capping — With power monitoring and capping capabilities.
•
Monitor and Upgradable — With power monitoring capability, and can be
upgraded to have power capping capability.
You can find this power policy capability status in the Power Capability
column of the Device List page.
For servers that comply with Dell iDRAC7, when there is a power policy
capability change due to a license change, Power Center will change its
information in the management console within 24 hours. There are two
scenarios:
Scenario 1. The license expires or is not imported
In this case, the following happens:
•
If a policy exists on the devices, you will receive a "Server Capabilities
Changed" event.
•
The Policy tab of the devices is set to disabled in the Power Overview
page.
•
The power capability status of the devices is set to "None" in the Device
List page.
•
You cannot edit the policy of this device from the Policies page; you only
can delete it.
Power Policies
97
OpenManagePowerCenter_User_Guide.book
Page 98 Friday, March 2, 2012
10:33 AM
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.
•
The Policy tab of the devices is set to Enabled in the Power Overview
page.
•
The power capability status of the devices is changed in the Device List
page.
•
The policy of the devices is editable. You can access it from the Policies
page.
Upgrading Device Power Policy Capability
The power policy capability of some devices can be upgraded to include
capping of power consumption, for example, Dell PowerEdge M620. These
devices show Monitor and Upgradable. To upgrade the device so that its
power consumption can be capped, go to the Device List page and click
Upgrade next to the device, then follow the instructions on the pop-up help
page to upgrade the device power capability. Once the upgrade is completed,
the power capability status changes to Monitor & Capping within 24 hours.
Creating a Policy
You can create static or dynamic policies for your device/group.
You can create static power policies for a rack, chassis or device, and create
dynamic power policies for any group/device. Power policies only apply to the
groups/devices that have Monitor & Capping power capability.
You can create multiple policies on the same device/group. This is useful
when you want to apply different policies at different time periods for the
same device/group.
To create a new policy:
1 Go to Power Overview → Physical/Logical Groups page.
2 Click the rack/chassis/device icon, and go to the Policies tab.
3 Click Create New Policy.

the devices that have Monitor & Capping power capability.
d
Enter Power Cap Value or Percentage of Capability for the
group/device:
•
Power cap value: Enter a value between the Lower Bound and Upper
Bound. The Lower Bound is the lowest minimum power consumption
since the device/group was either discovered/added. The Upper Bound
is the maximum power consumption when the device/group is in a
maximum workload state. You cannot enter a power cap value lower
than the Lower Bound value. This value is the total power
consumption budget for devices that have Monitor & Capping power
capability.
•
Percentage of capability: Enter a percentage (1%-100%) of the Upper
Bound value to set the power cap.
The "Power Cap Value" and "Percentage of Capability" are related values.
The following formula describes the relationship between the two values:
Upper Bound * Percentage of Capability= Power Cap Value
e
Click Next.
NOTE: The default power cap unit is Watts. You can change this to a different unit.
For more information on how to change the default unit, see "Default Units Settings"
in the "Configuring Power Center" chapter.

reserves more of the power for the devices/groups with a higher priority when the
power cap is not completely utilized.
•
For a static policy, Power Center uses the same percentage of the Upper
Bound value as the power cap for each device by default. You can enter a
different value (Power Cap Value or Percentage of Capability), and click
Next.
NOTE: If the sum of the entered device power cap is higher than the power cap value
set in the previous step, Power Center will change the Power Cap Value and display a
message prompt.

