The lucreate command creates a boot environment that is based on the file systems in the active boot environment. If you want to create a boot environment based on a boot environment other than the active boot environment, use lucreate with the -s option.
If you activate the new boot environment and need to fall back, you boot back to the boot environment that was last active, not the source boot environment.
Log in as superuser.
Create the boot environment.
# lucreate [-A 'BE_description'] -s source_BE_name -m mountpoint:device:fs_type -n BE_name |
In this example, a boot environment is created based on the root (/) file system in the source boot environment named third_disk. Third_disk is not the active boot environment. A description, Solaris 9 test Jan. 2001, is associated with the new boot environment named second_disk.
# lucreate -A 'Solaris 9 test Jan 2001' -s third_disk \ -m /:/dev/dsk/c0t4d0s0:ufs -n second_disk |
When creation of the new boot environment is complete, it can be upgraded and activated (made bootable). See Chapter 33, Upgrading With Solaris Live Upgrade (Tasks).
