How CMS implements disk mirroring1
A nonmirrored, CMS system with Solstice DiskSuite uses it to create a 
single metadevice, named d19, containing all the disk partitions used to 
store CMS data. For example: 
To implement disk mirroring, a metadevice d20 is created as a duplicate 
of d19, and the two metadevices are configured as submirrors of d21, as 
shown in the following...

In a CMS computer system with 
/cms mirrored, root is also mirrored. The 
root mirror is d13; its submirrors are d11 and d12. For example:
If your computer system is running CMS r3v8, your swap partition is also 
mirrored. The swap mirror is d17; its submirrors are d15 and d16. For 
example:
d11

Mirror layouts1Mirror layouts on a factory-installed mirrored system differ depending 
upon the platform. When a system is upgraded to mirroring in the field, 
mirror layouts are essentially unpredictable, and depend on how many 
disk drives are already installed, and what their target numbers are.

On a Sun Enterprise 3500 platform, the mirror layout must always be 
based upon the bays in which the disks are installed. Submirrors 11, 15, 
and 19 are the disks in the lower bay (targets 0 through 3 on controller 0); 
submirrors 12,16, and 20 are the disks in the upper bay (targets 4 
through 7 on controller 1). The table below...

If you intend to increase your system capacity as well as mirror your 
system, first install the new disks needed to increase capacity. For 
instructions, see the documentation that came with the new drives or the 
appropriate Lucent Technologies installation documents. After the system 
capacity has been increased, and it has been...

b. Record existing nonboot disks under submirror 19, and empty 
slots for new nonboot disks under submirror 20.
Example: Imagine a system that already has two disk drives in 
slots 0 and 1. In the previous step, you would have reserved 
slot 2 for the second boot disk. The remaining new disk is a 
nonboot disk and will be installed in slot 3. So you would record...

Do this step only if you have an Enterprise 3500 system.
It is likely that your 
Enterprise 3500 system is currently using controller 1 
(c1) for the internal CD-ROM drive. This step associates the CD-ROM 
drive with controller 2 (c 2) so controller 1 will be free for the new disk 
drives. In this...
