response
response. In DSM use, the information or confirmation supplied (as part of a response
message) to an application by a subsystem in response to a DSM command.
response message. An SPI message sent from a subsystem to an application program in
reaction to a command message. Compare command message or event message.
response record. In DSM programmatic interfaces, a set of response tokens usually
describing the result when a command is performed on one object. Every response
record in a response from an HP subsystem contains a return token; a response
record can also contain error lists that include error tokens. A response can consist of
multiple response records, spread across one or more response messages. A
response record cannot be split between two response messages. If multiple response
records are in a response message, each response record is enclosed in a data list.
See also data list. Each response record is required to contain a return token. See also
return token.
return token. In DSM programmatic interfaces, the token that indicates whether a
command was successful and, if not, why it failed. The token code for the return token
is ZSPI-TKN-RETCODE. Its value consists of a single integer field. Compare error
token.
RFC (Request for Comments). See Request for Comments.
router. A node that forwards IP packets not explicitly addressed to itself.
SAC. See ServerNet addressable controller (SAC).
SCF. See Subsystem Control Facility (SCF).
SCP. See Subsystem Control Point (SCP).
secondary route. For multiple routes to the same destination, all the routes in addition to
the primary route (the route visible to Radix Routing topology) are called
shadow/secondary routes. Also called shadow route
on page -18.
sensitive command. In DSM, a command that can be issued only by a restricted set of
Guardian users, such as the owner of a subsystem process. For HP data
communications subsystems, the sensitive commands are those that can change the
state or configuration of objects, start or stop tracing, or change the values of statistics
counters. Compare nonsensitive command.
ServerNet adapter. A customer-replaceable unit (CRU) 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 NonStop K-series servers.
ServerNet addressable controller (SAC). A controller that is uniquely addressable within
one or more ServerNet address domains (SADs) through the node ID and address
fields in a request packet. A SAC typically is implemented on some portion of a
