Pressing the Enter key starts the background job for scanning the P-VOL.
The volumes within the range specified in Device Num are scanned. If an invalid character is
specified, or if the value specified for Start is greater than the value specified for End, an error
message prompts you to re-enter the values.
The values specified here are used during the execution of the background job. JCL uses a value

Before executing a scan, create a disk configuration definition file for the search-target storage
system in the Discover HP Storage System panel.
When the background scanning job is completed, the configuration information for the scanned
copy pair is saved in the copy group definition file. A name that conforms to the value in
Configuration File Prefix, CA Copy Group ID, and TCA Copy Group ID or BC Copy Group ID in the
Set Defaults panel is assigned to the file using the following format:
prefix.GRP.ggggggnn
Where:
gggggg: Copy group name
nn: 2-digit serial number beginning with 00
A copy group definition file is created as follows:
CA copy groups: A single copy group definition file is created for all searched copy pairs.
TCA copy groups: A copy group definition file is created for each C/T group.
BC copy groups: A single copy group definition file is created for all searched copy pairs.
To check the created copy group definition file, press the F4=Refresh key in the Copy Group
Selection List panel.

Description
Specify the Start and End of the device number range for scanning the
P-VOL of the PPRC copy pair, using hexadecimal numbers in ascending
order (required).
NOTE: The device number range cannot be omitted. To scan only a
single volume, specify the same volume for Start and End.
When creating a CA copy group definition file, you can check whether
HyperSwap is enabled for the detected PPRC copy pair.
If the search range contains both volumes for which HyperSwaps are
enabled and volumes for which HyperSwaps are not enabled, by
specifying CHECK, you can prevent PPRC copy pairs, for which
HyperSwaps are enabled, from being defined in the CA copy group
definition file.
If the search range does not contain volumes for which HyperSwap is
enabled, specify NOCHECK.
CHECK: Acquires the UCB information (UCBHSWAP) of the P-VOLs
of the detected PPRC copy pairs, and checks whether HyperSwaps
are enabled. PPRC copy pairs for which UCBHSWAP is set to ON
are not defined in the CA copy group definition file.
NOCHECK: Does not check whether HyperSwap is enabled for the
detected PPRC copy pairs. All detected copy pairs, even if
HyperSwaps are enabled for them, are defined as CA copy groups
without the HyperSwap attribute.
The initial display is NOCHECK.
