Active/Active disk arrays
This type of multipathed disk array allows you to access a disk in the disk array through all
the paths to the disk simultaneously, without any performance degradation.
Active/Passive disk arrays
This type of multipathed disk array allows one path to a disk to be designated as primary
and used to access the disk at any time. Using a path other than the designated active path
results in severe performance degradation in some disk arrays. Also see path, primary
path, and secondary path.
associate
The process of establishing a relationship between VxVM objects; for example, a subdisk
that has been created and defined as having a starting point within a plex is referred to as
being associated with that plex.
associated plex
A plex associated with a volume.
associated subdisk
A subdisk associated with a plex.
atomic operation
An operation that either succeeds completely or fails and leaves everything as it was before
the operation was started. If the operation succeeds, all aspects of the operation take effect
at once and the intermediate states of change are invisible. If any aspect of the operation
fails, then the operation aborts without leaving partial changes.
In a cluster, an atomic operation takes place either on all nodes or not at all.
attached
A state in which a VxVM object is both associated with another object and enabled for use.
block
The minimum unit of data transfer to or from a disk or array.
boot disk
A disk that is used for the purpose of booting a system.
boot disk group
A private disk group that contains the disks from which the system may be booted.
bootdg
A reserved disk group name that is an alias for the name of the boot disk group.
clean node shutdown
The ability of a node to leave a cluster gracefully when all access to shared volumes has
ceased.
