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

Thus, within its configuration file, the network master has all necessary information about every
system in the RDF network (whereas the other systems have only a pointer enabling them to
obtain information about other systems in the network).
PRIMARYSYSTEM Network Attribute
This is the name of a primary system. It is set by this RDFCOM command:
SET NETWORK PRIMARYSYSTEM system-name
There is no default value. Each primary system within an RDF network must be unique within
the network. An RDF network cannot contain two or more RDF subsystems with the same
primary system (that is, it cannot contain RDF subsystems for \A to \B and \A to \C).
BACKUPSYSTEM Network Attribute
This is the name of the backup system associated with the specified primary system. It is set by
this RDFCOM command:
SET NETWORK BACKUPSYSTEM system-name
There is no default value.
REMOTECONTROLSUBVOL (RCSV) Network Attribute
The remote control subvolume (RCSV) is the name of the control subvolume used by the RDF
subsystem configured for the specified primary and backup systems. It is set by this RDFCOM
command.
SET NETWORK REMOTECONTROLSUBVOL subvolume-name
There is no default value.
PNETTXVOLUME Network Attribute
You only use this attribute when configuring the network master. On the master you must include
this attribute within every network configuration record (including the one for the master itself).
This attribute specifies the name of the volume on the particular primary system where the RDF
network master stores an audited network-synchronization file. The specified volume must be
a data volume protected by the RDF subsystem on the primary system and be configured to the
MAT. The PNETTXVOLUME volume is set by this RDFCOM command.
SET NETWORK PNETTXVOLUME volume-name
There is no default value.
Adding the Network Record
When you have finished setting the attributes for a given RDF subsystem, you add that
information to your current configuration file with this RDFCOM command.
ADD NETWORK
RDF Network Synchronizer (RDFNET) Process
RDF/IMPX and RDF/ZLT include an RDF executable process, the RDFNET process, that can only
be configured within a network master RDF subsystem (and can therefore only be started on the
network master’s primary system).
This process provides a synchronization point within the image trails of all backup systems in
an RDF network. The process does that by updating an audited file named ZRDFNETX on the
primary system of each RDF subsystem in the RDF network. The overhead of this process should
be transparent because the RDFNET process only starts a single transaction every 15 seconds
and only executes a single update against the ZRDFNETX file on the primary system of each
RDF subsystem in the RDF network.
The fully-qualified name of the ZRDFNETX file for each system is:
