RDF System Management Manual for J-series and H-series RVUs (RDF Update 13)

4 Operating and Monitoring RDF
To operate and monitor RDF, you enter commands through two online utilities: the RDFCOM and
RDFSCAN interactive command interpreters. Through these utilities, you initiate communication
with RDF, request various RDF operations or information displays, and terminate communication
with the subsystem. This chapter, which is intended for system operators, explains how to use these
utilities by focusing on the following topics:
• “Running RDFCOM” (page 88), including:
Command syntax for starting an RDFCOM session◦
◦ Running RDFCOM interactively, noninteractively, and through a command file
◦ Using RDFCOM commands
◦ Requesting online help for RDFCOM commands
• “Running RDFSCAN” (page 98), including:
Command syntax for starting an RDFSCAN session◦
◦ Using RDFSCAN
◦ Using RDFSCAN commands
◦ Requesting online help for RDFSCAN commands
• “Performing Routine Operational Tasks” (page 101), including:
Displaying configuration attributes and operating statistics with RDFCOM◦
◦ Changing configuration attributes with RDFCOM
◦ Reading (monitoring) EMS messages with RDFSCAN
The syntax and functional descriptions of all RDFCOM and RDFSCAN commands appear in
Chapter 8 (page 175) and Chapter 9 (page 254), respectively.
For information about responding to error messages, handling failures, and stopping and restarting
RDF, see Chapter 5 (page 110). For information about the messages themselves, see Appendix C
(page 356).
Running RDFCOM
RDFCOM is an interactive command interpreter through which you begin a session and enter
requests to manage, operate, and control RDF. RDFCOM runs under the Guardian user interface
(normally the TACL command interpreter) to the NonStop operating system. To initiate communication
with RDFCOM, enter the keyword RDFCOM at the current TACL prompt. This begins an RDFCOM
session that lets you enter RDFCOM commands interactively, noninteractively, or through a command
file, as explained shortly.
Command Syntax for Starting an RDFCOM Session
To enter an RDFCOM session, use the following general command syntax. The specific attributes
you enter depend, of course, on the options you desire.
RDFCOM [/[IN command-file ] [,OUT output-file ]/ ]
[control-subvolume] ; [command ]
