You can resynchronize Thin Image pairs that you have split or that the storage system has suspended.
Resynchronizing pairs does the following:
- Updates the S-VOL so that it is again paired with the P-VOL.
- Frees up the P-VOL’s snapshot differential data for that P-VOL to reuse.
Note: If the amount of snapshot data in selected
P-VOLs or the total number of pairs in selected snapshot groups exceeds 32,768, an
error message appears when attempting to perform pair tasks.
- You must have the Storage Administrator (Local Copy) role.
- In the Explorer pane, click Storage Systems, expand the storage system tree, expand Replication, and then click Local Replication.
- In the Local Replication window, select a P-VOL in the TI Root Volumes tab or a snapshot group in the Snapshot Groups tab.
- Click Operate TI Pairs.
- In the TI Pairs window, select the pair you want to resynchronize, and then click Resync Pairs.
-
For
Resync Type, select
Normal Copy (Primary > Secondary) for full forward resynchronization of data from the P-VOL to the S-VOL.
