SNAX/HLS Management Programming Manual

6 Common Definitions

This section presents the definitions used in the SNAX/HLS management
programming interfaces and the methods for using the definitions.
The standard definitions for SPI (ZSPI), EMS (ZEMS), data communications (ZCOM),
and ZCMK follow. See the Communications Management Programming Manual for
detailed descriptions of the ZCMK tokens.
Standard Subsystem
Programmatic
Interface Definitions
Definitions whose names begin with ZSPI– are standard SPI. The standard SPI
definitions used in the management programming interfaces to SNAX/HLS consist of
simple tokens used in commands, responses, event messages, and error lists. It also
consists of header tokens and other special tokens that are available to all applications
using SPI as well as fixed structures and token types used in other definitions.
All standard SPI definitions are fully described in the Distributed Systems Management
(DSM) Programming Manual. Information about these definitions that is specific to
SNAX/HLS is given below.
ZSPI–SSN–ZHLS
is the subsystem number assigned to the SNAX/HLS subsystem.
ZSPI–TKN–ALLOW
provides support, as described in the Distributed Systems Management (DSM)
Programming Manual.
The token type is ZSPI–TYP–ENUM. The particular value of interest to
SNAX/HLS is ZSPI–VAL–ALLOW–SEGMENTS. If this token is passed with this
value in a command buffer, and the response is one on which SNAX/HLS
provides segmentation, then the response will be segmented as necessary.
Consult the Distributed Systems Management (DSM) Programming Manual for a full
description of Segmented Responses.
See Section 7, “Commands and Responses,” for more information on how and
when SNAX/HLS implements segmented responses.
ZSPI–TKN–ALLOW–TYPE
provides support, as described in Distributed Systems Management (DSM)
Programming Manual.
ZSPI–TKN–COMMAND
contains the command number of a SNAX/HLS command. Command numbers
and their associated text are described in Section 7, "Commands and Responses."
