Solaris 10 Installation Guide: Network-Based Installations

Installing and Upgrading When Using Non-Global Zones

When the Solaris OS is installed, the software group installed in the global zone is the set of packages that is shared by all the non-global zones. For example, if you install the Entire software group, all zones contain these packages. By default, any additional packages installed in the global zone also populate the non-global zones. You can segregate into non-global zones any applications, namespaces, servers, and network connections such as NFS and DHCP as well as other software. Each non-global zone is unaware of other non-global zones and each can operate independently. For example, you might have installed the Entire software group on the global zone and have running on separate non-global zones the Java Enterprise System Messaging Server, a database, DHCP, and a web server. When installing non-global zones remember the performance requirements of the applications running in each non-global zone.

Caution – Caution –

A Solaris Flash archive cannot be properly created when a non-global zone is installed. The Solaris Flash feature is not compatible with Solaris Zones partitioning technology. If you create a Solaris Flash archive, the resulting archive is not installed properly when the archive is deployed under these conditions:

Upgrading When Non-Global Zones Are Installed

Starting with the Solaris 10 1/06 release, when you are upgrading the Solaris OS, you can upgrade a system that has non-global zones installed. The Solaris interactive installation program and custom JumpStart programs enable an upgrade.

Caution – Caution –

You cannot use Solaris Live Upgrade to upgrade a system when non-global zones are installed. You can create a boot environment with the lucreate command, but if you use the luupgrade command, the upgrade fails. An error message is displayed.
