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

control-subvol
is the name of the RDF control subvolume on both primary and backup systems.
The control subvolume name is comprised of the primary system name of the RDF configuration
(without the backslash) plus the optional character suffix if you included one in the INITIALIZE
RDF command.
Where Issued
Primary or backup system.
Security Restrictions
None; anyone can enter the OPEN command.
RDF State Requirement
Before you can enter the OPEN command, RDF must have been initialized.
Usage Guidelines
Issue an OPEN command to select the RDF control subvolume to which any subsequent RDFCOM
commands (except another OPEN command) will apply.
Using the OPEN command is the same as specifying a control subvolume in the RDFCOM command
that begins a session. For example, the following two command sequences both accomplish the
same thing—identifying DENVER3 as the RDF control subvolume and then obtaining current status
information for that system:
• Sequence A:
>RDFCOM
]OPEN DENVER3
]STATUS RDF
• Sequence B:
>RDFCOM DENVER3
]STATUS RDF
Remember that, when you enter the RDFCOM command without specifying a control subvolume,
RDFCOM assumes that the control subvolume name is the same as that of the local system on which
the RDFCOM is running (without the backslash and with no suffix character). Thus, the OPEN and
STATUS commands shown in Sequence A and Sequence B will only work if a configuration file
exists on the control subvolume DENVER3.
You must use the OPEN command if the system you are entering commands on services more than
one RDF configuration, or is a backup system in your RDF configuration, and you did not specify
a control subvolume in the RDFCOM command that started the present session.
Examples
The following command, issued from a common backup system for the primary systems \TORONTO
and \DALLAS, identifies TORONTO as the RDF control subvolume for subsequent RDFCOM
commands:
]OPEN TORONTO
Having issued the above command, the next command obtains RDF status information for
\TORONTO:
]STATUS RDF
The following command identifies DALLAS as the RDF control subvolume:
]OPEN DALLAS
Having issued the above command, the next command requests RDF configuration information for
\DALLAS:
