Description
Item
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
.
Device Num
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.
HS
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
indicated in the
“Set Defaults Panel (Prefix and DAD ID Settings)” (page 27)
.
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.
