Table 86 Contents of the Resync Options Panel (continued)
DescriptionItem
When the S-VOL is online, specify whether to make or resynchronize a copy
pair (default is N):
Overwrite ONLINE target volume
• 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.
Specify whether the CA Open/MF Consistency attribute is to be changed
(using the Open/MF Consistency Preservation Function); the default is N.
Update Open/MF
• 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.
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 171)).
NOTE: Do not execute the YKDELETE command during planned outage operation (when switching
the P-VOL and S-VOL). To dissolve the copy pair, switch the P-VOL and S-VOL again, return the
P-VOL to the primary site (restore normal operation), and then dissolve the copy pair.
Executing YKWATCH
If w is specified in the AC column in the Manage Copy Groups panel, the YKWATCH command to
monitor the volume status transition will be executed and the Watch Options panel for specifying
parameters of the YKWATCH command is displayed. The value is used as a background job for
submitting. JCL uses a value indicated in the Set Defaults panel.
Figure 130 (page 166) shows the Watch Options panel.
