Resynchronizing a Universal Replicator pair
Resynchronizing a pair updates the S-VOL with differential data that accumulated since the pair was split. After the pair is resynchronized, the S-VOL is again updated via the journals.
Prerequisites
Pair status must be PSUS or PSUE.
This operation can be performed only from the primary system.
Pairs suspended by the system (PSUE status) can be resynchronized after the error causing the suspension is corrected.
Review the following information before beginning the procedure:
The primary system does not resynchronize a pair that is suspended due to an error until the cause of error is resolved.
To resynchronize a pair
Open the Remote Replication window:
In Hitachi Command Suite: On the Resources tab, expand the Storage Systems tree, right-click the target storage system, and click Remote Replication.
In Device Manager - Storage Navigator: In the Storage Systems tree, click Replication > Remote Replication.
Select the UR Pairs tab, and then select the pairs to be resynchronized.
From the Actions menu, click Remote Replication > Resync Pairs.
In the Resync Pairs window, review the pairs in the Selected Pairs table. You can remove a pair from the table by selecting it and clicking Cancel.
For Copy Priority list, specify the scheduling order for resynchronizing selected pairs, between 1 and 256.
For Error Level, specify the system response if a failure occurs during this operation.
Mirror: Splits all pairs in the failed pair’s mirror.
LU: Splits only the specified pair or pairs that failed.
Click Finish.
In the Confirm window, review the settings and enter a task name in the Task Name box.
Click Apply to save your settings to the system.
