In the Solaris 9 release, the following Solaris Live Upgrade new features apply to the command-line interface only.
When using Solaris Live Upgrade to upgrade or install a Web Start Flash archive, the percentage of the upgrade or install completed is reported.
The lumount command mounts all the boot environment's file systems. If you do not explicitly specify a mount point, lumount creates a mount point that uses the boot environment name, rather than a random set of numbers. This change prevents a proliferation of mount points and aids in using the luumount command.
Mount point name with a number identifier: /.alt.1234
Mount point name with the boot environment name as the identifier: /.alt.solaris8.
In this example, the boot environment name is solaris8.
The luumount command unmounts the boot environment's root file system. The luumount command now accepts a mount point as well as the boot environment name. And with the -f option, a boot environment's file system can be forcibly unmounted.
Solaris Live Upgrade's main purpose is to minimize production environment downtime while migrating to a new operating system. Some Solaris Live Upgrade operations, such as upgrading and copying file systems, can cause significant load to a system. Solaris Live Upgrade now has the tools to control scheduling priorities, which helps prevent degrading of performance on the production system. You can change the defaults in the /etc/default/lu file.
To allow long names for boot environments, Solaris Live Upgrade commands that accept a boot environment name can now associate a description of any length with that name.
