Complete this task to resynchronize (apply incremental changes
on the source volume to) a FlashCopy® target volume. After the initial FlashCopy operation,
only data that has changed on the source volume since the last resynchronization
operation was performed is copied to the target volume.
The change recording option and the persistent option must have been
enabled on the FlashCopy volume
pair.
You can resynchronize a FlashCopy target volume to create
a new point-in-time copy of your data without waiting to copy an entire volume
for each point-in-time copy. Instead, only tracks that have changed on the
source volume since the last resynchronization operation was performed are
copied to the target volume.
Perform the following steps to resynchronize
a FlashCopy relationship between a source volume and target volume:
- In the navigation, select . A list of FlashCopy volume
pairs is displayed. Select one or more FlashCopy pair on which to perform
an action.
Note: All storage complexes that are listed in the drop-down list
are based on the storage complexes that were added during the configuration
process. If you added a 2105 Copy Services domain, it is listed as a storage
complex. All relationships that are displayed can be source or target volumes
from the selected domain.
- Select Resync target from the Select
Action drop-down list. Click Go.
- Select the copy options for the FlashCopy target volumes that will
be resynchronized after data is copied from the source volumes. You must select
whether to enable or disable the Enable change recording, Permit
FlashCopy to occur if target volume is online for host access,
and Inhibit writes to target volume options.
- When you have finished selecting your options, click OK to
complete the task, or click Cancel to exit without performing the task.
