Online Installation and Initialization Without Stopping
RDF
5. Issue the STOP UPDATE command. Note, this command stops the updaters but
allows the extractor and receiver to continue to shipping and storing audit,
respectively.
6. Install the new RDF software in a different volume.subvolume from that housing
the current version of RDF that is running. For example, if you are upgrading to
T0346AAV, you might specify $system.rdfaav.
7. Run $system.rdfaav.RDFCOM and initialize a new RDF configuration, using
•
the suffix option (such as suffix "a")
•
the INITTIME option, using the timestamp calculated in Step 4 above
(11JUN2004 13:28).
Initialize RDF, backupsystem \RDF06, suffix a, inittime 11JUN2004 13:28
8. If you do not already have a copy of the configuration script used for the current
version of RDF, you can get it by starting the RDFCOM for that RDF subsystem
and using the INFO *, OBEYFORM command.
9. Use the same script to configure your new RDF subsystem, but you will need to
change the following:
a. Set SOFTWARELOC to $system.rdfaav
b. Set the extractor name(s) to a different name(s)
c. Set the monitor name to a different name
d. Set the receiver name(s) to different name(s)
10. Now start your new RDF subsystem:
] run $system.rdfaav.rdfcom rdf04a
] start RDF, update off
Note that you now have parallel sets of extractors shipping audit to parallel sets of
receivers for the two operating RDF subsystems, although each subsystem has its
own control subvolumes and its own imagetrail subvolumes.
11. When the extractor(s) for RDF04A have caught up, do the following:
a. Issue a STOP RDF command for the previous RDF subsystem.
b. Issue an UNPINAUDIT command for the previous subsystem.
c. Purge the previous control subvolumes on the primary and backup, as well as
the imagetrails for the previous subsystem.
d. Issue a START UPDATE command for the RDF04A subsystem.
You have now installed and started new RDF software without jeopardizing disaster-
recovery protection by having to stop RDF.
