Symantec Product
Authentication Service
A component of Veritas Security Services (VxSS) that is used by CommandCentral
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
Authorization Service
A common component, also known as VRTSaz, that provides a centralized access
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
