Managing the ILOM Using the WebGUI

This chapter describes how to use the WebGUI to perform monitoring and maintenance.

It includes the following sections:


7.1 Configuring the Serial Port

This section describes how to configure the ILOM serial port. Use this procedure only when you need to change the serial port settings. The default settings are 9600 baud and no flow control.

The serial port provides access to the WebGUI, the command-line interface (CLI), and the system console stream using serial port redirection.



Note - Normally, the console matches the ILOM's default settings (9600 baud, 8N1 [eight data bits, no parity, one stop bit], no flow control).



1. Log in to the ILOM as administrator.

2. Select Configuration => Serial Port.

The Serial Port Settings page appears.

3. Select the baud rate for the internal serial port from the Internal Serial Port drop-down menu.

This setting must match the setting for serial port 0, COM1 or /dev/ttyS0 on the host operating system.

The baud rate value must match the speed that was specified for the BIOS serial redirection feature (default is 9600 baud) and the speed used for the boot loader and operating system configuration.

To connect to the system console using the ILOM, the ILOM must be set to its default settings (9600 baud, 8N1 [eight data bits, no parity, one stop bit], no flow control).

4. Select the baud rate for the external serial port from the External Serial Port drop-down menu.

This setting must match the baud rate on the RJ-45 serial port on the Sun server.

5. Click Save for your changes to take effect, or click Cancel to return to the previous settings.


7.2 Configuring ILOM Network Settings

This section describes how to configure the network parameters for the ILOM.

The ILOM automatically configures its IP settings using the Dynamic Host Configuration Protocol (DHCP). If your network does not support this protocol, you need to set the parameters manually.

1. Log in to the ILOM as administrator.

2. Select Configuration => Network.

The Network Settings page appears.

Description

MAC Address

The ILOM's MAC address is set at the factory. The MAC address is a hardware address that is unique to each networked device. The ILOM's MAC address is provided on a label on the ILOM, on the Customer Information Sheet included on the ship kit, and in the BIOS Setup screen.

Configuration Method

Select one of the following radio buttons to configure the ILOM's IP address either dynamically or statically.

  • Obtain an IP Address Automatically (Use DHCP) - Enables a DHCP server to configure the ILOM's IP address dynamically.
  • Use the Following IP Address - Enables you to configure the ILOM's IP address with a static IP. The IP Address, Subnet Mask, and Default Gateway fields will become editable when you select this option.

IP Address

Type the ILOM's IP address. The IP address is a unique name that identifies the system on a TCP/IP network.

Subnet Mask

Type the subnet mask of the network on which the ILOM resides.

Default Gateway

Type the ILOM's gateway access address.


4. Click Save for your settings to take effect.



Note - Changing the IP address ends your ILOM session.
Settings are considered pending until you click Save.



You are prompted to close your web browser.

5. Log back in to the ILOM using the new IP address.



Note - If you changed the network settings, you must log back in with a new browser session.




7.3 Setting the ILOM Clock

This section describes how to set the ILOM clock manually or to synchronize the ILOM date and time with a Network Time Protocol (NTP) server.

The ILOM clock is described in Section 7.3.3, Interpreting ILOM Clock Settings.

Before you begin, obtain IP addresses of the NTP servers you want to use.

7.3.1 Setting the ILOM Clock Manually

1. Log in to the ILOM as administrator.

2. Select Configuration => Clock Settings.

The Clock Settings page appears.

2. Select Configuration => Clock Settings.

The Clock Settings page appears. See FIGURE 7-3.

3. Select the Enable check box next to Synchronize Time Using NTP.

4. Type the IP addresses of the NTP servers you want to use.

5. Click Save for your changes to take effect.

7.3.3 Interpreting ILOM Clock Settings

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:


7.4 Resetting the ILOM

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

2. Select Maintenance => Reset SP.

The Reset Service Processor page appears.

FIGURE 7-4 Reset Service Processor Page

3. Click Reset SP to reset the ILOM.

The ILOM reboots. The WebGUI is unavailable while the ILOM reboots.


7.5 Resetting the ILOM and BIOS Passwords

This procedure causes the ILOM to reset the administration password and clear the BIOS password.

This procedure requires changing a hardware jumper in your server enclosure. See your service manual for details.


7.6 Upgrading the ILOM Firmware

Both the ILOM and BIOS firmware are tightly coupled and are always updated together. A single firmware image contains both the ILOM and BIOS firmware.

Occasionally, you might need to downgrade your firmware. Downgrading is done exactly the same as upgrading, only you choose an older (downgraded) image in Step 7.



