system resource model (SRM)
system resource model (SRM). A collection of C++ objects that model the diagnostic and
serviceability state behavior of the system resources discovered and managed by the
Compaq TSM package. The SRM has these attributes:
system serial number. A unique identifier, typically five or six alphanumeric characters,
assigned to an HP NonStop™ S-series server when it is built.
System Service Information (SSI) log. An Event Management Service (EMS) log that
includes information about customer-replaceable unit (CRU) removal, CRU insertion,
firmware loading, security authentication, incident report dial-out authorization, incident
report dial-out failure, and incident report confirmation. The SSI log can be viewed
using the OSM or TSM Event Viewer.
system terminal. See system console.
System V. A version of UNIX developed and marketed originally by AT&T.
TACL. See HP Tandem Advanced Command Language (TACL).
tape bootstrap. The program on a system image tape (SIT) that reads the rest of the SIT
during tape load and writes it to the system disk.
tape drive. A device that moves magnetic tape past magnetic read/write heads, which read
data from or write data to the tape.
tape dump. To copy the memory of a processor to tape.
tape library. A storage device consisting of magnetic tape drives, multiple storage locations
for magnetic tape cartridges, an automatic mechanism for loading the cartridges into
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).
