IBM System Storage SAN Volume Controller: Hardware Installation Guide
In Metro or Global Mirror, the status condition that exists when both
virtual disks (VDisks) of a pair that has a copy relationship contain the
same data.
A functional unit, consisting of one or more computers and associated
software, that uses common storage for all or part of a program and also
for all or part of the data necessary for the execution of the program. A
computer system can be a stand-alone unit, or it can consist of multiple
connected units.
In decimal notation, 1 099 511 628 000 bytes.
The logical layout of the components of a computer system or network and
their interconnections. Topology deals with questions of what components
are directly connected to other components from the standpoint of being
able to communicate. It does not deal with questions of physical location
of components or interconnecting cables. (S)
An IBM product that provides an intelligent disk-storage subsystem across
an enterprise.
To initiate or reinitiate copying between a pair of virtual disks (VDisks)
that have a copy relationship.
See unique identifier.
A mode in which I/O operations cannot be performed. See also image mode
and managed space mode.
A device that is connected between a computer and its power source that
protects the computer against blackouts, brownouts, and power surges.
The uninterruptible power supply contains a power sensor to monitor the
supply and a battery to provide power until an orderly shutdown of the
system can be performed.
An identifier that is assigned to storage system logical units when they are
created. It is used to identify the logical unit regardless of the logical unit
number (LUN), status of the logical unit, or whether alternate paths exist
to the same device. Typically, a UID is only used once.
An access mode that pertains to a managed disk (MDisk) that is not used
by the cluster.
See uninterruptible power supply.
