SCSI plug-in card (S-PIC)
SCSI plug-in card (S-PIC). A plug-in card (PIC) for the 6760 ServerNet device adapter
(ServerNet D/A) that uses a small computer system interface (SCSI) interface to
connect 9490, 5150, and 519x tape drives to a Compaq NonStop Himalaya S-series
system. See also plug-in card (PIC)
and fiber-optic plug-in card (F-PIC).
ServerNet addressable controller (SAC). On Compaq NonStop Himalaya S-series
servers, an I/O controller that is uniquely addressable by a ServerNet ID in the
ServerNet fabric. A SAC is typically implemented on some portion of a processor
multifunction (PMF) customer-replaceable unit (CRU), an I/O multifunction (IOMF)
CRU, or a ServerNet adapter.
ServerNet/DA. See ServerNet device adapter (ServerNet/DA).
ServerNet device adapter (ServerNet/DA). A ServerNet adapter that controls external
devices. The 6760 ServerNet/DA contains up to four ServerNet addressable
controllers (SACs), each of which can control either disk drives or tape drives.
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your Compaq NonStop Himalaya server.
SETMODE procedure call. A Guardian procedure call that requests system services to
set device-dependent characteristics.
small computer system interface (SCSI). An ANSI-standard protocol used by a
controller to access a device.
S-PIC. See SCSI plug-in card (S-PIC).
streaming tape operation. Continuous tape motion by a tape drive, as opposed to
start/stop tape operation.
Subsystem Control Facility (SCF). An interactive interface for configuring, controlling, and
collecting information from subsystems and objects. On G-series releases, SCF
enables you to configure and reconfigure devices, processes, and some system
variables while your Compaq NonStop Himalaya S-series server is online.
SYSGENR. The system generation program that generates a customized version of the
Compaq NonStop Kernel operating system.
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 DEFINE. A named set of attributes and values that specifies information about a tape
file. There are two types of tape DEFINEs: CLASS TAPE DEFINEs and CLASS
TAPECATALOG DEFINEs.
tape drive. A device that moves magnetic tape past magnetic read/write heads, which read
data from or write data to the tape.
