HP XP P9000 for Business Continuity Manager Software Reference Guide

does not contain any P-VOLs in the detected PPRC copy pairs or S-VOLs corresponding to the
P-VOLs, copy pairs are still defined. If this occurs, a warning message is issued.
A copy group definition file is created as follows:
• For a CA copy group with the HyperSwap attribute: A single copy group definition file is
created for all detected copy pairs.
Parameters
PREFIX(prefix) ~ <prefix of 25 or fewer characters>
Specify the prefix of a disk configuration definition file that has already been created by Business
Continuity Manager and of the copy group definition file to be created. When using a copy group
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.
