Description Item
Specify the
VOLUNIT
parameter of the
YKRESYNC
command:
•
Y
: Performs operations on a volume basis, even for an environment that
supports operations on a group basis during specification. To specify
this parameter after ATTIME suspend, execute the
YKSUSPND
command
with the
CANCEL
parameter specified.
•
N
: Performs operations on a group basis if this is supported by the
environment.
VolUnit
When the S-VOL is online, specify whether to make or resynchronize a copy
pair (default is
N
):
•
Y
: Makes or resynchronizes the copy pair even if the S-VOL is online.
•
N
: Does not make or resynchronize the copy pair if the S-VOL is online.
Overwrite ONLINE target volume
Specify whether the CA Open/MF Consistency attribute is to be changed
(using the Open/MF Consistency Preservation Function); the default is
N
.
•
Y
: Changes the Open/MF Consistency attribute. The value of the
Open/MF Consistency attribute of the loaded copy group attribute
information is applied.
•
N
: Does not change the Open/MF Consistency attribute. The value of
the Open/MF Consistency attribute of the loaded copy group attribute
information is not applied.
Update Open/MF
The
YKRESYNC
command terminates successfully when the instruction to the copy pair succeeded.
Even if the command has terminated successfully, make sure that the transition of the copy pair
status was performed, using the
YKQUERY
command or the
YKEWAIT
command. If there is a volume
whose status has not been changed, re-execute the
YKRESYNC
command with the
VOLUNIT
parameter specified for all the copy pairs.
NOTE: Remember the following while performing copy operations:
•
If the copy direction of copy groups is changed by using the
FORWARD
or
REVERSE
parameter
specification, make sure, before continuing the operation, that you specify
q
,
w
, or
e
in AC
on the Manage Copy Groups panel and acquire information about the copy direction after
the change.
•
While copying from a small capacity volume to a large volume in CA, CAA, or CAJ, if a
failure occurs on the secondary site, CA, CAA, or CAJ cannot be executed in the reverse
direction from the secondary site to the primary site. This copying function, copying from a
small volume to a large volume, should only be executed for data migration purposes.
•
You cannot specify the
SVOL(PERMIT)
and
REVERSE
parameters of
YKSUSPND
command
while copying from a small volume to a large volume is in progress in CA or CAA.
Executing YKDELETE
If
d
is specified in the AC column in the Manage Copy Groups panel, the
YKDELETE
command
to dissolve a copy pair is executed. In this case, the Confirm Execution Dissolve panel prompts
you to confirm whether to dissolve the copy pair. For details about the Confirm Execution Dissolve
panel, see
“Confirm Execution Dissolve Panel” (page 175) ).