data on a regular basis to avoid such impacts. To restore the policies after Power
Center is corrupted, perform the following steps: 1) Reinstall Power Center. 2) Use
the backup data to recover. After completing the two steps, you can use the
previously-existing policies to control the devices. For more information on Power
Center data backup and recovery, see the "Backup and Recovery" chapter.
Viewing Policy Details
You can view policies from the following pages:
•
Policy page — This page lists all policies. You cannot create a policy on
this page. You can edit, delete, sort, filter or enable/disable the policies.
•
Power Overview → Policy page — This page lists policies for a specific
entity. To view the policies, go to the Power Overview page, select a
physical group or logical group, select an entity and click its Policies tab.
You can create, edit, delete, sort, or enable/disable the policies on this
page.
These two pages display policy details:
•
Enabled — The policy is enabled or disabled.
•
Active — The policy is in use or not in use.
•
Entity Name — Name of the entity.
•
Policy Name — Name of the policy.
•
Type — Static power policy or dynamic power policy.
•
Power Cap — Power cap for the entity.
•
Date Range — Start date and end date for the policy to take effect.
•
Time Range — Time of the day for the policy to take effect.
•
Days — Day of the week for the policy to take effect.
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.
Power Policies
101
OpenManagePowerCenter_User_Guide.book
Page 102
Friday, March 2, 2012
10:33 AM
For each device/group, you can set one of the three priority levels:
•
Low
•
Medium (Default)
•
High
Priority lists are policy-specific; however a device/group may have different
priority levels in different policies. A higher-priority 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 <A, B, C> and Policy2 for device
<B, C, D>, and you configured different priorities or power caps for the
policy with the same time slot. In this case, Power Center follows these rules:
•
If there are overlapping policies on an entity, the policy with the lowest
power cap is applied.
•
If there are overlapping dynamic policies on an entity and both are
currently active, the highest priority (High > Medium > Low) of this
entity is applied.
Policy Modes
The policy mode is shown in the Enabled and Active columns in the Policies
page. A green symbol indicates Enabled or Active. Power Center supports
three policy modes:

Event Management
This chapter provides information on event types, severity levels, supported
PDU/UPS events, and how to manage the events in Power Center.
You can receive events indicating an abnormal power/temperature situation in
the data center.
Power Center detects these types of events:
•
Pre-defined events
•
Custom events
The internal event listening port of Power Center is 6553; Power Center uses
this port to receive events from Power Center internal. If an application uses
port 6553, make sure to change it and reserve this port for Power Center.
The default external event listening port is 162; Power Center uses this port
to receive events from the external devices. If the SNMP Trap service exists
and uses port 162, Power Center automatically uses port 1162 to receive the
external events forwarded by the SNMP Trap service.
Pre-defined Events
A pre-defined event is an event that Power Center defines based on system
conditions. Power Center defines the following events (A-Z) at different severity
levels.
Table 14-1.

check the policy on the device.
NOTE: To receive events from a PDU or UPS, you must subscribe to the event from
the console of that PDU/UPS.
NOTE: For the Power Center supported IPMI events (IPMI Power Unit, IPMI Power
Supply, IPMI Processor Temperature Trip, IPMI Fan), Dell PowerEdge tower servers
and rack servers support all these IPMI events, and Dell PowerEdge blade servers
only support IPMI Processor Temperature Trip events.
NOTE: Power Center only supports IPMI trap format for Dell iDRAC devices. To
receive events from a Dell iDRAC device, make sure the alert function is enabled
and the IPMI trap format is selected for all the Power Center-supported events
(IPMI Power Unit, IPMI Power Supply, IPMI Processor Temperature Trip, IPMI Fan)
in the iDRAC management console. For example, in the Dell iDRAC7 management
console, you must select IPMI trap for all PWR/PSU/CPU/Fan-related alerts. For
more information on how to use the Dell iDRAC management console, see Dell
iDRAC Help.

Security
Power Center is designed to ensure data confidentiality, data integrity and the
security of user authentication. Power Center not only provides
authentication and access control to user accounts (see the "Access Conrol"
chapter), but also protects all the communication channels to the Power
Center server, and the stored sensitive data (for example, passwords ) on
Power Center server.
See the following guideline and facilities to enhance the security for your
Power Cener system:
•
Starting services with a normal Windows operating system (OS) user
account: After installing Power Center, the Power Center services are
logged on with the Network Service account by default. You can use a
normal Windows OS user account instead of the Network Service
account. The Windows OS user account provides better security.
•
OS hardening: You can deploy OS hardening on the OS where Power
Center is installed. By doing so, the minimum security foundation is set up
for Power Center security-related configurations.
•
Audit log: Power Center tracks the action log for critical user operations,
including user login/logout, emergency power reduction, start/stop
network discovery, security configuration and policy change.
•
Certificate management: Power Center enables SSL/TLS communication
between the Power Center management console and the Power Center
server, and the communication between the Power Center server and
chassis, to enforce the confidentiality and data integrity of the
communication. The SSL/TLS authentication is certificate-based. Power
Center uses a keystore file to manage the certificates.
Starting Services with a Normal Windows OS
User Account
To configure a normal Windows OS user account, follow these steps:
1 Stop all Power Center services.

