RDF System Management Manual for J-series and H-series RVUs (RDF 1.10)

You must configure all updaters to use secondary image trails, thereby leaving the RDFVOLUME
(master image trail) exclusively for use by the master receiver (at index 0).
Creating a Configuration Command File
You can use the INFO * command with the OBEYFORM attribute to create a configuration command
file quickly and easily from an existing RDF configuration:
1. Redirect the output of the RDFCOM session from your terminal to the configuration command
file by issuing an appropriate OUT command. For example, to direct subsequent session output
to the configuration command file named RDF.INIT, enter the following command:
]OUT RDF.INIT
2. Issue an INFO * command with the OBEYFORM attribute:
]INFO *,OBEYFORM
RDFCOM lists the current attributes in the RDF configuration file to RDF.INIT in OBEY command
file format.
3. Issue another OUT command to redirect subsequent session output back to your terminal:
]OUT
For further information about configuration command files, see the example file in Appendix B
(page 340).
Configuration File Compatibility
Before running certain commands, RDFCOM compares its own version against the version of the
RDF configuration file to ensure that the configuration file is compatible with the current version of
the RDF software. If RDFCOM detects a difference, it prints the following message to the home
terminal and aborts the command:
RDFCOM version (version1) does not match the config file version (version2)
If that happens, you should make sure you are using the correct RDFCOM. If you are using the
correct version and you get this message, then you must reinitialize RDF.
If RDFCOM cannot determine the configuration file version, it prints the following message to the
home terminal and aborts the command:
RDFCOM version (version) does not match the config file version unknown
If that happens, you should make sure you are using the correct RDFCOM. If you are using the
correct version and you get this message, then you must reinitialize RDF.
Enabling RDF Operations
After you have copied all pertinent database files from the primary system to the backup system,
installed the RDF software on both systems, initialized and configured TMF on the primary and all
backup systems, and initialized and configured RDF, you can then start the TMF and RDF subsystems.
You must start TMF on the primary and all backup systems before you can start RDF.
Starting TMF
To start or restart TMF, issue the TMFCOM command START TMF. If you plan to start the applications
being protected by TMF before starting RDF, you can include the DISABLE BEGINTRANS attribute
in the START TMF command; this attribute prevents the applications from starting any transactions
until you issue the TMFCOM command ENABLE BEGINTRANS. For details about these TMFCOM
commands, see the TMF Reference Manual.
