1. Introduction
1.1. Project/Component Working Name:
Boot configuration Service
1.2. Name of Document Author/Supplier:
Sherry Q. Moore
1.3. Date of This Document:
12/02/2008
1.3.1. Date this project was conceived:
11/01/2007
2. Project Summary
2.1. Project Description:
To provide a new service to set/change boot configuration
parameters. One application of this service will be to control
Fast Reboot behavior.
4. Technical Description:
4.1. Details:
The boot configuration service will be called
svc:/system/boot-config:default
config/fastreboot_default boolean true
config/fastreboot_onpanic boolean true
4.1.1. Service behavior
The svc:/system/boot-config:default service will apply the
configuration defined in this case by uploading the
configuration to the kernel. The service will be enabled by
default.
4.1.1.1 fastreboot_default
# svccfg -s boot-config:default setprop \
config/fastreboot_default="false"
# svccfg -s boot-config:default refresh
When set to true, reboot(1M) and init(1M) 6 would call
uadmin(2) with AD_FASTREBOOT which will bypass firmware.
4.1.1.2 fastreboot_onpanic
# svccfg -s boot-config:default setprop \
config/fastreboot_onpanic="false"
# svccfg -s boot-config:default refresh
When set to true, the system will fast reboot on panic.
4.1.2. Refresh
# svcadm refresh svc:/system/boot-config:default
will upload all the variables to the kernel.
4.2. Bug/RFE Number(s):
6768468 Introducing svc:/system/boot-config service
4.5. Interfaces:
Minor binding only.
INTERFACE COMMITMENT LEVEL COMMENT
svc:/system/boot-config committed This service requires
solaris.system.shutdown
authorization.
config/fastreboot_default committed Boolean property
config/fastreboot_onpanic committed Boolean property
AD_UPDATE_BOOT_CONFIG Project private Macro defined
in uadmin.h.
4.6. Doc Impact:
4.6.1 Man pages for reboot(1M)
-f
Fast reboot, bypassing firmware and boot loader. The new
kernel will be loaded into memory by the running kernel,
and control will be transferred to the newly loaded ker-
nel. If disk or kernel arguments are specified, they
must be specified before other boot arguments.
This option is currently available only on x86 systems.
|
Service svc:/system/boot-config:default is enabled by |
default. When fastreboot_default property is set to "true", |
"reboot" will behave as "reboot -f". |
|
See EXAMPLES for details.
4.6.2 Man pages for init(1M)
6
Stop the operating system and reboot to the state
defined by the initdefault entry in /etc/inittab.
On x86 systems, service svc:/system/boot-config:default is |
enabled by default. When the fastreboot_default property is |
set to "true", "init 6" will bypass the firmware. |
4.7. Admin/Config Impact:
With svc:/system/boot-config:default enabled, and the following
default property settings:
config/fastreboot_default boolean true
config/fastreboot_onpanic boolean true
"reboot(1M)" and "init(1M) 6" will go through the fast reboot
path. System will fast reboot on panic. If no arguments are
provided to "reboot", the default entry in menu.lst will be
used.
