The Copy Group Configuration Check Function
To determine if the copy group definition and the actual copy pair configuration match, execute
the YKQUERY command with the VERIFY parameter specified. This check function detects user
definition mistakes by verifying that the following are true:
• The disk configuration information (storage system serial number, control unit number, or
command control address) for the actual P-VOL and S-VOL matches the copy group definition.
• Copy pairs in the copy group definition are also included in the specified consistency group.
• Copy pairs in the specified consistency group are included in the copy group definition.
• Copy pairs in the specified consistency group are included in the copy group definition.
• The copy type of the actual volume matches the copy group definition.
• For Continuous Access Synchronous consistency groups, the Open/MF Consistency attribute
definitions match the actual attributes.
Table 20 (page 81) shows the items checked for each copy type, when the VERIFY parameter is
specified.

If some copy pairs in the specified C/T group are not included in the copy group definition, note that when you attempt
to operate on copy pairs by copy group, the operation will apply to all the copy pairs in the C/T group, including those
not included in the copy group definition.

A copy pair can only be checked if it belongs to the same CU as the copy group definition. If a copy pair belongs to a
different CU, it cannot be checked.
Legend:
C: Checked.
H: Copy pairs that are in conflict with the definition are handled as SIMPLEX.
N: Not checked.
Copy Group Definition File Generation Function Using CSV Files
In Business Continuity Manager, copy group information can be defined using the copy pair
information described in files composed of comma-separated values (CSV files). By using CSV
files, even a large-scale copy group configuration can easily be defined or updated. In addition,
because processing to define copy groups can be executed as a batch job with a CLI command,
the operational load can be reduced.
