How CMS implements disk mirroring 1
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 example:
d19
/cms

c0t0d0s3
c0t1d0s1
(disk n)
d19
/cms
