ILOM 2.0 Diagnostic Tools |
The ILOM 2.0 software running on your service processor (SP) has a complete suite of diagnostic capabilities. You can view event logs, the state of the sensors on the server node, and a list of critical faults, if any.
This chapter includes the following topics:
At minimum, you need to know the IP address of the Chassis Monitoring Module (CMM). Refer to the Sun Integrated Lights Out Manager User’s Guide for a procedure to obtain the CMM IP address.
After you have obtained the IP address of the CMM, you can obtain the IP address of the SP. The next topic describes a procedure for obtaining the SP IP address through the CMM ILOM web interface. Refer to Sun Blade X6275 Server Module Installation Guide for a procedure using the ILOM CLI.
Choose one of the following methods to log in to the SP:
After you have obtained the IP address of the CMM, you can obtain the IP address of the SP. The next topic describes a procedure for obtaining the SP IP address through the CMM ILOM web interface. Refer to Chapter 3 of the Sun Blade X6275 Server Module Installation Guide for a procedure using the ILOM CLI.

For more information about using the CLI to monitor and manage the server, refer to the Integrated Lights Out Manager Administration Guide.
Your ILOM software includes the ability to diagnose faults as they occur, where faults are defined as system component failures or chassis problems, such as environmental parameters outside acceptable ranges.
ILOM reports faults for server node components that have a fault_state property. You can see which components have this property by selecting the Components tab in the System Information view (tab). Components with the fault_state property show OK or Fault in the Fault Status column of the Component Management Status table. Components that lack the fault_state property show a hyphen (-).
Chassis environmental values are not shown in the Component Management Status table although they can have a faulted status and can be listed in the Faulted Components table of the Fault Management view (tab).
Chassis faults include the following:
The following figure shows a typical list of system components. Only those that have entries other than a hyphen (-) in the Fault Status column can be reported as faults.
FIGURE 4-6 ILOM 2.0 GUI: System Information > Component Management View
There are three types of faults:
When correctable and uncorrectable faults occur, they do the following:
When you correct a component fault, you can clear it from the SP ILOM web interface System Information --> Components tab, using the Clear Faults action from the Actions drop-down list box. This also clears the fault from the Fault Management list and turns off the Service Action Required LED. Refer to the Sun Blade X6275 ILOM Supplement for a list of faults that you can clear.
Chassis faults must be cleared from the CMM, at which time they are also cleared from the SP.
Choose one of the following methods for viewing faults with ILOM:
|
1. Log in to the ILOM web interface for the server node’s SP. See one of the following:
To Log In to the SP Through the CMM ILOM Web Interface
To Log In to the SP ILOM Web Interface Directly
The interface opens to the System Information tab.
2. Select the System Information --> Fault Management tab.
The Faulted Components list appears. If there are no faults, the list contains only the entry “No Items To Display.” If there is a fault, the faulted component is listed by component name, as shown in the following figure.
FIGURE 4-7 ILOM 2.0 GUI: System Information > Component Management View
3. Click the component name to obtain more information.
A dialog box opens with more detail. The following figure shows a fault on DIMM 7 of CPU 1 on the motherboard (MB).

->
2. Type the command show /SP/faultmgmt
To list all details, use the command:
-> show /SP/faultmgmt -level all
Faults are written to the ILOM system event log. For example, an entry for a power supply fault might look like this:
Fault detected at time = Wed Jan 21 21:40:20 2009. The suspect component: /SYS/PS0 has fault.chassis.env.power.loss with probability=100. Refer to http://www.sun.com/msg/SPX86-8000-55 for details.
SPX86-8000-55 is a Knowledge Article that you can look up on www.sun.com/msg.
http://www.sun.com/msg/SPX86-8000-55 is a web page with a description of the fault, how to repair or clear it, and so forth.

ILOM’s Data Collector utility is used to create a “snapshot” of the server node that you can send to Sun Services for diagnosis. The utility collects log files, runs various commands and collects their output, and sends the data collection as a file to a user-defined location.
| Note - The purpose of the ILOM Data Collector utility is to collect data for use by Sun Services to diagnose problems. You should not run this utility unless requested to do so by Sun Services. |
Choose one of the following methods for creating a data collector snapshot:
|
1. Log in to the ILOM web interface for the server node’s SP. See one of the following:
To Log In to the SP Through the CMM ILOM Web Interface
To Log In to the SP ILOM Web Interface Directly
The interface opens to the System Information tab.
2. Select the Maintenance tab.
3. Select the Data Collector tab.
The Data Collector panel opens, as shown in the following figure.
FIGURE 4-10 ILOM 2.0 GUI: Maintenance > Service Snapshot View
You can choose a basic or extended data set. You can also choose to send only event logs. Event logs include the system event log and several others.
4. To send maximum information, choose the Full and Disable radio buttons and click the Run button.
To send minimum information, choose the Normal and Enable radio buttons and click the Run button.
5. Specify the path and filename of the file where you want the results written.
|
1. Log in to the ILOM CLI for the server node’s SP. See one of the following:
To Log In to the SP CLI Through the CMM ILOM CLI
To Log In to the SP ILOM CLI Directly
-> set /SP/diag/snapshot dataset=MODE
-> set dataset=full
normal--(default) Specifies that ILOM, operating system, and hardware information is to be collected.
full--Specifies that the maximum information is to be collected.
| Note - Because normal is the default, in most cases you do not need to set the dataset property. |
| Note - Using the full option may reset the running host. |
3. To initiate the snapshot data collection, enter:
-> set /SP/diag/snapshot dump_uri=URI
where URI specifies the target directory in the format:
protocol://username:password@host/directory
ftp://username:password@host_ip_address/data
where password is the actual administrator password for the domain.
And where the directory, data is relative to the user’s login.
|
1. Use the cd command to get to the /SP/diag/snapshot directory:
-> cd SP/diag/snapshot /SP/diag/snapshot
2. Use the show command to view the dataset property:
To Log In to the SP Through the CMM ILOM Web Interface
-> show
/SP/diag/snapshot
Targets:
Properties:
dataset = full
dump_uri = (Cannot show property)
result = (none)
Commands:
cd
set
show
