Initializing RDF
To a TMF Shutdown Timestamp
If TMF was running previously on the primary system and did not need to be initialized
and configured, you can initialize RDF to a timestamp that reflects the time of the last
TMF shutdown.
To issue the INITIALIZE RDF command without first initiating an RDFCOM session,
enter the command in the following format in response to the TACL prompt. In the
TIMESTAMP parameter, be certain to specify the exact time (to the minute) that TMF
was last shut down. You determine the appropriate timestamp by examining previous
TMF messages in the EMS log. In this example, the TIMESTAMP parameter specifies
1:32 p.m., January 7, 1999:
>RDFCOM;INITIALIZE RDF, BACKUPSYSTEM \CHICAGO,
SUFFIX A, TIMESTAMP 7JAN1999 13:32
To issue the INITIALIZE RDF command from within an RDFCOM session, enter the
following in response to the RDFCOM prompt:
]INITIALIZE RDF, BACKUPSYSTEM \CHICAGO, SUFFIX A,
TIMESTAMP 7JAN1999 13:32
If the INITIALIZE RDF commands in this discussion were issued from the primary
system \DALLAS, RDF would respond by creating a configuration file in the control
subvolume named $SYSTEM.DALLASA.CONFIG.
Without a TMF Shutdown Timestamp
If you have just installed (or deleted and reinstalled) TMF so that it starts at relative
byte address (rba) 0 in audit trail file sequence number 1, you should now issue an
INITIALIZE RDF command without the TIMESTAMP parameter at the TACL prompt on
the primary system:
>RDFCOM; INITIALIZE RDF, BACKUPSYSTEM \BOSTON, SUFFIX A
Note that when you begin an RDFCOM session on a system in which RDF has never
been previously initialized (such as \PRIMSYS, for example), RDFCOM responds with
the following prompt:
***Warning*** The control subvolume PRIMSYS is not presently
***Warning*** configured for an RDF primary system.
You must use the OPEN command to open an RDF CONFIG file in
an existing RDF control subvolume, or you must initialize a
new RDF configuration with the INITIALIZE RDF command.
To continue with the session, you must either enter an INITIALIZE RDF command, or
use the OPEN command as directed in Section 8, Entering RDFCOM Commands.
