Overview of SLSA
Table 2-1. SLSA Software Components
SLSA Software Component Description
LAN manager (LANMAN)
process

Manages all SLSA objects in the system

Receives management commands from the user
through SCF and communicates the commands to a
LANMON process

Starts and stops the LANMON processes in each
processor

Manages the assignment of adapters to specific
LANMON processes
For more information about LAN manager, see Processes
on page 2-11.
LAN monitor (LANMON)
process

Provides trace facilities for all LAN access through a
specific processor

Handles events for itself, the driver interrupt handler
(DIH), and the adapter

Controls adapters communicating with LANMON by
means of DIH

Manages error recovery of adapters, SACs, and PIFs.
For more information about LAN monitor, see Monitors
on
page 2-12.
driver interrupt handler (DIH) DIH is a component of the SLSA subsystem that is
responsible for the transfer of data and management
information and error handling. It is the interface between
the rest of the SLSA subsystem and the communications
adapter hardware.
For more information about DIH, see System-Level
Processes and Libraries on page 2-8.
LAN manager library (LMLIB) LMLIB is a shared library of function calls used for internal
purposes only. These calls provide an interface for the
SLSA objects. LMLIB is used by the LANMAN and
LANMON processes to:

Add or delete an object

Retrieve the current state information about an object

Modify the state of an object

Retrieve or modify the attributes of an object
