Create a Boot Environment and Use the Existing Submirror

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.