The total size of all audit log files is limited to 20MB; they are evenly split
into three log files (approximately 6.67MB each). If a new log causes the file
size to exceed the limitation for a single log file, Power Center renames the
log file to a new name, and stores the new log in a new log file with the
original file name.
When generating an audit log file, the naming rule is as follows:
•
audit.log — The first audit log file name. This file always logs the latest
actions.
•
audit.log.1 — The second audit log file name. This is copied from
audit.log when it exceeds the file size limitation.
•
audit.log.2 — The third audit log file name. This is copied from audit.log.1
when audit.log exceeds the file size limitation.
Power Center keeps up to three audit log files. When the three files exist and
audit.log exceeds the file size limitation, audit.log.1 overwrites audit.log.2,
and audit.log overwrites audit.log.1.
Managing Certificates
Power Center uses Keytool to generate a key pair (a public key and an
associated private key); it wraps the public key into a self-signed certificate
during the installation.
Keytool is a key and certificate management utility from Java Runtime
Environment, it is located at <InstallDir>\external\jre\bin\keytool.exe. The
private key and the self-signed certificate are stored in the keystore file at
<InstallDir>\keystore.ssl. The self-signed certificate expires three months
after installation. It is strongly recommended to update the private key and
self-signed certificate within three months.
You can manage Power Center certificates through the Keytool. Possible
common scenarios include:
•
Scenario 1 — Generate a key pair and self-signed certificate
During the installation of Power Center, a key pair and self-signed
certificate are generated for the Power Center server.
NOTE: When you delete an entry from the keystore file, make sure you leave at
least one key pair entry in the keystore file; otherwise, Power Center will not work.

Scenario 2 — Replace the self-signed certificate with a signed certificate
issued by a Certification Authority (CA)
A certificate signed by a CA is more likely to be trusted by the Web
browsers. To sign your certificate by a CA, do the following:
•
–
Generate a Certificate Signing Request (CSR) and submit to the CA.
–
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, or the exposed management interface
through WS-MAN) or web service providers may provide a certificate for
Power Center validation during the communication establishment. 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, the
communication will fail. In this scenario, you may need to import a new
trust certificate to make sure a trust path can be built to verify the
certificate.
For more information on how to manage certificates, see Keytool Help.

Database Policy Settings
These settings are used to configure the database maintenance policy.
Power Center stores the monitoring data of your data center in the database
file. Power center uses compressed power/temperature data to optimize for
higher query performance and smallest database size.
Power Center stores both power/temperature compressed data and noncompressed data in the database. Data Compression will aggregate and save
the monitoring data using a bigger granularity (hourly or daily), but not the
original granularity decided by the Sampling Interval. Data Compression
helps to improve the efficiency of data queries.
Power Center keeps compressed power/temperature data and event data up to
365 days and non-compressed power/temperature data up to 14 days.
Configure the length of time that Power Center will keep compressed and
non-compressed data using the Purge Data Older Than and Data
Compression fields. The data that exceeds its length of time or is older than
the purge date is deleted. This improves the efficiency of the data query. You
can automatically purge data by using the Schedule Database Purging Daily
at field, or you can trigger it manually to start purging data immediately (see
the task "To purge the database now").
You can set the following for database maintenance:

