11.1 Introduction to Managing Hardware Assets

Oracle Enterprise Manager Ops Center provides comprehensive lifecycle management for the hardware assets in your data center. The hardware assets can be handled individually or as a group. After the discovery and management of the hardware assets, as described in Asset Management, you can configure and then monitor them to gather the information to maintain them.

11.1.1 Configuring Hardware Assets

Use these deployment plans:

Install Server
Update BIOS Configuration
Configure Service Processor
Configure Server Hardware and Install OS
Configure RAID
Configure M-Series Hardware, Create and Install Domain
Configure and Install Dynamic System Domain

All the plans are based on hardware resource profiles. See Hardware Resource Profiles

11.1.2 Monitoring Hardware Assets

As soon as a hardware asset is managed, Oracle Enterprise Manager Ops Center starts to monitor it, according to the asset type's monitoring profile. The center pane displays information for a selected asset in a series of tabbed windows. The tabs and the type of information is specific for the asset type but, in general, Oracle Enterprise Manager Ops Center reports the following:

Health status
Power state
Power usage
Hardware variables and connectivity

You can change the monitoring thresholds in the standard profile to specify the conditions that generate an alert. You can also create custom profiles with different rule sets and alert parameters and apply the profile to a specific system, a group of homogeneous systems, or a group that you define.

For more information about monitoring policies and rules, see Chapter 4.

For information about monitoring power consumption, see Energy Tab.

11.5 Profiles for Hardware Management

The work flow of an asset deployment can be captured and enacted in a repeatable fashion using plans and the profiles included in the plans. Oracle Enterprise Manager Ops Center provides default profiles for configuring hardware asset types consistently. You can use the default profiles, make copies of the profile to edit, or create new ones.

Deployment proceeds from configuring the hardware, installing the correct firmware, provisioning the OS, and applying the required updates. The deployment is not only for servers with an OS installed but also for chassis, racks, power distribution units, and M-Series servers.

11.5.1 Hardware Resource Profiles

Use hardware resource profiles in a deployment plan to configure, install, or update systems. The Oracle Enterprise Manager Ops Center software provides the following hardware resource profiles:

Configuring the Service Processor
Configuring a RAID Controller
Configuring a Dynamic System Domain
Configuring a Rack and Placing Components

You can use the default profiles, make copies of the profile to edit, or create new ones. Use the profiles in a deployment plan to configure your hardware assets.

11.5.2 Firmware Provisioning Profiles

Hardware depends on firmware to perform operations. Part of monitoring and managing a hardware asset is to make sure that it has the appropriate version of firmware. Oracle Enterprise Manager Ops Center uses firmware profiles to provision, or update, firmware on each type of asset.

A firmware profile is a set of actions and values that define how to provision one or more assets and specifies one or more firmware images. A firmware profile updates existing firmware assets completely and consistently. When you apply a deployment plan that contains a firmware profile, Oracle Enterprise Manager Ops Center compares the versions of each firmware image specified in the profile with the versions of the existing firmware on the asset and then takes the action you specify in the profile.

See Firmware Compliance Reports and Firmware Provisioning.

11.6 Configuring the Service Processor

The Declare Unconfigured Asset action includes the service processor in the Oracle Enterprise Manager Ops Center environment. You can configure only unconfigured service processors, that is, a processor in its factory default state. Use a deployment plan to configure the service processor:

Configure Service Processor
Update BIOS Configuration
Configure and Deploy Server
Install Server

An alternative to specifying the configuration in the profile, is to duplicate an existing configuration. You can create a snapshot of the BIOS of a working service processor, which creates also creates profile. You then apply the profile to an unconfigured service processor.

11.6.1 Creating a Service Processor Configuration Profile and Plan

Expand Plans in the Navigation pane and the select Profiles and Policies.
Expand Service Processors.

Expand Assets in the Navigation pane and then select Servers.
Select the unconfigured server.
Click Update Service Processor in the Action pane. A one-step wizard is displayed, including the list of snapshots in the EC local library that are appropriate for the selected server.
Select the snapshot from the list.
Click Next to review the Summary and then click Finish to submit the job.

When the service processor is configured, the server reboots.

Apply a Service Processor Snapshot Profile to a Server

Expand Plans in the Navigation pane and then select Profiles.
Expand Update BIOS Configuration and select the profile for the snapshot.
Review the profile in the center pane. To modify the profile, click the Edit Profile icon.
Create a plan that includes this profile as its only step or edit an existing deployment plan to include this profile.

11.7 Configuring a RAID Controller

Oracle Enterprise Manager Ops Center provides a default profile for configuring RAID controllers. You can configure and update the hardware devices that can be done only through the host OS. This profile provisions a reduced OS image along with the management pack on the target to configure RAID.

