Pair command
on: A copy pair is created even when the
S-VOL (or P-VOL when Reverse is specified)
is online.
off: A copy pair is not created if the S-VOL
(or P-VOL when Reverse is specified) is
online. If the volume is online, no error
occurs during an operation performed on
C/T groups, but an error message is issued
during an operation performed on pairs.
Note: Overwrite ONLINE target volume
makes up a copy pair even if the primary
volume in the configuration definition is
online. Ensure that the primary volume is
not being used.

Notes:
1.
When a split operation is performed on Cnt Ac-S, Cnt Ac-A, or Cnt Ac-J pairs or C/T groups,
the Direction option is inactive because the reverse direction to the current copy direction cannot
be specified.
2.
When a split operation is performed on Cnt Ac-A or Cnt Ac-J copy groups, if the value specified
for the Direction option is different from the current copy direction, Synchronization cannot be
specified.
3.
The default value displayed for the Secondary Mode option is the value defined for the copy
group to which the target copy pair belongs.
4.
When a split operation is performed during I/O processing of the primary volume, it might result
in incomplete data in the secondary volume. Make sure that I/O processing for the primary
volume is not being performed.
When performing operations on EXCTGs (mainframe systems)
The following conditions apply when performing operations on an EXCTG:
•
You must execute the operation on the EXCTG per EXCTG. If you execute the operation per pair
or per CTG, the consistency of the EXCTG configuration might be compromised.
•
When you execute the Delete operation on the EXCTG, do not specify the Force option. If you
specify the Force option, the consistency of the EXCTG configuration might be compromised.
About copy pair status
Copy pair status is a value that indicates the status of a copy pair, as defined by Replication Manager.
To view a list of copy pair statuses, see “
The copy pair statuses displayed are determined by the combination of the copy pair states of the
primary and secondary volumes. Although two copy pairs might have the same copy pair status, the
combination of copy pair states of their primary and secondary volumes might differ. For details on
copy pair statuses and combinations of copy pair states for primary and secondary volumes, see
“
