1 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.

7 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.

If you define a new copy group in the Add Copy Group panel, and you then return to the Copy
Group Attributes panel and press the
F12=Cancel key, display returns to the Copy Group Detail
