Thin Image pair resynchronization

Resynchronizing a Thin Image pair updates the S-VOL with the differential data and deletes the replaced data, the data in the pool. Resynchronizing a pair maintains the relationship between the P-VOL and S-VOLs.

The amount of time required for resynchronization depends on the following, even if the pair resynchronization rate is 100 percent:

• The amount of capacity the pool is using.
• The number of pairs being resynchronized concurrently.

  You can forward or reverse resynchronize Thin Image pairs. A forward resynchronization resynchronizes the S-VOL from the P-VOL. A reverse resynchronization restores the P-VOL from the S-VOL.

• Resynchronizing Thin Image pairs

  You can resynchronize Thin Image pairs that you have split or that the storage system has suspended.
