Overriding
SPARC Host Boot Mode
Oracle ILOM provides a set of host boot mode properties that
enables system administrators to override the default method for
booting the host operating system on the SPARC server.
The host boot mode properties in Oracle ILOM are intended
to help resolve corrupt boot mode settings with OpenBoot or LDoms.
The boot mode properties, when set in Oracle ILOM, apply only to
a single boot and expire within 10 minutes if the power on the host
SPARC server is not reset.
System administrators can use the Oracle ILOM CLI or web interface
to set the host boot mode properties. For more details about these
properties, see the following table.

|
|
|
|
State
(state=) |
Normal |
Normal | Reset
NVRAM
Set to instruct Oracle ILOM to which action to take when the
power on the SPARC server is reset.
CLI Syntax to Set Host Boot Mode State:
For single-server
SP, type:
set /HOST/bootmode state=normal|reset_nvram For multi-domain server SP, type:
set
/Servers/PDomains/PDomain_n/HOST/bootmode
state=normal|reset_nvram
|
Expiration Date
(expires=) |
No value, read-only property |
Bootmode properties expire
within 10 minutes or when the power on the SPARC server resets (which ever
comes first).
The LDOM Config and Script properties do not expire and are
cleared upon the next server reset or when the values are manually
cleared.
CLI Syntax to View Host Boot Mode Expiration Date:
For single-server
SP, type:
show /HOST/bootmode expires For multi-domain server SP, type:
show
/Servers/PDomains/PDomain_n/HOST/bootmode
expires
|
Script
(script=) |
|
Up to 64 bytes in length.
The script controls the host SPARC server OpenBoot PROM firmware
method for booting.
The script is read when: (1) the State is set to Reset NVRAM,
(2) power on the SPARC server is reset, and (3) OpenBoot variables
are reset to defaults.
Note - Service personnel might instruct you to specify a script
for problem resolution. The full extent of script capabilities is
not documented and exist primarily for debugging. CLI Syntax to Set Host Boot Mode Script:
set /HOST/bootmode script=value
Where:
script does not affect the current /HOST/bootmode setting.
value can be up to 64 bytes in length. You can specify a /HOST/bootmode
setting and specify the script within the same command. For example:
set /HOST/bootmode state=reset_nvram script=”setenv diag-switch? true” |
LDOM Config
(config=) |
Factory-default |
Factory-default | Valid
LDOM Config
Instruct Oracle ILOM which LDOM configuration to use upon
resetting the power on host SPARC server:
Factory-default – The
factory-default configuration is the initial configuration where the
platform appears as a single system hosting only one operating system.
Use the factory-default configuration in Oracle ILOM to regain
access to all system resources (CPUs, memory, I/O) that might have
been assigned to other domains. The Factory-default property value
might be necessary if you removed the Logical Domains Manager before restoring
factory defaults using the Logical Domains OS software. Valid LDOM Config – Enter the name of a
valid active logical domain configuration.
CLI Syntax for Host Boot Mode LDOM
Config:
set /HOST/bootmode config=factory-default|valid_LDOM_configuration |
