Creating a Mirror in the md.tab File

This example shows a one-way mirror, /dev/md/dsk/d50, and two other concatenations that would be attached later to create a three-way mirror. The mirror does not contain any data.

#
#
# (mirror)
#
d50 -m d51
d51 1 1 c0t1d0s2
d52 1 1 c0t2d0s2
d53 1 1 c0t3d0s2

The -m creates a one-way mirror consisting of submirror d51. The other two submirrors, d52 and d53, must be attached later with the metattach(1M) command. The default read and write options in this example are a round-robin read policy and parallel write policy.
