Expand Management Programming Manual

SECTION 6
COMMON DEFINITIONS
The management-programming interfaces to the EXPAND subsystem
make use of definitions from four different sources: the SPI
standard definitions, the EMS standard definitions, the data-
communications standard definitions, and the EXPAND definitions.
This section discusses the definitions from these four sources
that can be used in a management application to communicate with
the EXPAND subsystem.
The information in this section is general information that
applies to all uses of the definitions in the interface to
the EXPAND subsystem. Information about a definition that
is specific to a particular command, response, event message,
or error list is given in the description for that command,
response, event message, or error list.
All definitions in this section are represented in DDL.
Structures, both fixed and extensible, are defined by using DDL
DEF statements. For a quick explanation of DDL as it applies
to SPI, refer to the appendix "Overview of DDL for SPI" in the
Distributed Systems Management (DSM) Programming Manual .
SPI STANDARD DEFINITIONS
Definitions whose names begin with ZSPI- are Subsystem
Programmatic Interface (SPI) standard definitions.
Table 6-1 lists SPI standard definitions that are used in
the management-programming interfaces to the EXPAND subsystem.
These definitions consist of simple tokens that are used in
EXPAND commands, responses, event messages, and error lists;
header tokens and other special tokens that are available to
