3. To change the power status of the server, select an action from the drop-down list.

4. Click OK in the confirmation dialog to implement your selection.


9.2 Viewing Replaceable Component Information

This section describes how to view detailed information about the Sun server replaceable components, sometimes referred to as field-replaceable units (FRUs) and customer-replaceable units (CRUs).

Depending on the component you select, information about the manufacturer, component name, serial number, and part number might be displayed.

Hot-Swappable and Hot-Pluggable Components

Some components are hot-swappable, meaning that you can remove them from the system without warning or preparation.

Other components are hot-pluggable, meaning that they can be removed while the system is running, but the system must be prepared first.

Some hot-pluggable components can be prepared for removal using the Components Management page. Those components display a radio button in the left-hand column of the Component Management page (FIGURE 9-2).

Still other components require the system to be shut down before they can be removed.



Note - The data shown in FIGURE 9-2 and FIGURE 9-3 are examples only. The actual data you see might be different on your platform. For details, see your platform supplement.



1. Log in to the ILOM as administrator or operator.

2. Select System Information => Components.

The Component Management page appears.

4. To prepare a hot-pluggable component for removal, click the corresponding radio button.



Note - Most components are either hot-swappable (can be removed without preparation), or you must shut down the system to remove them. For these components, there is no radio button.



The system prepares the component for removal, then displays its status in the Ready to Remove Status column.

For a detailed list of components, see your platform supplement.


9.3 Viewing Sensors

This section describes how to view the temperature, voltage, and fan sensor readings.

The system is equipped with a number of sensors that measure voltages, temperatures, and other settings. ILOM polls the sensors and posts an event in the sensor event log (SEL) when they cross a threshold.

For details on individual sensors, see your platform supplement.

If an event crosses a threshold defined in the Alert Destinations view, it generates an alert, which is sent to the destination configured in Section 9.5, Managing Alerts.

The thresholds appear in the Sensor Readings view shown in FIGURE 9-4.



Caution - The ILOM tags all events or actions with LocalTime=GMT (or UDT). Browser clients show these events in LocalTime. This can cause apparent discrepancies in the event log. When an event occurs on the ILOM, the event log shows it in UDT, but a client would show it as local time.



1. Log in to the ILOM as administrator or operator.

2. Select System Monitoring => Sensor Readings.

The Sensor Readings page appears.



Note - The sensor displays in this section are examples. The sensor names, ranges, and functions might be different on your system. For details, see your platform supplement.





Note - If the server is powered off, many components will appear as "no reading." To power it on, see Section 9.1, Controlling Power to the Host Server.

Note - The sensors shown in FIGURE 9-4 and FIGURE 9-5 are examples only. The actual sensor names, ranges, and functions might be different on your platform. For details, see your platform supplement.




9.4 Viewing Indicator LEDs and Controlling the Locate LED

The Indicators view shows the state of the LEDs in the system.

1. Log in to the ILOM as administrator or operator.

2. Select System Monitoring => Indicators.

The Indicators display appears.

Note - The sensors shown in FIGURE 9-6 are examples only. The actual sensor names, ranges, and functions might be different on your platform. For details, see your platform supplement.



3. Use the scrollbar to view the list.

4. To toggle the state of the locate LED:

a. Click the radio button next to /SYS/LOCATE.

b. Select a state from the drop-down menu.

The states are Turn LED Off or Set LED to Fast Blink.

A dialog asks you to confirm.

c. Click OK.

The locate LED changes states, and the new state appears in the Status column.


9.5 Managing Alerts

This section describes how to view alert destinations and configure alert settings for the ILOM.

The alert management view allows you to map alert levels to destinations (IP addresses). For example, you can configure it so that all critical alerts are sent to one destination and all non-recoverable alerts are sent to another.

An alert is generated when a sensor crosses the specified threshold. For example, if you configure an alert for critical thresholds, the ILOM sends an IPMI trap to the specified destination when any sensor crosses the upper or lower critical (CT) threshold. A special criteria, informational, is reserved for system events that are not related to sensors.

The mapping between alert levels and sensors is:


TABLE 9-1 Mapping between Alerts and Sensors

Alert

Sensor

Warning

Upper non-critical, lower non-critical

Critical

Upper critical, lower critical

Non-recoverable

Upper non-recoverable, lower non-recoverable

Informational

System events not related to sensors


All alerts are IPMI PET traps, as defined in the Intelligent Platform Management Interface (IPMI) v2.0. A special criteria, informational, is reserved for system events that are not related to sensors.

