ATM Subsystem Manager (ASM)
The SCF objects for the ATM subsystem consist of manager and monitor processes
and several other objects that correspond to components of the ATM adapters that
connect the ATM network to the server.
The process and monitor objects correspond to the processes that manage (ASM) and
monitor (AMPs) the ATM subsystem through SCF.
The SCF objects related to the ATM adapters are the PROCESS, ADAPTER, LINE,
ATMSAP, PVC and SVC objects. Figure 2-4 shows the relationship between the ATM
SCF objects as they correspond to a ServerNet adapter.
ATM Subsystem Manager (ASM)
The ATM subsystem processes manage and control the ATM subsystem. The
subsystem manager process is the ASM process. The SUBSYS object represents the
ASM.
The ASM process ($ZZATM) is the central point of management for all ATM
connections in an NonStop S-series server. The ASM process runs as a process pair
and can only run in processors 0 and 1 (the same processors as the system disk).
ASM performs the following tasks:
Note. Programmatic management of the ATM subsystem through the Subsystem
Programmatic Interface (SPI) is not supported