Caution - Ensure that you have reliable power before upgrading your firmware. If power to the system fails (for example, if the wall socket power fails or the system is unplugged) during the firmware update procedure, the ILOM could be left in an unbootable state.

Do not proceed until you have reliable power.





Caution - Shut down your host operating system before proceeding. Otherwise the ILOM will shut the host down ungracefully, which could cause file system corruption.





Note - The upgrade takes about five minutes to complete. During this time, no other tasks can be performed in the ILOM.

To observe the status of the upgrade while it's happening, set the session timeout to 3 hours. See Section 7.9, Setting the ILOM Session Timeout Period for details.



1. Log in to the ILOM as administrator.

2. Ensure that you can access the new flash image on the client machine that you are using to update the ILOM.

3. If the server OS is running, perform a clean shutdown.

4. Select Maintenance => Firmware Upgrade.

The Upgrade the Firmware page appears.



Caution - Do not close the WebGUI using the Log Out button in the web browser when the ILOM is in Upgrade mode. If you must close the WebGUI, use the WebGUI's Cancel button.

8. Click Upload.

The Upgrade wizard copies the selected file into the ILOM's DRAM, and then verifies that the copy procedure was successful. This takes about one minute with a fast network connection.

The system displays a confirmation dialog box.



Note - A network failure during the file upload will result in a time out and the ILOM will reboot with the prior version of the ILOM firmware.



9. Click OK.

The Verify Firmware Image page appears.

FIGURE 7-7 Verify Firmware Image Page


Graphic showing Verify Firmware Image dialog.

10. Select Preserve Configuration to keep your ILOM settings. Otherwise, they will be overwritten.

11. Click Start Upgrade, or click Cancel to stop the upgrade.



Note - If you choose to cancel the firmware upgrade operation, the ILOM will reboot without the updated software. You must close the web browser and log back in to the WebGUI before you can perform any other type of operation.



If you clicked Start Update, a progress screen indicates that the firmware image is being upgraded. Once the upgrade progress reaches 100%, the firmware upgrade is complete.

After the upgrade operation has completed successfully, the ILOM will automatically reboot. This is done so that the image upgrade can take effect.

A screen prompt might ask you to repeat the upgrade. This is not due to any problem. If this happens, repeat the procedure, starting at Step 1.



Note - You cannot perform any other operation within your current web browser session.



12. Close your web browser and reconnect to the ILOM.



Note - If the configuration is not preserved, enter BIOS setup and save the optimal default settings.




7.7 Enabling HTTP or HTTPS Web Access

This section describes how to view and modify web server settings.

ILOM provides the option to control access to the web interface. There are four choices:

HTTPS is enabled by default.

1. Log in to the ILOM as administrator.

3. Select the HTTP or HTTPS web server.

The HTTPS web server is enabled by default.



Note - If you disable HTTP or select Redirect HTTP Connection to HTTPs, and then disable HTTPS, you will be unable to access the WebGUI. To restore access, use the CLI /SP/services/http or https commands, as described in Section 6.7, Enabling HTTP or HTTPS Web Access.



4. Assign an HTTP or HTTPS port number.

5. Click Save to save your settings.


7.8 Uploading a New SSL Certificate

This section describes how to upload a Secure Sockets Layer (SSL) certificate and SSL private key to use when accessing the ILOM.

To establish a secure HTTPS connection to the ILOM, you must upload an SSL certificate and a private key into the ILOM. These two together help provide a secure connection to the correct server when using HTTPS. Ensure that the uploaded SSL certificate and private key match. If they do not match, secure access may not work properly.

1. Log in to the ILOM as administrator.

2. Select Configuration => System Management Access => SSL Certificate.

The SSL Certificate Upload page appears.

FIGURE 7-9 SSL Certificate Upload Page

3. Type the file name of the new SSL certificate, or click Browse to search for a new SSL certificate.

The file name has a .pem file extension. The ILOM does not support pass-phrase encrypted certificates.

4. Click Upload to upload the selected SSL certificate.

The SSL Certificate Upload Status dialog appears.

5. Once you have uploaded the certificate and private key, click OK to reset the ILOM immediately, or click Cancel to reset the ILOM later.

The ILOM must be reset for the new certificate to take effect. If you click OK, you must close your web browser and reconnect to the ILOM. HTTPS is enabled by default.

You can now access the ILOM securely, using the following format in your IP Address field from your web browser:

https://<ILOM IP address>

For example, if the ILOM's IP address is 192.168.0.30, type the following:

https://192.168.0.30



Note - Ensure that you include the "s" after http.




7.9 Setting the ILOM Session Timeout Period
