tape load
and unloading them from the drives, and a means for an operator to load cartridges
into or remove cartridges from the tape library.
tape load. A system load. A tape load is the process of reading a system image tape (SIT)
and writing it to the system disk. Performing a tape load from a SIT to restore the
system image files to the $SYSTEM disk is generally not recommended. Perform a
tape load only with the advice of the Global Customer Support Center (GCSC) or your
service provider. Loading from a tape reinitializes the disk directory.
TAPE object type. The Subsystem Control Facility (SCF) object type for all tape drives
attached to your system.
target system. The computer system you make larger by adding enclosures, using a
process known as system expansion. See also donor system.
TB. See terabyte (TB).
TCP. See Transmission Control Protocol (TCP).
TCP/IP. See Transmission Control Protocol/Internet Protocol (TCP/IP).
TEMPLI. The Event Management Service (EMS) template installation program that merges
template object files from specified subsystems and produces resident and nonresident
template files.
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).
terminal. A type of Open System Services (OSS) character special file that conforms to the
interface description in Clause 7 of ISO/IEC IS 9945-1:1990.
terminator. A resistor connected to a signal wire in a bus or network for the purpose of
impedance matching to prevent reflections. SCSI chains, Ethernet cables, and some
LocalTalk wiring configurations require terminators.
Tetra 8 topology. A tetrahedral topology of HP NonStop™ S-series servers that allows a
maximum of four processor enclosures (eight processors) and eight I/O enclosures.
Contrast with Tetra 16 topology.
Tetra 16 topology. A tetrahedral topology of HP NonStop™ S-series servers that allows a
maximum of eight processor enclosures (16 processors). The maximum number of I/O
enclosures allowed by the Tetra 16 topology varies depending on the release version
update (RVU) and the server model. Contrast with Tetra 8 topology.
tetrahedral topology. A topology of HP NonStop™ S-series servers in which the ServerNet
connections between the processor enclosures form a tetrahedron. See also
tetrahedron and topology.