Caution:

When you reconfigure an existing RAID controller, all the data on the disk is lost.

11.8 Configuring a Dynamic System Domain

You can create domains on a M-series server.

Verify that a user account with platadm privilege exists on the XSCF processor and is included in the profile. Disable the audit policy for this user account, using the following command:
```
setaudit -a opsadm=disable
```
Verify that you can use ssh to log in to the XSCF processor.

To configure a Dynamic System Domain, you apply a deployment plan to an M-Series server, as described in Chapter 8. The plan includes the profile for the Dynamic System Domain.

11.9 Configuring a Rack and Placing Components

The rack asset is a group that includes the other managed assets installed in the physical rack, such as servers or compute nodes, storage arrays or appliances, switches, and power distribution units (PDU). After you create the rack, you put assets in the rack so that Oracle Enterprise Manager Ops Center can present them and manage them as if it were a physical asset.

You have the option to place assets into the rack immediately after this procedure ends or to perform this task at a later time.
Enter a description for this rack.
Add semantic tags that are appropriate for this rack.
Click Create Rack to submit the job.

Placing Assets in a Rack

The rack asset is a group that includes the managed assets installed in the physical rack, such as servers or compute nodes, storage arrays or appliances, switches, and power distribution units (PDU).

Use the Place/Remove Assets in Rack action and the Place/Remove PDU in Rack action to specify each asset in the physical rack and its location in the rack so that Oracle Enterprise Manager Ops Center can represent the physical rack accurately to users who cannot examine the rack. Update the type and location of the assets in the rack asset when the configuration of the physical rack changes.

Placing a Power Distribution Unit in a Rack

Expand Assets in the Navigation pane and select Racks from the Resource Management Views.
Select the rack.
Click Place/Remove Assets in Rack in the Actions pane or click the Details tab to navigate to the icon. The Place Assets in name Rack window opens, which displays a list of all managed assets in the physical rack. You can filter the list by type or attribute.
Click an asset and then enter its slot number.
Click Place Asset in Rack. The Assets in the Rack pane is updated to show the location.
Continue to select assets and place them in the rack.
To change an asset's slot, select it and click Edit Placement. Enter a new slot number.
To remove an asset, select it and click Remove Asset. The asset is deleted from the Assets in the Rack pane and is available to be placed.
When you are satisfied with the configuration displayed in the Assets in the Rack pane, click Submit.

To add PDUs to the rack asset, use the Place/Remove PDUs action in the same way. Select the rack and the action. The assets you have placed in the rack are shown in the Assets in Rack pane. Add each PDU.

11.10 Hardware Monitoring

The Oracle Hardware Management Agents use Simple Network Management Protocol (SNMP) to monitor your Oracle hardware and storage devices. The software uses the Intelligent Platform Management Interface (IPMI) protocol to accesses the Oracle ILOM service processors.

A monitoring policy is a set of rules applied to an asset. If a status changes or a threshold is crossed, an alert is created. Oracle Enterprise Manager Ops Center provides default policies for each asset type. You can create new policies or modify existing policies.

11.10.1 Hardware Status

If a hardware asset can report a value for a hardware variable, Oracle Enterprise Manager Ops Center reports its current state and compares it to the threshold value.

Good – The hardware asset is working properly.
Unknown – Oracle Enterprise Manager Ops Center is unable to retrieve information from the sensor. The hardware asset is connected but is not reporting information.
Unreachable – The hardware asset cannot be contacted. This state indicates a network problem.
Warning Failure – Oracle Enterprise Manager Ops Center has detected a potential or impending fault condition. Take action to prevent the problem.
Critical Failure – A fault condition has occurred. Take corrective action.
Nonrecoverable Failure – The hardware asset has failed. Recovery is not possible.
Faulted – The hardware asset reports a fault. Contact service personnel to repair.

11.10.2 Groups of Hardware Assets

Oracle Enterprise Manager Ops Center monitors hardware assets according to the monitoring profile for that type of asset. To see the default profile for monitoring a hardware type, see Hardware Monitoring.

To change a threshold value, see Editing Monitoring Rules in Chapter 4.

11.11 Monitoring Power Utilization

Input power is the power pulled into a power supply from an external resource. The power consumption of a hardware asset is the sum of the input power consumed by each power supply of the asset. Output power is the amount of power provided from the power supply to the system components, measured at the power supply output. Input power is calculated from output power by applying an efficiency function to the output power from each power supply.

Calculating power compensation for the blades is difficult because the power supplies are shared. Each blade gives a report based on the power consumption of the local components, but this is not an accurate power consumption value for an individual blade.

