definition file created using the YKH2B command on the ISPF panel, the maximum length of the
prefix that can be specified is 16 characters.
DEVN(device-number- 1 , device-number-2) ~ <4-digit hexadecimal number>
Specify the first and last device numbers for the range for searching for copy pairs. For
device-number- 1 , specify the starting DEVN for the search range. For device-number-2, specify the
ending DEVN for the search range. For example, if 7000 and 7300 are specified for
device-number- 1 and device-number-2 respectively, copy pairs are searched in the volumes whose
DEVN is from 7000 to 7300, including the two end values.
If device-number-2 is smaller than device-number- 1 , device-number-2 is treated as the starting DEVN
of the scan range and device-number- 1 is treated as the ending DEVN of the scan range.
DAD(dad-id) ~ <DAD string>
The maximum length of the specification must be 44 - (13 + PREFIX-length).
CGNAME(name-of-TrueCopy-copy-group-with-HyperSwap-attribute) ~ <string of 8 or fewer
characters>
Specify the name of a CA copy group with the HyperSwap attribute.
HS({CHECK|NOCHECK})
Specify whether to check if HyperSwaps are enabled for the detected PPRC copy pairs.
CHECK
Acquires the UCB information (UCBHSWAP) of the P-VOLs of detected PPRC copy pairs and
checks whether HyperSwaps are enabled. Only those PPRC copy pairs for which UCBHSWAP
is set to ON are defined as a CA copy group with the HyperSwap attribute.
NOCHECK
Does not check whether HyperSwaps are enabled for the detected PPRC copy pairs. Instead,
all detected copy pairs are defined as a CA copy group with the HyperSwap attribute.
NOTE:
If a copy group definition file with the same name as the name specified in the CGNAME
parameter already exists, executing the YKH2B command overwrites the existing file with the
newly created file. To retain the existing file, specify in the CGNAME parameter a name that
is different from any existing copy group definition file name.
When you specify NOCHECK for the HS parameter, for the scan range, include only PPRC
TrueCopy copy pair volumes for which HyperSwap is enabled. If volumes of non-PPRC
TrueCopy copy pairs or volumes of PPRC copy pairs for which HyperSwap is not enabled are
included in the scan range, the copy pairs will be processed as PPRC copy pairs for which
HyperSwap is enabled. They will also be defined together as a TrueCopy copy group with
the HyperSwap attribute.
