Configuration Diagrams and Listings
Some of the important configuration listings include:
•
The Subsystem Control Facility (SCF) INFO command. Use the SCF INFO
command to display system configuration information for a specified device object
(for example, DISK, TAPE, or ADAPTER), including the current attribute values for
that object. Refer to the SCF Reference Manual for the Storage Subsystem for a
detailed description of the SCF INFO command.
•
The SCF STATUS command. Use the SCF STATUS command to display the current
status of a specified object. To display the status of all disks, use the SCF STATUS
DISK $* command. To display the status of all tape devices, use the SCF STATUS
TAPE $* command. Refer to the SCF Reference Manual for the Storage Subsystem
for a detailed description of the SCF STATUS command.
•
A process pair directory (PPD) listing. A PPD listing taken just after system and
application startup provides a quick reference of process names and their primary
and backup processors.
•
Listings from SCF commands (INFO, LISTDEV, STATUS) used to display the
status of terminals, printers, and communications lines. Refer to the SCF Reference
Manual for Himalaya S-Series Servers and the ServerNet Communications
Configuration and Management Manual for detailed information about these
commands for device types other than disk or tape.
•
Spooler configuration listings. The spooler configuration file shows the spooler
configuration and the names of the spooler components. The spooler interface
(SPOOLCOM) commands allow you to print the current configuration and the
spooler routing structure.
•
System configuration listings called CONFLIST and CONFTEXT. These listings
are generated during the system generation (SYSGEN or SYSGENR) phase of the
DSM/SCM program (DSM/SCM is used to generate a new system image and to
install new software releases.)
•
CONFLIST is the output file produced by SYSGENR. As SYSGENR processes
the CONFTEXT configuration file, it writes any action taken to the CONFLIST
file, including error and warning messages that are helpful to intermediate-level
and senior-level support personnel.
•
CONFTEXT is the configuration file used as input to SYSGENR that contains a
series of entries defining the Tandem NonStop Kernel operating system image
for all processors in the system, and is helpful to intermediate-level and senior-
level support personnel, and CEs. For G-series systems, the CONFTEXT file
consists of one or two paragraphs: DEFINED (optional) and
ALLPROCESSORS. Because SCF configures peripheral devices and I/O
processes, all other CONFTEXT files required for D-series systems are
removed.
•
DSM/SCM configuration reports. Standard reports extracted from the DSM/SCM
database and formatted by Structured Query Language (SQL) are available to
help DSM/SCM users analyze software and resources. Standard reports include
reports that list the current set of products for a selected system, reports that provide
detailed pictures of the contents of a given configuration by product, and reports that
can be used to determine the requisite interim product modifications (IPMs) to add
