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.
Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Create the boot environment.
# lucreate [-A 'BE_description'] -s source_BE_name -m mountpoint:device[,metadevice]:fs_options -n BE_name
(Optional) Enables the creation of a boot environment description that is associated with the boot environment name (BE_name). The description can be any length and can contain any characters.
Specifies the source boot environment for the new boot environment. The source would not be the active boot environment.
Specifies the file systems' configuration of the new boot environment. The file systems that are specified as arguments to -m can be on the same disk or they can be spread across multiple disks. Use this option as many times as needed to create the number of file systems that are needed.
mountpoint can be any valid mount point or – (hyphen), indicating a swap partition.
device field can be one of the following:
The name of a disk device, of the form /dev/dsk/cwtxdysz
The name of a Solaris Volume Manager metadevice, of the form /dev/md/dsk/dnum
The name of a Veritas Volume Manager volume, of the form /dev/vx/dsk/volume_name
The keyword merged, indicating that the file system at the specified mount point is to be merged with its parent
fs_options field can be one of the following:
ufs, which indicates a UFS file system.
vxfs, which indicates a Veritas file system.
swap, which indicates a swap file system. The swap mount point must be a – (hyphen).
For file systems that are logical devices (mirrors), several keywords specify actions to be applied to the file systems. These keywords can create a logical device, change the configuration of a logical device, or delete a logical device. For a description of these keywords, see To Create a Boot Environment With RAID-1 Volumes (Mirrors) (Command-Line Interface).
The name of the boot environment to be created. BE_name must be unique on the system.
When creation of the new boot environment is complete, it can be upgraded and activated (made bootable). See Chapter 9, Upgrading With Solaris Live Upgrade (Tasks).
In this example, a boot environment is created that is based on the root (/) file system in the source boot environment named third_disk. Third_disk is not the active boot environment. A description, mydescription, is associated with the new boot environment named second_disk.
# lucreate -A 'mydescription' -s third_disk \ -m /:/dev/dsk/c0t4d0s0:ufs -n second_disk
