How CMS implements disk mirroring
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:
/cms
d19
c0t0d0s3 |
|
|
|
|
|
| . . . |

|
c0t1d0s1 |
|
|
|
|
| (disk n) | ||
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 example:
/cms
d19
c0t0d0s3 |
d21
d20
c0t1d0s3
| . . . |
c0t2d0s1 | (disk n) |
. . . |
c0t3d0s1 | (disk n) |
