Configuring RDF
Updater Processes
Use SET VOLUME and ADD VOLUME commands to configure the following updater
parameters:
•
ATINDEX
•
CPUS primary-CPU : backup-CPU
•
EXCLUDE
•
IMAGEVOLUME
•
INCLUDE
•
PRIORITY
•
PROCESS
•
UPDATEVOLUME
You must configure an updater process for each primary system volume to be
protected by RDF.
The CPUS option value specifies the processors in the backup system in which the
updater will run.
The IMAGEVOLUME option value associates this updater process with a specific
image trail you have previously added to the RDF configuration. You cannot add this
updater process, associating it to an image volume, unless you have already added
the image trail with the ADD IMAGETRAIL command. Also, the ATINDEX of this
updater must match the ATINDEX of the associated image trail.
The PRIORITY option value specifies the priority at which the updater will run. You
should set the updater’s priority higher than that of any application’s process but less
than the priority of the RDF receiver process.
The PROCESS option value supplies a name for the updater process. You should
specify a meaningful mnemonic such as $UP01. The process name can be any unique
valid process name up to 5 characters, including the $ symbol. However, you cannot
specify HP reserved process names that are of the form $X*, $Y*, or $Z*, in which *
is any alphanumeric string.
The UPDATEVOLUME option value specifies the name of the disk volume on the
backup system that corresponds to a particular volume on the primary system. This
parameter enables you to use different volume names on the backup system than are
being used on the primary system, if you so desire.
