Installation manual

Hierarchical Storage Controller (HSC) device
A self-contained, intelligent, mass storage subsystem that lets computers in a
cluster environment share disks. Examples are the HSC50 and the HSC70.
HSC drive
Any disk or tape drive connected to an HSC device is called an HSC drive. A
system disk on an HSC drive can be shared by several computers in an OpenVMS
Cluster environment.
InfoServer
A general-purpose disk storage server that allows you to use the distribution
compact disc to install the operating system on remote client systems connected
to the same local area network (LAN).
local area OpenVMS Cluster system
A configuration consisting of one or more computers that act as a MOP server
and disk server, and a number of low-end computers that act as satellite nodes.
The local area network (LAN) connects all of the computers. These computers
share a single file system.
local drive
Any drive that is connected directly to a computer. If you have a standalone
computer, it is likely that all drives connected to the system are local drives.
media
Any packaging agent capable of storing computer software (For example, compact
discs, magnetic tapes, floppy disks, disk packs, and tape cartridges.)
MOP server
A computer system running DECnet software that downline loads OpenVMS
Cluster satellites using the DECnet maintenance operations protocol.
OpenVMS Cluster environment
A computer system consisting of two or more VAX or Alpha computers. There are
four types of OpenVMS Cluster environments: CI only, DSSI only, local area, and
mixed-interconnect.
satellite node
A computer that is part of a local area cluster. A satellite node is downline loaded
from a MOP server and then boots remotely from the system disk served by
a disk server in the local area cluster. See also boot server, disk server, MOP
server.
save set
The format in which the Backup utility stores files. The OpenVMS operating
system is shipped in this format.
scratch disk
A blank disk or a disk with files you no longer need.
source drive
The drive that holds the distribution kit during an upgrade or installation.
