Information 

Solaris Installation program text installer 

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 or more slices 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. 

  • The installation GUI is not available to install a ZFS root pool.

  • You cannot create a Solaris Flash archive from a ZFS root pool. Also, you cannot install a Solaris Flash archive on a ZFS root pool.

  • You cannot use the standard upgrade program to upgrade. You must use Solaris Live Upgrade to upgrade a ZFS root pool.

Solaris Live Upgrade 

You can use the Solaris Live Upgrade feature 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 the other Solaris Live Upgrade commands on the boot environment.

  • A storage pool must be created before you use the lucreate command.

  • You cannot create a Solaris Flash archive from a ZFS root pool. Also, you cannot install a Solaris Flash archive on a ZFS root pool.

JumpStart 

You can create a profile to create a ZFS storage pool and designate a bootable ZFS file system. New ZFS keywords provide an initial installation. 

  • You cannot use the install_type upgrade keyword to upgrade a ZFS root pool. Nor can you use the Solaris Flash keywords.

  • Some keywords that are allowed in a UFS specific profile are not allowed in a ZFS specific profile.