Each line in the alert management view is called a "rule". Each rule identifies an alert level and sends all alerts at that level to the specified IP address.



Note - Because there are four alert levels and 15 alert rules, you can configure the system to send the same level of alert to multiple destinations.



9.5.1 Viewing Alert Destinations

Users with operator privileges can view the alert settings. Changing them requires administrator privileges.

1. Log in to the ILOM as administrator or operator

2. Select Configuration => Alert Management.

The Alert Settings page displays a list of alerts.

The alert table includes five columns:

9.5.2 Configuring an Alert

Configuring an alert requires administrator privileges.

1. Select a radio button for an alert in the table.

2. Select Edit from the drop-down menu.

The Alert dialog box appears.

FIGURE 9-8 Alert Dialog Box

3. Type the destination IP address for the alert.

4. Select an event severity from the drop-down menu.

5. Click Save.

The modified alert appears in the Alert Destinations table.


9.6 Viewing and Clearing the System Event Log

This section describes how to view and clear the system event log (SEL).

The system event log accumulates various events, including administration changes to the ILOM, software events, and warnings and alerts. It also accumulates events from the IPMI log.



Caution - The ILOM tags all events or actions with LocalTime=GMT (or UDT). Browser clients show these events in LocalTime. This can cause apparent discrepancies in the event log. When an event occurs on the ILOM, the event log shows it in UDT, but a client would show it as local time.



1. Log in to the ILOM as administrator or operator.

2. Select System Monitoring => Event Logs.

The System Event Logs page appears.

FIGURE 9-9 System Event Log Page


Graphic showing system event log page.

3. Use the Display drop-down menu to determine how many events to display.

Selecting a larger number might cause the WebGUI to respond more slowly.

The WebGUI displays the most recent events first. To see later events, select a larger number.

4. Use the scrollbar to scroll through the list.

The fields in the Event Log table are described in TABLE 9-3.


TABLE 9-3 Event Log Fields

Field

Description

Event ID

The number of the event, in sequence from number 1.

Class/Type

  • Audit/ Log - Commands that result in a configuration change. Description includes user, command, command parameters and success/fail.
  • IPMI/Log - Any event that is placed in the IPMI SEL is also put in the management log.
  • Chassis/State - For changes to the SC/SP's state. (e.g. initializing to master).
  • Chassis/Action - Category for shutdown events for server module/chassis, hot insert/removal of a FRU and reset parameters button pushed.
  • FMA/Fault - For FMA faults. Description gives time of fault as detected by FMA and suspect component.
  • FMA/Repair - For FMA repairs. Description gives component.

Severity

Critical, Major or Minor

Date/Time

The day and time the event occurred. If the Network Time Protocol (NTP) server is enabled to set the ILOM time, the ILOM clock will use Universal Coordinated Time (UTC).

Description

A description of the event.


5. To clear the event log, click Clear Event Log.

A confirmation dialog box appears.



Note - The SEL accumulates many types of events, including copies of entries that IPMI posts the IPMI log. Clearing the SEL clears all entries, including the copies of the IPMI log entries. However, clearing the SEL does NOT clear the actual IPMI log. You must use IPMI commands to view and clear the IPMI log.



6. Click OK to clear all entries in the log.

9.6.1 Interpreting the System Event Log (SEL) Time Stamps

The SEL time stamps are related to the ILOM clock settings. If the clock settings change, the change is reflected in the time stamps.

When the ILOM reboots, the ILOM clock is set to Thu Jan 1 00:00:00 UTC 1970. The ILOM reboots as a result of the following:



Note - Log event timestamps might appear different between host and client systems because of time zone adjustment.

The timestamps on events reported in the server's system event log and IPMI logs are always based on GMT/UTC. However, when you view system information from a client system using the GUI or IPMItool, the timestamps displayed are adjusted based on the time zone of the client system. Therefore, the same event can appear to have two different timestamps when viewed directly from the host and from a client system in a different time zone.



After an ILOM reboot, the ILOM clock is changed by the following:

To set the ILOM clock, see Section 6.3, Setting the ILOM Clock.


9.7 Viewing ILOM Hardware, Firmware, and IPMI Versions

This section describes how to view the ILOM hardware and firmware revisions, as well as the Intelligent Platform Management Interface (IPMI) version.

1. Log in to the ILOM as administrator or operator.

2. Select System Information => Versions.
