How CMS implements disk mirroring
CentreVu CMS Release 3 Version 8 Disk-Mirrored Systems
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
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
d21
d20
