Use the Solaris Live Upgrade tool to manage system downtime
and risk when installing patches on alternate boot environments on
Solaris 9 and 10 computers.
Introduction
An alternate boot environment
of a Solaris computer is typically created by copying the entire root
file system. With Solaris Live Upgrade, patches are applied in the
duplicate boot environment, which is in an inactive state, while the
original boot environment is running. After patching is done, you
can restart your computer to use the alternate boot environment. For
more information about Solaris Live Upgrade, see the Solaris Live
Upgrade 2.0 Guide from the Oracle documentation: http://www.oracle.com/technetwork/indexes/documentation/index.html. Figure 1. Solaris Live
Upgrade overview
Solaris Live Upgrade supports patch management for Security
Patches, Recommended Patches, and Critical Patch Updates. You can
find the related Fixlets in the Patches for Solaris Live Upgrade site.
Roadmap
To use Solaris Live Upgrade, complete
the following steps:
Ensure that the inactive boot environment that you want to patch
has an BigFix client
installed. For more information, see Installing the BigFix client.
The process for patching boot environments depends on the system
environment:
If there is only one inactive boot environment on the system,
proceed with patching. For more information about patching, see Patching using Fixlets. Then, proceed to step 5.
If there are several inactive boot environments, you must select
one boot environment for live upgrade from the Manage Solaris Boot
Environments dashboard. For more information about this task, see Selecting inactive boot environments for Live Upgrade.
