Starting with the Solaris 10 10/08 release, you can install and boot a ZFS root file system.
The Solaris text installer performs an initial installation for a ZFS root pool. During the installation, you can choose to install either a UFS file system or a ZFS root pool. You can set up a mirrored ZFS root pool by selecting two disks during the installation. Or, you can attach or add additional disks after the installation to create a mirrored ZFS root pool. Swap and dump devices on ZFS volumes are automatically created in the ZFS root pool.
For step-by-step instructions, see Chapter 3, Installing With the Solaris Interactive Text Installer for ZFS Root Pools (Planning and Tasks), in Solaris 10 10/09 Installation Guide: Basic Installations.
With custom JumpStart, you can create a profile to create a ZFS storage pool and designate a bootable ZFS file system. New ZFS profile keywords install a ZFS root pool for an initial installation. A ZFS profile contains a limited set of keywords.
For more information about JumpStart and ZFS, see Chapter 9, Installing a ZFS Root Pool With JumpStart, in Solaris 10 10/09 Installation Guide: Custom JumpStart and Advanced Installations
You can use Solaris Live Upgrade to perform the following tasks:
Migrate a UFS root (/) file system to a ZFS root pool
Create a new boot environment in the following ways:
Within an existing ZFS root pool
Within another ZFS root pool
From a source other than the currently running system
On a system with non-global zones installed
After you have used the lucreate command to create a ZFS boot environment, you can use other Solaris Live Upgrade commands on the boot environment, such as the luupgrade and luactivate commands. For more information on using Solaris Live Upgrade for ZFS, see Chapter 11, Solaris Live Upgrade and ZFS (Overview), in Solaris 10 10/09 Installation Guide: Solaris Live Upgrade and Upgrade Planning.
Starting with the Solaris 10 10/08 release, the structure of the Solaris Operating System DVD and Solaris Software - 1 CD have changed for the SPARC platform. Slice 0 is no longer at the top of the directory structure. Therefore, the structure of the x86 and SPARC DVD and Solaris Software - 1 CD are the same. This change in structure makes setting up an install server easier if you have a mix of platforms, such as a SPARC install server and x86 media. For procedures for setting up an install server, see the following:
