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 page 13
.
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 --------------
