TSM workstation
TSM workstation. A PC-compatible workstation on which the Compaq Tandem Service
Management (TSM) client software is running. The TSM workstations configured as the
primary and backup dial-out points are referred to as the primary and backup system
consoles.
unplanned outage. Time during which the system is not capable of doing useful work
because of an unplanned interruption. Unplanned interruptions can include failures
caused by faulty hardware, operator error, or disaster. Contrast with planned outage. See
unstructured file. An array of bytes of data; it often contains text or program code.
VID. See
ViewSys. An interactive utility that monitors system resources while the system is running.
volume. A physical disk pack mounted on a disk drive. A mirrored volume is a pair of
physically independent disk packs that are configured and accessed as a single volume.
One is the primary volume and the other is the mirror volume. All data written to one
disk is written to the other as well. As long as both devices are operable, all data read
from one disk could just as well be read from the other, because the content of both
disks is the same.
volume ID number (VID). A string of up to six alphanumeric characters; for example,
“AMBER1”, that is assigned to a tape during the MEDIACOM ADD TAPELABEL
operation. This ID exists only for standard labeled tapes, and it resides on the tape’s first
volume label and should also be on a hand-written label, which identifies the tape.
volume mode. The mode of operation in which Backup or Restore copies an entire disk
volume of files.
VPROC. A utility program that displays product version information for object (file code
100) files.
WAN. See
WAN concentrator. See
ServerNet Wide Area Network (SWAN) concentrator
.
wide-area network (WAN). A network that operates over a larger geographical area than a
LAN (typically, an area with a radius greater than one kilometer). The elements of a
WAN may be separated by distances great enough to require telephone communications.
Contrast with
$ZSVR. A labeled-tape server process. It is an optional product, without which you can
perform only unlabeled-tape operations. When an application tries to open a labeled
tape, it sends an open request to $ZSVR. $ZSVR checks to see whether the requested
tape is mounted, and if it is not, $ZSVR sends an operator message to alert operations
staff to mount that tape.
