Before You Begin

To control the power state of the remote host server, you need the Admin (a) role enabled.

Control Power State of Remote Host Server Using Server SP Web

1. Log in to the ILOM SP web interface.

2. Click the Remote Power Control tab.

The Server Power Control page appears.

3. From the Server Power Control page, you can remotely control the power state of a host server by selecting one of the following options from the Action menu:

Reset - This option immediately reboots the remote host server.

Immediate Power Off - This option immediately turns off the power on the remote host server.

Graceful Shutdown and Power Off - This option shuts down the OS gracefully prior to powering off the remote host server.

Power On (default) - This option turns on full power to the remote host server.

Power Cycle - This option immediately turns off the power on the remote host server, then applies full power to the remote host server.

Control Power State of Remote Chassis Using the CMM Web Interface

1. Log in to the CMM ILOM web interface.

2. Click the Remote Power Control tab.

The Server Power Control page appears.

3. From the CMM Remote Power Control page, you can remotely control the power state of the chassis and its system components by selecting the radio button next to /CH (Chassis) or /CH/BL# (individual blade slot #) then selecting one of the following options from the Action menu:

Immediate Power Off - This option immediately turns off the power to the chassis components, including the blades.

Graceful Shutdown and Power Off - This option attempts to bring the OSs down gracefully on the blades, then cuts power to the system components.

Power On - This option gives full power to the chassis and blades, subject to system policies.

Power Cycle - This option powers off the blade, then automatically powers the system back on (not applicable to /CH).

Managing Host Control of BIOS Boot Device on x86 Systems

Before You Begin

The Reset and Host Control (r) role is required to change the host boot device configuration variable.

The Host Control -BIOS boot device feature is supported on x86 system SPs. This feature is not supported on the CMM or on SPARC system SPs. For information about ILOM Host Control boot options on SPARC systems, consult the online ILOM Supplement guide or Platform Administration guide published for that system.

Follow the steps in the following procedure to override the BIOS boot device setting from ILOM by using the Host Control features.

Configure BIOS Host Boot Device Override

1. Log in to ILOM SP web interface.

2. Click Remote Control --> Host Control.

The Host Control page appears.

Host Control Page

3. In the Host Control page, click the Next Boot Device list box and specify a boot device option.

Possible boot device options available:

default - Setting the value to default means that there is no override to the BIOS settings. Setting to default will also clear any previously chosen selection.

pxe - Setting the value to pxe means that at the next host boot, the BIOS boot order settings will be temporarily bypassed and instead the host will boot from the network, following the PXE boot specification.

disk - Setting the value to disk means that at the next host boot, the BIOS boot order settings will be temporarily bypassed and instead the host will boot from the first disk as determined by BIOS. The specific disk chosen depends on configuration. Typically, hosts use this option by default and the host's behavior might not change by selecting this option.

diagnostic - Setting the value to diagnostic means that at the next host boot, the BIOS boot order settings will be temporarily bypassed and instead the host will boot into the diagnostic partition, if configured.

cdrom - Setting the value to cdrom means that at the next host boot, the BIOS boot order settings will be temporarily bypassed and instead the host will boot from the attached CD-ROM or DVD device.

bios - Setting the value to bios means that at the next host boot, the BIOS boot order settings will be temporarily bypassed and instead the host will boot into the BIOS Setup screen.

4. Click Save for your changes to take effect.
