sensitive command
sensitive command. A Subsystem Control Facility (SCF) command that can be issued only
by a user with super-group access, by the owner of the subsystem, or by a member of
the group of the owner of the subsystem. The owner of a subsystem is the user who
started that subsystem (or any user whose application ID is the same as the server
ID—the result of a PROGID option that requires super-group access). Contrast with
nonsensitive command.
ServerNet adapter. A component that connects peripheral devices to the rest of the system
through a ServerNet bus interface (SBI). A ServerNet adapter is similar in function to
an I/O controller logic board (LB) and backplane interconnect card (BIC) in HP
NonStop K-series servers.
ServerNet addressable controller (SAC). An I/O controller that is uniquely addressable by
a ServerNet ID in the ServerNet fabrics. 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 45xx disk or
tape drives installed in a modular storage subsystem. The 6760 ServerNet/DA contains
up to four ServerNet addressable controllers (SACs), each of which can control either
disk drives or tape drives.
ServerNet expansion board (SEB). (1) A connector board that plugs in to the backplane to
allow one or more ServerNet cables to exit the rear of the enclosure. The SEBs and
ServerNet cables allow processors in one group to communicate with processors in
another group. Each SEB provides either the ServerNet X fabric or the ServerNet Y
fabric for a group. (2) A collective term for both SEBs and modular SEBs (MSEBs)
when a distinction between the two types of SEBs is not required.
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 HP NonStop S-series server. The HP TSM
package allows you to use the help of a service provider by configuring TSM to support
remote notification and remote access.
slot. A physical, labeled space for a customer-replaceable unit (CRU) or field-replaceable
unit (FRU) that is part of a module. A module contains one or more slots.
slot location. A three-number identifier for a particular slot on a system that consists of the
group number, module number, and slot number; for example, 02,01,08 (group 02,
module 01, slot 08).
small computer system interface (SCSI). An ANSI-standard protocol used by a controller
to access a device.
SMF. See Storage Management Foundation (SMF).