To measure the input power, the interfaces must be exposed and the service processors must be able to retrieve and report data with one-minute accuracy. Servers that can report power usage have a Charts tab.

You can see current power usage and change the display of power graphs using the controls on the Energy tab and the Charts tab.

11.11.1 Energy Tab

The asset's Energy tab reports power consumption as the current value and for a period of time, as well as attributes of the fan and power supplies. The current values are reported for the following attributes:

Wattage
System Load for an OS
Utilization Per Cent for an Oracle VM Server for SPARC
Incoming air temperature and outgoing air temperature
Power Policy
Cost Per KiloWatthour
Currency units used to compute cost. The price per currency unit is set by the Edit Energy Cost action in the Administration section of the Navigation pane. See the Oracle Enterprise Manager Ops Center Administration Guide for information.
Total Power Cost for one day

The data over time is represented in the following graphs:

Power Consumption and Utilization: By default, the graph shows the power consumed in the last day in watts. If the server is shut down, the graph shows any existing historical data.
Temperature and Fan Speed: By default, the graph shows the incoming air temperature and the outgoing air temperature in Celsius, and the average fan speed in RPM. Click any point on the graph to see that data for that point in time.

By default, the graphs are in Live mode, which reports new information every five seconds. Click the Live button in the graph's toolbar to make the information static so that you can set the period of the graphs to one of the following:

One hour (1H) – One point for every five minutes
One day (1D) – One point for every five minutes
Five days (5D) – One point for every five minutes
Three weeks (3W) – One point every hour
Six weeks (6W) – One point every 12 hours
Six months (6M) – One point for every day

To make a graph with the minimum of two points, a hardware asset must have been managed for at least 10 minutes to view a one-hour graph and for at least two days to view the six-months graph.

The data for these time periods is stored separately. For example, if a server has been managed for two hours and you select the 6W view, the graph cannot be displayed because only one point of data of that type has been stored; the second point has not yet occurred. If you then select the 1D view, the graph can display 24 points of data (120 minutes at 5-minute intervals). However, the graph displays these points over a 24-hour period and not over the actual two-hour period. For the most accurate representation of the data, choose a time period that is less than or equal to the time that the hardware asset has been managed.

You can export the data for either the current view or all available data to a file in either CSV or XML format. Use the Export Chart Data toolbar icon to choose options for exporting the data.

If the graph is blank, one of the following conditions has occurred:

The server does not have the appropriate ILOM version.
The server has not been discovered through the ILOM driver.
The server is unreachable.

11.11.2 Charts Tab

The Chart tab provides more ways to display the power utilization data. You can change the graphed data to a bar chart or an area chart. You can also export the data for either the current view or all available data to a file in either CSV or XML format. Use the Export Chart Data button to choose options for exporting the data.

For groups and virtual pools, the following options are available:

Select Order: The five highest or five lowest historical power utilization.
Select Resource: Select the Power or Aggregate Power option for a homogeneous or heterogeneous group of servers.
- The Power option displays power utilization for the five highest or lowest power consumers in the group or virtual pool.
- The Aggregate Power option displays the power utilization, using the sum of all members that report power consumption. The number of systems in the aggregate is included. For heterogeneous group, the Chart tab includes a table of all systems in the group and their various power attributes for the selected time period. From this table, you can power off and power on selected servers to conserve power.

11.12.3 Installing and Upgrading Oracle Solaris Cluster

You use cluster profiles in a deployment plan to perform the following operations:

Install Oracle Solaris Cluster software
Upgrade Oracle Solaris Cluster software

See Appendix B for instructions on obtaining the current profiles and supporting scripts.

11.13 Firmware Provisioning

The Oracle Enterprise Manager Ops Center provisioning feature installs firmware on the managed hardware assets, using the protocols and ports listed in Table 7-6. You initiate the installations from the UI, rather than from the asset itself.

Oracle Enterprise Manager Ops Center provides default profiles for configuring firmware for servers and for disk storage. An alternate procedure is to create a Firmware Report. You then use the report results to update the firmware.

Note:

The Update Firmware and Firmware Reports actions are disabled for Exalogic systems, except for its storage resource, the Sun ZFS Storage Appliance.

The benefit of using a profile to install firmware is that the firmware is installed consistently, no matter how many assets you provision. The benefit of using the Firmware Compliance Report is to identify the firmware on a specific asset or set of assets.

11.13.1 Firmware Profiles

The general procedure for provisioning firmware has the following steps:

Import a file with the firmware and the associated metadata into a software library, according to the procedure in Keeping Your Firmware Up-to-Date in the How To library at http://docs.oracle.com/cd/E27363_01/nav/howto.htm.
Create a firmware profile, based on one or more firmware images, according to the procedures in Keeping Your Firmware Up-to-Date in the How To Library at http://docs.oracle.com/cd/E27363_01/nav/howto.htm.
Shut down the server gracefully. Most firmware requires that the server is not running when the firmware is updated. Most firmware images include a power-off command for a running server, which causes a hard shutdown of the server.
Apply the firmware profile.

