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

If the backup volume names are not identical to the corresponding primary volume names, then
you will have to update every partitioned file and every file that has alternate keys on the backup
system so that each points to the correct volume name.
You can use INCLUDE and EXCLUDE lists to specify which files must be be protected by RDF. The
ALTER command supports only INCLUDE/EXCLUDE of files and does not support INCLUDEPURGE/
EXCLUDEPURGE. Wild cards in file names and subvolume names are not supported with this
command. For more information on INCLUDE and EXCLUDE lists, see Chapter 11 (page 271).
If you want Enscribe purge operations replicated, but you want to be selective and have some
purges replicated and others not, then you use INCLUDEPURGE and EXCLUDEPURGE to specify
what purges you want replicated. Please note that you must also have the RDF REPLICATEPURGE
attribute set to ON. For more details, see Chapter 11 (page 271).
The following RDFCOM commands configure an updater named $UP01 to run as a process pair
in CPUs 2 and 4 at a priority of 180. The updater will be associated with an secondary image
trail on the volume $IMAGA1. The name of the backup volume and the primary volume being
protected is $DATA01.
]SET VOLUME ATINDEX 0
]SET VOLUME PROCESS $UP01
]SET VOLUME CPUS 2:4
]SET VOLUME IMAGEVOLUME $IMAGA1
]SET VOLUME PRIORITY 180
]SET VOLUME UPDATEVOLUME $DATA01
]ADD VOLUME $DATA01
The mapping between the configured updater process and a particular primary volume is
accomplished by the ADD VOLUME command.
You can issue ADD VOLUME commands only when RDF is stopped.
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 350).
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)
