NETWORKMASTER Attribute
This attribute, located in the RDF configuration record, specifies whether or not the particular
system is the master of the RDF network. Each RDF network has one, and only one, network
master.
To set this attribute, use this RDFCOM command:
SET RDF NETWORKMASTER {ON | OFF}
When this attribute is set to OFF (the default value), the particular system is not the network
master.
When this attribute is set to ON, the particular system is the network master of the RDF network.
If this attribute is set to ON, the NETWORK attribute must also be set to ON.
Network Configuration Record
This configuration record contains some or all of these network attributes:
PRIMARYSYSTEM
system-name
BACKUPSYSTEM
system-name
REMOTECONTROLSUBVOL
subvolume-name
PNETTXVOLUME
volume-name
If you are configuring the network master RDF subsystem, you must include a network
configuration record for every RDF subsystem in the RDF network (including the network master
itself). Each of those records must include these attributes:
Name of the primary system. PRIMARYSYSTEM
system-name
Name of the associated backup system. BACKUPSYSTEM
system-name
Name of the primary system’s remote control subvolume. REMOTECONTROLSUBVOL
subvolume-name
Name of the primary system volume on which the RDF
subsystem stores an audited network synchronization file. PNETTXVOLUME
volume-name
If you are configuring a non network master RDF subsystem, you must include a single network
configuration record containing these attributes:
Name of the network master’s primary system. PRIMARYSYSTEM
system-name
Name of the network master’s backup system. BACKUPSYSTEM
system-name
Name of the network master’s remote control subvolume. REMOTECONTROLSUBVOL
subvolume-name
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
