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

]SET RECEIVER EXTENTS (3000,3000)
]ADD RECEIVER
You cannot start RDF until you have configured a master receiver process.
You can issue ADD RECEIVER commands only when RDF is stopped.
Purger Process
Use SET PURGER and ADD PURGER commands to configure the following purger attributes:
• CPUS primary-CPU : backup-CPU
• PRIORITY
• PROCESS
• RETAINCOUNT
• PURGETIME
The CPUS attribute specifies the processors in the backup system in which the purger is to run.
The PRIORITY attribute specifies the priority at which the purger will run. You should set the purger’s
priority higher than that of any application’s process and higher than that of any RDF updater
process.
The PROCESS attribute supplies a name for the purger process. You should specify a meaningful
mnemonic such as $PURG. The process name can be any unique valid process name up to six
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 RETAINCOUNT attribute specifies how many of the most recent image trail files will be retained
on disk for each image trail. The default value is 2. For details about the RETAINCOUNT attribute
and triple contingency, see Chapter 10 (page 260).
The PURGETIME attribute specifies the number of minutes the purger process waits between attempts
to purge redundant image trail files. The default value is 60.
To configure an RDF purger process named $PURG to run as a process pair in CPUs 0 and 2 of
the backup system at a priority of 185, and to ensure that at least six image trail files are always
retained on disk, issue the following commands:
]SET PURGER PROCESS $PURG
]SET PURGER CPUS 0:2
]SET PURGER PRIORITY 185
]SET PURGER RETAINCOUNT 6
]SET PURGER PURGETIME 30
]ADD PURGER
You cannot start RDF until you have configured a purger process.
You can issue ADD PURGER commands only when RDF is stopped.
Updater Processes
Use SET VOLUME and ADD VOLUME commands to configure the following updater attributes:
• ATINDEX
• CPUS primary-CPU : backup-CPU
• PRIORITY
• PROCESS
• IMAGEVOLUME
• UPDATEVOLUME
• INCLUDE
• EXCLUDE
