RDF System Management Manual for H-Series RVUs (RDF 1.8)

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 101), 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 109), including:
— Command syntax for starting an RDFSCAN session
— Using RDFSCAN
— Using RDFSCAN commands
— Requesting online help for RDFSCAN commands
• “Performing Routine Operational Tasks” (page 113), including:
— Displaying configuration parameters and operating statistics with RDFCOM
— Changing configuration parameters with RDFCOM
— Reading (monitoring) EMS messages with RDFSCAN
The syntax and functional descriptions of all RDFCOM and RDFSCAN commands appear in
Chapter 8 (page 173) and Chapter 9 (page 245), respectively.
For information about responding to error messages, handling failures, and stopping and
restarting RDF, see Chapter 5 (page 121). For information about the messages themselves, see
Appendix C (page 335).
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 parameters
you enter depend, of course, on the options you desire.
RDFCOM [/[IN command-file ] [,OUT output-file ]/ ]
[control-subvolume] ; [command [; command ]... ]
RDFCOM
is an implicit RUN command, instructing the TACL command interpreter to run the RDFCOM
utility program.
