SPARC: How to Select the Boot Environment for Booting

  1. After a ZFS BE is activated, display a list of bootable file systems within a ZFS pool. 
    $ boot -L
  2. Select one of the bootable file systems in the list.

    Detailed instructions for booting that file system are displayed.

  3. Boot the selected file system by following the instructions.
  4. Use the boot -Z filesystem command to boot a specific ZFS file system.
  5. To make the selected BE persistent across reboots, activate the BE.

Example 6-12 Booting From a Specific ZFS Boot Environment

If you have multiple ZFS BEs in a ZFS storage pool on your system's boot device, use the beadm activate command to specify a default BE.

In this example, the beadm lists following available ZFS BEs: 

$ beadm list
BE        Active Mountpoint Space Policy Created
--        ------ ---------- ----- ------ -------
solaris   NR     /          3.80G static 2012-07-20 10:25
solaris-2 -      -          7.68M static 2012-07-19 13:44

To select a specific BE, you would use the boot -L command. For example: 

ok boot -L
Boot device: /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/disk@0,0:a  File and args: -L
1 release-version SPARC
2 solaris
Select environment to boot: [ 1 - 2 ]: 1

To boot the selected entry, invoke:
boot [<root-device>] -Z rpool/ROOT/solaris-2

Program terminated
ok boot -Z rpool/ROOT/solaris-2

To boot automatically from the selected BE, activate that BE.
