HP P6000 Replication Solutions Manager CLI Reference (T3680-96071, June 2012)

mirrorclone is said to be synchronized. In a synchronized state, the mirrorclone is automatically
updated whenever the source virtual disk is updated. When local replication between a
synchronized mirrorclone and the source is stopped by an action or command, the mirrorclone
is said to be fractured. In a fractured state, the mirrorclone is not updated when the source virtual
disk is updated. At the instant replication is stopped, the mirrorclone is a point-in-time copy of its
source.
mirrored caching A process in which half of each controller’s write cache mirrors the companion controller’s write
cache. The total memory available for cached write data is reduced by half, but the level of
protection is greater.
mount point A host's file system path or directory name where a host volume (device) is accessed.
N
normalization The background process of copying the contents of a source virtual disk to a snapclone. The
snapclone is dependent on the source until normalization is complete. Also called unsharing.
P
present The array controller's act of making a virtual disk accessible to a host computer.
R
remote client Component software that allows you to use the CLUI on the replication manager's enabled hosts.
remote copy A copy of a virtual disk on the destination array.
resource An object in the Replication Solutions Manager navigation pane; namely, DR groups, enabled
hosts, host volumes, managed sets, storage systems, and virtual disks. Replication is performed
using these resources.
RSM Replication Solutions Manager.
S
SAN Storage area network. A network of storage devices and the initiators that store and retrieve
information on those devices, including the communication infrastructure.
snapclone A copy that begins as a fully allocated snapshot and becomes an independent virtual disk. Applies
only to the HP EVA.
snapshot A nearly instantaneous copy of the contents of a virtual disk created without interruption of
operations on the source virtual disk. Snapshots are typically used for short-term tasks such as
backups.
storage array See array.
V
Vdisk See virtual disk.
virtual disk Variable disk capacity that is defined and managed by the array controller and presented to
hosts as a disk. May be called Vdisk in the user interface.
VM Virtual machine, guest operating system installed on VMware ESX server.
Vraid The level to which user data is protected. Redundancy is directly proportional to cost in terms of
storage usage; the greater the level of data protection, the more storage space is required.
