Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

10 SCF Reference for CIP
This section provides information about:
• The Subsystem Control Facility (SCF)
• SCF commands available for CIP
• Trace commands available for CIP
SCF for Cluster I/O Protocols
SCF provides an operator interface to an intermediate process, the Subsystem Control Point (SCP),
which in turn provides the interface to the I/O processes of the various subsystems.
The CIP subsystem runs on the NonStop system and the CLuster I/O Module (CLIM). This chapter
explains the SCF commands that control the SCF objects that reside on the NonStop host system
and on the CLIM.
The CIP subsystem supports Ethernet connectivity.
SCF Commands for CIPMAN Compared to SCF Commands for CIPSAM
This section describes SCF command syntax for both the CIPMAN and the CIPSAM processes.
CIPSAM SCF syntax differs from CIPMAN syntax because CIPSAM provides backward compatibility
for applications. The CIPSAM and CIPMAN processes support different subordinate objects and
yield different command results for subordinate objects they share. For example, CIPMAN does
not have a SUBNET object. The SUBNET object is supported for the CIPSAM process to allow
applications to obtain information about the CLIM interfaces in a format that is compatible with
previous NonStop TCP/IP products. The object type name SUBNET, maintained for compatibility,
really refers to a home CLIM interface as seen from the host. SUBNET object names are generated
by CIPSAM and consist of “#SN” followed by a three-digit number. They are assigned to interfaces
when the interfaces are first reported and do not change as long as the CIP subsystem continues
running. The INFO SUBNET command displays the CLIM and interface name referenced by a
SUBNET object. Also, INFO PROCESS for the CIPSAM process displays information an application
would obtain from the INFO PROCESS command for the TCP6SAM process in NonStop TCP/IPv6,
including a DETAIL option (not supported in INFO PROCESS for the CIPMAN process). The INFO
PROCESS command for CIPSAM allows compatibility for applications written for the conventional
NonStop TCP/IP product.
NOTE: Many of the values for INFO PROCESS for CIPSAM are dummy values supplied for
backward compatibility only.
Conventional TCP/IP supplied detailed information on the TCP/IP process, which served as the
transport-service provider in that subsystem.
