RDF System Management Manual for J-series and H-series RVUs (RDF 1.10)

STOP RDF
The STOP RDF command shuts down RDF.
STOP RDF { [, DRAIN ] }
{ [, REVERSE ] }
DRAIN
causes the following actions:
• All TMF audit records up to the time the command is entered are stored in the image trails
on the backup node.
• The RDF processes shut down in a manner similar to when a stop TMF record is encountered
in the audit trail.
• Each updater shuts down after it has applied all audit records up to the stop point.
• The purger process reports event 852, indicating that all updaters have stopped and the
drain has completed.
REVERSE
causes RDF to replicate all audit records up to the time the command was issued, then run the
configured reverse trigger program.
You must stop all transaction activity on the primary system before issuing the STOP RDF,
REVERSE command. If there is active transaction activity on the RDF-protected database, the
database could lose integrity or data could be lost when RDF is initialized and started in reverse.
To emphasize these risks, RDFCOM displays this challenge in response to STOP RDF, REVERSE
commands:
**** All transaction activity in this RDF environment
**** must stopped before the STOP RDF, REVERSE command
**** is executed.
**** The REVERSE TRIGGER will be run even if the primary
**** application has not yet been stopped.
**** Are you sure you want to continue ? (yes/no)
To proceed you must type “yes” (not “y” or carriage return). “no” cancels the command and
returns you to the RDFCOM command prompt. Any other response results in this question:
**** Are you sure you want to continue ? (yes/no)
Again you must type either “yes” or “no”.
Where Issued
You can issue the STOP RDF, DRAIN and STOP RDF, REVERSE commands only at the primary
system.
Security Restrictions
You can issue the STOP RDF command if you are a member of the super ID group that initialized
RDF and have a remote password from the RDF primary system to the backup.
RDF State Requirement
You can issue the STOP RDF, DRAIN and STOP RDF, REVERSE commands only while RDF is running
and update is on.
Usage Guidelines
The decision to stop RDF is a management decision that should be carefully planned and performed.
Operators should never issue the STOP RDF command strictly on their own initiative.
To execute a planned RDF shutdown, you should generally use the STOP TMF command rather
than STOP RDF. Issue the STOP TMF command at the primary system while the communications
