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

5. Configure the network master subsystem with all the commands SET/ADD RDF, MONITOR,
UPDATER, NETWORK, and so forth. Do not perform a VALIDATE CONFIGURATION
yet.
6. Issue a VALIDATE CONFIGURATION command on each non-network master subsystem.
7. Issue a VALIDATE CONFIGURATION command on the network master subsystem.
NETWORK Attribute
This attribute, located in the RDF configuration record, specifies whether or not you are
configuring an RDF network.
To set this attribute, use this RDFCOM command:
SET RDF NETWORK {ON | OFF}
When this attribute is set to OFF (the default value), RDF takeover operations execute just as
they have in the past, and database consistency is not guaranteed for transactions that spanned
more than one primary system.
When this attribute is set to ON, the RDF subsystem can guarantee backup database consistency
across multiple RDF systems configured within an RDF network.
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
