To support booting from an Oracle Solaris ZFS on the SPARC platform, two new boot options have been added:
Displays a list of available bootable datasets within a ZFS pool.
Note - The boot -L command is executed from the OBP, not from the command line.
Boots the root file system for the specified ZFS bootable dataset.
If you are booting a system from a ZFS root file system, first use the boot command with the -L option from the OBP to print a list of the available BEs on the system. Then, use the -Z option to boot the specified BE.
For more information, see the boot(1M) man page.
On SPARC based systems, the menu.lst file contains the following two GRUB commands:
title – Provides a title for a boot environment (BE)
bootfs – Specifies the full name of the bootable dataset
To display a list of the bootable datasets within a ZFS pool, choose from the following methods:
Use the lustatus command. This command lists all of the BEs in a given ZFS pool.
Note that the lustatus command can also be used on x86 based systems.
Use the boot -L command. This command displays a list of the available BEs in a given ZFS pool and provides instructions for booting the system.
The following procedure describes how to use the boot -L command to list available BEs on a system. To boot a specified BE after running this command, follow the instructions that are printed on the screen.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
# init 0
ok boot device-specifier -L
For instructions, see SPARC: How to Boot From a Specified ZFS Root File System.

For more information, see Chapter 5, Installing and Booting an Oracle Solaris ZFS Root File System, in Oracle Solaris ZFS Administration Guide.
Booting from Oracle Solaris ZFS differs from booting from UFS. When booting from ZFS, a device specifier identifies a storage pool, not a single root file system. A storage pool can contain multiple bootable datasets, or root file systems. Therefore, when booting from ZFS, you must also identify a root file system within the pool that is identified by the boot device as the default. By default, the default boot device is identified by the pool's bootfs property. This procedure shows how to boot the system by specifying a ZFS bootable dataset. See the boot(1M) man page for a complete description of all the boot options that are available.
Note - If the bootfs property was previously set up correctly, for example, if you used the luactivate command to activate a BE, the system boots a ZFS root automatically.
For more information, see zpool(1M) man page.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
# init 0
For instructions, see SPARC: How to List Available Bootable Datasets Within a ZFS Root Pool.
Select environment to boot: [1 - 2]:
To boot the selected entry, invoke: boot [<root-device>] -Z rpool/ROOT/dataset
ok boot -Z rpool/ROOT/dataset
For example:
# boot -Z rpool/ROOT/zfs2BE
# prtconf -vp | grep whoami
# prtconf -vp | grep bootpath
Example 12-6 SPARC: Booting From a Specified ZFS Root File System
This example shows how to use the boot -Z command to boot a ZFS dataset on a SPARC based system.