keep the compressed data and the event logs. The default is 365 days.
•
Schedule Database Purging Daily at — You can set the time of day to
start database purging (00:00:00 - 23:00:00). The default is 23:00:00.
•
Export Database — You can export the data in a selected date range to a
.csv file. Click Export Database, and define a start and end date to export
all the data between 00:00:00 of the start date to 00:00:00 of the next day
after the end date to a .csv file. By default, the .csv file is saved in the
Downloads folder of your Web browser.
The following data is exported:
–
Measurement data of supported devices (excludes groups) — There is
no measurement data for unsupported devices.
–
Hourly data — Hourly data is the data collected during the hour
before (timestamp - 1). For example, if the timestamp of the data is
14:00:00, the "PowerAvg" field displays the average power from
13:00:00 to 14:00:00.
NOTE: If there is no data available at the defined timestamp, this field displays
"-1".
The .csv file includes the following fields:
–
DeviceId — Power Center internal device unique ID.
–
DeviceType — Device type. For example, Server, PDU, UPS and
CMC.
–
DeviceName — Device name.
–
DeviceIP — Device IP address.

3 Recover all Power Center data files.
a
Refer to your operating system documentation for instructions on how
to change file privileges; you need to add your OS user with the Read
and Write privileges for the files listed in the Power Center Data table.
NOTE: Record your actions, because these privileges will be removed later.
b
Local: Replace all of the Power Center data files above with your
backup files except server.xml and java.security. Remote: Replace all of
the Power Center data files above with your backup files except
server.xml and java.security and pgdata folder. Follow the PostgreSQL
backup and recovery Web page to recover the remote database. (For
both local and remote: for best results, rename these files for backup,
and copy backup files to this location).
c
For server.xml, you must manually update its parameters with the
parameters in the original server.xml backup file.
1) Update SSL port:
Replace the following highlighted value with the value in the
server.xml backup file.
<Connector port="8688" protocol="HTTP/1.1"
server="localhost" maxHttpHeaderSize="8192"
connectionTimeout="60000" xpoweredBy="false"
allowTrace="false" scheme="http" redirectPort=

For java.security, you must manually update the login.config.url.1
parameter with value file:${java.home}/lib/security/login.conf. For
example:
login.config.url.1=file:${java.home}/lib/security/login.conf
e
Refer to your operating system documentation for instructions on how
to remove file privileges, you need to remove the privileges that you
have added for the files.
NOTE: Make sure the account that Power Center services is logged on with
the Full Control privilege to the Power Center data files (see "Power Center
Data" section in this chapter). Otherwise, the recovery may fail. For example, if
Power Center services are logged on with the Network Service (default)
account, and this account has no Full Control privilege to the recovered
pgdata folder, the Dell OpenManage Power Center Database Server service
will not start and the recovery will fail.
4 Start all Power Center services.
The Power Center recovery is completed.
NOTE: When you change the Read/Write privileges for the files listed in the Power
Center Data table, to make sure the success of backup or recovery, double-check
the privileges before proceeding to the next step.

Troubleshooting
This chapter lists some of the known issues you may encounter when working
with Power Center, and some possible solutions.
•
•
•
•
Problem1: Not able to access the Power Center management console from
the client browser, even though the Power Center server is running
normally.
–
Cause: The proxy setting may prevent the browser from accessing
the Power Center server on the network.
–
Resolution: Check your proxy setting and make sure it is properly
configured.
Problem 2: Cannot play video when clicking the video links in the Getting
Started page.
–
Cause: You do not have a flash player installed for your Web browser.
–
Resolution: Install the latest version of Adobe Flash Player for your
Web browser.
Problem 3 You have been logged out of Power Center automatically.
–
Cause: Possible causes include: 1) The network connection is lost. 2)
Your user account has been deleted.
–
Resolution: 1) Check your network connection status; make sure it is
connected to the Power Center server. 2) Check your user account
status; make sure it is not deleted by another user with higher
privileges.
Problem 4: The network connection status is connected, but you failed to
connect to Dell iDRAC6 devices (Dell PowerEdge Servers).
–
Cause: Dell iDRAC6 devices are limited to three concurrent
connection sessions; you have reached the limitation of connection
sessions. 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.

