Installing Mirrored Systems 
CentreVu CMS Release 3 Version 8 Disk-Mirrored Systems
How to upgrade an Enterprise platform to disk mirroring
19
The root metadevice definitions go into the #metaroot section, 
which you must create for the occasion; d20 goes into the #/cms 
section, which already exists in the file. The swap metadevice 
definitions go into the #swap section which, like #metaroot, must 
be created for the occasion.
The lines you add must be in the following general format:
d<
x>
<y>
1
<device>
d
<x> is the metadevice name. 
<y> denotes the total number of disks named in the line.
1 
<device> indicates one disk with the device name <device>. You 
should have recorded the device names on 
The pattern 1 (space) 
<device> repeats until all disks in the 
metadevice have been named. The d12 entry must specify one disk; 
the d20 entry must specify the same number of disks as the existing 
d19 entry. If your system has two disks in slots 0 and 1 and you are 
adding a two-disk mirror in slots 2 and 3, for example, you would 
add the 
md.tab lines shown in boldface in the following sample: 
-------- /etc/opt/SUNWmd/md.tab - EXAMPLE ONLY --------------
