SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

system
configuration
database
The database file on the $SYSTEM.ZSYSCONF subvolume that contains configuration information
for all system objects that can be configured by the Subsystem Control Facility (SCF). Configuration
information for all system objects that can be configured by SYSGENR is contained on the
$SYSTEM.SYSnn subvolume. See also configuration file and SYSnn subvolume.
system enclosure An enclosure for NonStop S-series system components. Processor enclosures and I/O enclosures
are both system enclosures. Contrast with peripheral enclosure.
system engineer
(SE)
See service provider.
system load 1. To start the system; to load the HP NonStop operating system image into the memory of a
processor.
2. The process of loading the operating system. A system load changes a system from an inactive
to an active (or operational) state by loading software that establishes communication between
the operating system and configured system peripherals.
system-managed
process
Another name for a generic process. See generic process.
TACL See HP Tandem Advanced Command Language (TACL).
tape drive A device that moves magnetic tape past magnetic read/write heads, which read data from or
write data to the tape.
TAPE object type The Subsystem Control Facility (SCF) object type for all tape drives attached to your system.
TB See terabyte (TB).
terabyte (TB) A unit of measurement equal to 1,099,511,627,776 bytes (1024 gigabytes). See also gigabyte
(GB), kilobyte (KB), and megabyte (MB).
TMF See HP NonStop™ Transaction Management Facility (TMF).
topology The physical layout of components that define a local area network (LAN), wide area network
(WAN), or ServerNet fabric.
topology branch A NonStop S-series processor enclosure and the I/O enclosures attached to it.
TSM See Compaq TSM.
TSM package See Compaq TSM package.
uninterruptable
power source
(UPS)
The equipment used to provide an uninterruptable source of power to connected equipment if a
main power outage occurs. The basic components of any UPS system are a rectifier/charger that
converts alternating-current (ac) power to direct-current (dc) power, batteries that store the dc
power, and an inverter that converts the dc power back into ac power for distribution to the load.
UPS See uninterruptable power source (UPS).
volume A logical disk drive, which can be one or two disk drives. In HP NonStop S-series systems, volumes
have names that begin with a dollar sign ($), such as $DATA. See also mirrored volume.
wild-card
character
A character that stands for any possible character or characters in a search string or in a name
applying to multiple objects. In Subsystem Control Facility (SCF) object-name templates, two
wild-card characters can appear:? (question mark) for a single character and * (asterisk) for zero
or more consecutive characters. See also object-name template.
world-wide name
(WWN)
A unique, 64-bit number assigned to hardware ports.
WORM Write-Once Read-Many times. A media storage class in which data, once written, cannot be
erased or overwritten.
WWN See world-wide name (WWN).
WWN zone Similar to Ethernet virtual LANs (VLANs), WWN zones organize the cabling and interactions
between components in a storage and server system.
X fabric The X side of the internal or external ServerNet fabrics. See also fabric.
Y fabric The Y side of the internal or external ServerNet fabrics. See also fabric.
