Command Overview
To define $SYSTEM.RDFIMP as the location of the RDF software, enter the following
commands:
]SET RDF SOFTWARELOC $SYSTEM.RDFIMP
]ADD RDF
When the preceding command sequence is executed, all of the other RDF global
parameters are set to their default values, as follows. (In this list, \LONDON is the
system at which you issued the command sequence.)
PRIMARYSYSTEM: \LONDON
CONTROL SUBVOLUME: LONDON
LOGFILE : $0
UPDATERDELAY: 10
UPDATEROPEN: PROTECTED
UPDATEREXCEPTION: ON
UPDATERTXTIME: 60
UPDATERRTDWARNING: 60
NETWORK: OFF
NETWORKMASTER: OFF
REPLICATEPURGE: OFF
LOCKSTEPVOL: (omitted)
OWNER: (omitted)
Suppose you want to protect the volume $DATA01 on the primary system by
configuring an updater process for the volume $DATA1 and secondary image trail
$SECIT1 on the backup system (assuming that $SECIT1 was previously added to the
RDF configuration by way of an ADD IMAGETRAIL command). Also suppose the
updater process is to be named $UP01, is to run in CPUs 2 and 3 of the backup
system at the default priority of 160. In this example, we assume the ATINDEX value to
be the default value of zero. To configure the updater process, enter the following
commands:
]SET VOLUME PROCESS $UP01
]SET VOLUME CPUS 2:3
]SET VOLUME UPDATEVOLUME $DATA1
]SET VOLUME IMAGEVOLUME $SECIT1
]ADD VOLUME $DATA01
The SET VOLUME commands supply only values that pertain to the backup system
environment; it is not until you issue an ADD VOLUME command that the updater
process actually becomes associated with a particular volume on the primary system.
