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

IN command-file
specifies a command file from which RDFCOM commands are to be read. RDFCOM reads
132-byte records from the specified file until it encounters either the end-of-file mark or an
EXIT command.
If you do not specify the IN option, TACL automatically supplies the name of its current
default input file—usually the terminal from which you issued the RDFCOM command.
OUT output-file
specifies a file to which all output (other than prompts for entering RDFCOM commands) is
to be written. This file might receive listings requested by INFO, SHOW, and STATUS
commands, for example. It might also receive RDFCOM commands generated by the
OBEYFORM option of the INFO command.
If you do not specify the OUT option, TACL supplies the name of its current default output
destination—usually the terminal from which you issued the RDFCOM command.
If you specify a disk file that does not exist, an EDIT file (file code 101) having the name you
specified is automatically created, and RDFCOM output is directed to it. If you specify a disk
file that exists, this must be an EDIT file (file code 101); RDFCOM output is appended to that
file. If you omit the volume or subvolume portions of the file name specifier, the default is
your current volume or subvolume, respectively.
control-subvolume
is the name of the RDF control subvolume on $SYSTEM on the primary and backup systems,
as well as the subvolume on the image trail volumes on the backup system in which the
image trail files reside.
The control subvolume name is the same as the name of the primary system without the
backslash (and with a one-character suffix appended to it, if you included the suffix in the
INITIALIZE RDF command).
If you omit control-subvolume, RDFCOM assumes that the control subvolume name is
the same as the name of the local system on which RDFCOM is running (without the backslash
and with no suffix character appended to it).
command
is one or more RDFCOM commands; multiple commands are separated by semicolons (;). If
commands are present, RDFCOM executes them and then terminates without reading the
file specified in the IN option.
If commands are not present and no input file is specified, RDFCOM displays a right bracket (])
as a prompt to enter them.
Vertical bar (|) is the comment character, if you want to include comment lines in the configuration
file.
Using RDFCOM Interactively
When you use RDFCOM interactively, you conduct a continuous online dialog with it through
a series of prompts, commands, output displays, and messages.
Starting a Session
To start an interactive RDFCOM session, enter the RDFCOM keyword at your TACL prompt,
followed optionally by the name of the RDF control subvolume:
>RDFCOM [control-subvolume]
For example, to start a session on a primary system named SANFRAN, you would enter the
following command (assuming that no suffix character was specified in the INITIALIZE RDF
command):
>RDFCOM SANFRAN
