You can use the lucreate command with the -m option to specify which file systems and the number of file systems to be created in the new boot environment. You must specify the exact number of file systems you want to create by repeating this option. For example, a single use of the -m option specifies where to put all the file systems. You merge all the file systems from the original boot environment into one file system. If you specify the -m option twice, you create two file systems.
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.
# lucreate -A 'BE_description' \ -m mountpoint:device[,metadevice]:fs_options \ -m [...] -m mountpoint:merged: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 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, the file systems on the current boot environment are root (/), /usr, and /opt. The /opt file system is combined with its parent file system /usr. The new boot environment is named second_disk. A description, mydescription, is associated with the name second_disk.
# lucreate -A 'mydescription' -c first_disk \ -m /:/dev/dsk/c0t4d0s0:ufs -m /usr:/dev/dsk/c0t4d0s1:ufs \ -m /usr/opt:merged:ufs -n second_disk
