RDF System Management Manual for H-Series RVUs (RDF 1.8)

and so these values do not affect the subsystem until they are applied to the RDF configuration
file with the ADD command.
For ATINDEX values greater than 0, the specified value must match the audit-trail number of a
configured auxiliary audit trail. If you specify SET RECEIVER ATINDEX 2, for example, there
must be a configured auxiliary audit trail AUX02.
Furthermore, RDF objects with a particular ATINDEX value greater than 0 must together constitute
a complete set:
• If there is an extractor with an ATINDEX value of 1, there must also be a receiver with an
ATINDEX value of 1.
• If there is a receiver with an ATINDEX value of 1, there must also be a secondary image trail
with an ATINDEX of 1.
• An updater with an ATINDEX value of 1 must be protecting a primary system data volume
configured to auxiliary audit trail AUX01, and its secondary image trail must also have an
ATINDEX value of 1.
Examples
To configure a receiver process named $RCV0 to run in CPUs 0 and 1, with the RDF master
image files residing on the volume $IMAGE and having primary and secondary extents of 1000
pages each, issue these commands:
]SET RECEIVER PROCESS $RCV0
]SET RECEIVER CPUS 0:1
]SET RECEIVER RDFVOLUME $IMAGE
]SET RECEIVER EXTENTS (1000,1000)
]ADD RECEIVER
By default, in this example the receiver process is associated with the MAT and will run at a
priority of 165.
To configure an auxiliary receiver process named $RCV1 associated with the auxiliary audit trail
AUX01 to run in CPUs 2 and 3, issue these commands:
]SET RECEIVER PROCESS $RCV1
]SET RECEIVER ATINDEX 1
]SET RECEIVER CPUS 2:3
]ADD RECEIVER
By default, in this example the auxiliary receiver process will run at a priority of 165.
SET TRIGGER
The SET TRIGGER command sets trigger parameters within the RDF configuration memory
table. The supplied values are not applied to the RDF configuration file, however, until you issue
an ADD TRIGGER command. The trigger type (REVERSE or TAKEOVER) is specified in the
ADD TRIGGER command.
SET TRIGGER trigger-option
where trigger-option is:
{PROGRAM program-file }
{INFILE infile }
{OUTFILE outfile }
{CPUS primary-CPU : alternate-CPU }
{PRIORITY priority }
{WAIT |NOWAIT }
program-file
is the name of any Guardian object file. This object file is run once RDF has reached a particular
state, either after a STOP RDF, REVERSE, or TAKEOVER operation. program-file must
be a properly-formed Guardian disk file name. The file does not have to exist. This parameter
