Procedure 13 To resynchronize one or more pairs
1. In the Storage Systems tree, click Replications > Remote Replications.
2. In the Remote Replications window, click the Cnt Ac-S Pairs tab, then select the pair to be
resynchronized.
3. From the Actions menu, click Remote Replications > Resync Pairs.
4. In the Resync Pairs window, ensure that the pair to be resynchronized appears in the Selected
Pairs table.
5. For Primary Volume Fence Level, specify whether the primary system rejects write operations
to the P-VOL when the pair is split due to an error.
•
- Status: The P-VOL cannot be written to only if the primary system is not able to change
S-VOL status to Suspended.
•
- Never: The P-VOL can always be written to.
•
- Data: The P-VOL cannot be written to.
For more information, see “Allowing I/O to the P-VOL after a split—Fence Level options”
(page 36) .
6. For Copy Pace, specify the number of tracks to be copied during the initial copy. Options are
3 or 15; 15 is the default. This option affects performance as follows:
3 is slow, improves performance and lowers impact to host I/O.
15 is fast, may lower performance and increase impact to host I/O.
7. For Copy Priority, enter the priority, or scheduling order, for the resync operation. You can
set priority from 0 to 256. The default is 32. For more on priority, see the descriptions in
“Priority for initial copy operations and scheduling order” (page 38) .
8. For Host I/O Time Stamp Transfer, specify whether the host I/O time stamp is transferred from
P-VOL to S-VOL. Enable transfers, Disable does not transfer; Disable is the default.
9. Click Finish.
10. In the Confirm window, review the settings and enter a task name in the Task Name box.
11. Click Apply to save your settings in the system.
