Command Overview
Security Restrictions
You can issue the SET VOLUME command only if you are a member of the super-user
group.
RDF State Requirement
You can only enter SET VOLUME commands if you have not already used the ADD
VOLUME command to apply the configuration parameters for the associated updater
process to the RDF configuration file. For further information, see the ADD command
description.
Usage Guidelines
The SET VOLUME command enters the parameter values specified for the updater in
this command into the RDF configuration table in memory. This table serves as an input
buffer only, 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 VOLUME 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, as follows:
•
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.
Once an updater process has been added to the RDF configuration, you cannot alter its
INCLUDE or EXCLUDE parameters. If you must do so, you have to delete the updater
and then add it back to the configuration as described in Section 11, Subvolume- and
File-Level Replication.
You can specify a maximum of 100 INCLUDE and EXCLUDE parameters for each
volume, in any combination.
Unlike the behavior of other SET parameters, successive INCLUDE or EXCLUDE
parameters do not supersede preceding ones in the RDF configuration memory table
(they merely extend the include and exclude lists for the particular data volume).
As with SET parameters for all RDF object types, specified INCLUDE and EXCLUDE
parameters remain in the RDF configuration memory table even after you add the
updater to the configuration. This can be useful, for example, if the same INCLUDE
and EXCLUDE parameters apply to multiple volumes. If the parameters vary from one
volume to the next, however, you must remember to issue a RESET VOLUME
