CASpecify whether to transfer the
writing timestamp to the S-VOL
when the copy type is CA
(timestamp transfer mode).
TIMESTAMP
• Y: Transfers the timestamp to the
S-VOL. Specify this item only
when you are using the CAJ
ATTIME suspend function in a
4x4x4 Cascade configuration
or a 3DC Cascade
configuration.
• N: Does not transfer the
timestamp to the S-VOL.
CASpecify whether the Open/MF
Consistency Preservation Function
OPEN/MF
• When the YKMAKE
command is executed
is to be used when the copy type is
CA.
• When the YKRESYNC
command is executed
Y: Uses the Open/MF Consistency
Preservation Function (Open/MF
Consistency attribute setting).
(with OPENMFUPDATE
specified)
N: Does not use the Open/MF
Consistency Preservation Function.

Business Continuity Manager can dissolve copy pairs (by executing the YKRECVER or YKDELETE command).
2
Although you can change the definitions in Business Continuity Manager by specifying HS or NONE for Linkage Option,
the changes will not be applied to the host and storage system. If the definitions are changed on the host or in the storage
system, make sure that you change the definitions in Business Continuity Manager so that they match the definitions on
the host and in the storage system.
3
If not all of the volume statuses are SIMPLEX, processing might not execute correctly.
4
Do not specify 0 for MIRROR ID when using a CAJ copy group and a Continuous Access Synchronous copy group in
either the 3DC Cascade configuration or the 3DC Multi-Target configuration. Note also that when a 3DC Multi-Target
configuration or a 2DC configuration with HyperSwap and CAJ is used, the mirror ID cannot be the same as any other
mirror ID assigned to another CAJ copy group.
5
When a copy group in which Y is set to FREEZE SCP changes to a failure suspension status, execute the YKRUN command
to cancel the SCP status. If you do not cancel SCP status, the update I/O flow from the host is held for a long period of
time. You cannot use the SCP delay time that was set using the Remote Web Console to change the hold period for
update I/O. Specification of Y is valid only for a CA copy group for which a consistency group ID is specified.

When executing the YKRESYNC command, specify the VOLUNIT or DEVN parameter.
If the Enter key is pressed before all required attributes have been specified, an error message is
displayed.
“Default values for each copy type” (page 84) indicates the default values for each copy type:
