The following commands create a ZFS root pool and a new boot environment from a UFS root (/) file system in the ZFS root pool. A ZFS root pool must exist before the lucreate operation and must be created with slices rather than whole disks to be upgradeable and bootable. The disk cannot have an EFI label, but must be an SMI label. For more limitations, see System Requirements and Limitations When Using Solaris Live Upgrade.
Figure 11–1 shows the zpool command that creates a root pool, rpool on a separate slice, c0t1d0s5. The disk slice c0t0d0s0 contains a UFS root (/) file system. In the lucreate command, the -c option names the currently running system, c0t0d0, that is a UFS root (/) file system. The -n option assigns the name to the boot environment to be created, new-zfsBE. The -p option specifies where to place the new boot environment, rpool. The UFS /export file system and the /swap volume are not copied to the new boot environment.
This example shows the same commands as in Figure 11–1. The commands create a new root pool, rpool, and create a new boot environment in the pool from a UFS root (/) file system. In this example, the zfs list command shows the ZFS root pool created by the zpool command. The next zfs list command shows the datasets created by the lucreate command.

The new boot environment is rpool/ROOT/new-zfsBE. The boot environment, new-zfsBE, is ready to be upgraded and activated.
