Lucent Technologies 585-210-940 manual d x y 1 device, Installing Mirrored Systems

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 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 --------------
