Virtual disks are the entities that are replicated using the HP
StorageWorks Enterprise Virtual Array snapshot functionality.
See also source volume and target volume.
virtual server A virtual machine in a cluster environment defined in a domain
by a network IP name and address. Its address is cached by
the cluster software and mapped to the cluster node that is
currently running the virtual server resources. This way all
requests for a particular virtual server are cached by a specific
cluster node.
volume group A unit of data storage in an LVM system. A volume group can
consist of one or more physical volumes. There can be more
than one volume group on the system.
volume mount
point
(Windows specific term) An empty directory on a volume that
can be used to mount another volume. The volume mount point
acts as a gateway to the target volume. Provided that the volume
is mounted, users and applications can refer to the data on the
mounted volume by the full (merged) filesystem path as if both
volumes are one integral part.
Volume Shadow
Copy Service
See Microsoft Volume Shadow Copy Service.
VSS See Microsoft Volume Shadow Copy Service.
VSS compliant
mode
(HP StorageWorks Disk Array XP VSS provider specific term)
One of two XP VSS hardware provider operation modes. When
the XP provider is in the VSS compliant mode, the source volume
(P-VOL) and its replica (S-VOL) are in simplex, unpaired state
after a backup. Therefore the number of replicas (S-VOLs per a
P-VOL) rotated is not limited. Restore from a backup in such a
configuration is possible only by switching of the disks.
See also resync mode, source volume, primary volume (P-VOL),
replica, secondary volume (S-VOL), and replica set rotation.
Wake ONLAN Remote power-up support for systems running in power-save
mode from some other system on the same LAN.
wildcard character A keyboard character that can be used to represent one or many
characters. The asterisk (*), for example, typically represents
one or more characters, and the question mark (?) typically
represents a single character. Wildcard characters are often
