This example shows the attaching of a submirror, d70, to a one-way mirror, d30, creating a two-way mirror. The mirror d30 initially consists of submirror d60. The submirror d70 is a RAID 0 volume. You verify that the status of the mirror is “Okay” with the metastat command, then attach the submirror. When the metattach command is run, the new submirror is resynchronized with the existing mirror. When you attach an additional submirror to the mirror, the system displays a message. To verify that the mirror is resynchronizing, use the metastat command.
