Figure 6–6 shows a new boot environment that contains a RAID-1 volume (mirror). The following command created the new boot environment and the mirror.
# lucreate -n second_disk -m /:/dev/md/dsk/d20:ufs,mirror \ -m /:/dev/dsk/c0t1d0s0:detach,attach,preserve
This command performs the following tasks:
Creates a new boot environment, second_disk.
Breaks mirror d10 and detaches concatenation d12.
Preserves the contents of concatenation d12. File systems are not copied.
Creates a new mirror d20. You now have two one-way mirrors d10 and d20.
Attaches concatenation d12 to mirror d20.
