Power-On
and Cooling-Down Policies Configurable From the Server SP
System administrators can optionally set system management
policies from the server SP to control power-on and power-off policies
on boot, as well as cooling policies for system components.
All system management policies are, by default, disabled from
the Oracle ILOM SP. For property descriptions of the system management
policies that are configurable from the server SP, see the following
table.
Note -
The policies described in this section are server-specific, therefore, they can vary from
system to system. Consult the documentation provided with your server for additional policy
details.
Table 86 Configurable Server SP Power-On and Cooling-Down Policies
|
|
|
|
Auto-Power-On Host on Boot
(HOST_AUTO_POWER_ON=)
|
Disabled (default)
|Enabled
Enable this policy to automatically power on the host server
operating system at boot.
Note -
Enabling this policy automatically disables the policy for
“Set host power to last power state policy” if
enabled.
Note -
The HOST_AUTO_POWER_ON property is
not available for configuration on all
x86 and SPARC servers.
CLI Syntax for Auto-Power-On-Host on
Boot:
set /SP/policy
HOST_AUTO_POWER_ON=enabled|disabled
|
|
Set Host to Last Power State on Boot
(HOST_LAST_POWER_STATE=)
|
Disabled (default)
|Enabled
Enable this policy to set the host server power state to the last
known state at boot.
Note -
Enabling this policy automatically disables the policy for
“Auto power-on host policy” if enabled.
Note -
The HOST_LAST_POWER_STATE property is
not available for configuraion on all
x86 and SPARC servers.
CLI Syntax for Set Host to Last Power
State on Boot:
set /SP/policy
HOST_LAST_POWER_STATE=enabled|disabled
|
|
Set to Delay Host Power On
(SPARC server only)
(HOST_POWER_ON_DELAY=)
|
Disabled (default)
|Enabled
Enable this policy on an Oracle SPARC server to delay the host
operating system from powering on at boot.
CLI Syntax for Set to Delay Power
On:
set /SP/policy
HOST_POWER_ON_DELAY=enabled|disabled
|
|
Set Low Line AC Override Mode Policy (x86 server only)
(LOW_LINE_AC_OVERRIDE_MODE=)
|
Disabled (default)
|Enabled
The Low Line AC Override policy determines whether a 4-CPU system
can use low-line (110 volt) power for special testing scenarios. The
power capacity for each power supply unit (PSU) is roughly 1000
watts at low line. Since the power of a 4-CPU system can exceed 1000
watts by a large amount, enabling this setting results in a loss of
PSU redundancy.
Note -
The LOW_LINE_AC_OVERRIDE_MODE property is
not configurable on all x86 servers.
CLI Syntax for Set Low Line AC Override
Mode Policy:
set /SP/policy
LOW_LINE_AC_OVERRIDE_MODE=enabled|disabled
|
|
Set Parallel Boot (Supported on most SPARC T series servers and
SPARC 7-2 series servers)
(PARALLEL_BOOT=)
|
Enabled (default)
|Disabled
The PARALLEL_BOOT property enables the host to
boot and power on in parallel with the SP. When enabled, parallel
booting occurs if an auto-power policy (HOST_AUTO_POWER_ON or
HOST_LAST_POWER_STATE) was on or if a user presses the power button
while the SP is in the process of booting. Oracle ILOM must be
running in order to enable the host to power on in these situations.
When this property is set to disabled, the SP boots first, then the
host boots.
Note -
The PARALLEL_BOOT property is not
configurable on x86 servers or SPARC M series
servers. It is configurable on most SPARC T series servers and
the SPARC S7-2 series servers.
CLI Syntax for Parallel
Boot:
set /SP/policy
Parallel_Boot=enabled|disabled
|
|
Redirect VGA Output
(VGA_REAR_PORT=)
|
Disabled (default)
|Enabled
Note -
The VGA_REAR_PORT property is not
configurable on x86 servers or SPARC M series
servers. It is configurable on most SPARC T series servers and
the SPARC S7-2 series server.
Enable to redirect vga output to the rear port of the server.
CLI Syntax for VGA
OUTPUT:
set /SP/policy
VGA_REAR_PORT=enabled|disabled
|
|
Set Enhanced PCIe Cooling Mode (x86 server only)
(ENHANCED_PCIE_COOLING_MODE=)
|
Disabled (default)
|Enabled
Set to allow the host to poweron independently of ILOM
Enable this policy on an Oracle x86 server PCEI card systems to
satisfy cooler operating temperature requirements.
The PCIe cool-down policy mode, when enabled, directs Oracle ILOM
to lower the chassis output temperature sensor thresholds to keep
the PCIe cards operating within the required temperature range.
Note -
The ENHANCED_PCIE_COOLING_MODE property
is not configurable on all x86 servers.
CLI Syntax for Set Enhanced PCIe Cooling
Mode:
set /SP/policy
ENHANCED_PCIE_COOLING_MODE=enabled|disabled
|
|
Enable a Cooldown Period Before Host Shuts Down (SPARC server
only)
(HOST_COOLDOWN=)
|
Disabled (default)
|Enabled
Enable this property on SPARC servers to enter a cool down mode
upon powering off the host server. The cool down mode directs Oracle
ILOM to monitor certain components to ensure that they are below a
minimum temperature as to not cause harm to the user. Once the
server sub-components are below the minimum temperature, the power
is removed from the server, or the host will turn off if the process
takes longer then 4 minutes to complete.
CLI Syntax to Enable Cool Down Period
Before Host Shuts Down:
set /SP/policy
HOST_COOLDOWN=enabled|disabled