11.13.2 Firmware Compliance Reports

The Firmware Report feature compares the firmware images specified in a firmware profile to the firmware images installed on one or more hardware assets. Use the Make Targets Compliant button in the Interactive type of report to update the firmware on any non-compliant assets.

The report shows whether a target asset is compliant, not compliant, or not applicable:

A compliant asset has the firmware images specified in the profile.
A non-compliant asset does not have the same firmware images as specified in the profile. Update the firmware by either clicking the Make Targets Compliant button in the Interactive report or using the procedure in Updating Firmware.
A non-applicable asset indicates that a firmware image in the profile does not match the model of service processor in the asset. This condition can occur when either the profile does not recognize the model of the service processor or the profile includes firmware images that are not designed for the service processor.
1. Compare the model of the service processor displayed in the asset's Summary tab with the model of the service processor included in the profile. If they are different, add the name in the profile to the asset's data.
2. When the firmware profile was created, only images that matched the service processor could be included. However, if the service processor did not report all the firmware types it supported, an image that did not match the service processor could have been included in the profile. To update the Oracle Enterprise Manager Ops Center software with all the service processor's supported firmware types, use the Refresh action. When the job is completed, view the service processor's Summary tab to see all firmware types.
3. Create a new firmware compliance report.

See Creating a Firmware Report for the procedure to create the report.

11.13.3 Updating Firmware

To update the firmware on one or many assets, you use a deployment plan to apply a firmware profile for the type of asset. For a server, the profile updates the firmware on a service processor, and restarts the service processor and operating system. For storage components, profiles update firmware on a RAID controller, an expander, or disk.

To see the deployment plans that update firmware, expand the Deployment Plans section of the Navigation pane and then click Firmware. A list of existing plans and profiles is displayed.

To update the firmware of one asset, an alternative to a deployment plan is to use the Update Firmware action. Select the asset from the Asset section of the Navigation pane and then click Update Firmware in the Actions pane.

Before You Begin

The software library must contain the images that provision the firmware. Perform the Uploading a Firmware Image procedure in the Keeping Your Firmware Up-to-Date document in the How To library at http://docs.oracle.com/cd/E27363_01/nav/howto.htm.

If you are updating the firmware on a server, shut down the server before you update the firmware. A firmware update to a server's service processor usually requires that the server is not running. If you start to update the firmware on a running server's service processor, the procedure performs a hard shutdown of the server.

Requirements for ALOM Service Processors and M-Series Servers

The firmware provisioning process for M-Series servers and servers that have ALOM service processors relies on a temporary account that performs an FTP operation.

Note:

Advanced Lights Out Management (ALOM) is a Sun Microsystems standard for these systems: SunFire V125/V210/V215/V240/V245/V250/V440/T1000 and Sun Netra 210/240/440.

If your site does not allow a temporary account, use the following procedure to prepare for the provisioning operation:

On the Enterprise Controller, open the /var/opt/sun/xvm/hal.properties in an editor.

Add the following properties to the file:

ftp.user.name=username
ftp.user.password=password

Restrict access to the file to root user:

chmod 600 /var/opt/sun/xvm/hal.properties

On the Proxy Controller that provisions the firmware, enable the ftp service on Oracle Solaris or the vsftpd service for Oracle Linux systems.

You can now apply the firmware provisioning deployment plan. The FTP operation retrieves the credentials from the file.

If a network failure occurs while updating the firmware, repeat the firmware update procedure. If you do not repeat the procedure, the firmware inventory list might be incomplete.

Option for Deferring the Stop and Restart of the Operating System and Server

The procedure is available for Oracle Solaris 10 Update 10 operating systems running on servers with the ILOM x86 (3.0 and higher) service processor.

When you update the firmware of a service processor, the procedure stops the operating system and the server before the update and restarts them after the update so that the new BIOS takes effect. If you prefer to stop and restart at a convenient time, keeping the current BIOS in effect, use the following procedure to change the action of both Oracle Enterprise Manager Ops Center and the firmware's metadata:

On the Enterprise Controller, open the /var/opt/sun/xvm/hal.properties in an editor.
Add the following property to the file:
```
ilom.fwp.skipAutoReboot=true 
```
On the Proxy Controller that provisions the firmware, enable the ftp service on Oracle Solaris or the vsftpd service for Oracle Linux systems.
At a later time, reboot the servers.
