The ZFS storage pool must be created with slices rather than with whole disks to be upgradeable and bootable.
Before you create the new pool, ensure that the disks to be used in the pool have an SMI (VTOC) label instead of an EFI label.
For example, a system with 12 GB of disk space might be too small for a bootable ZFS environment because 2 GB of disk space is required for each swap and dump device and approximately 6 GB of disk space is required for the ZFS BE that is migrated from the UFS BE.
In this Solaris release, you can perform an initial installation by using the Solaris interactive text installer to create a ZFS storage pool that contains a bootable ZFS root file system.
You can use the flash archive installation method as follows: Full Flash Checking integrity... Consider the following issues before starting a Jump Start installation of a bootable ZFS root file system: For information about ZFS and Oracle Solaris Live Upgrade requirements, see Oracle Solaris Installation and Oracle Solaris Live Upgrade Requirements for ZFS Support.
Review the following issues before you use Oracle Solaris Live Upgrade to migrate your UFS root file system to a ZFS root file system: operation.
However, they can only be upgraded using the Live Upgrade tools. If you will be configuring zones after the Jump Start installation of a ZFS root file system and you plan on patching or upgrading the system, see Using Oracle Solaris Live Upgrade to Migrate or Upgrade a System With Zones (Solaris 10 10/08) or Using Oracle Solaris Live Upgrade to Migrate or Upgrade a System With Zones (at Least Solaris 10 5/09).
The following screens will only allow you to install a ZFS root system, not upgrade one. The following keywords are permitted in a ZFS specific profile: Automatically specifies the size of the slices for the pool, swap volume, or dump volume.
There are existing ZFS pools available on this system.If you select a ZFS root file system, you are prompted to create a ZFS storage pool. For example, if you specify value means that the installation software selects a suitable device.The steps for installing a ZFS root file system follow: If you did not create a mirrored ZFS root pool during installation, you can easily create one after the installation. You can mirror as many disks as you like, but the size of the pool that is created is determined by the smallest of the specified disks.When a system is installed or upgraded with a ZFS root file system, the size of the swap area and the dump device are dependent upon the amount of physical memory.
The minimum amount of available pool space for a bootable ZFS root file system depends upon the amount of physical memory, the disk space available, and the number of boot environments (BEs) to be created.
For information about replacing a disk in root pool, see How to Replace a Disk in the ZFS Root Pool. For more information about creating mirrored storage pools, see Mirrored Storage Pool Configuration. This pool is created with a 2-GB swap volume and a 2-GB dump volume, in a mirrored configuration of any two available devices that are large enough to create an 80-GB pool.