Resolution: Wait one minute or more for Dell iDRAC6 devices to
release the connection sessions, then try again.
Problem 5: Power Center cannot receive events sent from devices.
–
Cause: Possible causes include: 1) Power Center is not the destination
host of the events sent from devices. 2) There is a network connection
problem. 3) The essential services are not started.
–
Resolution: Make sure that: 1) The Power Center server’s IP address is
registered on the device as the destination for the events. 2) The
network of the device and the Power Center server is connected and
packets can be routed to each other. 3) If the Windows SNMP Trap
service is installed on the Power Center server, this service and the
Dell OpenManage Power Center SNMP Dispatcher shall be started on
the Power Center server.
Problem 6: If Power Center uses a remote database during the installation,
the error message "server side error has occurred, please contact support"
displays when you launch the Power Center management console.
–
Cause: The connection between Power Center and the remote
database server is lost because the IP or hostname of the remote
database server has been changed.
–
Resolution: 1) Change the IP or hostname of the remote database to
the previous value. 2) Update the Power Center configuration files
with the new database server address. Perform the following steps
(These steps assume that Power Center is installed at
C:\Program\Files. If Power Center is installed at a different location,
substitute the correct location.): a) Assign the current OS user with
Read and Write privileges to the configuration files "app.config.xml"
and "user.config.xml" located at C:\Program
Files\Dell\OpenManagePowerCenter\conf\. b) Open the two files
with a text editor. c) Change the DB_SERVER_NAME value to a new
database server IP or hostname. d) Remove the privileges that you
assigned to the configuration files in Step a. e) Restart all the Power
Center services and launch the Power Center management console
again.
Problem 7: The Firefox Web browser crashes when it has been running for
a long time.

–
Cause: Firefox may have a memory leak after running for a long time.
The memory leak-related issues may cause Firefox to function
improperly.
–
Resolution: Restart the Firefox Web browser and log into Power
Center again.
Problem 8: Cannot see the Power/Temperature data in the Dashboard tab.
–
Cause: You may have changed the settings of the Power/Temperature
sampling intervals. Before the new settings take effect, the
Power/Temperature data may be temporarily unavailable.
–
Resolution: Wait until the new settings take effect. For more
information on when the settings are effective, see "Monitoring
Settings" in the "Configuring" chapter.
Problem 9: Power Center is corrupted or uninstalled, but the previouslyexisting power policies (including EPR) on the devices are still effective.
–
Cause: Even if Power Center is corrupted or uninstalled, the Power
Cap Values of the existing power policies (including EPR) on the
devices still remain effective.
–
Resolution: Check your data center power capacity to avoid tripping
the breaker before performing the following steps. 1) If you uninstall
Power Center, make sure you have removed all devices before
uninstalling. 2) If Power Center is corrupted, do one of the following
to remove the power policies: 2.1) If the device number is small, access
the Dell iDRAC management console, and manually remove the
power policies. 2.2) If the device number is large, perform the
following steps: a) Install Power Center. b) Add all the devices to the
Power Center management console. c) Create a logical group that
contains all these devices, then create any power policy for this group.
d) Remove all these devices from the Power Center management
console. After completing the steps a-d, Power Center will remove the
policies first, then remove the devices.
Problem 10: A PostgreSQL error log "FATAL: terminating connection due
to administrator command" occurred in the Windows event log.
–
Cause: This is caused by Power Center server shutdown. Normally the
Power Center database service (Dell OpenManage Power Center
Database Server service) will stop after other Power Center services,
but if the Power Center server has been shut down quickly, the Power

Center database service will be forced to stop when other Power
Center services are not yet stopped yet. In this case, the database
connection sessions that cannot be closed by other Power Center
services will be closed by the Power Center database service, and this
error is generated. Since such an error is caused by Windows when it
shuts down the services quickly, Power Center will protect its
important data through transaction; therefore, this kind of error does
not impact Power Center.
–
Resolution: No action is required.
