2. Project Summary
2.1. Project Description:
Provides a new attribute in Boot configuration service to permit
boot-archive updates during uadmin(2) operations.
Patch/micro-release binding requested.
3. Business Summary
3.1. Problem Area:
Some customers require the use of uadmin(2) to reboot which can
result in boot archive inconsistency on reboot since uadmin(2)
does not update the boot archive,
Other applications such as clustering require that uadmin(2)
NOT update the archive, so always updating the archive cannot
be made the default.
3.2. Market/Requester:
Lucent Technologies
4. Technical Description:
4.1. Details:
Introduce a new property, 'uadmin_boot_archive_sync', to config
group in svc:/system/boot-config:default service.
The default value of this property is
config/uadmin_boot_archive_sync boolean false
uadmin(2) system call will respect this property setting when
determining whether to update boot-archive before rebooting.
Customer may set this value to true if they want to
reboot/halt/shutdown the system using uadmin interface
and ensure that the boot archive remains in sync.
4.2. Bug/RFE Number(s):
6795430 newboot needs a fully supported way to automatically recover
when boot archive is out of date
4.6. Doc Impact:
Some additions required to Basic Administration guide, uadmin (2)
and uadmin(1M) man pages to describe the new property introduced
and how to make use of this property to update the boot-archive.
4.6.1 Man page of uadmin(2) and uadmin(1M)
Shutting down or rebooting or halting the system by means of uadmin
does not update the boot archive by default. To update the boot archive
during these operations, set the uadmin_boot_archive_sync property
of boot-config service to true.
# svccfg -s svc:/system/boot-config:default setprop \
config/uadmin_boot_archive_sync="true"
4.8 Interfaces:
svc:/system/boot-config committed per PSARC/2008/760
config/uadmin_boot_archive_sync committed boolean property
4.12. Dependencies:
PSARC/2008/760 Boot configuration Service.
Solaris 10 doesn't have this project integrated. This project
introduces the boot-config service (but not fast reboot itself)
portion of PSARC/2008/760.
