Glossary
AIX coexistence label
Data on disk which identifies the disk to the AIX volume manager (LVM) as being controlled by
VxVM. The contents has no relation to VxVM ID Blocks.
back-rev disk group
A disk group created using a version of VxVM released prior to the release of CDS. Adding CDS
functionality rolls over to the latest disk group version number; see also current-rev disk group.
CDS (Cross-platform Data Sharing)
Sharing data between heterogeneous systems (such as Solaris and HP-UX operating systems),
where each system has direct access to the physical devices used to hold the data, and understands
the data on the physical device. Sharing in this sense should not be confused with the sharing
provided with CVM by means of a shared disk group.
CDS disk
A disk whose contents and attributes are such that the disk can be used for CDS as part of a CDS
disk group. In contrast, a non-CDS disk cannot be used for CDS, nor can it be part of a CDS disk
group. CDS disk also contains a set of AIX Coexistence Labels, HP-UX Coexistence
Labels/VxVM ID Blocks, and Platform Blocks.
CDS disk group
A VxVM disk group whose contents and attributes are such that the disk group can be used to
provide CDS. In contrast, a non-CDS disk group (that is, a back-rev disk group or a current-rev
disk group) cannot be used for CDS. A CDS disk group is a current-rev disk group with the CDS
attribute set for the disk group. A CDS disk group can only contain CDS disks.
CFS
Cluster file system. A VxFS file system mounted on a selected volume in cluster (shared) mode.
children
Objects that belong to an object group.
