Symantec Product

A component of Veritas Security Services (VxSS) that is used by CommandCentral

Authentication Service

Storage to provide user authentication. Authentication Service is a set of processes

 

and runtime libraries that enables users to log on to multiple Veritas products

 

with one login. See also Symantec Product Authorization Service.

Symantec Product

A common component, also known as VRTSaz, that provides a centralized access

Authorization Service

control decision-making service. After the Authentication Service has validated

 

user identities, the Authorization Service makes access control decisions,

 

determining whether specific users have the authority to perform specific tasks

 

on specific resources being protected by authorization. The Hardware Abstraction

 

Layer (HAL) is the only part of CommandCentral Storage to use the Authorization

 

Service, using it to control access for inter-process communication. See also

 

Symantec Product Authentication Service.

system

The physical hardware on which data and applications reside, and the connections

 

between them.

tape device

A storage device that writes data to tape. CommandCentral Storage identifies a

 

tape drive, tape transport, and tape arrays as a tape device.

tape mark

A mark that is recorded between backup images on a tape.

Task Manager

A CommandCentral Storage Management Server component that manages

 

user-initiated requests to requests to change the status or configuration of objects

 

in the network and to add, edit, and delete users. The Task Manager maintains a

 

list of completed, pending, and active tasks. The list can be viewed using the

 

Console Task Status tab.

topology

The physical or logical arrangement of resources on the storage network and the

 

connections between them.

Topology Map

A graphical representation of the physical or logical arrangement of storage

 

resources in the network. The Topology Map depicts both the objects on the

 

network and the connections between them. In CommandCentral Storage, the

 

Topology Map displays on the Console's Topology tab.

unallocated storage

LUNs that have not yet been allocated. A LUN is considered allocated when a host

 

operating system has written a device handle for the LUN (in other words, claimed

 

the LUN) or when the array has masked the LUN to a specific target. Contrast

 

with allocated storage

unclaimed storage

Storage that has been allocated to hosts whose operating systems have not yet

 

written device handles. This is usually wasted storage. Contrast with claimed

 

storage

unconfigured storage

Physical storage that has yet to be formatted. Contrast with configured storage

unidentified adapter

An HBA or storage device that has logged into a Fibre Channel switch and about

 

which CommandCentral Storage has no information. For HBAs, this can occur
