RDF Re-Initialization in a Network Environment
1. You must validate all non network master subsystems before validating the
network master’s subsystem.
2. Because you cannot validate the network master until all non network master
subsystems have been validated, you cannot start the network master until all non
network master subsystems have been validated.
3. If you have validated a non network master, you are allowed to start that
subsystem even though the network master has not been validated.
See Appendix C for the error messages that can occur during validation steps.
RDF Re-Initialization in a Network Environment
For any number of reasons you may choose to stop some of your RDF network
subsystems and reinitialize them. This can be done without impacting the other
subsystems in the RDF network. When you reconfigure those subsystems after
initialization, there are several considerations.
Network Master Subsystem Initialization
When you reconfigure the subsystem, the network record must list all the non network
master systems and the information for each system in the network record must be
identical to the previous configuration. If not, validation will fail and you will not be able
to start the subsystem.
Non Network Master Subsystem Initialization
If you reconfigure the RDF subsystem of a non network master:
1. The network configuration record must point to the network master of the RDF
network.
2. You must ensure that the updater responsible for the PNETTXVOLUME is also
configured to the same image trail as that listed in the network master’s network
configuration record. Otherwise, validation will fail and you will be unable to start
the newly configured subsystem.
Note. It is strongly recommended that you validate the configurations of all RDF subsystems
in your RDF network with the RDFCOM VALIDATE CONFIGURATION command before you
attempt to start any. This would then guarantee that your entire RDF network is configured
correctly before you start any of the individual RDF subsystems.
Note. If you must change the PNETTXVOLUME, the ImageTrail, or the RDFVOLUME of any
subsystem in your RDF network, then you must stop and reinitialize all of the RDF subsystems
in that network.
